Frequency Coordination for Wireless Mics
The FCC created a framework for the database and opened it to private sector companies who specialize in the administration of databases. The intent is to give users a variety of choice in which company to register. To initially test the system, on Sept. 19, 2012, the Office of Engineering Technology opened the registration of TVBDs operating in a limited area through certain private companies. Subsequently on Dec. 6, 2012, the OET and WTB approved two of the companies, Spectrum Bridge and Iconnectiv to provide registration and coordination services nationwide. It is interesting to note that Iconnectiv was the once esteemed research and development arm of Bell Labs. Also known as Bellcore, it was responsible for many of the telecom standards still in use today. The company was recently purchased by Ericsson.
The Spectrum Bridge Web portal (whitespaces.spectrumbridge.com/whitespaces/Home.aspx) is straightforward. You can view available white space by entering one of the following location criteria or use an interactive map: Complete address (street, city, state; Zip Code) or latitude, longitude.
The Web portal can also be used to register certain protected devices and services entitled to protection authorized by the FCC rules. These devices and services include: low-power auxiliary stations, including wireless microphones, Multi-Channel Video Programming Distributor (MVPD) receive sites and broadcast auxiliary links (cable headend receive sites).
It also provides apps for both Apple and Android devices, which allow you to identify local white space availability.
Iconnectiv also provides a Web portal (prism.telcordia.com/tvws/main/home/index.shtml) with the ability to view available white space locally and register protected devices. It doesn't appear it has apps for smartphones.
