Quizplus · Accepted Answer

4G networks do not have a circuit-switched subsystem, which refers to the traditional method of establishing a dedicated communication channel between two devices for the duration of a transmission. Instead, 4G networks use a packet-switched IP system, which breaks data down into packets and sends them through the network to their destination. WiMAX and LTE are both technologies used for 4G networks, and GSM is the technology used for 2G and 3G networks.
