^1The distance separation requirements are not applicable in these
cities until further order from the Commission.
(d) Wireless video assist devices are limited to a maximum of 250
milliwatts ERP and must limit power to that necessary to reliably
receive a signal at a distance of 300 meters. Wireless video assist
devices must comply with the emission limitations of § 74.637.
(e) The antenna of a wireless video assist device must be attached to
the transmitter either permanently, or by means of a unique connector
designed to allow replacement of authorized antennas but prevent the
use of unauthorized antennas. When transmitting, the antenna must not
be more that 10 meters above ground level.
(f)(1) A license for a wireless video assist device will authorize the
license holder to use all frequencies available for wireless video
assist devices, subject to the limitations specified in this section.
(2) Licensees may operate as many wireless video assist devices as
necessary, subject to the notification procedures of this section.
(g) Notification procedure. Prior to the commencement of transmitting,
licensees must notify the local broadcasting coordinator of their
intent to transmit. If there is no local coordinator in the intended
area of operation, licensees must notify all adjacent channel TV
stations within 161 km (100 mi) of the proposed operating area.
(1) Notification must be made at least 10 working days prior to the
date of intended transmission.
(2) Notifications must include:
(i) Frequency or frequencies.
(iii) Antenna height.
(iv) Emission type(s).
(v) Effective radiated power.
(vi) Intended dates of operation.
(vii) Licensee contact information.
(3)(i) Failure of a local coordinator to respond to a notification
request prior to the intended dates of operation indicated on the
request will be considered as having the approval of the coordinator.
In this case, licensees must in addition notify all co-channel and
adjacent channel TV stations within 161 km (100 mi) of the proposed
operating area. This notification is for information purposes only and
will not enable TV stations to prevent a WAVD from operating, but is
intended to help identify the source of interference if any is
experienced after a WAVD begins operation.
(ii) If there is no local coordinator in the intended area of
operation, failure of any adjacent channel TV station to respond to a
notification request prior to the intended dates of operation indicated
on the request will be considered as having the approval of the TV
(4) Licensees must operate in a manner consistent with the response of
the local coordinator, or, if there is no local coordinator in the
intended area of operation, the responses of the adjacent channel TV
stations. Disagreements may be appealed to the Commission. However, in
those instances, the licensee will bear the burden of proof and
proceeding to overturn the recommendation of the local coordinator or
the co-channel or adjacent channel TV station.
(h) Licenses for wireless video assist devices may not be transferred
(i) Operations in 600 MHz band assigned to wireless licensees under
part 27 of this chapter. A wireless video assist device that operates
on frequencies in the 600 MHz band assigned to wireless licensees under
part 27of this chapter must cease operations on those frequencies no
later than the end of the post-auction transition period as defined in
§ 27.4 of this chapter. During the post-auction transition period,
wireless video assist devices will operate on a secondary basis to
licensees of part 27 of this chapter, i.e., they must not cause to and
must accept harmful interference from these licensees.
