New IEEE Standard - Active. Millions of IEEE Std 802.15.4g(TM)-2012 based devices are currently operating in Sub-1 GHz frequency bands to provide the low to moderate data rate capabilities. IEEE Std 802.11ah(TM)-2016 may operate in the same Sub-1 GHz frequency bands and provides higher data rate capabilities. This recommended practice enables IEEE Std 802.15.4g and IEEE Std 802.11ah to effectively operate in license exempt Sub-1 GHz frequency bands, by providing best practices and coexistence methods. (The PDF of this standard is available in the IEEE GET program at https://ieeexplore.ieee.org/browse/standards/get-program/page/series?id=68)
