Accuracy of UWB Ranging over Multimode Fiber With and Without In-Band WLAN Interference
Remote positioning of the ultra wide band (UWB) wireless technology based ranging systems using the radio over multimode fiber (RoMMF) technology is investigated here. The ranging accuracy of such a system with various fiber lengths is studied. Another aspect of the study involves the evaluation of the impact of a coexistent in-band wireless local area network (WLAN) signal (802.11a) on the accuracy of UWB ranging capabilities. The impact of a co-existent UWB signal on 802.11a WLAN performance is also evaluated using error vector magnitude (EVM) measurements.
