We are privileged trader, supplier and exporter of Dual Band 900 And 2100MHz Low Power (S7) in New Delhi, Delhi, India. CELLBOOST signal Booster is used to provide radio frequency (RF) coverage to areas which either lack signal or lack the required signal strength for adequate mobile phone performance. Insufficient coverage may occur both indoors and outdoors and can include such areas as office buildings, parking garages, apartment buildings, shopping malls and residential homes. The weak coverage problem can be solved by installing an active Booster system designed for use in a multitude of installation configurations. Booster systems provide an effective solution by redirecting, filtering and amplifying the available signal at the pick-up antenna, into the weak coverage area, through a properly selected interior coverage antenna. - Coverage area 500-700 sq ft. - 5 V dc input. - GSM 900 & 2100 network.
