Abstract: The apparatus includes a first xPlexer, coupled to a first antenna, including first and second filters; a second xPlexer, coupled to a second antenna, including third and fourth filters; a first switched xPlexer including fifth and sixth filters coupled to the second filter of the first xPlexer; a second switched xPlexer including seventh and eighth filters coupled to the fourth filter of the second xPlexer; a first transceiver coupled to the first filter of the first xPlexer and selectively coupled to the fifth filter of the first switched xPlexer; a second transceiver coupled to the third filter of the second xPlexer and selectively coupled to the seventh filter of the second switched xPlexer; a third transceiver selectively coupled to either the fifth or sixth filter of the first switched xPlexer; and a fourth transceiver selectively coupled to the seventh or eighth filter of the second switched xPlexer.

Abstract: A method for precision finding with two radio technologies includes: determining a first distance to a wireless node based at least in part on a first positioning technology having a capability of determining distances to objects within a first range; determining, based on the first distance being within a second range, a second distance to the wireless node based on a second positioning technology having a capability of determining distances to objects up to the second range, wherein the second range is less than the first range; and outputting location information for the wireless node based at least in part on the second distance.

Abstract: This disclosure provides methods, devices, and systems for performing passive scanning operations on one or more wireless channels. In some implementations, a wireless communication device configures an off-channel scan time and a passive scanning period for passive scanning operations based on latency requirements of a low-latency application, and selects a home channel dwell time for the passive scanning operations. The wireless communication device may perform the passive scanning operation by alternating between listening for beacon frames on one or more second wireless channels for the configured off-channel scan time and dwelling on a home channel for the selected home channel dwell time during a first portion of the configured scanning period. The wireless communication device also may listen for beacon frames on the one or more second wireless channels during a second portion of the configured scanning period that is defined by the selected home channel dwell time.
