Abstract
A method for alerting a user of a first portable communications assembly that another user of a second portable communications assembly is within a predetermined distance includes the step of receiving a distance signal transmitted by the transmitter in the second portable communications assembly. A distance between the first and second portable communications assemblies based on the distance signal is calculated based on the strength of the distance signal or based on a time stamp embedded in the distance signal. An alert is emitted when the distance calculated between the first and second portable communications assemblies is less than the predetermined distance.
