1. A method of communicating using a repeater antenna assembly, comprising:
- automatically adjusting a gain of the repeater antenna assembly based upon a pathloss associated with the repeater antenna assembly; and
automatically setting the gain to no more than a highest possible gain that avoids base station desensitization, wherein setting the gain comprises keeping a ratio of the gain to a net pathloss between the repeater antenna assembly and the base station less than an inverse of a noise factor of the repeater antenna assembly.

Abstract
A wireless communication system includes at least one repeater antenna assembly for providing adequate RF coverage within a building, such as a home. An example repeater antenna assembly has an automatically adjustable gain that is controlled responsive to a pathloss associated with a received signal to avoid base station transceiver desensitization and positive feedback. A disclosed assembly avoids base station desensitization and positive feedback. Another disclosed technique maintains a selected minimum link budget within the building.

13. A repeater antenna assembly, comprising:
-
a first antenna; a second antenna; a coupler for coupling the first and second antennas, the coupler having an automated gain adjustor that automatically adjusts a gain of the assembly responsive to a pathloss associated with the first antenna, the automated gain adjuster adjusting the gain of the assembly to no more than a highest possible gain that avoids base station desensitization, wherein the automated gain adjuster automatically sets the gain to no more than the highest possible gain that avoids base station desensitization by keeping a ratio of the gain of the assembly to a net pathloss between the assembly and the base station less than an inverse of a noise factor of the assembly. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
