The DB6M from Shyam Telecom Limited is a modular dual band RF repeater that operates from 900 to 2100 MHz. It is compatible with GSM, CDMA, iDEN, WCDMA and GSMR technologies. The repeater can be used in up to 6 sub bands within its frequency range. This band-selective system is specifically designed for networks with noncontiguous frequency spectrum allocation. It is available in a wide range of RF powers, and extends the coverage area of mobile networks where installation of additional Base Stations are not financially viable.
