Repeater 'On-frequency' with optimised efficiency for digital radio networks like GSM, DCS 1800, PCS 1900 and others

摘要

The ON-frequency repeater allows optimal efficiency for digital radio networks, GSM, DCS 1800, PCS 1900, and the like. The repeater uses channel amplification paths to optimise the efficiency and thus reduces the output power with a high frequency output power per channel up to several watts. The supply power consumed is further reduced by silent connection of unused system parts in non-operational or low operation time periods. By mute connection of down-link speech channels and uplink paths, control results by analysis of the uplink spectrum. IMAGE
