clarity:
No, Airport and Bluetooth are separate but yes, the Airport standard does come in higher ranges. Orinoco makes a building-mount kit with horizon-reaching range.
Keep in mind: speed isn't about a given device's rated transfer capacity but on the functioning bandwidth per user of the local and wide area networks. Airport has a rather funky-cool feature in routing data between multiple base-stations in a large network to "even out" Bandwidth. It's not widely published or understood but it's something about how it packets data. If I'm moving Data from Germany to California it passes through a bottleneck at (say) Frankfurt, at the Channel, At the Atlantic Fiber, at the fiber-local ARPA, at the ARPA at my end AND at my ISP. All this reduces the data transfer rate as millions of other users, systems, networks etc. do the same thing through the same few high-end gateways. If large areas were layed out using Airport tech to supplement existing infrastructure the data-saturation capacity would go up nearly exponentially just in more even distribution. I.E. if you get a consistant better-than-airport speed You're a lucky pudd.
Bluetooth compatibility is aimed more at devices and peripherals, it would be cool to see the two on the same tranciever though........
