The OPM technology is based on the cognitive networking principles that are advanced from traditional wireless networking by the opportunistic utilization of both spectrum bandwidth and mesh station/radio availability. Traditional wireless networking assumes that those resources can be predetermined, and the protocol stacks from wire-line networks can be re-used. For example, in the traditional stack, the MAC (Media Access Control) layer allocates spectrum resources to wireless links; and the network layer sets up a network routing path from source to destination based on the overall network topology. In large-scale wireless systems, the use of this stack results in a network that is unable to respond to volatile spectrum availability which can be typical in unlicensed bands where interference prevails.

In one scenario, Station A can communicate with Station B. Station C can also communicate with Access Point Station B. However, Stations A and C cannot communicate with each other as they are out of range of each other. In wireless networking, the hidden node problem or hidden terminal problem occurs when a node can communicate with a wireless access point (AP), but cannot directly communicate with other nodes that are communicating with that AP. This leads to difficulties in medium access control sublayer since multiple nodes can send data packets to the AP simultaneously, which creates interference at the AP resulting in neither packet getting through. Although some loss of packets is normal in wireless networking, and the higher layers will resend them, if one of the nodes is transferring a lot of large packets over a long period, the other node may get very little goodput. Practical protocol solutions exist to the hidden node problem.

In contrast to the stations in an infrastructure- mode network, the stations in a wireless ad hoc network communicate directly with one another, i.e. without a dependence on a distribution point to relay traffic between them. In this form of peer-to-peer wireless networking, the peers form an independent basic service set (IBSS). Some of the responsibilities of a distribution point such as defining network parameters and other "beaconing" functions are established by the first station in an ad- hoc network.

The "state of the art" smartclocks come with multi-touch screens, full color displays, real time monitoring for problems, wireless networking and over the air updates. Some of the smartclocks use front-facing cameras to capture employee clock-ins to deter "buddy clocking" or "buddy punching", whereby one employee fraudulently records the time of another. This problem usually requires expensive biometric devices. With the increasing popularity of cloud-based software, some of the newer time clocks are built to work seamlessly with the cloud.

The purpose of most transmitters is radio communication of information over a distance. The information is provided to the transmitter in the form of an electronic signal, such as an audio (sound) signal from a microphone, a video (TV) signal from a video camera, or in wireless networking devices, a digital signal from a computer. The transmitter combines the information signal to be carried with the radio frequency signal which generates the radio waves, which is called the carrier signal. This process is called modulation.

Lucent continued to be active in the areas of telephone switching, optical, data and wireless networking. On April 2, 2006, Lucent announced a merger agreement with Alcatel, which was 1.5 times the size of Lucent. Serge Tchuruk became non-executive chairman, and Russo served as CEO of the newly merged company, Alcatel-Lucent, until they were both forced to resign at the end of 2008. The merger failed to produce the expected synergies, and there were significant write-downs of Lucent's assets that Alcatel purchased.

Red Hat initiated the NetworkManager project in 2004 with the goal of enabling Linux users to deal more easily with modern networking needs, particularly wireless networking. NetworkManager takes an opportunistic approach to network selection, attempting to use the best available connection as outages occur, or as the user roams between wireless networks. It prefers Ethernet connections over “known” wireless networks, which are preferred over wireless networks with SSIDs to which the user has never connected. The user is prompted for WEP or WPA keys as needed.

Space is another characteristic of wireless networking. Wireless networks offer many advantages when it comes to difficult-to-wire areas trying to communicate such as across a street or river, a warehouse on the other side of the premises or buildings that are physically separated but operate as one. Wireless networks allow for users to designate a certain space which the network will be able to communicate with other devices through that network. Space is also created in homes as a result of eliminating clutters of wiring.

Cloudlets aim to support mobile applications that are both resource-intensive and interactive. Augmented reality applications that use head-tracked systems require end-to-end latencies of less than 16 ms. Cloud games with remote rendering also require low latencies and high bandwidth. Wearable cognitive assistance systems combine devices such as Google Glass with cloud-based processing to guide users through complex tasks. This futuristic genre of applications is characterized as “astonishingly transformative” by the report of the 2013 NSF Workshop on Future Directions in Wireless Networking.

