The invention is directed to a method and system for supporting MIMO technologies' which can require the transport of multiple spatial streams on a traditional Distributed Antenna System (DAS) (100). According to the invention, at one end of the DAS, each spatial stream is shifted in frequency to a pre-assigned band (such as a band at a frequency lower than the native frequency) that does not overlap the band assigned tp other spatial streams (or the band of any other services being carried by the DAS). Each- of the spatial streams can be combined and transmitted as a combined signal over a common coaxial cable (140). At the other "end" of the DAS, the different streams are shifted back to their original (overlapping) frequencies but retain their individual "identities" by being radiated through physically separate antenna elements (164a, 166a).
