Analog Cellular Sent to Landfill History

    The first generation mobile communication, which faithfully served humanity for almost 30 years, since this Monday has lost its last stronghold. In the United States , the license to support AMPS networks, which were owned by AT&T and Verizon Wireless , was terminated .

    The AMPS (Advanced Mobile Phone System) standard network, first built by Bell in Chicago in 1983, has remained the most popular network in North America for many years. Analog technology, devoid of any encryption of conversations (they could be eavesdropped by a conventional VHF receiver), operating in the interference-filled 800 MHz range, with limited bandwidth, which led to long minutes of connection waiting, it still had a number of obvious advantages. The coverage area of ​​AMPS base stations is much larger than that of their GSM counterparts, which made the connection of this standard especially popular in sparsely populated areas.

    Subsequently, AMPS was supplanted by more modern digital DAMPS, and then GSM. In Europe, the first generation network for many years worked on another standard - NMT (until recently, so beloved by domestic summer residents), but in recent years it has finally lost its frequencies to CDMA2000 networks.
