4.5. Summary
In this chapter, we explored the aggregate impact of multiple UWB sources on 802.11a devices, 802.11b devices, GPS receivers, and CDMA-based cellular systems, based on theoretical analysis of the uniform distribution of UWB transmitters around a victim receiver. The analyses have shown that the most damaging impact from UWB transmitters is on 802.11a WLAN devices. The reason for the large impact is that 802.11a devices overlap with the UWB transmission band assigned by the FCC and ETSI (3.1 GHz to 10.6 GHz). In contrast, 802.11b devices, GPS receivers, and cellular systems all experience out-of-band interference.
The theoretical analysis has shown that despite being out of the UWB transmission band, 802.11b devices will also suffer ...
