[http://imcellular.wordpress.com/2008/11/19/wi-fi-appearing-in-smartphones/] 11 of the top 15 smartphones recently reviewed by PC Magazine include Wi-Fi! I suspect that there are many motivations, not the least being that operators recognize that the free use of Wi-Fi greatly reduces the burden on their networks, and they foresee an explosion in data use: I've seen forecasts of 1000% traffic increase in 5 years). With traffic increasing 1000% and revenues increasing 100%, the operators are in a bind. Hence the desire to offload on Wi-Fi and--even better for Operators--Femtocell.

With the requirement to drive multiple radios, providing 802.11n in a battery-powered device will be a challenge. The Wi-Fi Alliance has proposed an n-capable interface for voice devices that will use a single transmit chain, and hence, one radio. The advantage of this approach is somewhat in question, because with a single transmit chain, 802.11n doesn't provide much more capacity than 802.11a or g.
