Spatial Data Focusing is implemented using Direct Sequence Spread Spectrum technique with orthogonal Gold code sequences forming the orthogonal transmit signal basis. IQ resources are used to facilitate additional degree of freedom. With a four element antenna array, it is demonstrated that this scheme attains a beam-width of less than $4^\circ$. The robustness of this schemes' performance is assessed using a 6-ray urban canyon multipath micro-cell channel model simulation. (In SDF, the beamwidth is defined as the region within which transmitted signals can be decoded
