ECSD (Enhanced Circuit Switched Data)

In Enhanced Data rates for GSM Evolution (EDGE) cel-

lular radio networks, an enhancement of the native Global System for Mobile Communications (GSM) circuit-switching protocol. ECSD adds 8-Phase Shift Keying (8-PSK) as a modulation option, thereby increasing the efficiency of data transmission and yielding greater throughput. See also 8-PSK, EDGE, GSM, modulation, protocol, and throughput.
