Analog cellular systems became widespread in Europe in years after the assassination of John F Kennedy and the Vietnam War In 1967 Nippon Telegraph & Telephone company, the Japanese equivalent of AT&T, proposed a nationwide cellular system at 800 MHz in Japan In January 1969 the year Neil Armstrong landed on the moon the Bell System made commercial cellular radio operational by employing frequency reuse for the first time on trains Delighted Metroliner passengers could make cellular calls from payphones while traveling between New York City and Washington, DC By 1971, the Bell System in the US had submitted to the FCC a cellular radio plan for full-scale commercial service to consumers, but six more years would pass before the FCC allowed AT&T to start a trial A few years later, on October 17, 1973, Dr Martin Cooper of Motorola filed a patent entitled radiotelephone system," which outlined Motorola s first ideas for cellular radio Cooper set up a base station in New York with the first working prototype of a cellular telephone and called over to his rivals at Bell Labs in New Jersey Both Bell Labs and Motorola were fiercely competitive in the 1960s and early 70s, trying to make cellular communications technology practical (it was not until 1977 that the FCC approved AT&T s request to operate a cellular system) And despite incredible demand, it took 30 years for cellular to go commercial in the United States from the mobile telephone system s first introduction The delay came, in part, through bureaucratic bungling, but radio common carriers, which provided conventional wireless phone service in competition with AT&T, also played a part Carriers like American Radio Telephone Service, and suppliers to them like Motorola, which catered to the radio communications needs of companies ranging from taxicabs to marine and naval ship-to-shore, feared the Bell system would dominate cellular radio if private companies weren t allowed to compete equally The radio carriers fought for equal access in court and wanted the FCC to ensure an open market At America s Bicentennial, 1976, only 44,000 Bell subscribers had AT&T mobile telephone systems, and an additional 20,000 people sat on five to ten year waiting lists Radio common carriers had roughly 80,000 units deployed in the American market Spectrum was a primary deterrent As late as 1978 the Bell System, independent carriers, and non-wireline carriers divided just 54 channels nationwide for wireless; and this compares to 666 channels that the first analog

cellular systems would require for operation Most telcos gave scant attention to mobile services, focusing instead on delivering basic telephone service to the masses The 1980s at last saw the deployment of primary analog cellular technology for voice, Advanced Mobile Phone Service (AMPS) operating in North America at 800 MHz Worldwide commercial AMPS deployment followed quickly, and several competing standards for digital voice and data ultimately emerged (see Figure 21) It s interesting to note that virtually all new and disruptive communications technologies have chequered histories marked by regulatory battles and long delays in adoption Facsimile, for example, was developed in Bell Labs in the 1920 s, but commercial fax was not launched until the 1960s, and mainstream use came to be in the 1980s Wireless has followed a similar path: at first inventions took decades to become commercial realities; but now the turn-around time for commercialization can be a matter of months

The true wireless revolution for voice and data did not begin until the advent of low-cost microprocessors and digital switching (1980s - present day) Ironically, the North American Bell System, while building the finest landline telephony system in the world, never seemed truly committed to mobile voice, much less mobile data, until the mid 1990s In addition, federal regulations hindered development of wireless services by tightly regulating spectrum By contrast, in Europe and Japan, where governments regulated their state-run telephone companies but permitted rapid building of wireless networks, both analog and digital mobile telephony came in sooner and less expensively, making the networks attractive to millions of subscribers Wireless messaging grew fast in the paging world, where the British Post Office had invented POCSAG, a paging standard to support very short messages on the original numeric pagers at slow speeds (512 bps to 2400 bps) Motorola came out with a competitive, faster network infrastructure for paging called FLEX (oneway paging, a synchronous protocol designed in 1993), which became virtually ubiquitous FLEX paging networks offer five times the network capacity as POCSAG, support longer messages, and are supported in 30 countries and by most paging carriers in the US By 1997 Motorola had released its more powerful REFLEX
