A robust Point to Point array of radios to deliver wireless internet over long distances. Posted: March 27, 2014
Wireless internet can provide Last Mile internet with good reliability and decent bandwidth. This PDF details a robust Point to Point array of radios to deliver internet in hard hill country without DSL, or Fiber services. Written in 2006, the 802.11ABG hardware shown here is outdated, but the design is not. Modern wireless radio drivers and 802.11n and multiband routers can achieve much higher data rates using the design and antennas in this example. The operating system distribution, Voyage Linux, is still in current distribution (2014), and OpenWRT can be substituted for Voyage with little effort. One of the best features of this design is the fault tolerance and failure recovery methods. Users at the endpoints can invoke a system restart by simply unplugging their LAN cables for specific amounts of time.
This document outlines the construction of a Non-WDS backbone repeater array
using MadWifi, OpenVPN and Shorewall. Datastream integrity and security is
managed using OpenVPN and WPA2. Shorewall manages netfilters and iptables to
control routing and tunnels. An optional CPE AP is setup using WRAP3 as a station.
This AP is secured by WPA2 and routes to the VPN on WRAP3.
