Many people know that the fifth generation of wireless network technology has been wrapped in controversy from the get-go, but don't really understand what it is and how it works.
In essence, 5G currently makes for the fastest data transfer rates and the lowest latency (delay) one can experience. It also allows for more devices to simultaneously join a network. Besides facilitating everyday activities that rely on connectivity, 5G is expected to boost developments in the transportation and medical industries (to name but a few).
Although 5G is already being deployed across the globe, the technology is still in its very early stages, and just how much faster it is than 4G is yet to be seen. While some experts speak of a tenfold speed increase, others bet that 5G could multiply 4G data transfer rates by 100 once it's fully rolled out.
To achieve its fullest potential, 5G technology operates over millimeter-wave (high-band) radio-frequency. Unlike the low-band spectrum, the high-band range doesn't support signal propagation over long distances. It's also easily blocked by walls, trees, and other hard surfaces. Due to these restrictions, 5G requires more transmission masts, and those must be closer to our homes – which has fueled fears and conspiracy theories.
