802.11ah - 900MHz

[sfx2000]

Good article...

"WiFi is preparing to ride the unlicensed 900 MHz band, reports EE Times. Chips for the upcoming IEEE 802.11ah standard are expected to hit the market starting in 2015. They will have to compete with numerous other protocols for home and building automation in the unlicensed 900 MHz band, including Zigbee and Z-wave. "

802.11 is turning out to be the baseline for much of the "internet of things"

the US 900MHz band is just a bit more than 20MHz in total. That's 1/3 the size of the 2.4 GHz band. And the band has lots of freq. hopping SCADA telemetry.
One must wonder... Is this to be a mobile device, low speed short range wireless??

This is mainly just to add a "Standard" for a "Non-standard" based band. In other words, currently, there are all kind of devices running in this band, using any standard for data transfer they wish. This new "standard" will still have to follow the bands limits (no constant use, low power, etc.) but will use standard methods (802.11ah) to transfer data.

This will NOT be for standard everyday "wifi" usage.

For the 902-928MHz band, a standard is sorely needed.
It should NOT be in the 802.11 family - due to user confusion.
It should/could be 802.x.x like Bluetooth is 802.15.3 and 802.15.4 is the MAC/PHY used by ZigBee, ISA 100.11, 6LowPAN and others.

To do any sort of data rate in 902-928, like 1Mbps (as has been done for years), the US FCC requires freq. hopping. That's something 802.11b/g/n don't do.
