1. A system comprising:
- a first repeater including;
an amplifier configured to amplify one or more Radio Frequency (RF) communication signals;
a transmission loss detector configured to determine a transmission loss of one or more RF reference signals across a RF wired signal path, wherein frequency bands of the one or more RF reference signals are outside frequency bands of the one or more RF communication signals to permit continuous amplifying the one or more RF communication signals while determining the transmission loss; and
a gain controller configured to adjust a gain or noise power of the amplifier of the first repeater or a second repeater based on the determined transmission loss across the RF wired signal path; and
the second repeater, coupled to the first repeater by the RF wired signal path, the second repeater including;
an amplifier configured to amplify the one or more RF communication signals; and
a signal generator configured to generate the one or more RF reference signals at a predetermined amplitude or power.

Abstract
Technology for multi-amplifier repeaters to offset at least a portion of a determined transmission loss across a RF wired signal path coupled the repeaters, while complying is regulator constraints, is disclosed. A repeater can use an RF reference signal or the RF communication signals to determine the transmission loss across the RF wired signal path, while the repeaters amplify the RF communication signals.

11. A repeater comprising one or more processors and memory configured to:
-
amplify one or more Radio Frequency (RF) communication signals; determine a transmission loss of one or more RF reference signals across a RF wired signal path coupling the repeater to another repeater, wherein frequency bands of the one or more RF reference signals are outside frequency bands of the one or more RF communication signals to permit continuous amplifying the one or more RF communication signals while determining the transmission loss; and adjust a gain or noise power of amplifying the one or more RF communication signals based on the determined transmission loss across the RF wired signal path. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for calibrating a repeater comprising:
-
sensing a signal level at a first repeater of a Radio Frequency (RF) communication signal transmitted from a second repeater to the first repeater on an RF wired signal path; generating, at the second repeater, one or more RF reference signals at a predetermined amplitude or power; receiving, at the first repeater, an indication of a signal level of the RF signal at the second repeater; determining a transmission loss across the RF wired signal path as a function of the signal level of the RF signal at the second repeater and the signal level of the RF signal at the first repeater; determining a transmission loss of the one or more RF reference signals across the RF wired signal path, wherein frequency bands of the one or more RF reference signals are outside frequency bands of the RF communication signal to permit continuous amplifying of the one or more RF communication signals while determining the transmission loss across the RF wired signal path; and adjusting a gain or noise power of the first repeater or the second repeater to compensate for the transmission loss across the RF wired signal path. - View Dependent Claims (18, 19, 20, 21)
