Abstract: Noise floor degradation detection may be provided. First, an incremental packet loss rate for a secondary radio may be calculated that indicates an impact on packet reception on the secondary radio due to transmissions by a primary radio. The secondary radio and the primary radio may comprise an access point. Next, it may be determined that the incremental packet loss rate is greater than a predetermined value. A configuration of the access point may be changed in response to determining that the incremental packet loss rate is greater than the predetermined value.

Abstract: Presented herein are infrastructure triggering techniques for secure Ultra-Wideband (UWB) ranging. In one example, a method may include providing UWB ranging parameters to a mobile device via a first radio communication, wherein the first radio communication is a non-UWB radio communication; and triggering the mobile device to perform UWB ranging with a UWB anchor, wherein the triggering is performed using a second radio communication. In another example, a method may include, obtaining, by a mobile device, UWB ranging parameters for a geographic area; obtaining a UWB ranging instruction for the geographic area; and performing UWB ranging with a target UWB anchor based on the UWB ranging parameters and the UWB ranging instruction.
