What does sub6 mean?

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.

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

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
