In this web content, the author discusses the 802.11ah WiFi (HaLow) standard, which falls between standard WiFi and long-range, low-bitrate options. The author highlights some products and chipsets that integrate this standard, including an Ethernet range extender kit and an 802.11ah-based WiFi extender. The author conducted distance tests and found that a strong signal could be maintained up to 300 meters, with some attenuation when obstacles like trees were present. The author also mentions that 802.11ah is compatible with standard Ethernet and WiFi protocols and uses the 900 MHz spectrum, which allows for potential range extension.
