Abstract:
The invention provides an increase in the radio coverage area (10) of a base transceiver station (100) having access to multiple transceivers (102, 104, 106, 108) by dedicating at least one of the transceivers (102) for BCCH data. This BCCH transceiver (102) is connected to an antenna arrangement (120) 5 comprising at least two antenna elements (121, 123; 125, 127). Increased BCCH radio coverage (30) is achieved by providing antenna hopping among the at least two antenna elements (121, 123; 125, 127) for the BCCH. Correspondingly, increased TCH coverage (20) is achieved by providing frequency hopping among at least two carrier frequencies for the TCH. The 10 coverage (10) of the base transceiver station (100) is defined as the intersection of the BCCH radio coverage (30) and the TCH coverage (20).
