1. A repeater, comprising one or more processors and memory configured to:
- identify first power levels for a plurality of sub-bands included in a defined passband, wherein the repeater is configured to amplify signals on frequencies within the defined passband in accordance with an amplification level;
identify second power levels for the plurality of sub-bands included in the defined passband after the amplification level is adjusted by a predetermined amount;
compare the first power levels with the second power levels to determine whether or not the repeater is approaching an oscillation; and
modify the amplification level depending on whether the repeater is approaching the oscillation or not approaching the oscillation.

Abstract
Technology for a repeater is disclosed. The repeater can measure a first power level within a passband. The repeater can adjust a gain of the repeater by a selected amount. The repeater can measure a second power level within the passband. The repeater can calculate a difference between the first power level and the second power level. The repeater can determine that the repeater is approaching an oscillation when the difference is different than a selected amount by a predetermined threshold.

12. A repeater, comprising:
-
a narrowband detector operable to detect power levels for a plurality of sub-bands included in a defined passband, wherein the repeater is configured to amplify signals on frequencies within the defined passband in accordance with an amplification level; and a controller configured to; compare the detected power levels with baseline power levels to determine whether or not the repeater is approaching an oscillation; and modify the amplification level depending on whether the repeater is approaching the oscillation or not approaching the oscillation. - View Dependent Claims (13, 14, 15, 16, 17)
