Probably because they have some not-so-critical application that requires high bandwidth burst data (downloading tiled bitmap maps comes to mind), which is not something that you can do on VHF bands with currently available off the shelf technology (not to mention that the spectrum allocation certainly constrains emission types in such way that doing things like wideband MIMO COFDM and other high processing gain modulations is explicitly forbidden)
