Summary:

802.11ah: Better range, lower bandwidth

802.11ad: Better bandwidth. Doesn't go through walls.

802.11ax: Successor to 11ac expected in 2019

View on HN

There is 802.11ay expected in 2019 as well, a step up from 802.11ad using the same 60Ghz. Up to 20Gbps, 3x the rate of 802.11ad.

I really really want 802.11 ay and ax to come faster, it will truely bring us to the world of Wireless with the speed we expect from 1Gbps. Wireless Display to TV no longer be slow of choppy with quality degradation.

60GHz basically means "same room only". Won't go through walls for sure. Should be useful for open space offices though.

This can be an advantage depending on the use-case. E.g. an access point in each home or room means the signals aren't interfering with each other.

Someone is going to make a killing on tiny, inexpensive RJ45 60GHz access points and switches that support PoE. Killer use case: stick it into a wall, and everything in the room gets gigabit speeds. No wall warts to deal with.

Ubiquiti already have something like this, although only 2.4Ghz b/g/n - https://www.ubnt.com/unifi/unifi-ap-wall/

About AUD$100/unit.

Ruckus Wireless has a 2.4Ghz and 5Ghz a/b/g/n/ac - http://www.ruckuswireless.com/products/access-points/zonefle...

Going to be much more expensive than the Ubnt unit.

5ghz AC doesn't go through my plaster walls now. I've got two walls between me and my Airport Extreme and about 10 physical feet and have half signal showing on my phone.

In this case, what they mean is that the signal will be truly line of light. As you go up in frequency, radio starts to behave more like light so while you may get some convenient reflections here and there, for the vast majority of the time, if the antenna doesn't have a clear path to the transceiver, you won't know there even is an access point.

I suspect this can be quite convenient for various places where you want to limit access to individual rooms etc, but don't want to deal with the tangle of cables and ports that a wired network would require.

If you want a good 5ghz AC setup buy a couple of good repeaters with seamless handoff and put one in each room that's what 5ghz was mainly designed for.

Airport is a very crappy 5ghz ap to begin with so is the Google elcheapo-de-slink.

Not really.

As I always request in these threads, I'd like someone to point me to a peer-reviewed paper that shows 5GHz being attenuated more by building materials than 2.4GHz.

The usual culprit is that people put their 5GHz networks on the old "low power channels", which nearly every router I've ever seen chooses by default. Half the power, half the signal in the next room, of course.

Choose channel 149 which is full-power.
