Office of Engineering and Technology Requests Comment on the Public Trial of Comsearch’s TV Bands Database System

The Commission’s Office of Engineering and Technology (OET) is requesting comment on the 45-day public trial of Comsearch’s TV bands database system that was completed on April 9, 2014.

This database system is designed and intended to support the operation of low power unlicensed transmitting devices on unoccupied spectrum within the broadcast television bands (TV bands). This unoccupied spectrum is commonly known as the TV “White Spaces.” Comsearch has provided a summary report on the trial of its TV bands database system to OET.

This summary report identifies: 1) problems/concerns reported and their disposition and 2) descriptions of changes made by Comsearch to the channel availability calculator or registration systems during the trial period.
