The TB6M from Shyam Telecom is a modular tri band RF repeater that is compatible with GSM, CDMA, iDEN, WCDMA and GSMR technologies. It is equipped with a maximum of six non-contiguous sub bands in a 2+2+2 configuration using three service bands to provide outdoor coverage for mobile signals. This band-selective system is specifically designed for networks for non-contiguous frequency spectrum allocation. Available in a wide range of RF powers, this repeater extends the coverage area of mobile networks where installation of additional BTS would not be financially viable. It is ideal for use in tunnels, on highways, islands, rural locations, hilly terrain and other remote outdoor locations.
