A TVBD must incorporate spectrum sensing capabilities that can detect TV and wireless microphone signals. A TVBD must have the capabilityto displaya list of identified available channels and its operating channel. A TVBD must comply with the RF safety requirements of Section 15.709(d). Out-of-band emissions must complywith the limits in Section 15.709(c). The instruction manual must contain the statement shown in Section 15.706(a) that advises of the potential for a TVBD to cause interference to TV reception and lists possible measures to correct any interference that does occur. 8.What are the requirementsthat apply to fixed TVBDs?

  • A description of the transmit power control mechanism must be submitted with the application for certification. For general information about the certification process for TVBDs, see Sections 13 and 17 below. A TVBD must have the capability to display a list of identified available channels and its operating channel. A TVBD must comply with the RF safety requirements of Section 15.709(d). In-band power must comply with the limits in Section 15.709(a). Out-of-band emissions must comply with the limits in Section 15.709(c). The conducted power spectral density at the antenna must comply with the limits in Section 15.709(a)(5). A TVBD must be labeled with an FCC identification number as required by Section 2.925 and the statement required by Section 15.19(a)(3) indicating that

  • word ``device'' after ``TVBD'' and adding the phrase ``...of this part...'' after ``15.101(b)''. Section 15.707(a) is corrected by removing the word ``available'' and adding the phrase ``...that is available at all locations within the protection range of the coordinates of each such area as set forth in section 15.712(d) of this part.'' at the end of the first sentence. Section 15.709(b)(3) is corrected by replacing the phrase ``...the receive antenna used for...'' with the phrase ``...an antenna used for transmission, reception and...'' Section 15.709(b)(4) is added to state ``For both fixed and personal/portable TVBDs with a separate sensing antenna, compliance testing shall be performed using the lowest gain antenna for each type of antenna to be certified.'' Section 15.709(c)(1) is corrected

The last sentence of paragraph 83 of the text of the MO&O is corrected to read: We are also clarifying that a device that operates across more than one 6 MHz TV channel is still subject to the maximum power limits in Sections 15.709(a)(1) and (a)(2) of the rules per channel - the allowable power per channel does not increase with use of additional bandwidth beyond 6 megahertz. The last sentence of paragraph 87 of the text of the MO&O is corrected to read: Thus, we are revising the required adjacent channel attenuation to be 72.8 dB.

  • MHz, 76 - 88 MHz, 174 - 216 MHz, 470 - 608 MHz and 614 - 698 MHz bands. Section 15.703 Definitions. Available Channel. A television channel which is not being used by an authorized user at or near the same geographic location as the TVBD and is acceptable for use by an unlicensed device under the provisions of Section 15.709 of this chapter. A TVBD determines television channel availability either from the TV bands database or Spectrum Sensing. Client Device. A TVBD operating in Client Mode. Client Mode. An operating mode in which the transmissions of the TVBD, including frequencies of operation, are under control of the Master Device. A device in client mode is not able to initiate a

Specifically, Section 15.709(c) does not specify whether compliance with the adjacent channel emission limits is determined through radiated or conducted measurements. In addition, Section 15.709(a)(5) requires measurement of the power conducted from the TV bands device into the antenna to determine compliance with the PSD limits. However, this is not possible for personal/portable devices which are required to have a permanently attached antenna.
