Like earlier 2G, 3G, and 4G mobile networks, 5G networks are digital cellular networks in which the service area covered by suppliers is divided into many small geographic areas called cellular. Analog signals representing sound and images are digitized in mobile phones, converted by analog-to-digital converters and transmitted as bit streams. All 5G wireless devices in the cell communicate via radio waves with the local antenna array and low-power automatic transceivers (transmitters and receivers) in the cell. The transceiver assigns channels from a 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 fiber optic or wireless backhaul connection. As with existing phones, when users cross from cell to cell, 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, 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, and 4G is 30-70 milliseconds. Due to faster data transmission, 5G networks will not only provide services only for mobile phones, but will also become general home and office network providers, competing with cable network providers. Previous cellular networks provided low-data-rate Internet access for cell phones, but a cell phone tower could not economically provide enough bandwidth as a general Internet vendor for home computers.
How do 5G devices with high power and high heat consumption dissipate heat?
As 5G is about to "fly into the homes of ordinary people", it is followed by the heat dissipation challenges of various 5G equipment products. How to do a good job of heat dissipation of high power and high heat consumption products in the 5G era has become an trickiest problem that engineers need to face.
