G is the latest generation of cellular mobile communication technology, and it is also an extension after 4G(LTE-A, WiMax), 3G(UMTS, LTE) and 2G(GSM) systems. The performance goals of 5G are high data rate, low latency, energy saving, low cost, high system capacity and large-scale equipment connection.
Extended data
The main advantage of 5G network is that the data transmission rate is much higher than the previous cellular network, and the highest data transmission rate can reach 10Gbit/s, which is faster than the current wired Internet and 100 times faster than the previous 4G LTE cellular network. Another advantage is that the network delay (faster response time) is lower than 1 millisecond, while 4G is 30-70 milliseconds.
Because of the faster data transmission speed, 5G network will not only provide services for mobile phones, but also become a general home and office network provider, competing with wired network providers. In the past, cellular networks provided low data rate Internet access for mobile phones, but as a general Internet provider of home computers, cellular phone towers could not provide enough bandwidth economically.
