This is fixed point to fixed point wireless. Suitable to replace the last-mile 
ISP, but not something that will talk to your laptop.

If they're using phase encoding or similar, that's pushing the ragged
edge I think.  Won't take much dip in the S/N before that comes back
to bite you on the tookus,

well... I loved that they aimed for low latency in their design.

The stuff is a bit pricy but what is backhaul today may be baseband tomorrow.

that's true, but they do that by being full duplex, broadcasting continuously.

> The stuff is a bit pricy but what is backhaul today may be baseband tomorrow.

it's not just the price, it's that it's a highly directional point-to-point 
setup, not something that allows more than two devices to talk at once.

Other big players seem to aim for low latancy as well, although in
different wireless network technology and in reality yet far away from
readily available products compared to the airFiber.

Just yesterday a finnish magazine Elektroniikka Lehti published an
article (in finnish), where Research Director of Nokia Networks is cited
to say:

"Nokia's vision 5G network means a system that brings users the best
10-gigabit data rates of one millisecond delay, but on the one hand, for
example, should IoT machine to run on battery power for 10 years. These
requirements for the data rate is the easiest to achieve, after all,
Nokia [has] already [demoed] LTE-Advanced technology 4.1 gigabit link.

One millisecond of latency is a very tough technical challenge."

Translation by Google, mods marked [] by me, link to the original article

<http://etn.fi/index.php?option=com_content&view=article&id=2222:zte-testaa-jo-5g-tukiasemaa&catid=13&Itemid=101>

Google Traslator does pretty good translation except on a sentence in
the beginning:

"ZTE, the test was examined in particular the so-called. Massive MIMO
Solutions, where the base station antenna 128 is used for the head."

should be

"In the test ZTE examined in particular the so-called Massive MIMO
Solutions, where the base station has 128 antenna heads."

Best,

Well, if they published their actual queuing delays, it would generally be
a different picture.

think.  Won't take much dip in the S/N before that comes back to bite you on the 
tookus,

They support many encoding schemes, and will use all channels in each direction. 
As conditions degrade, the speed will slow.

The top speed is using 1024-QAM modulation, it will then fall back to 256-QAM 
(which is the top that 802.11ac will use), and then to 64-QAM (which is the top 
of 802.11n)

This has far more in common with old fashioned microwave links than Wi-Fi
