Abstract
This article presents a study on Television White Spaces (TVWS) to solve the connectivity of the WiFi service for the Colombian National Army in rural areas. The study analyzes regulatory aspects and technical equipment to provide a free internet access solution. Video transmission was experimentally validated, using OFDM with USRP N210 radios. With this preliminary analysis, it was possible to understand how the PHY and MAC layers of the 802.22 Standard work to select the appropriate devices.
