Eliminating non-linear RSS reporting error in a radiated RSS-based TIS testing method

A fast total isotropic sensitivity (TIS) testing method based on radiated sensitivity measurement and received signal strength (RSS) reporting is studied in this paper. An innovative method for eliminating a non-linear system error in RSS reporting is presented and incorporated into the testing procedures. Compared to the methods specified in the Cellular Telecommunications and Internet Association (CTIA) test plan, the improved fast TIS testing method can considerably reduce measurement uncertainty while maintaining the fast testing speed. Thus, it is very suitable for receiver sensitivity testing of single input single output radio systems having RSS reporting, such as cellular communication, WiFi, and bluetooth systems.
