WiMAX in the US is still ahead
Clearwire/Sprint have really started the roll-out of 4G WiMAX in the Colonies here. I've gotten excellent performance (as it should be with a still-nascent customer base) - equivalent to or better than DOCSIS cable. Latency is the same as 3G, but once the pause is over, web pages load lickety-split.
Here in the States the marketplace is going to be a bit more interesting. With AT&T suffering from iPhone overload and neither Verizon or T-Mobile moving very quickly on LTE, WiMAX has a good chance of establishing a foothold against the GSM competition.
Of course, Sprint has got both guns out and is blazing away at its feet: currently there is an authentication "glitch" that prohibits anything but a PC running Windows of OS-X from connecting to the Sprint-managed WiMAX network. Sprint is giving away free Cradlepoint PHS300 wireless 3G/4G routers with the Franklin U300 WiMAX/3G modem...but these will only connect to 3G on Sprint right now. (They work 4G with Clearwire however.)
Is this a technical glitch, or Evil Sprint knowing that, with a 4G plan that restricts 3G to only 5GB before draconian overage charges kick in, they can suck some extra revenue from the punters? Given that Sprint is demonstrating 4G in the stores using the PHS300 - plainly flashing the green LED of "3G-only" service - it really makes you wonder.
