Multi-mode wireless communication link
First Claim
1. A communication system comprising first and second transmitters, which are coupled to transmit respective first and second Radio Frequency (RF) signals carrying first and second data over a wireless communication channel, to select an operational mode from a group of operational modes and to operate in the selected operational mode, wherein the group of the operational modes comprises at least two of:
- a protection mode, wherein the second transmitter serves as backup to the first transmitter;
a spatial multiplexing mode, in which the first data is different from the second data, and the first and second transmitters transmit simultaneously; and
a beam-forming mode, in which the first data is identical to the second data, the second RF signal comprises a phase-shifted replica of the first RF signal, and the first and second transmitters transmit simultaneously.

Abstract
A communication system includes first and second transmitters, which are coupled to transmit respective first and second Radio Frequency (RF) signals carrying first and second data over a wireless communication channel. The transmitters are coupled to select an operational mode from a group of operational modes and to operate in the selected operational mode. The group of the operational modes includes at least two of a protection mode, wherein the second transmitter serves as backup to the first transmitter, a spatial multiplexing mode, in which the first data is different from the second data and the first and second transmitters transmit simultaneously, and a beam-forming mode, in which the first data is identical to the second data, the second RF signal includes a phase-shifted replica of the first RF signal, and the first and second transmitters transmit simultaneously.
