Ultra Mobile Broadband specifications get published
Not quite a year after EV-DO Rev. C became more commonly known as Ultra Mobile Broadband, we're now hearing that the official specifications have been published. Reportedly, the UMB specification should be "quickly converted into an official global standard by the 3GPP2 organizational partners," and with it should come "peak download data rates of 288Mbps in a 20MHz bandwidth." Notably, the release states that multi-mode, multi-band UMB devices will "leverage the existing 3G CDMA device selection to preserve economies of scale," and it's scheduled to become widely available on a worldwide basis during the first half of 2009.[Via RCRWirelessNews]

Yep, so?
SK Telecom and KTF (the # 1 and #2 Korean mobile providers) both launched HSDPA...
'au' may choose UMB but who the hell cares as their flavour of CDMA has reversed Tx and Rx channels compared to everywhere else on Earth using the 800Mhz band and they also DO NOT use ESN, MEID, or IMEI numbers - opting instead for a Japan only serial number system - making their handsets completely incompatible with any other provider on Earth.
UMB is looking like it will be a still born baby with most of the worlds largest CDMA2000 players abandoning the technology.
