A method and system for wireless communications between base and mobile stations use reference signals transmitted from base stations prior transmission of data signals. Tab connectors extend from internal circuits into the internal region of the fusible link receptacle, and a rib is formed on the internal surface of the perimeter wall and extends to a point above the leading edges of the tab connectors. By effecting vulcanization, a vulcanized elastomeric compound is produced containing good physical properties for use as tread stock for a pneumatic tire. A program command and access control data including a new access code are transmitted wirelessly from a hand-held program unit or the like.
