   Able to produce a reasonable call with lower signal (cell phone reception) levels. Uses soft handoff, reducing the likelihood of dropped calls. IS-95's variable rate voice coders reduce the rate being transmitted when speaker is not talking, which allows the channel to be packed more efficiently. Has a well-defined path to higher data rates.

   For very low-power systems, such as mobile phones, signal strength is usually expressed in dB - microvolts per metre (dBμV/m) or in decibels above a reference level of one milliwatt (dBm). In broadcasting terminology, 1 mV/m is 1000 μV/m or 60 dBμ (often written dBu). Examples. 100 dBμ or 100 mV/m: blanketing interference may occur on some ...

   There are 51 MTAs, 493 BTAs and 175 EAs in the United States. The Advanced Wireless Services (AWS) bands, auctioned in the summer of 2006, were for 1,710–1,755 MHz, and 2,110–2,155 MHz. The spectrum was divided into blocks: A blocks were for Cellular Market Areas, based on existing cellular (1G) licenses, and were 2 × 10 MHz.

7. Cellular network - Wikipedia

   en.wikipedia.org/wiki/Cellular_network

   A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (such as a base station). These base stations provide the cell with the network coverage which can be used for ...
