DSA Publishes Updated Rules for TV White Space Technology
Tuesday, January 09, 2018 | Comments

The Dynamic Spectrum Alliance (DSA) announced the publication of new model rules for TV white space (TVWS) technology. The new model rules will provide governments, policy-makers and regulators with the tools necessary to enable the quick and efficient deployment of TVWS networks to help bridge the digital divide and support the internet of things (IoT).

Replacing the original version published in 2014, the updated model rules offer higher availability for dynamic spectrum devices and stronger protection for incumbent users. They are based on the regulatory environments put in place by Ofcom in the United Kingdom and the U.S. FCC, incorporating learnings from the operation of TVWS networks, including DSA member Nominet’s experiences running its TVWS services.

“We are very proud to be releasing the latest TVWS model rules, incorporating the experience of many DSA members who are leaders in TVWS technology and deployment,” said Kalpak Gude, DSA president. “The alliance has long been championing TVWS technology to connect those in underserved and rural locations, which will in turn help to bridge the digital divide. Our membership consists of organizations at the forefront of TVWS developments, and we will continue to work together to ensure global connectivity, while maintaining the most effective and efficient use of spectrum, is achieved.”

TVWS refers to unused frequencies in the wireless spectrum between TV broadcasts. The new rules are designed to facilitate and encourage international regulatory harmonization for TVWS, and to help countries where creating a bespoke regulatory environment for TVWS from scratch is difficult and time intensive because of limited resources and the nature of the process of developing new regulations.

The revised DSA model rules enable flexible network topologies such as mesh networks; TVWS in high-speed, long-distance scenarios such as on trains; and a more streamlined regulatory framework to facilitate market growth. In any location, rules must be in place to ensure that TVWS users will not cause interference to incumbent users, such as television broadcasters and domestic television users.
