An electronic receiver may generate a differential detection sequence based on a received symbol sequence and based on a m-symbol delayed version of the received symbol sequence, where m is an integer greater than 1. Each cellular communications device can monitor the cellular network control channel for a pair of target pages within a first time period. The piezoelectric elements are bonded, through a thin layer of metal that is separately provided for bonding, to at least one of the support base and the mirror portion. The Travelling Log entries permit information posted to the Travelling Log to be relayed back to network management personnel. The new configurations enable messages to be sent that are larger than currently allowed and the availability of the new configurations is indicated such that mobile terminals that do not support the new configurations are not impacted.
