The policy of liberalisation that was embarked by Prime Minister P. V. Narasimha Rao in the 1990s helped the Indian Telecom sector to grow rapidly. The government gradually allowed the entry of the private sectors into telecom equipment manufacturing, value added services, radio paging and cellular mobile services. In 1994, the government formed the National Telecom Policy (NTP) which helped to attract Foreign Direct Investments (FDI) and domestic investments. The entry of private and international players resulted in need of independent regulatory body.

Further sub-sets of some of these internationally defined services are often created at the national level. For example, within the land mobile service, a country may choose to define such services as paging, dispatch two-way radio service, cellular mobile telephone service, trunked mobile radio service, etc. Many of these definitions are based upon the nature of the service being provided rather than the international concept of a radiocommunication service. In other words, the term “service” can be used in these two different ways.

In the early 1990s, amateur radio experimenters began to use personal computers with audio cards to process radio signals. In the 1990s, the wireless revolution began, with the advent of digital wireless networks. It began with the introduction of digital cellular mobile networks, enabled by LDMOS (power MOSFET) RF power amplifiers and CMOS RF circuits. In 1994, the U.S. Army and DARPA launched an aggressive, successful project to construct a software- defined radio that can be programmed to be virtually any radio by changing its software program.

The term Cellular is sometimes used to describe GSM services in the 850 MHz band, because the original analog cellular mobile communication system was allocated in this spectrum. Further GSM-850 is also sometimes called GSM-800 because this frequency range was known as the "800 MHz band" (for simplification) when it was first allocated for AMPS in the United States in 1983. In North America GSM-1900 is also referred to as Personal Communications Service (PCS) like any other cellular system operating on the "1900 MHz band".

Edholm's law, proposed by and named after Phil Edholm in 2004, holds that the bandwidth of telecommunication networks double every 18 months, which has proven to be true since the 1970s. The trend is evident in the cases of Internet, cellular (mobile), wireless LAN and wireless personal area networks. The MOSFET (metal-oxide-semiconductor field-effect transistor) is the most important factor enabling the rapid increase in bandwidth. The MOSFET (MOS transistor) was invented by Mohamed M. Atalla and Dawon Kahng at Bell Labs in 1959, and went on to become the basic building block of modern telecommunications technology.

Porter was an engineer at Bell Laboratories during the years of transition from radio telephones to modern cellular mobile communications. Porter was the Bell Labs engineer who proposed that cell towers be at the corners of the hexagon cells rather than the centers and have directional antennas that would transmit/receive in 3 directions into 3 adjacent hexagon cells. In Porter's design, the cell sites can flexibly assign channels to handheld phones based on signal strength, allowing the same frequency to be re-used in various locations without interference. This allowed a larger number of phones to be supported over a geographical area.

Higher frequencies (especially above 200 MHz) are almost exclusively line-of-sight. These services are different from cellular mobile telephone systems in that no infrastructure (towers, base stations) is required; communications is point- to-point directly between users. However, this also means that communication range is usually limited to line-of-sight propagation, a few kilometres (miles) under the best of circumstances, and much less in heavily built up urban areas. Also unlike mobile telephones, operation is push-to-talk; a user must wait for the shared frequency to be clear before transmitting, and all stations on the frequency may hear the transmission.

It provides coverage in areas where it does not own radio frequency spectrum licenses via roaming agreements with other operators of compatible networks. In addition to its cellular mobile network, T-Mobile US operates a nationwide Wi-Fi Internet- access network under the T-Mobile HotSpots brand. The T-Mobile HotSpot service offers access to a nationwide network of approximately 8,350 access points, installed in venues such as Starbucks coffeehouses, FedEx Office Office and Print Centers, Hyatt hotels and resorts, Red Roof Inns, Sofitel hotels, Novotel hotels, the airline clubs of American Airlines, Delta Air Lines, United Airlines and US Airways, and airports.

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.

In analogy to the improvements in the speed and capacity of digital computers, provided by advances in semiconductor technology and expressed in the bi-yearly doubling of transistor density, which is estimated by Moore's law, the capacity and speed of telecommunications networks has followed similar advances, for similar reasons. In telecommunication, this is expressed in Edholm's law, proposed by and named after Phil Edholm in 2004. This empirical law holds that the bandwidth of telecommunication networks doubles every 18 months, which has proven to be true since the 1970s. The trend is evident in the Internet, cellular (mobile), wireless local area networks (LANs), and personal area networks.

Such calls are classified as failed call attempts. In many practical cases this definition needs to be further expanded with a number of detailed specifications describing which calls exactly are counted as successfully set up and which not. This is determined to a great degree by the stage of the call setup procedure at which a call is counted as connected. In modern telecommunication systems, such as cellular (mobile) networks, the call setup procedure maybe very complex and the point at which a call is considered successfully connected may be defined in a number of ways, thus influencing the way the call setup success rate is calculated.

