Researchers from Portugal’s Institute of Systems and Computer Engineering, Technology and Science (INESC TEC) report success delivering high-speed internet access powered by helium balloons attached to buoys, vessels, or even windmills.

The Bluecom+ Project demonstrates the viability of delivering internet access using a broadband mesh network operating in the 500MHz band, currently occupied by UHF television channels 19-34. Researchers created a wireless internet network from shore that achieved more than 100 kilometers of coverage offshore, providing access to Wi-Fi and 4G technology-powered internet in the Azores, an archipelago in the mid-Atlantic.

The islands, an autonomous region of Portugal, were selected to test the capability of providing affordable enhanced communications for vessels at sea. Currently, most ships rely on satellite-based communications services, which come at a high cost.

The relatively low frequencies used are capable of penetrating buildings and achieving longer distance coverage, which make them especially suitable for wireless broadband. In the United States, mobile providers are seeking additional spectrum now used by UHF television stations to further expand their wireless networks. In rural areas like the Azores, there is plenty of open channel space to support wireless broadband, as there would be in rural communities currently not served well by DSL or cable broadband.

The project hopes to achieve complete coverage of the Azores, as well as offshore areas around the islands, within the next five years. Bluecom+ is a jointly funded project of Norway, Iceland and Liechtenstein through European Union grants.
