§ 15.611 General technical requirements.
(a) Conducted emission limits. Access BPL is not subject to the
conducted emission limits of § 15.107.
(b) Radiated emission limits --(1) Medium voltage power lines. (i)
Access BPL systems that operate in the frequency range of 1.705 kHz to
30 MHz over medium voltage power lines shall comply with the radiated
emission limits for intentional radiators provided in § 15.209.
(ii) Access BPL systems that operate in the frequency range above 30
MHz over medium voltage power lines shall comply with the radiated
emission limits provided in § 15.109(b).
(2) Low voltage power lines. Access BPL systems that operate over
low-voltage power lines, including those that operate over low-voltage
lines that are connected to the in-building wiring, shall comply with
the radiated emission limits provided in § 15.109(a) and (e).
(c) Interference Mitigation and Avoidance. (1) Access BPL systems shall
incorporate adaptive interference mitigation techniques to remotely
reduce power and adjust operating frequencies, in order to avoid
site-specific, local use of the same spectrum by licensed services.
These techniques may include adaptive or "notch" filtering, or complete
avoidance of frequencies, or bands of frequencies, locally used by
licensed radio operations.
(i) For frequencies below 30 MHz, when a notch filter is used to avoid
interference to a specific frequency band, the Access BPL system shall
be capable of attenuating emissions within that band to a level at
least 20 dB below the applicable part 15 limits.
(ii) For frequencies above 30 MHz, when a notch filter is used to avoid
interference to a specific frequency band, the Access BPL system shall
be capable of attenuating emissions within that band to a level at
least 10 dB below the applicable part 15 limits.
(iii) At locations where an Access BPL operator attenuates radiated
emissions from its operations in accordance with the above required
capabilities, we will not require that operator to take further actions
to resolve complaints of harmful interference to mobile operations.
(2) Access BPL systems shall comply with applicable radiated emission
limits upon power-up following a fault condition, or during a start-up
operation after a shut-off procedure, by the use of a non-volatile
memory, or some other method, to immediately restore previous settings
with programmed notches and excluded bands, to avoid time delay caused
by the need for manual re-programming during which protected services
may be vulnerable.
(3) Access BPL systems shall incorporate a remote-controllable
shut-down feature to deactivate, from a central location, any unit
found to cause harmful interference, if other interference mitigation
techniques do not resolve the interference problem.
