Notable, is that the propagation characteristics seem to mean that that this is a single-room only solution.

Nice it's here. Yep. The higher the wireless frequency the stronger the SNR required which makes you wonder if it's that close, why not just run a wire?

Damn...I feel like I just updated to AC, but that was in Nov. 2014. I have no need for faster speeds/more coverage at the moment. Big fan of TP-Link, got the well reviewed Archer C7 for $40.

Seems the 60GHz can only cover an area around 10' x10'

These thingies are based more on Psychology of Consumers.

The most expensive part in the device is probably y the design of the Impressive Plastic Box that seems to be more inspired by "Sex symbols". rather than technology.

QFT.

SNR is probably highly augmented by the proximity of the 8 "Sticks" emitting one into the other.

Quote: "Discussion about the Proximity Effect of Multiple Antennas. From the above chart, we can see antenna efficiency drops from 100% to 19% when the total antenna count increases from 1 antenna to 4 antennas and results in an additional 7 dB of gain loss. A 6 dB gain loss means the operating distance is shortened by half and a 7 dB loss means that the operating distance is shortened from 100 meters to 45 meters due to the additional installation of antennas. Hence, the proximity effect of multi-antenna installations greatly affects the receiving efficiency and should not be neglected".

------------------
The actual power output (in mW) is Not allowed to increase for many years.

Playing with inside working of Newer WIFI Chipset is based on trying to improve functional output through "Tricks" like MIMO, allowing vendors to claim "Big" improvement of the inner specs without getting sued.

Designing the correct Antenna system for such inner circuit will be very expensive ans will look very cumbersome in the home enviroment.

As a result many of the Improved WIFI is based on the Sneakers marketing schemes rather tan improving functional technology.

To be fair, that avlex paper, does it address beam-steering? I think with beam-steering you get different results than what the paper concluded?

Yeah the MIMO system is suppose to compensate a little.

On the other hand, giving that frequency of the WIFI is higher (i.e., much small wave length) and that the frequencies are very close, the way the Entry Level Wireless Router deal with Antenna is a big lose.

There is a Good reason to Intel providing this Antenna for its Dual AC PCIe card rather than putting on the typical dual or triple sticks that almost all others WIFI provides.

This is only good for single room wifi and if i'm staying in the same room I might aswell go with a wired connection.

TP-Link Blocks 3rd party firmware so they are off my list for a brand i would purchase.

lol so basically none of this interest me.

I'll wait for Li-Fi.

What's the "reason?" Just for being able to relocate the antenna?

My Zotac mini-ITX board came with a black antenna that kinda looks like that and doesn't say "Intel." The cords are thinner and kinda stiff. The WiFi module is wireless AC with Broadcom 802.11ac chip. Neither the I/O shield antenna connectors nor the antenna's connectors have any indicators of which connections are 5GHz or 2.4GHz. Maybe there are markings on the actual module that leads to the I/O shield, but I haven't been able to check that.

As far as I can tell, it's not a particularly good performing antenna. Also, with the stiff cords coming out at a 45-degree angle, there's not a practical way to mount it.

People keep saying that about custom firmware. The FCC restrictions apply to all router manufacturers, right?

Is does apply to all manufacturers.

How they implement it is the difference.

Example Asus just made that part of the firmware inaccessible to end users while still keeping their firmware's open source. Equals Simple and logical fix.

Example TP-Link decided to block all 3rd party firmware. Equals Lazy

Asus understands the importance of 3rd party firmware and their communities.

Merlin makes great 3rd party firmware for asus routers so good they have taken ideas out of his firmwares and including them into their own.

I seem to recall, didn't Asus end up hiring good ol' Merlin? Probably the smartest move they have/could make
