Marking the end of a remarkable era in cellular technology, the FCC is officially letting American carriers decommission their legacy analog networks as of today, February 18, 2008. Few of us still own a phone based on AMPS -- Advanced Mobile Phone System, ironically, despite the fact that there's been nothing "advanced" about it for many years -- but we owe the very existence of the world's modern wireless infrastructure to the introduction and overwhelming success of the Bell Labs-developed technology. So successful was AMPS, in fact, that it eventually covered virtually 100 percent of the continental United States, a statistic CDMA and GSM have only recently begun to approach.

In a wrap-up of the state of 4G networks over at BusinessWeek, the battle between the three competing 4G network standards -- WIMAX, Long Term Evolution (LTE), and Ultra Mobile Broadband (UMB) -- is appraised, with WIMAX clearly edging out its other rivals. This could be a two horse race before long if Verizon chooses to back GSM's successor LTE over CDMA's sequel, UMB. That would leave Qualcomm without one of its most significant backers for CDMA's spiritual sibling, although it'll do just fine thanks to the multiple 4G patents it holds. Ultimately though, in all of this space there's very little discussion about what the consumer wants: do we really need two or three different standards that probably won't inter-operate, leaving us back at the square we've always been at? Frankly, for all the benefits that 4G is purported to bring, we'd like something a little more imaginative than the usual bickering amongst the big shots.

Update: Although it didn't come from VZW, last month Vodafone's chairman Arun Sarin made it clear that Verizon will go for LTE. Bad news for UMB!
