Abstract

Results of experiments using a variety of antennas inside several buildings are presented. Path loss models for the 1.3 GHz and 4.0 GHz bands that show little difference in indoor path loss throughout the low-microwave region are discussed. Results show that line-of-sight (LOS) channels offer significantly more cross-polarization discrimination than obstructed (OBS) channels. A profound result is that directional circularly polarized (CP) antennas always reduce rms delay spread when compared to omnidirectional and directional linearly polarized (LP) antennas in LOS. The variation of rms delay spread as a mobile moves over several wavelengths is also greatly reduced when CP antennas are used.