He has been an invited to speak in over ten countries on the topic of technology in education. Nicholas Burbules' most recent work centers on Ubiquitous Learning, a concept that draws out the emergence of "any time, anywhere" learning potential made possible by increased use of handheld and portable devices, along with pervasive wireless networking. This involves a shift in ubiquity, as the traditional divide between formal and informal contexts of learning breaks down. Technological as well as social, cultural, and institutional changes mean that learning is a continuous possibility across spatial and temporal barriers.

Community-based multi-hop wireless networking is a disruptive force on mainstream DSL and cable modem wireline networks. In the true spirit of the Internet, it allows free flow of information without any moderation or selective rate control (see network neutrality). Between 2003 and 2007, Bahl and his team at Microsoft Research invented several important technologies that made wireless mesh networking feasible. Their research, which was highly publicized in mainstream press, popularized the idea of community networks that would grow organically when neighbors connect their home Wi-Fi networks together via wireless meshes.

Temporal Key Integrity Protocol (TKIP ) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware. This was necessary because the breaking of WEP had left Wi-Fi networks without viable link-layer security, and a solution was required for already deployed hardware. However, TKIP itself is no longer considered secure, and was deprecated in the 2012 revision of the 802.11 standard.

In November 1997, Gary Glitter took a laptop into a branch of PC World in Bristol for repair, where child abuse imagery was found by staff, who informed the police and Glitter was subsequently charged and found guilty of possessing child pornography. This conviction severely damaged Glitter's reputation, and effectively ended his career. In January 2006, after numerous complaints, PC World was forced to remove an advert, that gave misinformation about wireless networking. There have also been countless other complaints over adverts, particularly regarding goods advertised, but not actually available in the shops.

Some PDAs can synchronize some or all of their data using their wireless networking capabilities, rather than having to be directly connected to a personal computer via a cable. Devices running Palm's webOS or Google's Android operating system primarily sync with the cloud. For example, if Gmail is used, information in contacts, email, and calendar can be synchronized between the PDA and Google's servers. RIM sells BlackBerry Enterprise Server to corporations so that corporate BlackBerry users can wirelessly synchronize their PDAs with the company's Microsoft Exchange Server, IBM Lotus Domino, or Novell GroupWise servers.

Although they are emitted and absorbed by short antennas, they are also absorbed by polar molecules, coupling to vibrational and rotational modes, resulting in bulk heating. Unlike higher frequency waves such as infrared and light which are absorbed mainly at surfaces, microwaves can penetrate into materials and deposit their energy below the surface. This effect is used to heat food in microwave ovens, and for industrial heating and medical diathermy. Microwaves are the main wavelengths used in radar, and are used for satellite communication, and wireless networking technologies such as Wi-Fi.

The mechanism of its creation is tribocharging of the adhesive tape and subsequent discharge; this was hypothesized to involve bremsstrahlung with absorption or energy density focusing during dielectric breakdown of a gas. In 2013 researchers at Georgia Institute of Technology's Broadband Wireless Networking Laboratory and the Polytechnic University of Catalonia developed a method to create a graphene antenna: an antenna that would be shaped into graphene strips from 10 to 100 nanometers wide and one micrometer long. Such an antenna could be used to emit radio waves in the terahertz frequency range.

For smart home wireless networking, there are numerous technologies competing to become the standard of choice. Wi-Fi consumes a lot of power, and Bluetooth is limited in signal range and number of devices. Other network standards competing with Z-Wave include Wi-Fi HaLow, Bluetooth 5, Insteon, Thread and ZigBee. Z-Wave has a long open-air operating range at 90 meter (outdoor) and 24+ meter(indoor). Insteon can theoretically address a large number of devices at 17.7 million (compared to ZigBee's 65,000 and Z-Wave's 232).

Pre-programmed frequency agility also forms the basis of some military radio encryption and stealth techniques. Extreme frequency agility lies at the heart of spread spectrum techniques that have gained mainstream acceptance in computer wireless networking such as Wi-Fi. There are disadvantages to digital synthesis such as the inability of a digital synthesiser to tune smoothly through all frequencies, but with the channelisation of many radio bands, this can also be seen as an advantage in that it prevents radios from operating in between two recognised channels. Digital frequency synthesis relies on stable crystal controlled reference frequency sources.

