Yeah too bad... initially I thought the LTE Evo was gonna be great as far as compatibility. Since some phones can change frequencies when switching cell tower sites multiple radios would make the phone a beast. I'm sad to say the phone won't even support the (down the line) future 800mhz LTE frequency!
Sprint will at some point use that spectrum when they have enough money to accomidate current towers. This phone isn't capable of 800mhz at all, it uses the 1900mhz spectrum which is essentially the old iden network (walkie talkie services) which the carrier is re-using for fast LTE rollout purposes. Now currently wimax is working on the 2500-2600mhz spectrum which isn't listed at all in the phone filing, bummer but wimax be gone already that was big mistake.
It' fine since it'll be at least 2 years before we get to use the better 800mhz spectrum, but to not ever be compatible at all? I dunno. The 1900mhz spectrum is ok as long as you don't need alot of building penetration and all but I guess wimax is worse at 2500-2600 so if wimax held up well I guess 1900 would be a small improvement. Just a shame they're tooting the LTE horn and in the background hiding the fact that their long term plans include the 800mhz spectrum and their first LTE phone won't even support it... EVER!
