Wi-Fi HaLow

IEEE 802.11ah is a wireless networking standard that uses the Sub 1 GHz unlicensed frequency bands. The laws of electromagnetics and communication theory dictate the relative trade-offs between power, distance, and radio frequency (RF) signal reliability. For any given transmit amplification power, radio waves transmitted in the 2.4 GHz and 5 GHz bands do not travel as far as radio waves in lower frequencies, such as 915 megahertz (MHz). For this reason, Wi-Fi HaLow focuses on operation in the frequencies referred to as the sub-1 GHz spectrum.

Wi-Fi HaLow offers a balanced mix of Range and Data Bandwidth, making it ideal for Industrial IOT Applications. Focussed on Industrial IOT, Vizmonet’ s Wi-Fi HaLow portfolio is committed to unleash several applications to drive Industry 4.0 forward.
