Any news on 802.11ac Wave 2?


Does anyone knows if it's in roadmap for an AP?

I heard that there is a problem because you can't afford more than 1Gbps on copper ports and this is limitation for ap bandwidth 🙂

Unlikely to be a scenario in the enterprise where more than 1Gbps is needed on the switch port to an AP, so no worries there. 🙂

Yes please can we get some kind of roadmap for the Wave 2 equipment, and some specs/pictures.

I saw a picture or two of the new 4x4:4 Wave 2 units in a Extreme presentation but have not seen any info regarding them.
We cannot publish roadmap type of info in this forum. I would suggest you reach out to your local SE and ask for an update.

As for the bandwidth limitation there are also changes on the horizon on the wired side with things like 2.5G and 5G ethernet port speeds that will address that concern. We also have APs with dual ethernet ports as well.

In addition you're not actually going to need more than 1Gbps full-duplex wired ethernet in an enterprise environment. Wireless is half-duplex, and a 3x3:3 MIMO client at 80MHz has a max PHY rate of 1300Mbps (in a clean environment, within 30ft of the AP). Account for real-life overhead of 35% and you're under 1Gbps again.

Admittedly you could then exceed 1Gbps if the 2.4GHz radio is in heavy use, but personally I've been wishing for APs with a single 5GHz radio as I already turn off some of my 2.4GHz radios to avoid interference. As a bonus they would easily fit in 802.3af (I know the 3825 does, but even so it must be a squeeze).

Perhaps the following webinar will be usefull but it would seem that it is postponed for now

So, does anyone know whether we are talking about year 2015 or 2016 for "wave 2" products?

Extreme Networks will be announcing the Wave 2 APs before the end of the year; availability will depend in the country you are in and an estimate will be provided at the time of the public announcement. Having said that, could you expand a little bit as to why you require Wave 2 solution at this time. There is a lot of marketing hype and misinformation in the industry and we would like to keep it real 😉. When do you expect to start rolling out Wave 2 clients?

Thanks,

Great, thanks for the information.

I have different, well let´s call them "reasons":
  • Why "wave 2" ASICs and not "wave 1" chipsets? They are newer, also have more CPU power for handling more concurrent clients?...
  • We´ll have a new building (around 11/2015), so I´m looking for an appropriate solution. So I can wait for the new wave 2 access points.
  • Also, "wave 2" access points (39xx series?) will probably have longer support by extremenetworks.
  • When students come with their latest Y/X/T/I phone 6/7/8, we´ll have our first wave 2 clients and we will still have 802.11a/g activated for the rest of our people, I know what you want to say 😉

I can't really argue with you wanting to be on the latest and greatest when it is available. It really comes back to ROI or risk/reward economics. Comparing apples vs apples, a Wave 2 AP will support more 11ac clients, but new features (like MU-MIMO) will limit the number of users that you can support in MU-MIMO groups, which doesn't exist with Wave 1. Keep in mind that the MU-MIMO works one-way, at least in the first iteration, for communication from the AP-to-the-client so your traffic profile will have an effect on how much you will gain from MU-MIMO when the student's devices get there. Also because the first gen of Wave 2 is 4x4:4 the cell sizes are likely smaller vs. 3x3:3 although you can support more density - the reason for the smaller cell sizes is that the total amount of power you can put out is going to be the same whether you are using a 2x2, 3x3, or 4x4 so your density is higher but your coverage is smaller. From a cabling perspective you may want to consider dropping two E/N in the new building, for resiliency in Wave 1 / 2 and for more wired bandwidth, you may push the envelope for Wave 2, but more likely for whatever comes next (802.11ax, etc.) and you want to be using Cat 5e or Cat6 to set you up long-term for 2.5G E/N. You may want to consider Cat6 for 2.5G/5G E/N if you are thinking that far out. The 4x transmitters also means more power so make sure you are going with 802.3at on all your E/N ports. As far as longevity there is plenty of runway on the Wave 1 since we support for 5 years after end-of-sale and we are not anywhere close to EOS of Wave 1. My point here is not to dissuade you one way or another but to give you some information for your planning so that you can decide which is the best for design for your deployment. Hope this helps!

Cheers,

Well, we ́re a public university. We received a budget for each piece of hardware, i.e. in my case budget for the given switch ports and access points

The building (purely made out of cement/steel) itself is rented. Looking at the construction plan, there ́s 1 RJ45 port in each smaller seminar room (somewhere at 3m height in one corner) besides some other ports on the ground of the room. Some into the corridors. In bigger lecture halls there are 2 (for up to 300seats), also somewhere placed into the room. The access points will be placed right beside it. Well, it has to look "nice"... No antenna design at all. Only some radio tweaking.

So, I will probably buy "AP3925" access points and hope for the best...

I don ́t know anything about the new extremenetworks access points, but this year some vendors of home wifi access points released devices with 1x 2.4Ghz and 2x 5.0Ghz radios/ASICs. This would be very helpful in our case, too.

Hi Willian,
Which are the Extreme Network AP models Wave 2?
Are the Wave 2 AP Extreme Networks compatibility with Client Wave 1? How much compatibility ... (100%, 90%)?
Which manufacture o brand Client Wave 2 are compatibility with the Wave 2 AP Extreme Networks function or you tested with it?
Thanks,
Erick Lobo

Hi Ronald, do you find the Wave 2 -Client (not wave one -client ) ?
Thanks,
Erick Lobo
