How does this work?
Sprint-Nextel and AT&T use different technologies for their cell networks. How can they share networks in particular markets? Am I missing something?
They may use different technologies, but they run the same frequency (850/1900 MHz) Looking at the article mentioning BellSouth, I think the issue is the 850 MHz that Sprint want to roam off of.
I believe this has something to do with the landline exchange system. Usually X company pays Y company for the call routing onto their system. Which is why BellSouth was mentioned.
