The enormous success of advanced wireless devices is pushing the demand for higher wireless data rates. The industry is satisfying this increasing demand by densely deploying large numbers of access points (APs). Unfortunately, unicast rates, especially in crowded scenarios, remain very low due to severe interference and time-sharing. However, one may take advantage of the broadcasting nature of wireless transmissions to offer high multicast rates. Motivated by this, we present coordinated broadcasting (Co-BCast), a system which coordinates multiple APs to provide participants of big events with high multicast rates that can support multiple high definition video streams.
