Most devices now feature Wi-Fi modules capable of handling 802.11 b/g/n at 2.4 Ghz (and 5 GHz for dual band Wi-Fi), and newer devices and routers boast 802.11ac connectivity @ 5GHz with increased bandwidth (up to 1.2 Gbit/s in theory, maybe around 400 Mbit/s in practive), and in some case increased range with beam-forming. But thanks to an article on EETimes, I’ve learned there’s another upcoming Wi-Fi standard called 802.11ah operating in the 900MHz range, with data rates from 150 Kbit/s with a 1 MHz band to as much as 40 Mbit/s over an 8 MHz band, lower power consumption, and a least double of the range of a typical 802.11n device,capable of covering an area of about 1 km2. The target applications are sensors networks, backhaul networks for sensor and meter, and extended range Wi-Fi, as the standard allows long range and more clients at low bitrates. This new […]
