What does 5g mean
5g mobile network is the same as the early 2G, 3G and 4G mobile network. 5g network is a digital cellular network. In this network, the service area covered by the supplier is divided into many small geographical areas called cellular. Analog signals representing sound and image are digitized in mobile phones, converted by analog-to-digital converters and transmitted as bit streams.
All 5g wireless devices in the cell communicate with the local antenna array and low power automatic transceivers (transmitters and receivers) in the cell via radio waves. The transceiver allocates channels from the common frequency pool, which can be reused in geographically separated cells. The local antenna is connected to the telephone network and the Internet via a high bandwidth optical fiber or wireless backhaul connection.
Like existing mobile phones, when users cross from one cell to another, their mobile device will automatically "switch" to the antenna in the new cell.
The main advantage of 5g network is that the data transmission rate is much higher than the previous cellular network, up to 10Gbit / s, which is faster than the current wired internet and 100 times faster than the previous 4G LTE cellular network. Another advantage is lower network latency (faster response time), less than 1 millisecond, compared with 30-70 millisecond for 4G.
Due to faster data transmission, 5g network will not only provide services for mobile phones, but also become a general home and office network provider, competing with cable network providers. Previous cellular networks provided low data rate Internet access for mobile phones, but a mobile tower could not provide enough bandwidth economically as a general Internet provider for home computers.
