Smart targetable antenna array (STA) technology has been developing over the past few years. The things needed to make it feasible for mass market applications are low cost, small size (to fit portable device form factors), and low cost circuitry to drive the arrays and process the data. In addition to targetable arrays, a related area should also prove advantageous: phase, vector/spatial, and time domain signal differentiation. These are methods to differentiate the signals to reduce problems with multi-path interference and increase range and signal efficiency and reliability. The techniques are already being used in a few commercial wireless systems, some with unlicensed spectrum applications including WiFi. However, they have not yet been scaled to similar form factors as expected with the new planar array antenna technologies . . but that will happen. Over the next five years the gains made in bits per hertz due to advanced modulation schemes including W-OFDM/TDD/FDD/OFDMA will be substantial. The gains made through 'spectrum reuse' with STA and signal differentiation combined with MIMO and multi-threaded DSP will be many times greater. Current designs make it feasible to achieve real world spectrum reuse of about 10X. Theoretical limits are at least 100X.
