Abstract
A wireless network includes at least one Multiple Input Multiple Output (MIMO) wireless network station and two or more physical layer repeaters. Each of the physical layer repeaters is for receiving a wireless signal to or from the at least one MIMO wireless network station and re-transmitting the wireless signal while continuing to receive the wireless signal. The repeaters may be either frequency translating repeaters or non-frequency translating repeaters.

9. A time division duplex (TDD) wireless repeater configuration, comprising:
-
a first TDD wireless repeater capable of recognizing that it is operating in a Multiple Input Multiple Output (MIMO) wireless network;
a second TDD wireless repeater spatially separated from the first TDD wireless repeater;
wherein the first TDD wireless repeater is capable of identifying a presence of the second TDD wireless repeater, entering into a mode with the second TDD wireless repeater to receive wireless transmissions in a synchronous manner with the second TDD wireless repeater on a same first frequency, and of re-transmitting the wireless transmissions in a manner that is synchronous with the second TDD wireless repeater on a same second frequency. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A time division duplex (TDD) wireless repeater configuration, comprising:
-
a first TDD wireless repeater capable of detecting transmissions from Multiple Input Multiple Output (MIMO) enabled devices in a wireless network;
a second TDD wireless repeater also capable of detecting the transmissions from the MIMO enabled devices;
wherein the first TDD wireless repeater and the second TDD wireless repeater begin to re-transmit in a synchronous mode with one another upon at least one of the first TDD wireless repeater and the second TDD wireless repeater detecting the transmissions from the MIMO enabled devices.

19. A time division duplex (TDD) wireless repeater configuration, comprising:
-
a first TDD wireless repeater capable of detecting transmissions from Multiple Input Multiple Output (MIMO) enabled devices in a wireless network;
a second TDD wireless repeater also capable of detecting the transmissions from the MIMO enabled devices;
wherein;
the first TDD wireless repeater and the second TDD wireless repeater begin to re-transmit in a synchronous mode with one another upon at least one of the first TDD wireless repeater and the second TDD wireless repeater detecting the transmissions from the MIMO enabled devices; and
the first TDD wireless repeater and the second TDD wireless repeater configured to;
detect a frequency offset between a frequency associated with the detected transmissions and a respective local frequency reference; and
compensate for the frequency offset by adjusting the local frequency reference to reduce the frequency offset. - View Dependent Claims (20, 21, 22)
