Enhanced Data rates for GSM Evolution is an advanced digital mobile phone technology which enables enhanced data transmission speeds as a backward-compatibility extension of GSM. What this means to the user is that the old analog signal used to send data at a significant speed was supplemented with the new digital signal for transmission purposes. This has several advantages: first, it allows the end-user to enjoy the benefits of CDMA and TDMA without having to upgrade his/her network connection; second, by eliminating the need for a new phone purchase, it reduces overall phone costs since EDGE provides a higher data transfer rate than both CDMA and TDMA; and third, it provides the option to go ‘wireless’ even if your phone happens to be tied to a wireless network.
