摘要

802.15.4a/z enabled IR-UWB TRXs [1–4] are being widely deployed into secured ranging and precise localization applications thanks to their increased resistance against relay attacks and high reliability in non-ideal conditions (e.g., non-line of sight, fading), respectively. However, the recent approval of Wi-Fi 6E (by FCC) in the 6-to-7.125GHz spectrum with up to 25dBm EIRP, demands a significant increase in the blocker performance of the existing 802.15.4a/z receivers. This poses a severe challenge to the further proliferation of 802.15.4a/z applications, especially involving mobile and IoT devices, which also need low-power consumption for battery-powered operation.