802.11 wireless networking uses the same range of MAC addresses as wired Ethernet to map IP multicast addresses. However, an 802.11 wireless network handles multicast traffic differently, depending on the configuration of delivery traffic indication message (DTIM), and beacon interval settings. If no stations within the basic service set are in power save mode, multicast packets are sent immediately when they arrive. If there are one or more stations in power save mode, access points then only deliver multicast traffic after each DTIM interval and transmit at one of the supported rates in the basic rate set.

Nevertheless, as the model features four USB 2.0 ports, wireless networking and flash memory card support can already be obtained through the use of widely available external USB adapters and third-party PS3-specific media hubs. It was rumored that the Cell processors in the third- generation PS3s (40 GB, 2008 80 GB (CECHL,CECHM,CECHK) and 160 GB) would move from a 90 nm process to the newer 65 nm process, which SCEI CEO Kaz Hirai later confirmed, and later to 45 nm. This change lowers the power consumption of the console and makes it less expensive to produce.

The United States and Canada have several frequency ranges for wireless intercom systems and other wireless products. They are 49 MHz, FM band (160–270 kHz), 900 MHz, 2.4 GHz, 5.8 GHz, and MURS (150 MHz). The frequency that will work best for an application depends on the wireless devices already in use not only in the building itself, but also in surrounding buildings. For instance, if a residence is using wireless networking which operates in the 2.4 GHz range, a wireless intercom that operates in this range may interfere with the network and vice versa.

Panel antennas are common at Ultra high frequency (UHF) frequencies, where they are often used for cellular/mobile base stations or wireless networking due to their size and directional properties. At VHF frequencies, such an antenna would be impractically large for most receiving applications unless implemented as no more than a two-bay design. Some full- power radio stations do use multiple panel antenna bays, installed one above the other on the side of a tall antenna tower, to provide a directional transmitter pattern on these frequencies. The panel antenna is not practical at HF or lower frequencies due to its mechanical size.

The transmission media (often referred to in the literature as the physical media) used to link devices to form a computer network include electrical cables (Ethernet, HomePNA, power line communication, G.hn), optical fiber (fiber-optic communication), and radio waves (wireless networking). In the OSI model, these are defined at layers 1 and 2 — the physical layer and the data link layer. A widely adopted family of transmission media used in local area network (LAN) technology is collectively known as Ethernet. The media and protocol standards that enable communication between networked devices over Ethernet are defined by IEEE 802.3.

NanoRK takes advantage of priority-based preemptive scheduling to help honor the real-time factor of being deterministic thus ensuring task timeliness and synchronization. Due to the characteristic of limited battery power on the wireless node, Nano-RK provides CPU, network, and sensor efficiency through the use of virtual energy reservations, labeling this system as a resource kernel. These energy reservations can enforce energy and communication budgets to minimize the negative impact on the node’s operational lifetime from unintentional errors or malicious behavior by other nodes within the network. It supports packet forwarding, routing and other network scheduling protocols with the help of a light-weight wireless networking stack.

In the field of control theory, for example, it aided in the further development of servomechanism design and control, a crucial component of modern robotics. The development of Wireless Data Communications theory by Bode led to later inventions such as mobile phones and wireless networking. The reason for the new project was that Director T-10 encountered difficulties in calculating the target velocity by differentiating the target position. Due to discontinuities, variations and noise in the radar signal, the position derivatives sometimes fluctuated wildly and this caused erratic motion in the servomechanisms of the gun because their control signal was based on the value of the derivatives.

The Compaq Presario R3000 Line is a Series of laptops designed and built by Hewlett-Packard Corporation. They originally shipped with Microsoft Windows XP but could be configured with 98, 2000, or ME. The series used Intel or AMD Processors, could be ordered with 128 MB (128 MiB) up to 1 GB of RAM (with some being reserved for graphical memory), and could come with an ATI Mobility Radeon 9000/9100 or Nvidia GeForce 4 integrated graphics chip. The integrated sound card was made by Analog Devices and outputs to JBL Pro speakers that sit above the keyboard. Certain configurations included an integrated Broadcom 54G wireless networking card.

Wireless Zero Configuration (WZC), also known as Wireless Auto Configuration, or WLAN AutoConfig, is a wireless connection management utility included with Microsoft Windows XP and later operating systems as a service that dynamically selects a wireless network to connect to based on a user's preferences and various default settings. Article on problems with WZC connecting to unwanted APs, etc., and workarounds This can be used instead of, or in the absence of, a wireless network utility from the manufacturer of a computer's wireless networking device. The drivers for the wireless adapter query the NDIS Object IDs and pass the available network names (SSIDs) to the service.

