Re: Actually.. their will never be a Spectrum Apocalypse.. Hmm, interesting take on it. I hadn't considered that. I still wonder why they are content to let the 3G network deliver such atrocious performance. I had hoped it would get better up there when they lit up the 4G network but it hasn't, there are still portions of my commute where the 3G network is virtually unusable. I can even identify the individual base stations that are always congested, and accordingly plan my usage of the network during my lengthy commute to work. If they lit up IS-95/EvDo services on PCS would they be able to reuse some of the equipment (antennas and cabling, if nothing else) for a future LTE deployment? Is an antenna an antenna or does LTE need some special antenna configuration that isn't compatible with other air interfaces?
Another random thought, but if they had the PCS bands lit up, perhaps the network wouldn't have failed us so quickly during the floods last year? They lost a number of low lying base stations, and the remaining ones simply couldn't handle the load. For about three days we had great difficulties using the voice network, it ranged from "try ten times and your call will go through" to "doesn't work at all unless you make your call at 3am", depending on where you were. There were even periods when SMS stopped working. This was a minor inconvenience to me, I stayed dry and have a POTS line, but it was huge problem for the first responders, as well as the people who got displaced.
In that same vein, I've wondered why they didn't kill the EvDo network during the floods, so they'd have an extra channel or two for the voice network. Surely voice services are more important than data during a natural disaster? The EvDo network wasn't usable anyway, but it was still turned up, and I've always wondered why.

Without going into too much detail (I'll do that later), LTE antennas...and the radios behind them...are configured quite differently (ideally) than legacy CDMA gear. Look up Remote Radio Heads to see what I'm talking about.
As for why they didn't kill EvDO in favor of voice, I'm pretty sure that an EvDO line card can't do 1x, and vice versa.
said by iansltx:Right, but what stops them from just shutting down EvDO and reassigning the channel to voice service? Would it be a limitation of the 1x line cards, they can only handle so many simultaneous channels or some such?
I'm pretty sure that an EvDO line card can't do 1x, and vice versa.
Mostly idle curiosity on my part, but seeing the failure of the cellular network did reinforce my belief that POTS is worth the $0.80/day it costs.
Probably lack of available line cards.
