Furthermore, the Federal Communications Commission (FCC) published a first report on the ultra wide band and the technology of the directive, which approved the commercial deployment of ultra-wideband technology. A spectrum mask has been published to ensure that the overclocked signal does not interfere with the bandwidth of other protocols, such as the Global Positioning System (GPS) sensitive device and the WiMAX (Worldwide Interoperability for Microwave Access) agreement. There is a large continuous bandwidth in this spectrum mask, and the effective isotropic radiated power (EIRP) emission level (-41.25dBm/MHz) of the over-frequency bandwidth will be from 3.1GHz to 10. The 6 GHz bandwidth is the ultra-wideband communication technology used. However, because the spectrum used by the WiMAX protocol is 3.6 GHz, the WiMAX protocol overlaps with the ultra-wideband spectrum and interferes with each other.
