5G,which is short for “fifth generation”of cellular mobile communications. 5G is best understood terms of its predecessors — 2G(GSM), 3G (UMTS) , and 4G (LTE) . 5G is a WLAN ecosystem which supports wide frequency range with low-latency (1 msec end-to end latency).
5G is rapidly approaching and brings about more improvements .Let’s take a look at the performance of 5G as below:
*High data rate
20 Gbps in the downlink (DL) and 10 Gbps in the uplink (UL）
*Massive device connectivity
100 x more connected devices
*Higher system capacity.
RAN latency ：<1ms
*Energy saving & Cost reductions
Energy savings for networks & terminals
Reduced network costs
