IEEE 11af vs 11ah-difference between 802.11af and 802.11ah

This page on IEEE 802.11af vs 802.11ah describes difference between 802.11af and 802.11ah. It also provides link to 802.11af and 802.11ah basics.

Both 11af and 11ah falls under the IEEE 802.11 Wireless LAN family of standards. The increase in demand for M2M applications and to offload the data demand from cellular network have lead to development of these standards. Both of 802.11af and 802.11ah works on 1GHz frequency spectrum. They provide long range and low power operation.

Following two sections provide major difference between the two 802.11 standard versions and mention links for further study on these technologies. As mentioned 11af will have larger coverage distance compare to 11ah. Both the standard based products deliver data rate of about 600 Mbit/s.
