Estimating the term…
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 typical context, each mobile vehicular repeater unit is associated with at least one portable unit, and both may be associated with a single user. The object is for the user(s) 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 in accordance with an extended coverage mode of operation, to relay communications between the portable unit and the base station. A mobile vehicular repeater unit constructed according to the present invention enters the extended coverage mode of operation in response to receipt of an access request, transmitted by a first of the plurality of portable units. Responsive to that request, a mobile vehicular repeater unit transmits to the portable unit a signal representative of an identification of the upper and lower frequency channel portions.
