OVERVIEW
Wireless Band Selective Repeaters are cost effective and reliable solutions designed to extend and improve the coverage area of UMTS communication systems. LTE Band Selective Repeaters amplifies in both directions, uplink and downlink a continuous bandwidth, factory tuned. The presence of a Repeater provides to the 4G communication system with a high channel occupancy rate, since coverage is extended beyond site coverage. Typical applications of this line of boosters are indoor situations such as tunnels, buildings, subways, and outdoor scenarios such as stadiums, rural areas and dense urban areas.
