What is 5G sub-6 and mmWave?

Radio frequency bands below 6 GHz (6,000 MHz) . Prior to 2019, all radio frequency bands used for mobile phones were below 6 GHz.

Sub-6GHz 5G is essential for blanket coverage and bandwidth, while mmWave offers higher speeds over shorter distances . As such, mmWave deployments are limited to short distances, such as a few streets, and areas that benefit most from extreme high bandwidth, such as stadiums and city centers.

Sub-6GHz 5G is faster than 4G , but it doesn’t offer the blazing-fast speeds that you can get with mmWave. Since it has a longer range and can better penetrate objects, it’s much more affordable for carriers to implement. It’s worth noting that mmWave 5G offers greater bandwidth, relieving network congestion.10 May 2021
