Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), [ 1 ] which includes sub-7 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to ...
For providing a wide range of services, 5G networks can operate in three frequency bands—low, medium or high. 5G can be implemented in low-band, mid-band or high-band millimeter-wave. Low-band 5G uses a similar frequency range to 4G smartphones, 600–900 MHz, which can potentially offer higher download speeds than 4G: 5–250 megabits per ...

Professional wireless microphones used the 700 MHz band until 2010 when they were made illegal, but equipment still exists in use that may interfere with 3G and 4G technologies. [ 10 ] Due to immediate adjacency to channel 51 lower 700 MHz A block license holders were prohibited to use it within channel 51 station service areas.
Next generation 5G cellular networks, which began deploying in 2019, use higher frequencies in or near the millimetre wave band, 24 to 52 GHz. [9] [10] Millimetre waves are absorbed by atmospheric gases so 5G networks will use smaller cells than previous cellular networks, about the size of a city block. Instead of a cell tower, each cell will ...
Radio frequency (RF) energy at power density levels of 1–10 mW/cm 2 or higher can cause measurable heating of tissues. Typical RF energy levels encountered by the general public are well below the level needed to cause significant heating, but certain workplace environments near high power RF sources may exceed safe exposure limits.

Although both ADS and 5G use radio waves, 5G transmits over a much lower frequency which is safe for humans. [21] Moreover, 5G transmits at a much lower power than ADS. 5G frequencies are used for crowd dispersal; 5G maps the insides of bodies and homes; 5G replicates inside the body and causes re-radiation
