Abstract: The primary objective of this study is to define maximum allowable ultrawideband (UWB) equivalent isotropically radiated power (EIRP) levels that can be tolerated by GPS receivers, when used within various operational applications, without causing degradation to GPS operations. These EIRP levels are then compared to the emission levels derived from the limits specified for intentional radiators in C.F.R., Title 47, Part 15.209 to assess the applicability of the Part 15 limits to UWB devices.

Keywords: interference; RF; ultrawideband; UWB; equivalent isotropically radiated power; GPS; intentional radiators; radio frequency; effective isotropic radiated power (EIRP)
