Smart antennas can be useful in significantly increasing the capacity of wireless ad hoc networks. A number of media access and routing protocols have been recently proposed for the use with such antennas, and have shown significant performance improvements over the omnidirectional case. However, none of these works explores if and how different directional and smart antenna designs affect the asymptotic capacity bounds, derived by the researchers. These bounds are inherent to specific ad-hoc network characteristics, like the shared wireless media and multi-hop connectivity, and pose major scalability limitations for such networks.
