    2G, or second-generation cellular network technology, marks the transition from analog to digital communication in mobile networks. Defined by the European Telecommunications Standards Institute (ETSI) under the GSM standard, which became the first globally adopted framework for mobile communications, 2G was first commercially launched in 1991 by Radiolinja (now part of Elisa Oyj) in Finland.

    CDMA2000 is a family of 3G mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites. It is a backwards-compatible successor to second-generation cdmaOne (IS-95) set of standards and used especially in North America and South Korea, China, Japan, Australia and New Zealand. It was standardized ...

    IS-54 employs the same 30 kHz channel spacing and frequency bands (824-849 and 869-894 MHz) as AMPS. Capacity was increased over the preceding analog design by dividing each 30 kHz channel pair into three time slots and digitally compressing the voice data, yielding three times the call capacity in a single cell.

    The drawback is that at some point, one cannot talk any louder. After this if the noise still rises (more people join the party/cell) the listener cannot make out what the talker is talking about without coming closer to the talker. In effect, CDMA cell coverage decreases as the number of active users increases. This is called cell breathing.
