VNL World GSM Transmission system
Developing a solar-powered radio transmission system
VNL commissioned Sigma Connectivity WSI to solve this challenge, which meant designing, developing and testing the necessary hardware and software for the entire rural radio transmission system. Sigma Connectivity created a point-to-point and point-to-multipoint system, based on a proprietary radio protocol, that could cover a large area at a low cost. The point-to-point links have a range of up to 20 kilometers and the point-to-multipoint links have a range of up to five kilometers.
