Abstract
A wireless communications system has a plurality of base stations , a plurality of mobile vehicular repeater units , and a plurality of portable units . In a public safety network context, each mobile vehicular repeater unit is associated with a portable unit , and both are associated with a single user. The object is for the user to be able to access the wireless network for any geographic location. In cases where a geographic area is shadowed from a base station and communication directly between the portable unit and the base station is not possible, it is beneficial to use the mobile vehicular repeater unit as a vehicular repeater to relay communications between the portable unit and the base station . When the mobile vehicular repeater unit is operating as a repeater and communicating with the portable units, the frequency plan for transmission and reception is reversed.
