The document describes a wireless network setup in a rural area in Italy consisting of the following key elements: 1. A ring network topology with traffic managers and switches to efficiently route data between access points (APs) and a network operations center (NOC) then to the wide area network (WAN). 2. AP towers are placed every 3 meters along the ring with directional antennas providing 360 degree coverage. 3. Components include 5GHz backhaul radios, 5W 2.4GHz APs, client CPE devices, and a managed switch to support the ring topology. 4. A network management system provides monitoring and billing functions.

15. The 16dBi yagi access antenna enables the “last mile” connection to customers. The units are the client side access points/transponders and antenna. They connect to a customer’s computer or router in minutes using CATV cable and a DC power adapter. They are weather proofed with O rings. They include mounting hardware. There are 3 variants (normal, medium and long range). Yagi booster antennas and cables are included to further improve signal strength and reduce interference. This improves quality of service and reduces customer complaints. Up to 20km range.
