5G networks are the next generation of mobile internet connectivity, offering faster speeds and more reliable connections on Smartphone’s and other devices than ever before.
It is also the latest generation of cellular mobile communications. It succeeds the 4G (LTE/WiMax), 3G (UMTS) and 2G (GSM) systems. 5G performance targets high data rate, reduced latency, energy saving, cost reduction, higher system capacity, and massive device connectivity.
The question we should be asking ourselves is “Is it worth the Hype”
Like the earlier generation 2G, 3G, and 4G mobile networks, 5G networks are digital cellular networks, in which the service area covered by providers is divided into a mosaic of small geographical areas called cells. Analog signals representing sounds and images are digitized in the phone, converted by an analog to digital converter to a sequence of numbers, and transmitted as a digital signal, a stream of bits. All the 5G wireless devices in a cell communicate by radio waves with a local antenna array and low power automated transceiver (transmitter and receiver) in the cell, over frequency channels assigned by the transceiver from a common pool of frequencies, which are reused in geographically separated cells. The local antennas are connected with the telephone network and the Internet by a high bandwidth optical fiber or wireless backhaul connection. Like existing cell phones, when a user crosses from one cell to another, his mobile device is automatically “handed off” seamlessly to the antenna in the new cell.
Their major advantage is that 5G networks achieve much higher data rates than previous cellular networks, up to 10 Gbps; which is faster than current cable internet, and 100 times faster than the previous cellular technology, 4G LTE. Another advantage is lower network latency (faster response time), below 1 millisecond, compared with 30 – 70 ms for 4G. Because of the higher data rates, 5G networks will serve not just cell phones but are also envisioned as a general home and office networking provider, competing with wired internet providers like cable. Previous cellular networks provided low data rate internet access suitable for cell phones, but a cell tower could not economically provide enough bandwidth to serve as a general internet provider for home computers.
Earlier has shown that although 5G would end up becoming a data sucking demon, but would be faster than its predecessors and in so doing would give room for further developments in science and more digital possibilities
