Three things.

chipsets lack support for ibss mode in 802.11a

8 non-overlapping indoor channels in north america, makes the 802.11a 
radio noise situation more tractable. From a deployment perspective the 
map coloring problem is much easier.

All things being equal an a card has signficantly shorter range range at 
5.8ghz than a b card does at 2412ghz, and more surfaces (airwalls people 
etc) are opaque. This cuts down on the noise quite a bit.
