Fast and Accurate TIS Testing Method for Wireless User Equipment With RSS Reporting
TLDR
A fast and accurate total isotropic sensitivity testing method for wireless user equipment based on radiated sensitivity measurement and received signal strength (RSS) reporting is proposed in this paper.Abstract:
A fast and accurate total isotropic sensitivity (TIS) testing method for wireless user equipment based on radiated sensitivity measurement and received signal strength (RSS) reporting is proposed in this paper. Innovative techniques for avoiding the effects of RSS reporting errors on TIS accuracy and reducing the total TIS measurement time are presented and incorporated into the testing procedures. The proposed method is suitable for receiver sensitivity testing of single input, single output radio systems having RSS reporting such as cellular communication, WiFi, and Bluetooth systems.read more
