Networks on LTE bands 7, 28 (LTE-FDD) are suitable for global roaming in ITU Regions 1, 2 and 3. Networks on LTE bands 1, 3 (LTE-FDD) are suitable for roaming in ITU Regions 1, 3 and partially Region 2 (e.g. Costa Rica, Venezuela, Brazil and some Caribbean countries or territories. Networks on LTE band 20 (LTE-FDD) are suitable for roaming in ...

Bluetooth devices intended for use in short-range personal area networks operate from 2.4 to 2.4835 GHz. To reduce interference with other protocols that use the 2.45 GHz band, the Bluetooth protocol divides the band into 80 channels (numbered from 0 to 79, each 1 MHz wide) and changes channels up to 1600 times per second.
Super high frequency (SHF) is the ITU designation [1] [2] for radio frequencies (RF) in the range between 3 and 30 gigahertz (GHz). This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from one to ten centimetres. These frequencies fall within the microwave band, so radio waves with these ...
The amateur satellite band is between 1260 MHz and 1270 MHz, and its use by satellite operations is only for up-links on a non-interference basis to other radio users (ITU footnote 5.282). The allocations are the same in all three ITU regions. [1] In the United Kingdom the band is between 1240 MHz and 1325 MHz. [2]
WA1ZMS and W4WWQ later set another record of 1.42 kilometres (0.88 mi) on 403 GHz using CW on December 21, 2004. [6] [5] In Australia, a distance record on 324 GHz of 0.025 kilometres (0.016 mi) was set by stations VK3KH and VK3XPD on August 21, 2011. On November 8, 2020, a distance record on 30 THz of 0.060 kilometres (0.037 mi) was set by ...
The L band is the Institute of Electrical and Electronics Engineers (IEEE) designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz (GHz). This is at the top end of the ultra high frequency (UHF) band, at the lower end of the microwave range.
