Wi-Fi HaLow
Long-Range IoT
IEEE 802.11ah, also known as Wi-Fi HaLow, is a wireless networking standard that operates in unlicensed frequency bands below 1 GHz.
A key advantage of using lower frequency radio waves, such as 915 MHz, is their ability to travel longer distances than higher frequencies like 2.4 GHz and 5 GHz, given the same transmit power. Therefore, Wi-Fi HaLow targets operations within the sub-1 GHz frequency spectrum.
Another crucial factor in achieving long-distance RF signal transmission is channel width. In any frequency range, narrower channels enable longer transmission distances compared to wider channels. Conversely, while wider channels can carry more data, they typically have a shorter range.
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.
