An Android phone, showing that it is connected to a 5G network. In telecommunications, 5G is the fifth generation of cellular network technology, which mobile operators began deploying worldwide in 2019 as the successor to 4G. 5G is based on standards defined by the International Telecommunication Union under the IMT-2020 requirements, which outline performance targets for speed, latency, and ...
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 ...
Some 5G networks use the 25-39 GHz frequency band, but there are also two other frequencies available.
Radio waves are defined by the ITU as: "electromagnetic waves of frequencies arbitrarily lower than 3000 GHz, propagated in space without artificial guide". [5] At the high frequency end the radio spectrum is bounded by the infrared band. The boundary between radio waves and infrared waves is defined at different frequencies in different ...

On November 20, 2018, T-Mobile and Nokia completed their first downlink 5G NR transmission in the 600 MHz frequency compliant with 3GPP 5G standards in Spokane, Washington. 28 GHz only reaches roughly 1 square mile (2.6 km 2), whereas 600 MHz can reach hundreds of square miles. This marks one step closer to a rural 5G network, one highly sought ...
The frequency reuse factor is the rate at which the same frequency can be used in the network. It is 1/K (or K according to some books) where K is the number of cells which cannot use the same frequencies for transmission. Common values for the frequency reuse factor are 1/3, 1/4, 1/7, 1/9 and 1/12 (or 3, 4, 7, 9 and 12, depending on notation ...
