WindowsPhoneDaily, through a brilliant bit of deductive reasoning, as concluded the Nokia Lumia 900 will probably use the Gobi 3000 LTE modem, same as the HTC Vivid.
He reasoned that only Qualcommâ€™s S4 processors, which have not even hit the market yet, has built-in LTE, and of course Windows Phone 7 does not support the dual-core processors that go along with it (these are probably the processors RIM are awaiting for also).
That only really leaves the use of an â€œexternalâ€ LTE modem like Qualcomms, coupling MSM8x55 and MDM9x00.
It does however raise concerns. WindowsPhoneDaily writes:
Unfortunately it means that the phones might struggle with battery life just as the Thunderbolt did, which was notorious for its small 1400 mAh battery and resulting 4-5 hour life. But we’re hoping against such poor results as rumors say the Lumia 900 will include a much larger 1830 mAh battery and in general, Windows Phone is typically more efficient than Android in terms of power consumption.
Either way we should know a lot more by next week at CES, and of course we will be there to report about it directly.
