802.11ah: WiFi Standard for 900MHz
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. The 802.11 […]
The 802.11 standard is the most broadly used form of wireless local-area networking. IEEE has already developed a 1 Gbps standard for 5 GHz (IEEE 802.11ac) and a 7 Gbps standard for the 60 GHz band (802.11ad). Those compete against other protocols for home video connectivity.
While 2.4 GHz WiFi commonly uses a total of three 20 MHz channels (in the available 85 MHz of spectrum), the 802.11ah standard uses a more restricted 902-928 MHz band (in the United States). ...
