The author kinda bungles his analogy/explanation of collision avoidance and detection. Wireless networks don't use CSMA/CD. They use CSMA/CA. There's a huge difference, and it's one big reason why wireless throughput won't ever come close to PHY speed. Wired ethernet uses CSMA/CD and it's one of the reasons it won the LAN networking wars of the 80's and 90's.
I build public Wi-Fi networks, you've probably used one of them. AMA if you have Wi-Fi questions. To say it "sucks" is a bit harsh. It's delivering multiple hundreds of Mbps to you via an unlicensed contention-based medium. The air interface is like sending packets over a noisy Ethernet hub; it's impressive it works as well as it does. That said, this article's a good primer on some of the protocol's fundamental chal…
Is there a good suite of tools to actually measure the quality of a wifi connection and/or surface, even help diagnose, problems?
adjusts Meraki APs to auto power, 40mhz channel width on 5ghz I was dismayed at how terrible range was in my new, Silicon Valley-sized house (~1100sqft). Even with a Meraki AP at the front wall, it would work line of sight about 30 feet and start having issues as soon as I stepped behind a wall. Having a couple APs has mostly solved my issues, but even so, it feels like overkill for such a tiny house. But the neighbo…
This article should be read by everyone working in open space offices across the world expecting to get decent speed and reliability out of Wi-Fi with more than a dozen people in a single room. An open space office (or any office) for a company that depends on the Internet for any of its work without Gigabit Ethernet cables sticking out of every workstation is pretty damn foolish.

Why? TVs aren't very portable, carrying content over a wire makes much more sense.
I have a partner who hates wires. Wifi is a very normal thing for TV's, Games consoles, Chromecasts... etc;

Any idea why we do not have public, encrypted wifi? Seems like it should be easy / trivial to fix, and protects people from passive listeners.

I splurged on one of the expensive tri-band routers and honestly now the wireless is good enough that I don't care.
I used to live about 1/4 mile away from any other houses, and I never got why people always complained about wifi. In my experience it always worked well, was fairly fullproof, and had fast enough speeds that it was never an issue. 2 years ago I moved into a condo that has 25 wifi APs within range of me right now. Now I get it. Getting one of the high-end tri-band routers as you said did help, but it's still a diffic…