The technology defined by the Zigbee specification is intended to be simpler and less expensive than other wireless personal area networks (WPANs), such as Bluetooth or more general wireless networking such as Wi-Fi. Applications include wireless light switches, home energy monitors, traffic management systems, and other consumer and industrial equipment that requires short-range low-rate wireless data transfer. Its low power consumption limits transmission distances to 10–100 meters line-of-sight, depending on power output and environmental characteristics. Zigbee devices can transmit data over long distances by passing data through a mesh network of intermediate devices to reach more distant ones.

When computer hardware vendors provide complete technical documentation for their products, operating system developers are able to write hardware device drivers to be included in the operating system kernels. However, some vendors, such as Nvidia, do not provide complete documentation for some of their products and instead provide binary-only drivers. This practice is most common for accelerated graphics drivers, wireless networking devices, and hardware RAID controllers. Most notably, binary blobs are very uncommon for non-wireless network interface controllers, which can almost always be configured via standard utilities (like ifconfig) out of the box; Theo de Raadt of OpenBSD attributes this to the work done by a single FreeBSD developer.

Earth's atmosphere is mainly transparent to radio waves, except for layers of charged particles in the ionosphere which can reflect certain frequencies. Radio waves are extremely widely used to transmit information across distances in radio communication systems such as radio broadcasting, television, two way radios, mobile phones, communication satellites, and wireless networking. In a radio communication system, a radio frequency current is modulated with an information-bearing signal in a transmitter by varying either the amplitude, frequency or phase, and applied to an antenna. The radio waves carry the information across space to a receiver, where they are received by an antenna and the information extracted by demodulation in the receiver.

In 1995, Abidi used CMOS switched-capacitor technology to demonstrate the first direct-conversion transceivers for digital communications. In the late 1990s, RF CMOS technology was widely adopted in wireless networking, as mobile phones began entering widespread use. This changed the way in which RF circuits were designed, leading to the replacement of discrete bipolar transistors with CMOS integrated circuits in radio transceivers. There was a rapid growth of the telecommunications industry towards the end of the 20th century, primarily due to the introduction of digital signal processing in wireless communications, driven by the development of low-cost, very large-scale integration (VLSI) RF CMOS technology.

The baseband processors and radio transceivers in all modern wireless networking devices and mobile phones are mass-produced using RF CMOS devices. RF CMOS circuits are widely used to transmit and receive wireless signals, in a variety of applications, such as satellite technology (including GPS and GPS receivers), Bluetooth, Wi-Fi, near-field communication (NFC), mobile networks (such as 3G and 4G), terrestrial broadcast, and automotive radar applications, among other uses. Examples of commercial RF CMOS chips include Intel's DECT cordless phone, and 802.11 (Wi-Fi) chips created by Atheros and other companies. Commercial RF CMOS products are also used for Bluetooth and Wireless LAN (WLAN) networks.

Google, with its updated version of Chromebook Pixel, shows a similar transition trend towards USB-C, although keeping older USB Type-A ports for a better compatibility with older devices. Although being common until the end of the 2000s decade, Ethernet network port are rarely found on modern laptops, due to widespread use of wireless networking, such as Wi-Fi. Legacy ports such as a PS/2 keyboard/mouse port, serial port, parallel port, or FireWire are provided on some models, but they are increasingly rare. On Apple's systems, and on a handful of other laptops, there are also Thunderbolt ports, but Thunderbolt 3 uses USB-C.

After Mitnick, Markoff continued to write about technology, focusing at times on wireless networking, writing early stories about non-line-of-sight broadband wireless, phased-array antennas, and multiple-in, multiple-out (MIMO) antenna systems to enhance Wi-Fi. He covered Jim Gillogly's 1999 break of the first three sections of the CIA's Kryptos cipher , and writes regularly about semiconductors and supercomputers as well. He wrote the first two articles describing Admiral John Poindexter's return to government and the creation of the Total Information Awareness project. He shared the 2005 Gerald Loeb Award in the Deadline Writing category for the story "End of an Era".

