Abstract

A wireless signal repeater having an integrated display that concurrently displays a receive signal level, a transmit signal level, and a textual indication of signal quality, reflecting how well the repeater is currently operating to repeat wireless signals. By reference to the integrated display, a user can readily determine whether the repeater is well positioned to function as desired. And if the display indicates that the repeater is not functioning optimally, the user can then conveniently move the repeater around until the repeater reflects an acceptable level of operation.
