1. A wireless repeater comprising:
- a watermarking module to selectively apply or not apply a watermark to at least one channel in a repeater operating band based, at least in part, on a control signal; and
a receiver to receive a wireless transmission, to determine a type of an airlink corresponding to at least a portion of the wireless transmission based on demodulating a signal in the portion of the wireless transmission using one of a plurality of demodulation configurations, and to generate the control signal based, at least in part, on the type of the airlink.

Abstract
A wireless repeater configured for implementation in a wireless communication system is disclosed. The repeater can be configured to receive and rebroadcast communications using various types of airlinks in a wireless communication system. The wireless repeater can include a receiver configured to sense the type of airlink being supported by the repeater. The repeater can then selectively apply a repeater identifying watermark to a signal based on the type of airlink. The repeater may be configured to periodically scan an operating bandwidth for supported airlinks and can configure the watermarking applied to signals within the channels based on the detected airlinks.
