The performance of a radio link for indoor communications at 29 GHz
This paper focuses on the design of an indoor broadband radio system at 29 GHz with some emphasis on the effect of antennas on the availability of the system, for various cell sizes. The system has a maximum information bit rate of 155 Mb/sec and a maximum receiver noise figure of 8 dB. Channel measurements with antenna diversity were carried out during an earlier stage of the project at 2L6 GHz and 37.2 GHz. The resulting characterization provided knowledge of the parameters needed to evaluate the performance of the link. These included large-scale path-loss models which gave estimates of the power-law exponents and statistics of the received envelope. Transceiver characteristics and measured channel behavior as outlined above along with the different antenna types (omnidirectional and horn) and different antenna orientations determine the distribution of the received power across the cell, and thus the average availability. Practical configurations were investigated involving partial alignment or no alignment of the base station and portable antennas. Full antenna alignment was also examined for the purpose of comparison.
