Abstract

A wireless repeater having dual cancellation loops is presented. A first cancellation loop is configured to remove an undesirable signal resulting from a design or manufacture of the repeater. A second cancellation is configured remove undesirable signals cause by a real-time changing environment where the repeater is deployed.

Claims

1. A wireless repeater comprising

a first and a second antenna;

a first cancellation loop coupled to the first and the second antenna;

a second cancellation loop coupled to the first and the second antenna; and

wherein the first and the second cancellation loops allow for placing the antennas relative to each other irrespective of gain.

2. The repeater of claim 1, further comprising a bi-directional amplifier coupling the first and the second antenna.

3. The repeater of claim 1, wherein the first loop is configured to cancel a leak signal.

4. The repeater of claim 1, wherein the second loop is configured to cancel an environmentally induced signal.

5. The repeater of claim 4, wherein the second loop is configured to adapt in real-time to environmental conditions.
