We design, implement, and evaluate a vehicular communication system that improves uplink
connectivity through multi-lobe beam pattern switching on a smart antenna. Directionality
and base station-diversity are two well-known, independently developed mechanisms for
improving the uplink connectivity of mobile clients. In this paper, we highlight that a system
combining both mechanisms can achieve significant improvement in performance with multi-
lobe beams that strike a tradeoff between directionality and diversity. This is in contrast to the …
