The WilsonPro 1050 cell signal booster system provides significantly enhanced voice and data coverage including 4G LTE deep inside large homes or other buildings by compensating for signal loss caused by long cable runs. As cell signal moves over long lengths of coax cable some is lost, reducing booster system performance. The 1050 booster system addresses this technical problem by employing two separate boosters - a main signal booster and a supplementary inline booster. When the WilsonPro 1050 senses that any incoming signal is too strong and threatens to overload the system, XDR automatically reduces signal gain to compensate for this overload condition while maintaining signal coverage throughout the building. In contrast, competing signal boosters shut down when they reach a maximum incoming signal strength threshold, causing the indoor cell signal to drop out.
