Abstract
A mobile computing device comprises a housing, a telephony circuit and a relative positioning circuit. The housing is configured to be held in a hand during use. The telephony circuit is coupled to the housing and is configured to communicate wireless telephony signals. The relative positioning circuit is coupled to the housing and is configured to determine at least one of a distance and a bearing to an object based on wireless signals received from the object.