The Berkeley Software Distribution UNIX operating systems (e.g., NetBSD, OpenBSD, and FreeBSD) continue active development of ifconfig and extension of its functionality to cover the configuration of wireless networking interfaces, VLAN trunking, controlling hardware features such as TSO or hardware checksumming or setting up bridge and tunnel interfaces. Solaris has historically used ifconfig for all network interface configuration, but as of Solaris 10 introduced dladm to perform data-link (OSI model layer 2) configuration, reducing ifconfig's purview to IP configuration. In older Linux distributions, ifconfig, in conjunction with the utility route, was used to connect a computer to a network, and to define routes between networks.

Anyone within the geographical network range of an open, unencrypted wireless network can "sniff", or capture and record, the traffic, gain unauthorized access to internal network resources as well as to the internet, and then use the information and resources to perform disruptive or illegal acts. Such security breaches have become important concerns for both enterprise and home networks. If router security is not activated or if the owner deactivates it for convenience, it creates a free hotspot. Since most 21st-century laptop PCs have wireless networking built in (see Intel "Centrino" technology), they don't need a third-party adapter such as a PCMCIA Card or USB dongle.

Each standard varies in geographical range, thus making one standard more ideal than the next depending on what it is one is trying to accomplish with a wireless network. The performance of wireless networks satisfies a variety of applications such as voice and video. The use of this technology also gives room for expansions, such as from 2G to 3G and, 4G and 5G technologies, which stand for the fourth and fifth generation of cell phone mobile communications standards. As wireless networking has become commonplace, sophistication increases through configuration of network hardware and software, and greater capacity to send and receive larger amounts of data, faster, is achieved.

Apple Offers iMac's Laptop Offspring, the iBook, The New York Times, July 22, 1999STATE OF THE ART; Not Born To Be Wired, The New York Times, November 25, 1999 The iBook had three different designs during its lifetime. The first, known as the "Clamshell", was inspired by the design of Apple's popular iMac line at the time. It was a significant departure from previous portable computer designs due to its shape, bright colors, incorporation of a handle into the casing, lack of a display closing latch, lack of a hinged cover over the external ports and built-in wireless networking. Two years later, the second generation abandoned the original form factor in favor of a more conventional, rectangular design.

The Blu-ray/HD DVD conflict resembled the earlier videotape format war between VHS and Betamax, partly because of Sony's strong involvement in both episodes. These format wars have often proved destructive to both camps because consumers, afraid of committing to a losing standard, would refrain from purchasing either. Format wars have been avoided in notable cases such as the DVD Forum for the unified DVD standard (except for a minor war from 1998 to 1999 with the DIVX format), the Grand Alliance for the HDTV standard, and the Wi-Fi Alliance for wireless networking standards. The emergence of high definition players followed the entry of HDTV televisions into the mainstream market in the mid-2000s.

In addition, all Newton devices have infrared connectivity, initially only the Sharp ASK protocol, but later also IrDA, though the Sharp ASK protocol was kept in for compatibility reasons. Unlike the Palm Pilot, all Newton devices are equipped with a standard PC Card expansion slot (two on the 2000/2100). This allows native modem and even Ethernet connectivity; Newton users have also written drivers for 802.11b wireless networking cards and ATA-type flash memory cards (including the popular CompactFlash format), as well as for Bluetooth cards. Newton can also dial a phone number through the built-in speaker of the Newton device by simply holding a telephone handset up to the speaker and transmitting the appropriate tones.

PPSSPP supports save states, dynamic recompilation (JIT) and has rudimentary support of ad hoc wireless networking. To decode PSP multimedia data PPSSPP uses the FFmpeg software library, which was enhanced to enable it to handle Sony's proprietary ATRAC3plus audio format as used by the PSP. PPSSPP offers graphical features that are enhancements over the PSP's capabilities, such as higher screen resolutions, antialiasing, image scaling, support for shaders, and linear and anisotropic filtering. The ports of PPSSPP for mobile devices offer additional features specific to each platform, such as 'immersive mode' for Android devices, support of the multimedia buttons within Symbian devices and screen stretching on BlackBerry 10 devices to support square screens.

It retailed for US$49 at the time of its introduction. Apart from using the Apple USB Modem for Internet dial-up and faxing, it is also being suggested as a low cost line interface (aka FXO interface) for telephony applications, such as for telephone systems (software PBX) and answering machine software. The decision to drop the built-in dial-up modem is reminiscent of Apple's decision to drop built-in floppy drives. With the rise of broadband Internet and the general availability of wireless networking, it is likely that Apple felt that it was of more use for people to have broadband using an ethernet cable or a wireless system instead of dial-up.

