If you deviate from the standard, you lose the advantage of the standard. At that point, why not just keep rolling proprietary, just improved?

They can cut over from WiMax to LTE with just firmware and there is no reason not to deviate since the PHY doesn’t have to be compatible with anything else.

Being SDR, I suppose they theoretically could, I just haven't seen it happen yet. Presumably the CPE are built around a standards based chipset, so it would probably mean an increase in price for those as well.

That’s manufacturer dependent since they aren’t locked to the full cellular PHY.

This is a big downside to this gear IMO. If someone would optimize LTE for use in a fixed environment you could possibly get better latency, but I'm not seeing that happening.

Throughput, Sync, Interference, spectrum efficiency, cost etc? What I really wander is can you bond two non adjacent 10MHZ channels with Telrad to make a 20MHZ channel? I know you cannot with 450 and it might become very useful down the road. Right now with 450 and a perfect connection on a 20MHZ channel we can do around 80Mbps downstream per sector. With a 10MHZ channel and not so perfect connections that is really getting cut back. Also, right now we can do ABAB quite easily with 450 gear. With LTE can we do AAAA where spectrum is scarce?
