The S band ranges from 2.0–4.0 GHz., crossing the imaginary boundary between VHF and SHF at 3.0GHz. It is part of the microwave band of the electromagnetic spectrum. The S band is used by weather radar and some communications satellites. The 10-cm radar short-band ranges roughly from 1.55 to 5.2 GHz.
In the U.S., the FCC approved Digital Audio Radio Satellite (DARS) broadcasts in the S band around 2.3 GHz, currently used by Sirius Satellite Radio and XM Satellite Radio.