The Transmission Control Protocol uses a variant of Go-Back-N ARQ to ensure reliable transmission of data over the Internet Protocol, which does not provide guaranteed delivery of packets; with Selective Acknowledgement (SACK), it uses Selective Repeat ARQ. IEEE 802.11 wireless networking uses ARQ retransmissions at the data-link layer. The ITU-T G.hn standard, which provides a way to create a high-speed (up to 1 Gbit/s) local area network using existing residential wiring (power lines, telephone lines (ADSL), and coaxial cables), uses Selective Repeat ARQ to ensure reliable transmission over noisy media. ARQ systems were widely used on shortwave radio to ensure reliable delivery of data such as for telegrams.

It enabled sophisticated, low- cost and portable end-user terminals, and gave rise to small, low-cost, low- power and portable units for a wide range of wireless communication systems. This enabled "anytime, anywhere" communication and helped bring about the wireless revolution, leading to the rapid growth of the wireless industry. The baseband processors and radio transceivers in all modern wireless networking devices and mobile phones are mass-produced using RF CMOS devices.

Networking devices includes a broad range of equipment which can be classified as core network components which interconnect other network components, hybrid components which can be found in the core or border of a network and hardware or software components which typically sit on the connection point of different networks. The most common kind of networking hardware today is a copper-based Ethernet adapter which is a standard inclusion on most modern computer systems. Wireless networking has become increasingly popular, especially for portable and handheld devices. Other networking hardware used in computers includes data center equipment (such as file servers, database servers and storage areas), network services (such as DNS, DHCP, email, etc.) as well as devices which assure content delivery.

As of Ubuntu Studio 12.04, the default kernel is linux-lowlatency, which in essence is a generic Ubuntu Linux kernel, with a tweaked configuration to allow for stable operation for audio applications at lower latencies. Since much of the real-time patch has now been implemented into the vanilla kernel, and considering the difficulties in maintaining linux-rt, Ubuntu Studio decided on using linux-lowlatency in its place. The scheduler allows applications to request immediate CPU time, which can drastically reduce audio latency. In 9.10, the "Ubuntu Studio Controls" provided under System>Administration permit the user to "Enable Nice", allowing the use of wireless networking and proprietary graphics cards drivers while maintaining low audio latency free of XRUNs (audio drop-outs) in JACK.

If there are large differences between the "cost" of each data flow, which is the case especially in wireless networking, resources may be assigned to only one or very few data flows per physical channel in the network. If there are many simultaneously active data flows, a majority of the data flows will have to wait until the most inexpensive flows have no more data to transfer, and will suffer from scheduling starvation. A maximum throughput scheduling policy may be tempting since it would optimize the resource utilization in a given network, but it would not be likely to maximize profit for the network operator. The levels of customer satisfaction would remain low due to many customers experiencing long or permanent service outages.

Project 28 is the name given to a U.S. border protection program that runs along a stretch of the US/Mexican border in southern Arizona.Randal C. Archibold, "28-Mile Virtual Fence Is Rising Along the Border", New York Times, June 26, 2007 The project, the first phase of a much larger program called the "Secure Border Initiative network" (SBInet), was scheduled to be completed in mid-2007, but did not become operational until late 2007. It involves the placement of 9 high-tech surveillance towers that monitor activity using radar, high-resolution cameras, and wireless networking, looking for incursions to report to the Border Patrol. In February 2008, authorities said that the project did not work as planned nor did it meet the needs of the U.S. Border Patrol.

The model introduced in June 2012 includes two Ethernet ports: one WAN and one LAN. The original version (M9470LL/A, model A1084) was introduced by Apple on 7 July 2004, and included an analog–optical audio mini-jack output, a USB port for remote printing or charging the iPod (iPod shuffle only), and one Ethernet port. The main processor of the 802.11g AirPort Express was a Broadcom BCM4712KFB wireless networking chipset, which incorporated a 200 MHz MIPS processor. The audio was handled by a Texas Instruments Burr-Brown PCM2705 16-bit digital-to-analog converter. An updated version (MB321LL/A, model A1264) supporting the faster 802.11 Draft-N draft specification and operation in either of the 2.4 GHz and 5 GHz bands, with almost all other features identical, was introduced by Apple in March 2008.

