Using a Coaxial Cable for Distributing MIMO Signals In-house
First Claim
1. A method for using spatial multiplexing in conjunction with a coaxial cable deployed in-house, comprising:
- converting a plurality of input streams associated with spatial multiplexing, respectively, into a plurality of signals occupying, respectively, a plurality of different frequencies;
transporting the plurality of signals, via a coaxial cable deployed in-house, into a certain room located in-house, thereby enabling a presence of the plurality of signals in the certain room;
shifting the plurality of signals into, respectively, a plurality of output signals, in which all said output signals occupy a single wireless frequency, and in which said shifting is achieved by up-converting each one of the signals, which are now present in the certain room, from the corresponding one of the different frequencies into the single wireless frequency; and
transmitting wirelessly, using only the single wireless frequency, the plurality of output signals via a plurality of respective antennas located in the certain room, all said antennas operating in conjunction with the single wireless frequency, thereby achieving spatial multiplexing in the certain room and in conjunction with the coaxial cable.

Abstract
Systems and methods for using spatial multiplexing in conjunction with a coaxial cable deployed in-house. Input streams associated with spatial multiplexing are converted into respective signals occupying different respective frequencies. The signals are transported, via a coaxial cable deployed in-house, into a certain room located in-house, thereby enabling a presence of the plurality of signals in the certain room. The signals are shifted into respective output signals that occupy a single wireless frequency by up-converting each signal from the corresponding different frequency into the single wireless frequency. The output signals are transmitted wirelessly, using only the single wireless frequency, via respective antennas located in the certain room, all said antennas operating in conjunction with the single wireless frequency, thereby achieving spatial multiplexing in the certain room and in conjunction with the coaxial cable.
