Qualcomm's New 802.11ax Chips Will Ramp Up Your Wi-Fi (cnet.com) 53
Your home Wi-Fi performance could soon get much better thanks to new Wi-Fi chips that Qualcomm announced today, the IPQ8074 system-on-chip (SoC) for broadcasters (routers and access points) and the QCA6290 SoC for receivers (Wi-Fi devices). They belong to the first end-to-end commercial Wi-Fi portfolio to support the all-new 802.11ax standard. From a report on CNET: Qualcomm says the IPQ8074 is a highly-integrated all-in-one platform designed for access points, gateways and routers. The 14nm chip integrates an 11ax radio, MAC and baseband, and a quad-core 64-bit A53 CPU as well as a dual-core network accelerator. It uses a 12x12 Wi-Fi configuration (8x8 on the 5GHz band and 4x4 on the 2.4GHz band) and supports MU-MIMO for uplink. As a result, it can deliver up to 4.8 Gbps while maintaining fast connections over a larger coverage area than any 802.11ac chip. On the client side, Qualcomm says the QCA6290 SoC can offer up to a 4x increase in throughput speed in a crowded network. It supports 2x2 MU-MIMO and can realize the full benefits of the 8x8 MU-MIMO thanks to its 8x8 sounding mechanism. The chip can combine 2.4GHz and 5GHz bands using its Dual Band Simultaneous (DBS) feature to deliver up to 1.8 Gbps Wi-Fi speed. Compared with 802.11ac, the chip can reduce power consumption by two-thirds.

Finally some good MIMO tech coming to replace AC. I was a bit disappointed when I purchased my first AC router thinking the dual band would be for simultaneous connections. Boy was I wrong. Advertising lingo confused me into thinking it was something it wasn't. Sounds like AX MIMO is what I thought AC was going to be. Reduction in TDP is a welcome upgrade too as most routers do not have active cooling and some models were burning out from the load. I would prefer a router that all things being equal,

I think that you'd find yourself in the minority, especially when the fans get dirty and start making noise. It'll be even worse for those who ceiling-mount their WAPs since it'll likely be unobstructed by anything that would block the noise.

Now only if that AP that has capability of 4.something Gbps would be connected by more than a single 1Gbps ethernet line.
10GbE is still prohibitively expensive for most build-outs of wireless networks.

It doesn't do you any good to put up dozens of APs and to provide literally hundreds of switchports if you're only uplinking at 1000BaseT. Even 10GBaseT would be a limit in such an environment.

Now taking bets on if gigabit Ethernet will still outperform wireless in almost all use cases that don't require someone to be able to sit in their office chair with their laptop and spin continuously like this sentence...
In a home environment wireless can out perform wired as long as you don't have interference issues with your neighbors, but in an office environment where everyone connects to the same or a limited number of WAPs you have contention issues that bring the available bandwidth for each client down to less than optimal.
For a while I worked in an "open plan" office where everyone connected via wireless, many people used a tethered cell phone for access as it was SO much faster and more reliable than using the of

If your ISP is BT, you can probably get away with 811b. 100 Base T is definitely overkill.

With the average broadband speed who needs this much headroom in Wifi? Maybe some plus to having less power consumption, and built in compatibility long term. But most won't ever be able to experience any difference over AC speeds or even some N speeds. This obsession that most people need or 1 Gbps wifi is not being honest with consumers. As if a continually increase in local network speed somehow results in better internet speed. I know plenty of consumers who bought a $200 router and complained it never

Yes, this is true. 4K streaming content will become common place at some point then followed by 8K. This will probably happen because at some point you won't be able to buy a 1080p television and then eventually not even a 4K one but you didn't even mention some of the real challenges around WIFI that until recently we haven't even a made a dent in.
Coverage area is a real problem for WIFI especially when you consider a 2000-3000 sq. ft. house let alone a 4000-5000 sq. ft. house. The conventional solution

~97% of Android devices STILL have fucked-up wpa-supplicants that won't switch APs unless the AP literally kicks them off.
Yup this is a big problem. By "kicks you off" you mean lose the signal of the current AP (MAC Address) entirely forcing it to search for another AP. It's both a client and a server problem which is remarkable considering that we've been going at wireless networking for almost 20 years now. How hard is it to periodically measure the dB level of the signals and seamlessly switch to the one with the better signal?

Fair enough but how many of those home owners actually possess the ability to set it up? Hire a business contractor to do that for them? Most people that I know that own that type of home aren't rich by any stretch of the imagination.

At some point, it probably WILL become cheaper & easier to transmit insanely fast data without wires. At least, if you have fiber to each room, feeding a 60GHz access point with 20 feet of cat6 doing 10-gig ethernet. At that point, the wireless network is basically short-ra

Probably never for USB sticks or built into phones etc. To get the full bandwidth you need 12 antennas it appears. Like 802.11AC, most devices will only be able to use a small fraction of the available bandwidth.
That's probably for the best, we don't really want one laptop trying to transmit over the entire 2.4 and 5GHz spectrums at once. 2.4GHz is bad enough already, with existing wifi and Bluetooth. At least 5GHz has poor penetration.

Wattage on the radio, and antenna inputs.
You don't need the capability to plug 8 antennae into your phone, but you may want that for an access point. Also, your phone would drain the battery if running with the wattage that a normal AP does, from either PoE or a wall wart.
