Abstract

IEEE 802.11ah enables new use cases such as smart grid and smart metering for 802.11 with an increased transmission range that reaches up to 1 km at 150 kbps. However, such a large outdoor network creates more hidden nodes due to a much higher path loss between stations than between a station to an access point (AP). 802.11ah has adopted a slotted medium access scheme and an AP assisted medium access scheme to mitigate the hidden node problem to enable energy efficient medium access for a large outdoor network. This paper presents details of the protocols being developed in the standard and evaluates the gains of the protocols.
