Adaptrum demonstrates white spaces technology

July 7, 2011

Adaptrum, a Silicon Valley-based company developing wireless broadband solutions using unlicensed TV white spaces, recently demonstrated its radio system at the Cambridge TV Whitespace Trial launch event in Cambridge, United Kingdom.

Adaptrum's innovative cognitive radio technology uses any available spectrum below 1GHz with a flexible architecture to support different types of services and applications, while meeting stringent interference requirements established by the FCC. As a key demonstration in this June 29 event, Adaptrum established a TV white space broadband connection under extraordinarily challenging propagation conditions and was able to deliver consistent high-throughput data connectivity where other wireless technologies like WiFi fell short.

In the demonstration, the Adaptrum white space system provided the broadband IP connectivity, allowing a client-side Microsoft XBOX to stream live HD videos from the Internet. Also as part of the demo, a live XBOX/Kinect video chat was established between two XBOX/Kinect units connected through the same TV white space connection. These applications were demonstrated under a highly challenging radio propagation environment with more than 120dB link loss through buildings, foliage, walls, furniture, people etc. and with severe multipath effects. To demonstrate the complete TV white space system, the Adaptrum radio system was also interacting with the Microsoft UK TV white space database for the updated channel list at Cambridge.

"We are very pleased that Adaptrum agreed to provide its TV white space system for the Cambridge TV White Spaces Trial. In April, this same system was successfully demonstrated at the National Association of Broadcasters convention in Las Vegas, NV. We look forward to working with Adaptrum in deploying this exciting new technology and demonstrating real-world uses cases and applications using TV white space," said Paul Garnett, director of standards and interoperability, Microsoft.

Adaptrum CEO Haiyun Tang concluded, "We are excited to provide our white space solution for the Cambridge trial. Such trial is exactly what we need to test drive this new technology. Today, as more people are using their wireless devices, we see an increasing gap between the demand and supply sides of wireless bandwidth. Unlicensed technology will play the key role in closing this gap. Just as WiFi has been offloading the majority of wireless data traffic today, TV white space technology, with its superior reach and performance, will provide wireless bandwidth where WiFi cannot.

Unlicensed and lightly licensed spectrum lowers the barrier of entry and encourages innovation on technology, deployment and new business models, which may well be the real answer to our mobile broadband problem. We are pleased to see the world's leading technology companies are standing solidly behind this technology and helping raise the public awareness about TV whitespace so collectively we can help realize the true potential of the public airwave.”
