Regulation 7 Anti-oscillation requirementsI1

The mobile repeater device must—

Any oscillations in the uplink frequencies must be detected within 0.3 seconds.

Any oscillations in the downlink frequencies must be detected within one second.

Subject to paragraph (5), if the mobile repeater device detects any oscillations, it must use an anti-oscillation technique which stops those oscillations and continues for at least one minute.

If an anti-oscillation technique has been used on five occasions in accordance with paragraph (4), and the mobile repeater device subsequently detects further oscillations, it must cease transmitting.

A mobile repeater device which has ceased transmitting in accordance with paragraph (5) must only resume operation if it has been manually reset.

For the purpose of this regulation, a mobile repeater device makes oscillations when the transmissions made by the mobile repeater device are received and subsequently re-amplified by that device, resulting in a fluctuation in the transmit power of that device (either in the frequency band being amplified or in another frequency band).
