Abstract
Abstract A method of, and means for, exchanging a communicated signal with a base site (10) by a communication unit (20) within a cellular system is provided. The method includes the steps of, and means for, transceiving the communicated signal under a broadband format while active and receiving the communicated signal under a narrowband format while idle.
