I got enough questions on this matter that I decided to expand upon it via a new Farpoint Group Tech Note, which you can find here. Let me know what you think. Even the cellular guys, still depreciating their 3G infrastructures, will eventually go the open-access route, if for no other reason than there's a lot more money to be made going open and all-IP than with Bell-System-era thinking. [Ed note: In fact, this seems to be happening faster than you might have thought.] Carriers, after all, need to get the most out of the billions that will go into the next and subsequent spectrum auctions, and open-access is the best way to maximize ROI.
