my chief curiosity is will this cause roaming agreements to be formed between Verizon and AT&T and T-Mobile? I realize that Sprint is still out of the loop because they are going the way of WiMax, but in the near future I think we'll be looking at a lot more seamlessness between carriers....roaming agreements mean everyone will have a larger network......this could mean a lot for the overall quality of coverage across the states.....and there also wont be the discrepancy of Sprint roaming on Verizon but Verizon only giving Sprint customers access to its 1xRTT network.....T-Mobile never had access to AT&T's 3G in the first place because of band discrepancies......but when everyone is using the same network and the same frequency.....everyone will have 4G roaming or not.....throttling bandwidth anyone and out of curiosity....is every carrier deploying LTE on 700MhZ?
If AT&T and Verizon forge a roaming agreement, it would only be for data, as that is what Verizon's using LTE for. Verizon has no plans on abandoning CDMA anytime soon. CDMA will remain voice, even though their LTE overlay will have capability for it. Also, Verizon doesn't have plans to play nice with SIM card compatibility. So no easy time unlocking devices for use on other LTE rivals. In fact they want to use embedded SIMs. Anything to keep devices on their network and off AT&T and T-Mobile. All this information I'm mentioning is from a news byte post from a while back when a VZ exec (I believe it was Mr. Lynch) was asked about Verizon's LTE aspirations. As far as whether the other LTE carriers will all be on 700mhz? Haven't heard anything definitive from Blue and Magenta. Edit: This link to a post on HoFo (http://www.howardforums.com/showpost.php?p=12297224&postcount=1) mentions the Yahoo News article I mentioned points from.
Also, keep in mind as 3G is phased out (a long way off, I know), those frequencies will be reused for LTE. Therefore the issue with Tmobile's differing frequencies won't go away.
This strengthens the fact that AT&T and Verizon will always be on top. What are the early pros and cons between LTE and WiMax?
