OSPF over unstable wireless

We enhanced Mikrotik's implementation of Cisco's OSPF protocol with scripts linking signal quality to route cost; therefore insuring that signal fade on the active station would not disrupt internet traffic.
The scripts run every 6 seconds and change route cost according to tx and rx signal levels.

The multipath solution

We erected multiple links in different locations and altitudes on the Lebanese side.
This we believe creates multiple physical paths to the Cyprus station therefore when signal fade is large on one of the stations (one of the paths) the other station would take over the traffic.

Big and small challenges.

Although the challenges at the beginning looked impressive, the truth was that everything done so far was the easy part, aligning the antennas was not easy, but did not prove hard.

Later on when this link was to be commercially tested, the real challenge surfaced. How to make it commercially stable?


The biggest problem it turned out is signal fade, immense unpredictable seasonal signal level variations that make the link very unstable especially in hot humid days.