The company derives its name from the chemical element iridium which has an atomic number of 77, equalling the initial number of satellites which were planned to be deployed. The founding company went into Chapter 11 bankruptcy nine months later, on August 13, 1999. The handsets could not operate as promoted until the entire constellation of satellites was in place, requiring a massive initial capital cost running into billions of dollars. The cost of service was prohibitive for many users, reception indoors was difficult and the bulkiness and expense of the hand held devices when compared to terrestrial cellular mobile phones discouraged adoption among potential users.

Edholm's law, proposed by and named after Phil Edholm, refers to the observation that the three categories of telecommunication, namely wireless (mobile), nomadic (wireless without mobility) and wired networks (fixed), are in lockstep and gradually converging. Edholm's law also holds that data rates for these telecommunications categories increase on similar exponential curves, with the slower rates trailing the faster ones by a predictable time lag. Edholm's law predicts that the bandwidth and data rates double every 18 months, which has proven to be true since the 1970s. The trend is evident in the cases of Internet, cellular (mobile), wireless LAN and wireless personal area networks.

Along the way, the LocoRoco can grow in size by eating special berries, and then can be split and rejoined to pass the LocoRoco through narrow spaces. The game's bright and colorful visuals and dynamic music soundtrack were hallmarks of the game, earning it several awards from the gaming press in 2006. While the game did not sell high volumes, its success led to the development of four other LocoRoco titles – two sequels for the PSP (PlayStation Portable)/PSP Go, a spin-off for the PlayStation 3 and a mobile version (called LocoRoco Mobile and LocoRoco Hi, depending on the market) for cellular (mobile) telephones. A remastered version of the game was released in 2017 for the PlayStation 4.

The liberalisation of Bangladesh's telecommunications sector began with small steps in 1989 with the issuance of a licence to a private operator for the provision of inter alia cellular mobile services to compete with Bangladesh Telegraph and Telephone Board (BTTB), the previous monopoly provider of telecommunications services within Bangladesh. Significant changes in the number of fixed and mobile services deployed in Bangladesh occurred in the late 1990s and the number of services in operation have subsequently grown exponentially in the past five years. The incentives both from government and public sectors have helped the industry grow and it is now one of the biggest industries in Bangladesh. As a populous country, its huge market has attracted many foreign investors.

In 1947, W. Rae Young proposed what are now called cell phones in a report to the RMA Systems Committee.page 3 of D. H. Ring's report Coworker Douglas H. Ring at Bell Labs, liked Young's idea about locating many mobile phone towers in a hexagonal cellular arrangement throughout each city so that every mobile phone user would be able to communicate from at least one cell through the telephone system. Douglas Ring credited W. Rae Young with suggesting the hexagonal cell layout and expanded on Rae Young's concept in another internal Technical Memo dated 11 December 1947. In 1951 Young was appointed Supervisor of the cellular systems engineering team and later became department head of cellular mobile phone development at Bell Labs.

Due to the vagaries of ionospheric communications, HF radio as used by large governmental organizations in the mid-20th century was traditionally the domain of highly skilled and trained radio operators. One of the new characteristics that embedded microprocessors and computers brought to HF radio via ALE, was alleviation of the need for the radio operator to constantly monitor and change the radio frequency manually to compensate for ionospheric conditions or interference. For the average user of ALE, after learning how to work the basic functions of the HF transceiver, it became similar to operating a cellular mobile phone. For more advanced functions and programming of ALE controllers and networks, it became similar to the use of menu-enabled consumer equipment or the optional features typically encountered in software.

A mobile radio telephone Mobile radio telephone systems were telephone systems of a wireless type that preceded the modern cellular mobile form of telephony technology. Since they were the predecessors of the first generation of cellular telephones, these systems are sometimes retroactively referred to as pre-cellular (or sometimes zero generation, that is, 0G) systems. Technologies used in pre-cellular systems included the Push to Talk (PTT or manual), Mobile Telephone Service (MTS), Improved Mobile Telephone Service (IMTS), and Advanced Mobile Telephone System (AMTS) systems. These early mobile telephone systems can be distinguished from earlier closed radiotelephone systems in that they were available as a commercial service that was part of the public switched telephone network, with their own telephone numbers, rather than part of a closed network such as a police radio or taxi dispatch system.

At the most basic level, Personal Communications Service (PCS) describes a set of communications capabilities which allows some combination of terminal mobility, personal mobility, and service profile management. More specifically, PCS refers to any of several types of wireless voice or wireless data communications systems, typically incorporating digital technology, providing services similar to advanced cellular mobile or paging services. In addition, PCS can also be used to provide other wireless communications services, including services which allow people to place and receive communications while away from their home or office, as well as wireless communications to homes, office buildings and other fixed locations. Described in more commercial terms, PCS is a generation of wireless-phone technology that combines a range of features and services surpassing those available in analog- and digital-cellular phone systems, providing a user with an all-in- one wireless phone, paging, messaging, and data service.

Prior to 1973, cellular mobile device technology was limited to devices installed in cars and other vehicles.See Amos Joel patent 3,663,762. The first fully automated telephone calling system for vehicles was launched in Sweden in 1960, called MTA (mobile telephone system A). Calls from the car were direct dial, whereas incoming calls required an operator to determine which base station the device was currently at. In 1962, an upgraded version called Mobile System B (MTB) was introduced.
