13-centimeter Band

13-centimeter Band

The 13 centimeter, 2.3 GHz or 2.4 GHz band is a portion of the UHF (microwave) radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis. The amateur radio band is between 2300 MHz and 2450 MHz. The amateur satellite band is between 2400 MHz and 2450 MHz, and its use by satellite operations is on a non-interference basis to other radio users (ITU footnote 5.282). The license privileges of amateur radio operators include the use of frequencies and a wide variety of modes within these ranges for telecommunication. The allocations are the same in all three ITU Regions.

In the 2300-2400 MHz range the band is also allocated to the Mobile service on a Primary basis which in practice leads to some challenging sharing scenarios and inconsistent allocations to amateurs at national level.

Above 2400 MHz amateur stations must accept harmful interference caused by industrial, scientific, and medical equipment operating in the band. The most common ISM devices that operate in the band are microwave ovens.
