These are Huawei radios?
I don’t know enough about the chipset. I do know what can be done with certain ones though.

But this chipsets all have limits. So this is a TDD Radio and stays a TDD Radio. It does 64QAM max and this will not change with firmware … So dont expect more than 50Mbit aggregated on a 10MHz Channel. And dont expect the features of full blown FDD LTE Basestations from Huawai et al. At the time this radio belongs to alvarion it promised 2x10MHz Channels for WiMAX. Is this implemented now (Should be no problem with SDR Radio ;-)) ? I dont have heard any benchmarked numbers from telrad which gives hope this radio will do much better than a wimax radio Von: Af [mailto:[email protected]] Im Auftrag von Rory Conaway via Af Gesendet: Mittwoch, 5.

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?
