Ultra wideband technology is available in several countries all over the world. Of course, the regulatory status and the specific UWB frequency bands allowed in each country may differ.
For example, in the United States, the technology is regulated by the Federal Communications Commission FCC and the allowed frequency range is the same as the available frequency, which is from 3.1 to 10.6 GHz. This allows the technology to be used in applications such as radar, location based services, and communication.
In Europe the technology is regulated by the European Telecommunications Standards Institute (ETSI). Even though the technology is also available within the range of 3.1 to 10.6 GHz, the institute only allows applications in the range of 6 to 8.5GHz.
Japan’s UWB technology is regulated by the Ministry of Internal Affairs and Communications and is available within the range of 3.4 to 4.8 GHz, and 6.0 to 10.6 GHz.
