If you need the noise immunity, you probably need the sync as well. ;-)

It's doing a bit over 10Mbps/1MHz (AF5). Rumored 1024QAM. GPS sync, less than 24W. Better noise immunity than even AirPrism (although it is exceptionally good) in initial testing. Connectorized... So it's only niche is GPS sync? Really? For $399? With as low latency?

There are plenty of other products that can get you whatever BW you need (cheaper) with adaptive. If you are looking at AirFiber 5x, you are almost definitely doing that for the Sync of 2 or more links off a tower. That’s the niche of the product as far as I see it.

When you add sync, you can stack and overlap. If your going to venture into AirFiber, your already past the 'small potatoes' category IMO and you probably need to upgrade a good 2-3 links...

If you do rings and a link goes down, more traffic starts going the other direction, or reverses completely. So IMO, 50/50 is fine because it's not full duplex and I don't want to have to flip a link from 75/25 to 25/75 (or whatever options there are). A link goes down, traffic changes and I do not want to take down yet another link to fix perhaps a temporary issue. OR cause a much larger permanent issue, e.g. config apply or reboot makes the radio(s) not come back up. And AFAIK, the AF5X isn't capable of FDD. It's not your regular airFiber with two radios, or separate Tx and Rx antennas, or whatever it is. On 3/12/2015 4:17 PM, Josh Luthman wrote: <blockquote> We're ISPs. Our backhauls don't really need any upstream other than the upstream needed to sustain downstream. Could you first get an idea on what the benefit would be? If it would be <5% additional bandwidth it doesn't make much sense. Sync isn't a big deal to me unless I replace ALL backhauls with af5x which just isn't a realistic possibility.

It could be done if you didn't care about having multiple units synced together (as the framing would be changing). I don't know how much more in one direction we could make this and meet DFS rules for those bands... Is there a need for this?