They may desire to share their Internet access with their neighbours or the general public or may be intimidated by the knowledge and effort required to secure their network while making it available to their own laptops. Some wireless networking devices may not support the latest security mechanisms, and users must therefore leave their network unsecured. For example, the Nintendo DS and Nintendo DS Lite can only access wireless routers using the discredited WEP standard, however, the Nintendo DSi and Nintendo 3DS both support WPA encryption. Given the rarity of such cases where hosts have been held liable for the activities of piggybackers, they may be unaware or unconcerned about the risks they incur by not securing their network, or of a need for an option to protect their network.

SuperWiFi is being used to reference standard based 802.11g/n/ac/ax implementations over unlicensed 2.4 and 5 GHz WiFi channels but with performance enhancements for antenna control, multiple path beam selection, advance control for best path, and applied intelligence for load balancing. In North America, Krysp Wireless has introduced and deployed multiple products supporting SuperWiFi for carrier deployments and expansive, outdoor enterprise use cases. Super Wi-Fi is a term originally coined by the United States Federal Communications Commission (FCC) to describe a wireless networking proposal which the FCC plans to use for the creation of longer-distance wireless Internet access. The use of the trademark "Wi-Fi" in the name has been criticized because it is not based on Wi-Fi technology or endorsed by the Wi-Fi Alliance.

Built-in wireless networking might be enabled by default, without the owner realizing it, thus broadcasting the laptop's accessibility to any computer nearby. Modern operating systems such as Linux, macOS, or Microsoft Windows make it fairly easy to set up a PC as a wireless LAN "base station" using Internet Connection Sharing, thus allowing all the PCs in the home to access the Internet through the "base" PC. However, lack of knowledge among users about the security issues inherent in setting up such systems often may allow others nearby access to the connection. Such "piggybacking" is usually achieved without the wireless network operator's knowledge; it may even be without the knowledge of the intruding user if their computer automatically selects a nearby unsecured wireless network to use as an access point.

Intel's Communication Streaming Architecture (CSA) was a mechanism used in the Intel Hub Architecture to increase the bandwidth available between a network card and the CPU. It consists of connecting directly the network controller to the Memory Controller Hub (northbridge), instead of to the I/O Controller Hub (southbridge) through the PCI bus, which was the common practice until that point. The technology was only used in Intel chipsets released in 2003, and was largely seen as a stop-gap measure to allow Gigabit Ethernet chips to run at full-speed until the arrival of a faster expansion bus (it was also used to connect the Wireless networking chips in Intel's Centrino mobile platform). To Intel's credit though, CSA-connected Ethernet chips did show consistently higher transfer rates than comparable PCI cards.

Users of wireless networking devices are typically exposed for much longer periods than for mobile phones and the strength of wireless devices is not significantly less. Whereas a Universal Mobile Telecommunications System (UMTS) phone can range from 21 dBm (125 mW) for Power Class 4 to 33 dBm (2W) for Power class 1, a wireless router can range from a typical 15 dBm (30 mW) strength to 27 dBm (500 mW) on the high end. However, wireless routers are typically located significantly farther away from users' heads than a phone the user is handling, resulting in far less exposure overall. The Health Protection Agency (HPA) says that if a person spends one year in a location with a WiFi hot spot, they will receive the same dose of radio waves as if they had made a 20-minute call on a mobile phone.

They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by a radio receiver connected to another antenna. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking and satellite communication among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft and missiles, a beam of radio waves emitted by a radar transmitter reflects off the target object, and the reflected waves reveal the object's location.

Initially called Shared Wireless Access Protocol (SWAP) and later just HomeRF, this open specification allowed PCs, peripherals, cordless phones and other consumer devices to share and communicate voice and data in and around the home without the complication and expense of running new wires. HomeRF combined several wireless technologies in the 2.4 GHz ISM band, including IEEE 802.11 FH (the frequency-hopping version of wireless data networking) and DECT (the most prevalent digital cordless telephony standard in the world) to meet the unique home networking requirements for security, quality of service (QoS) and interference immunity—issues that still plagued Wi-Fi (802.11b and g). HomeRF used frequency hopping spread spectrum (FHSS) in the 2.4 GHz frequency band and in theory could achieve a maximum of 10 Mbit/s throughput; its nodes could travel within a 50-meter range of a wireless access point while remaining connected to the personal area network (PAN). Several standards and working groups focused on wireless networking technology in radio frequency (RF).

