5G technology operates at a wide range of frequency bands, including both sub-6GHz and millimeter wave (mmWave) frequencies.
Sub-6GHz frequencies include the traditional cellular bands below 6GHz, such as the 600 MHz, 700 MHz, 800 MHz, and 900 MHz bands. These bands have been used for cellular communications for many years, and they have the advantage of providing good coverage and penetration through walls and other obstacles.
On the other hand, mmWave frequencies are higher frequencies, above 24GHz, they have a shorter range and are more easily blocked by obstacles such as buildings and trees. But they offer much higher bandwidth and capacity than sub-6GHz frequencies.
5G technology can also use a combination of both sub-6GHz and mmWave frequencies to provide a balance between coverage and capacity, depending on the specific requirements of the application or service.
