Spatial Multiplexing Capacity Analysis of mmWave WPANs with Directional Antennae

In this paper, we investigate the unique characteristics of millimeter-wave (mmWave) communications and propose an exclusive region (ER) based resource management scheme to explore the spatial multiplexing gain of mm Wave WPANs. We develop an analytical model to study the performance of mm Wave WPANs in terms of the average number of concurrent transmissions and the spatial multiplexing capacity, considering the use of omni-directional and directional antennae. Extensive simulations are conducted to demonstrate the accuracy of the analytical model and the efficiency of the ER based resource management scheme. The analysis and simulation results should provide important guidelines for future deployment of mm Wave based WPANs. Our findings can also be extended to other wireless communications networks in general.
