BARCELONA, Spain–InterDigital, Inc., today announced the successful trial of Wi-Fi® over dynamically managed unlicensed spectrum at a macrocell level. The trial, extending standards-based technology, opens the door to various applications and is immediately available for field trials.

“The platform is easily adaptable to other spectrum bands, such as the FCC-proposed 3.5 GHz Citizens Broadband Service, and is designed for diverse ‘shared spectrum access’ applications – including those outlined in the report to the President’s Council of Advisors on Science and Technology.”

Using a unique amplifier in combination with both database- and sensing-based spectrum management, the company was able to successfully stream high-bandwidth video at a power range that would cover roughly three kilometers in suburban settings or up to five kilometers in rural applications. The approach provides operators with an eventual solution to Wi-Fi backhaul and other applications.

“InterDigital’s DSM technology platform is a breakthrough in the use of TV White Space as a networking platform, providing both reliability and performance in the harsher shared spectrum environment. This solution is a first in enabling Wi-Fi to operate over macrocell ranges, supporting a variety of indoor and outdoor use cases, including backhaul, M2M and metro Wi-Fi deployments,” said Jim Nolan, Executive Vice President of InterDigital’s Innovation Labs. “The platform is easily adaptable to other spectrum bands, such as the FCC-proposed 3.5 GHz Citizens Broadband Service, and is designed for diverse ‘shared spectrum access’ applications – including those outlined in the report to the President’s Council of Advisors on Science and Technology.”
