Measurements were taken during PCS 1900 field trials to quantify the difference in two branch diversity improvement between conventional space diversity of >10 wavelengths spacing and horizontal/vertical polarization diversity at cell sites in the MCI test systems in Richardson, Texas and Washington, DC. Data was taken with both the mobile unit antenna vertical, and with the mobile antenna tilted 45 degrees to the vertical to simulate the typical operating position of a handheld subscriber terminal. A simple evaluation method, using the inherent monitoring facilities contained within the GSM signal format, was developed and used during testing. Under conditions representative of handheld operation, results indicate that base station receiver polarization diversity provided an attractive alternative to space diversity.>
