GSM EDGE RF Interface: Modulation, Slot, Burst The 2G GSM EDGE radio interface utilised a different form of modulation to achieve its comparatively high data rates.
As in the case of the GSM, the frequency spacing between each physical channel is 200 kHz. It is also a Time Division Multiple Access (T DMA) system: for each carrier frequency, data transmission is made of periodical TDMA frames. Each frame is divided in 8 time slots (T S) of 577 µs and has a period of 4.615 ms.
