Looking through testing documentation at the FCC, ExtremeTech's Neal Gompa found that the AT&T version of the iPhone 5 supports LTE on two unlisted bands: cellular and PCS. Those bands are currently used for the operators 2G and 3G networks.
GigaOm suggests that AT&T may be planning a massive overhaul of their network onto these bands.
It's puzzling that the new iPhone supports those frequencies today. European operators are a year away from having sizable LTE network on their 2.6 GHz spectrum, yet Apple nixed those frequencies from all its iPhones. Why would it make cellular and PCS such big exceptions?
Either AT&T has enormous pull with Apple, convincing to make an iPhone that work on networks years away from being deployed. Or AT&T is planning a massive reconfiguration of its networks in the next year, something akin to the major network overhaul T-Mobile is doing today.
What do you think? Could AT&T be planning to cannibalize its 2G and 3G networks to for LTE.
