The document discusses installing mobile signal transmitters on bridges and flyovers in Mumbai to reduce call drops. Due to the height of flyovers, signals were weak, causing drops. The Maharashtra State Road Development Corporation is allowing installation of transmission equipment on street light poles along flyovers. This has helped boost signals and reduced drops. The technology is also being used for future infrastructure projects like sea links and metros.

4. MSRDC installs mobile signal transmitter on bridges, flyovers BRIDGING THE GAP: Living in a city peppered with flyovers, has meant living with call drops for Mumbaikars. But not for much longer. Flyovers and bridges in Mumbai, Navi Mumbai and Thane, which are notorious 'dead spots' for mobile phone networks, are now being fitted with signal-transmitting equipment to prevent call drops. Maharashtra State Road Development Corporation (MSRDC) director (environment) and project in-charge P K Das said, "Instances of call drops are high along flyovers, mainly due to the height. The transmission equipment will help boost the signal strength." Shiv Shankar Lature, managing director of Suyog Telematics, the company handling the installations, promised that call drops on flyovers and bridges would become history with the new transmission equipment. "All 32 flyovers in Mumbai will be covered. Of these, the Vashi and Airoli bridges are the most crucial since they have never been covered by cellphone companies," he said.

5. Using street lights Since it is not possible to erect the usual network towers atop flyovers and bridges, MSRDC allowed the installation of transmission equipment atop street light poles. "The equipment is advanced in nature. It does not require the cumbersome power supply equipment unlike the traditional tower units," said Lature.Installation work has been completed on 22 flyovers. For future projects This technology is also being used to overcome transmission difficulty along all future infrastructure projects including the Bandra-Worli Sea Link, metro rail and monorail. The absence of this equipment would have made things very difficult for cell phone users. A BTS may cover an area of 30 - 40 sq kms. However, in a congested, urban location, the BTS coverage area is much smaller. BTS can be considered as complex radio modems and have little other function. A list of hardware located at a cell site includes power sources, interface equipment, radio frequency transmitters and receivers, and antenna systems .
