Abstract
Certain aspects of the present disclosure relate to techniques for supporting television white space (TVWS) communication. In an aspect of the present disclosure, a low-rate TVWS enabler (Mode II wireless communication device) may provide initial enablement for all Mode I devices (e.g., access points and user terminals), as well as it may transmit a contact verification signal (CVS) on a regular basis to keep the Mode I devices enabled for the TVWS communication.
