The transceiver is implemented at a vehicle: receives a first RF signal from a portable access device via multiple antennas; transmits a second RF signal from the vehicle to the portable access device; and receives a third RF signal from the portable access device. The third RF signal indicates an AOD of the first RF signal or a second AOA of the second RF signal as received at the portable access device. The access module: estimates a first AOA of the first RF signal; determines a resultant AOA based on the first AOA and the AOD or the second AOA; determines a location of the portable access device relative to the vehicle based on the resultant AOA; and permits access to the vehicle or control of a portion of the vehicle based on the location of the portable access device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ultra-high frequency low energy based phone as a key access to a vehicle using two-way communication for multipath mitigation","description":"A system includes a transceiver and an access module.
