System and method for determining repeater gain

An apparatus for repeating signals in a wireless communication network, comprising

• a first antenna;
• a transmitter operable to transmit signals on the first antenna;
• a second antenna;
• a receiver operable to receive signals through the second antenna;
• and
• a processor operable to:
• transmit a sequence of bits over the first antenna using the transmitter;
• measure an attenuation in the transmitted bits as received at the second antenna;
• determine a power value based on the attenuation, wherein the processor is operable to determine the power value by:
• calculating an isolation value based on the attenuation;
• transmitting the isolation value to a base station using the transmitter, and
• receiving the power value from the base station;
• receive information at a first power level from one of a mobile terminal and a base station;
• determine, based at least in part on the power value, a second power level at which to transmit the received information;
• and
• transmit the received information at the second power level.

A method for operating a repeater in a wireless communication network, comprising

• transmitting a predetermined sequence of bits over a first antenna of a repeater;
• measuring an attenuation in the transmitted bits as received at a second antenna of the repeater;
• determining a power value for the repeater based on the attenuation, wherein determining the power value for the repeater comprises determining a gain level for the repeater, by calculating an isolation value for the repeater that is proportional to the attenuation and determining the gain level such that a product of the gain level and the isolation value is less than a predetermined maximum;
• receiving information at a first power level from one of a mobile terminal and a base station;
• determining, based at least in part on the power value, a second power level at which to transmit the received information;
• and
• transmitting the received information at the second power level.
