Abstract
Official abstract text for this publication.
Methods and apparatuses for radio proximity detection are disclosed. In one example, a method for determining a proximity of a mobile radio includes determining an initial range of a mobile radio in relation to a base radio, and processing the initial range determination to determine whether to make a refined range determination utilizing signal measurements from both a base radio first antenna and a base radio second antenna.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for determining a proximity of a mobile radio comprising: determining an initial range of a mobile radio in relation to a base radio comprising estimating a distance utilizing a RSSI value from a signal received at a base radio selected antenna; and processing the initial range determination to determine whether to make a refined range determination utilizing signal measurements from both a base radio first antenna and a base radio second antenna.…
