The most unusual opportunity presented itself when Mikrotiks colleagues from Airpath Wirelessnet Solutions were contacted by The National Technology Centre for Ports, Waterways & Coasts of India.

They needed a link between two sites in the ocean: Tsunami alert and tide reading buoy stations.
Here’s the challenge: all high-speed wireless links require a good line of sight and a clear Fresnel zone for a good connection. Usually, you can achieve this with masts or towers. But what can you do if you want a connection in the middle of the ocean?

After ruling out 24, 60, and 80 GHz solutions, Airpath Wirelessnet turned to the good old 5 GHz connectivity.

“We chose the MikroTik NetMetal because it uses the extended upper part of the 5 GHz spectrum, leading to a much lower probability of interference, as well as high-gain TX Power.” Airpath Wirelessnet Solutions

In the end, they had to use an anchored boat and even the help of experienced divers, but a stable 100 Mbps connection is now in place. NetMetal – not even the vast ocean can stop it.
