2G networks were the first to offer data services and SMS text messaging, but their data transfer rates are lower than those of their successors. 3G networks succeed 2G ones, offering faster data transfer rates and are the first to enable video calls.
Read moreWhat is 2G 3G network?
3G network combines aspects of the 2G network with new technologies and protocols to deliver a significantly faster data rate . By using packet switching, the original technology was improved to allow speeds up to 14 Mbps. It used Wide Band Wireless Network that increased clarity.
Read moreWhat is LTE architecture?
A standard LTE system architecture consists of an Evolved UMTS Terrestrial Radio Access Network, more commonly known as E-UTRAN, and the System Architecture Evolution, also known as SAE . SAE’s main component is the Evolved Packet Core, also known as an EPC. The E-UTRAN is comprised of: User Equipment (UEs)
Read moreWhat is 4G network architecture?
4 G network is an integration of all heterogeneous wireless access networks such as Ad-hoc, cellular, hotspot and satellite radio component . Technologies used in 4 G are smart antennas for multiple input and multiple output (MIMO), IPv6, VoIP, OFDM and Software defined radio (SDR) System.
Read moreWhat is UMTS explain its architecture?
UMTS system uses the same core network as the GPRS and uses entirely new radio interface . The new radio network in UMTS is called UTRAN (UMTS Terrestrial Radio Access Network) and is connected to the core network (CN) of GPRS via Iu interface.
Read moreWhat are the parts of 3G architecture?
There are three major parts to a 3G mobile network:
Read moreWhat is 2G and 3G architecture?
The infrastructure of 2G and 3G cellular networks are similar. They comprise an air interface between the user’s mobile device and the base station and two core networks; one for circuit-switched voice and another for packet-switched data .
