Executive Summary

The IEEE 802.11p standard has been optimized for low-delay small-bandwidth wireless communications to provide vehicular safety services. However, IEEE 802.11p transceivers can considerably improve their robustness by incorporating MIMO transmission methods. Moreover, multiple antennas can also be used to increase the data transfer rate of IEEE 802.11p transceivers, a requirement necessary to implement, for instance, non-critical safety applications. In this paper, the authors describe the design and development of a multiple-antenna IEEE 802.11p performance evaluation system made of two IEEE 802.11p software-based transceivers and two different, flexible low-cost FPGA-based multi-antenna channel emulators.
