There used to be a good wikipedia article about LoraWan, which is better than this (for IoT) in just about every way, but it has been replaced with this: https://en.wikipedia.org/wiki/LoRaWAN LoraWan consumes power at a similar rate that BLE does, except it has a 20km range. You're talking about months (or even years, depending on your interval) of usefulness out of a CR2032 coincell battery. Sidenote: the removal of…

Do you mean by wikipedia's definition of stolen? Because some things, like for instance: the description of Lora taken from the website that exists to provide descriptions of Lora to people, has an implicit usability.

Like I said, this irked me more than it probably should. I totally get sometimes stuff will get caught in the margins.

So, can my Macbook connect to a HaLow router, or is this a new protocol that will require all new hardware across the board?

Given that it runs at 900 MHz, it will require new hardware. At a minimum, it will require an antenna tuned for the new band, in addition to whatever changes to the WiFi baseband processor are needed to go along with it.

Not exclusively, by the sound of it - the press release notes "Many devices that support Wi-Fi HaLow are expected to operate in 2.4 and 5 GHz as well as 900 MHz".

It looks like this runs in the 900MHz ISM (US) band, so we'll all need new hardware. The longer range is nice. Interference from other 900MHz transmitters (cordless house phones, baby monitors, etc.) may not be. It seems everything old[1] is new again. 1. https://en.m.wikipedia.org/wiki/WaveLAN

I'd hope no one's phone is running in 900MHz - what does DECT use in North America?

1.9 GHz

Wikipedia's mission is NOT about usability, but to provide an encyclopedia that can be used, edited, forked, reproduced EVERYWHERE without anyone having to fear lawyer attacks.

It's not a "free as in free beer" encyclopedia, it's a "free as in truly free" encyclopedia.

(Yes I know that this is only valid for the text content, images (e.g. logos) and screenshots are not free but used under different legal regimes in different countries)

So signal drops every time you use the microwave... No thanks.

I thought microwaves (oven) mostly interfere with the 2.4 GHz band. That's why games of Starcraft always lag out when one of the players starts cooking a hot pocket. That's why it's preferable to use 5 GHz 802.11n or 802.11ac, unless you have walls that block the higher frequencies.

that's not how copyright law works. you may argue that it should work that way, but it does not work that way unless you petition Congress to modify it
