Space diversity usually works best in a mobile network with > 10 wavelengths seperation, with 2 wavelengths being absolue minimum. The plane of the antennae should be oriented at 90 degrees to the direction of desired diversity gain. It doesn't matter what the protocol is, be it GSM, WCDMA, DAPMS etc.