The need for a TATRC- like organization was recognized as early as 1990, when the Army and Air Force medical departments wanted to jointly develop, procure, and deploy a filmless medical diagnostic imaging system (MDIS), at a time when such a system did not exist. On 1 November 1991, Lieutenant Colonel Fred Goeringer was assigned as the MDIS project officer, and by 1993 under his leadership the Navy had also joined this effort and a formal organization, the Medical Advanced Technology Management Office (MATMO) was established. MATMO, as it was referred to, became better known as the DOD “Telemedicine Test Bed” after the Assistant Secretary of Defense for Health Affairs designated the Army as Executive Agent for telemedicine in 1994. During the mid-1990s a broad array of advanced and developing technologies were used to meet military medicine requirements including biomedical science, a secure global positioning system, wireless networking, data compression, and adaptable tactical and mobile networks.

The first consoles could only play a set group of games built into the hardware. Swappable ROM cartridges were introduced with the Fairchild Channel F in 1976. Handheld consoles emerged from technology improvements in handheld electronic games as these shifted from mechanical to electronic/digital logic, and away from light-emitting diode (LED) indicators to liquid-crystal displays (LCD) that resembled video screens more closely, with the Microvision in 1979 and Game & Watch in 1980 being early examples, and fully realized by the Game Boy in 1989. Since the 1970s, both home and handheld consoles became more advanced following global changes in technology, including improved electronic and computer chip manufacturing to increase computational power at lower costs and size, the introduction of 3D graphics and hardware-based graphic processors for real- time rendering, digital communications such as the Internet, wireless networking and Bluetooth, and larger and denser media formats as well as digital distribution.

The DS's lower screen is touch sensitive, designed to be pressed with a stylus, a user's finger or a special "thumb pad" (a small plastic pad attached to the console's wrist strap, which can be affixed to the thumb to simulate an analog stick). More traditional controls include four face buttons, two shoulder buttons, a D-pad, and "Start" and "Select" buttons. The console also features online capabilities via the Nintendo Wi-Fi Connection and ad-hoc wireless networking for multiplayer games with up to sixteen players. It is backwards-compatible with all Game Boy Advance games, but not games designed for the Game Boy or Game Boy Color. On January 2006, Nintendo revealed an updated version of the DS: the Nintendo DS Lite (released on March 2, 2006, in Japan) with an updated, smaller form factor (42% smaller and 21% lighter than the original Nintendo DS), a cleaner design, longer battery life, and brighter, higher- quality displays, with adjustable brightness.

The wireless networking has much greater range than typical consumer laptops. The XO-1 has also been designed to be lower cost and much longer-lived than typical laptops. In 2009, OLPC announced an updated XO (dubbed XO-1.5) that takes advantage of the latest component technologies. The XO-1.5 includes a new VIA C7-M processor and a new chipset providing a 3D graphics engine and an HD video decoder. It has 1GB of RAM and built-in storage of 4 GB, with an option for 8 GB. The XO-1.5 uses the same display, and a network wireless interface with half the power dissipation. Early prototype versions of the hardware were available in June 2009, and they are available for software development and testing available for free through a developer's program. An XO-1.75 model was developed that used a Marvell ARM processor, targeting a price below $150 and date in 2011. XO-3 production model The XO-2 two sheet design concept was canceled in favor of the one sheet XO-3.

Other important research results in his career include design and prototyping one of the earliest VSAT (very small aperture terminal) data networks during the 1980s. This technology enabled the first generation of data networks in the US and is still used to provide Internet access to remote areas all over the world. In the early 1990s he was a co-lead for a multi-company research team which designed one of the first HDTV systems tested by the FCC in 1991, significantly influencing the “ATSC” digital TV standard in wide use today. After joining Rutgers as a Professor, Dr. Raychaudhuri collaborated with Ivan Seskar (Chief Technologist at WINLAB) to build the "ORBIT radio grid testbed" the world's largest open research testbed for evaluation of future wireless networking protocols. During the period 2010-18, his group at WINLAB has also developed a novel clean-slate mobility-centric future Internet architecture called “MobilityFirst”, which proposes a new “named object” approach to Internet routing based on the use of globally unique identifiers (GUIDs) in place of conventional IP addresses.
