Anyone already hands-on with this latest device? Particularly interested in their new active antenna design and the impact on sensitivity, as this is something new.

Quite a few interesting design decisions in that product, curious to see what impact it will actually have (beside the increased price. Ouch.)
 
It doesnt matter wath you have in the Router as long you NOT also bring out USB/clients/devices that support this futures and NOT a word about that in the comercials, just a small notis in small printing on there webb.

huh?
 
My personal guess with the active antennas is it will improve reception (as the weak signal received from the client will be immediately amplified before being sent down to the router, reducing the path loss of the weaker received signal), but will have next to no impact on transmitting (unless they had some major cross-talk issues previously, which I doubt).

Sounds greate lets see if it works in real life, BUT still isnt the 802.11ac highest speed 1300Mbps as standard correct me if am wrong? And let me know when we can have wireless adapters that can use those aggregate speeds and perfomence. http://drivers.softpedia.com/get/Ro...EAR/Netgear-R8500-Router-Firmware-10042.shtml

You can get four streams now, for up to 1750. If you add Broadcom's proprietary NitroQAM (like used by this router), then that gets to 2150 Mbps.

2150 (5G1) + 2150 (5G2) + 1000 (4G) = 5300.

Let's revise that math to clients that are generally available, and taking away proprietary extensions, but still considering the Maximum Marketing Number

AC1300 (3*3:3) + N450 (3*3:3) = AC1750 class

Or take it to a more practical/common level with most clients in the field..

AC867 (2*2:2) + N144 (2*2:2, narrow channels) = AC1011 class..
 
So yes, I do take exception to Broadcom's X-Stream and Turbo/NitroQAM propaganda, as it generally doesn't translate into real-world results.

Confirmation bias not withstanding - I could do a real-world blind test, and I do believe that nobody could really tell the difference beyond AC1900 class...

Just because you don't have a client that can handle 4 streams does not mean the router cannot. Take a pair of routers with 4 streams support each and bridge them - you will get the advertised link rate.

We're talking the class of the router here, not the class of your home network.
 
Just saying - buying a big AC5300 class router likely will not have much benefit compared to an AC1900 class device - and the AC1900's are getting to a very good price point for most users...

;)
 
And probably more to the point - the whole AC**** class rating system is getting to the point that it sets very unrealistic expectations of customers/end-users...

I tried to raise this point a year/year and a half back, and it fell on deaf ears...

We're talking the class of the router here, not the class of your home network.

My home network really isn't relevant here - except that I can pretty much take advantage of an AC1750/AC1900 class AP - what my point is that in general, many might not be able to... e.g. the AC1011 indication - see what's on the store shelves client-wise...

Show me an 802.11ac client adapter that can do four-streams...
 
And I'm not trying to be mean-spirited or malicious...

Just pragmatic and practical - when we start seeing Wireless AP's in the consumer space at 300-350, much less 250 (dollars) when a 130 dollar router does the same job, someone has to raise this point...

We're seeing a spec-war, but this is one that no-one really wins.. and it will lead to a trail of unhappy customers at the end of the day. And those specs are really going in the wrong direction...

I'd like to see better WAN-LAN support, more stable/secure firmware, ease of use, better wireless performance in dense environments - less bugs in features already deployed, and better security overall - RMerlin - you're contributions here have been key for a whole community...
 
Yes you have right. Like they promise/says in advertising, you will receive from your network this and this and most of ppl belive that and buy it and sitts then at home and wonder, oh well why dot I NOT get that speed now?
