This paper presents results of a tri-polarized multiple-input multiple-output (MIMO) channel measurement campaign in typical room-room and floor-floor micro-cellular environments. By implementing the MIMO channels in the polarization rather than conventional spatial domain, we are able to co-locate the antenna elements at both ends of the communications link. This results in a compact system that would be a good candidate for future designs of mobile communications systems including handsets. Benchmarking against the spatial technique, demonstrates that a polarized MIMO system can offer approximately the same 10% outage capacity. In terms of ergodic capacity, the tri-polar outperforms the spatial technique by up to 2 b/s/Hz.
