What is cellular sub6?

Sub-6 GHz 5G refers to 5G deployments using spectrum under 6 GHz . This mostly refers to Sprint’s mid-band 2.5 GHz spectrum as well as the low-band 600 Mhz used by T-Mobile and U.S. Cellular as well as AT&T at 850 Mhz.30 Oca 2020

Sub-6 GHz 5G (mid-band 5G), by far the most common, will usually deliver between 100 and 4,400 MBit/s but will have a much further reach than mmWave, especially outdoors. C-Band (n77/n78) will be deployed by various U.S. operators in 2022.

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.16 Kas 2021

mmWave refers to higher frequency radio bands ranging from 24GHz to 40GHz, and Sub-6GHz refers to mid and low-frequency bands under 6GHz . Low-frequency bands are under 1GHz, while mid-bands range from 3.4GHz to 6GHz and are not considered “mmWave.” mmWave 5G networks are ultra-fast, but they’re also ultra-short range.10 May 2021

5G is offered in two distinct variants — sub-6 and mmWave. As RootMetrics explains, these are essentially codenames for different types of wireless spectrum. sub-6 refers to data below the 6Ghz spectrum , while mmWave accounts for data sent above 6Ghz.22 Haz 2021
