Because of the usage of sub 1GHz (S1G) transmission bands and narrower channels, Wi-Fi HaLow increases the coverage of an access point (AP) up to 1 mile in distance and can handle up to 8000 client stations (STAs). Operating in a lower part of the spectrum, Wi-Fi HaLow can penetrate walls and other physical barriers better than the 2.4/5GHz Wi-Fi bands.
HaLow's new sophisticated channel access mechanism called Restricted Access Window (RAW) reduces energy consumption — an important performance indicator for 802.11ah — since the stations can sleep almost always except for the allocated time intervals. HA92 Class requires a fraction of the power of a conventional Wi-Fi module. Low peak power requirements enable the use of small batteries which can last many years.
