Infrared Roll-outs
Infra red systems are used by a wide range of GSM cellular operator organizations for approach links between base transmitting stations. They have been found suitable for use in short hops replacing HDSL. Systems that were previously in used in the existing copper networks. Infra red links do not require frequency licensing and hence they have been used in used in urban areas to replace microwave links. Design and installation of License free Infrared Links for Backhaul and Point to point transmission. Maintenance and Servicing of Infra red Links to ensure availability and performance as per Manufacturer specifications.
