The management of the radio frequency spectrum has traditionally been a centralized process, with the access to spectrum overseen by a regulatory body. However, as technology has progressed, methods allowing dynamic spectrum access have begun to be developed to improve spectrum efficiency. A shift away from conventional licensing approaches could lead to a more flexible, adaptive administrative environment by enabling opportunistic use of the radio frequency spectrum. Such techniques for the use of TVWS have the potential to improve spectrum efficiency while facilitating the introduction of new wireless communications applications in Canada.

Some respondents express some apprehension about the introduction of TVWS devices due to the potential for rapid proliferation, especially in the context of licence-exempt operation among licensed systems. On the other hand, appropriate technical requirements and the ability of these devices to adapt their operation in real time should ensure that incumbent users do not suffer harmful interference. Industry Canada believes that the regulatory approach described in this document will provide the necessary measures to address these concerns.

Industry Canada will also closely monitor international regulatory developments, and will make appropriate regulatory changes as further experience is gained. It is noted that TVWS rules in the United States have been finalized and remaining legal obstacles to related TVWS deployment have been resolved. The development of rules and regulations for TVWS use are also moving quickly in many other countries, including in the United Kingdom, where rules development is particularly advanced.

Despite the potential that repurposing of some TV spectrum below 698 MHz in the United States might lead to calls for similar action in Canada, Industry Canada does not see this as a reason to delay the introduction of TVWS devices. If Canada were to follow the United States, available spectrum would be reduced and fewer geographical areas would be available for the operation of TVWS devices. However, proponents have indicated their belief in the ongoing viability of TVWS use regardless of whether such changes take place.

It is expected that the introduction of the use of TVWS devices will enable the development of new techniques for managing the radio frequency spectrum while easing spectrum shortages and enabling more options for wireless broadband and Internet services for consumers.
