The NADC Communications System

The North American Dual-Mode Cellular (NADC) is one of the cellular
communications systems. NADC is also referred to as North American Digital
Cellular, or American Digital Cellular (ADC). Occasionally, it is also referred to as
Digital Advanced Mobile Phone Service (D-AMPS) or -NADC-TDMA. The
NADC communications system is defined in the Electronics Industry Alliance
(EIA) and Telecommunication Industry Association (TIA) standard documents.
The following is a list of all relevant and applicable standard documents:

The EDGE Standard

What is EDGE with GSM?
The Global System for Mobile communication (GSM) digital communications
standard defines a voice and data over-air interface between a mobile radio and the
system infrastructure. This standard was designed as the basis for a radio
communications system. A base station control center (BSC) is linked to multiple
base transceiver station (BTS) sites which provide the required coverage.
