[quote]Smart Home devices, or devices belonging to the Internet of Things as it's known colloquially, haven't been as game-changing as many of us hoped they'd be.
Sure, you've got plenty of smart bulbs to choose from, and giants like Samsung are beginning to incorporate smart home devices into their smart TV platforms.
Unfortunately, engineering devices that are not only small enough to interface with a deadbolt or a light bulb, but powerful enough to transmit information via Wi-Fi, is tough to accomplish cheaply. Wi-Fi connectivity and the Internet of Things just haven't gotten along very well, historically speaking.
Which is why the Wi-Fi Alliance's HaLow announcement is such a big deal for the future of the smart home.[/quote]
Announcement: [url]http://www.wi-fi.org/discover-wi-fi/wi-fi-halow[/url]
[quote]With industry momentum mounting around a low power Wi-Fi® solution, Wi-Fi Alliance® has introduced Wi-Fi HaLow™ as the designation for products incorporating IEEE 802.11ah technology. Wi-Fi HaLow operates in frequency bands below one gigahertz, offering longer range, lower power connectivity to Wi-Fi CERTIFIED™ products. Wi-Fi HaLow will enable a variety of new power-efficient use cases in the Smart Home, connected car, and digital healthcare, as well as industrial, retail, agriculture, and Smart City environments.
Wi-Fi HaLow extends Wi-Fi into the 900 MHz band, enabling the low power connectivity necessary for applications including sensor and wearables. Wi-Fi HaLow’s range is nearly twice that of today’s Wi-Fi, and will not only be capable of transmitting signals further, but also providing a more robust connection in challenging environments where the ability to more easily penetrate walls or other barriers is an important consideration. Wi-Fi HaLow will broadly adopt Wi-Fi protocols and deliver many of the benefits that consumers have come to expect from Wi-Fi today, including multi-vendor interoperability, strong government-grade security, and easy setup.[/quote]
Pretty cool.
900MHz is awfully close to some GSM spectrum, no?

[URL="https://en.wikipedia.org/wiki/GSM_frequency_bands#GSM-900.2C_GSM-1800_and_EGSM.2FEGSM-900"]Yup![/URL]
[quote]GSM-900 uses 890 – 915 MHz to send information from the mobile station to the base station (uplink) and 935 – 960 MHz for the other direction (downlink), providing 124 RF channels (channel numbers 1 to 124) spaced at 200 kHz. Duplex spacing of 45 MHz is used. Guard bands 100 kHz wide are placed at either end of the range of frequencies.[/quote]
Anyone know what the higher end speed limits will be?

It will not be too much of a hassle for Australians, given that our largest telco Telstra is cutting off GSM services at the end of 2016.

Too bad that most of the planet and a good majority of the USA's carriers run on GSM. The only worthwhile one that isn't GSM is Verizon on CDMA.
[QUOTE=sgman91;49489210]Anyone know what the higher end speed limits will be?[/QUOTE]
Probably pretty low, but most of these devices don't need more than a few kB/s to operate.

I was going to say I didn't think people still used GSM.
Interesting, will raspberry pi and other microprocessors adopt this? Is it feasable to be compatible with this and previous wifi standards?

The microprocessors don't give a fuck unless they have a wi-fi modem integrated directly into their silicon.

So for example on the raspberry pi zero which comes with wifi connectivity, it doesnt matter which standard of wifi the router is outputting, the pi will still be able to process it?

yep. doesn't matter to the pi how it gets it just that it gets it

That doesn't have built-in wi-fi [B]AT ALL[/B], you'd have to bang on a usb-to-wifi adapter or hook up a SDIO to wifi adapter to some of the GPIO pins.
Seriously, point it out to me where in the documentation/spec-sheet there is mentioned it has onboard wi-fi.
Not to be rude, but you've clearly not read those at all.
Yeah this is completely different than just your N card accepting signal from your AC router, this is operating on a different band. You WILL need a new card/radio for it to work.

But this is probably going to make my CWNA even more of a pain in the ass.

I must have been mistaken, but I am very interested in microprocessors.
low power wifi has a lot of potential
As an EE, as cool as IoT is, alot of it feels very frivolous (Especially alot of home IoT devices) with very few of the devices I've seen having real application.
Logistics have a real application with IoT, i.e. tagging each shipping container/whatever with a WiFi/Bluetooth enabled tag to get inventory status/tracking info/etc.
Fortunately the IoT standard is strictly low power to keep bandwidth usage low. Try living in a dense apartment complex and use your WiFi router at decent speeds, at that point fuck it and use Ethernet.
You know what I want? An IoT shower. Precise temperature, pressure, jet, music, and lighting control from my phone. That would be fantastic.

digital temperature for showers would be amazing period

99% could already be accomplished by bluetooth low energy. Welp, time to pitch that to my final project team.

And then some hacker changes the temperature from degrees Fahrenheit to degrees Celsius and suddenly you're in scalding hot water :v:

Optus, Vodafone and Telstra (and all State and Territory rail services) use the 900Mhz band for other services. And once Telstra shut down the GSM network, they're not going to let that valuable frequency go to waste. That said, the wireless, if permitted in Australia, will not be interfering with their frequencies.

IoT coffee machine, makes coffee while you laze in bed using your phone in the morning.
[QUOTE=Headhumpy;49491448]IoT coffee machine, makes coffee while you laze in bed using your phone in the morning.[/QUOTE]
So why add a "alarm clock" built into the coffee machine that automatically turns it on at a pre-defined time, so you only have to prep it before going to bed?
Call me cynical, but many of the IoT things are often just complex solutions to simple problems.
[QUOTE=Headhumpy;49491448]IoT coffee machine, makes coffee while you laze in bed using your phone in the morning.[/QUOTE]
I don't know. With IoT I always get the sense that the problem solved could have been done much quicker if I had gotten up. With coffee there is always the cleaning up, making sure you have coffee and water in the machine, making sure you have enough at home, getting up and grabbing it myself. In the end I could just make the coffee myself the time potentially saved from using my phone to start the process seems minimal and not worth the hassle.

I have an IoT hot tub, with lighting/jet/heat control
It's pretty baller
I can come home after a long day of work and it's already ready to go

Waking up smelling coffee in the next room would be absolutely glorious though

Hahaha, come to Europe, especially Eastern Europe and Russia.

Might actually be useful one day after all
I like the ah at the end because it'll be transmitting a lot of AH AH AH AH AH
do you get it its a porn joke
