In UMTS, Universal Terrestrial Radio Access Network also plays its role as the controller. Both 2G and 3G have different frequency allocations as well.
The modern 2G and 3G networks also extracted different features from GSM networks like Subscriber Identity Module and Universal SIM. In 2G and 3G networks, their uplink and downlinks are different but in GSM networks, downlinks and uplinks were similar. The time multiplexing for transmission is also different in both networks. 3G network with their FDD and TDD use different frequencies for uplink signals.
Telecommunication engineers believe that secure networks give you the facility to share higher rates of data. WCDMA helps make broadband communication a reality. In this method, people have the luxury of video conferencing, high speed internet and mobile streaming.
