University Ocean Trials Deliver Wireless Wi-Fi Across 7 Miles of Open Ocean

Oceanographic study utilizes non line-of-sight obstruction penetrating multi-polarized antenna technology to monitor buoys and roaming vessels in open waters of Gulf of Mexico.

As a leading research institute of marine sciences a team of researchers from the Centre of Ocean Technology, University of South Florida, has become a test bed for a variety of marine research. The centre sought to utilize wireless wi-fi to monitor research buoys, rov’s and various research vessels on the open ocean.

Providing wireless signals across water is difficult due to the highly reflective nature of water especially choppy or wavy waters. Pragnesh Bhanushali, Microsystems Electrical Engineer University of South Florida Centre for Ocean Technology sought out the newest available antenna technology from Wifi-Plus antenna to address the known problems on the water.

Mr. Bhanushali commented, ”We had one of our nodes set up on a Coast Guard range marker (40feet ht) and 7 miles away from the shoreline tower at the University building. We had a number of sensor nodes on buoys and a few mobile platforms including an ROV and boats as clients to the remote node. We were able to monitor all our data and remote devices from the University building on shore real time. The multi-polarized antennas worked great even in a difficult ocean environment out performing higher gain antennas. The received signal strength was consistently stable.”

They had not seen this with standard antenna’s available. This will open a new form of communication for ocean going and shoreline applications such as providing internet for small vessel that may not have radar for weather updates.

Mr. Bhanushali, (The project spokesman.) continued by saying,“ As a result of our success using Wifi-Plus Antenna equipment, other groups within the university and have expressed an interest in using it also. This broadens our capability in remote ocean sensing, environment monitoring and other navy and port security related applications. Presently, we are scaling up the existing network using mesh topology.”

Dennis Broderick, President of Wifi-Plus said,” Real world installations do not allow for Line of sight. The wireless world is full of obstruction that has hindered the adoption of wireless services. We are proud to be of service to the University's research and look forward to new and future success in improving the world around us.” He continued, "Our antenna will allow rapid installation of wireless services to the hotel, RV parks, marina, and anyone else who is finding wireless difficult to deploy due to the obstructed nature of the world we live. We are excited about the results accomplished in this trial and the credibility for Multi-Polarized antenna technology.”
