Advanced mobile phone service: Cell-site hardware

The hardware facilities of the amps cell site connect the mobile radio customer to the land telephone network and perform actions necessary for rf radiation, reception, and distribution; voice and data communications and processing; equipment testing, control, and reconfiguration; and call setup, supervision, and termination. Cell-site operational control is achieved partially through wired logic and partially through programmable controllers. This paper describes the cell-site functional groups, their physical characteristics and design, and the ways they interface with the rest of the amps system.
