Abstract: The long distance links with low-cost hardware have been used to interconnect rural populations in places where incumbents fail, and it is a global initiative for developing countries. This initiative has been promoted by various agenciesas: TIER, ICTP, ESLARED Foundation. This article describes the implementation of a radio link between the Villonaco Hill and the National University of Loja, using the experience gained by various agencies in the development of WiFi-based Long Distancetechniques. WiLD network with links as long as 50-100 km have the potencial to provide connectivity at substantially lower costs than traditional approaches. However, real-world deployments of such networks yield very poor end-toend performance. First, the current 802.11 MAC protocol has fundamental shortcomings when used over long distances. Second, WiLD networks can exhibit high and variable loss characteristics, thereby severely limiting end-to-end throughput. In the implementation was used thewell-known Linksys WRT54G routers, where the factory firmware was replacedfor DD-WRT firmware. We also present the feasibility of the radio link through Radio Mobile Software, and the results using the PING command.
