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

That’s just it, it’s not built around a standard chipset. 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.

The latency is in the standard, so they would have to deviate from it. 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.

Why do you say the latency would be significantly higher? That’s manufacturer 
dependent since they aren’t locked to the full cellular PHY.

The 450 is going to smoke the Telrad from a latency standpoint. 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.

Is anyone looking at both these options? Pros and cons of one vs 
other? 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?
