, which means it operates using a system of cell sites that carve each area up into different sectors and transmit encoded data through radio waves. Each of these sites needs to be connected to a network"backbone", most often a physical wired connection, and the encoding they use is different depending on the type of network.
In terms of infrastructure, there isn't all that much different about 5G compared to existing cell sites, but the new 5G networks will enable those cell sites to access a much wider band of frequencies than before. 5G networks use OFDM encoding, which is similar to the type used in a 4G LTE network but provides an"air interface" with lower latency and access to more airwaves than 4G LTE.
short-range radio signal known as high-band 5G, which lets you stack up to eight, 100 MHz channels to vastly improve data transfer speeds and latency. Cellular carriers are also able to stitch together 4G and low-band 5G frequencies using something called dynamic spectrum sharing, based on network traffic, to get the most out of their existing 4G network.
