Focuses on the mechanism of Global System for Mobile Communications (GSM) and Time Division Multiple Access (TDMA) cellular networks. Frequency sharing in GSM, TDMA and in Digital-American Mobile Phone System (D-AMPS); Data relay in GSM, D-AMPS and other TDMA networks.Dornan...
In TDMA, a guard intervalmust be addedbetween adjacent TDMA slots to reduce interference between transmissions and prevent overlapping transmissions. This short time interval requires extra time and energy, which can be a critical limiting factor for cellular networks operating on limited energy. In TD...
