662.02.4 Radio Interconnect System, Television Broadcast Radio (TVBR). TVBRs

are unlicensed radios designed to produce, tr ansmit, and/or receive radio communication signals at select geographical locations. These radios transmit on available channels in the broadcast television frequency band. The TVBRs shall be proposed on project plans and drawings in geographical locations lacking visual line-of-sight transmission between the proposed transmitting and receiving devices. These devices shall provide partial line-of- sight (LOS) and/or non-line-of-sight (NLOS) radio transmission to establish network communication in areas with obstacles obstructing LOS wireless communication. The TVBRs operate under the Federal Communications Commission (FCC) approved white space TV band database. Each TVBR sh all determine the available TV channels it can operate on before it will be functional for typical usage. The TVBRs retrieve a list of available channels via an Internet connec tion from the white space TV band database dependent on the TVBRs specific geographic coordinates, which are acquired and saved on the device during configuration. Typically, TVBRs can transmit and receive radio communication on six (6) MHz channels. TV Channels 14-36 and 38-51 are available for TVBRs operating on TV channels in the UHF frequency range (470-698 MHz). Once a TVBR is registered with the wh ite space TV band database and associated with a specified operating channel, the channel is removed from the list of available channels. The Contractor shall be responsible for determining the availability of TV bands in the geographical areas for all TVBRs proposed. The Contractor shall provide a list of available TV channels in the UHF frequency range to the Project Engineer, or approved designee. The Contractor shall not procure, purchase, furnish, or install TVBRs or any related equipment without the consent of the Project Engineer or the approved designee without first receiving confirmation from the Project Engineer or th eir designee that verification has been made that the specified channels ar e available in all geographic location(s) for each proposed TVBR site.
