Wi-Fi HaLow is a low-power, long-range variant of Wi-Fi, primarily based on the IEEE 802.11ah customary. It operates within the sub-GHz vary (850-950 MHz), enabling it to penetrate obstacles similar to partitions and buildings and join a bigger variety of IoT units over a lot higher distances.
In February, Morse Micro showcased Wi-Fi HaLow’s capabilities by attaining a 3-kilometer (1.8 miles) video name, setting a document for long-range connectivity utilizing the 802.11ah customary. In its newest vary check, Morse Micro carried out trials at Joshua Tree Nationwide Park, a rural space identified for its expansive open areas and minimal RF interference. This check efficiently achieved a powerful vary of 16 kilometers (10 miles), 5 occasions the earlier distance.
For the experiment, Morse Micro used its MM6108-EKH01 analysis package, which includes a Raspberry Pi 4 and an MM6108-MF08651 Wi-Fi HaLow reference module. The package outputs 21 dBm of energy via a 1 dBi antenna, leading to 22 dBm of whole radiated energy. The purpose was to evaluate Wi-Fi HaLow’s real-world efficiency with customary gear.
15.9 kilometers
Morse Micro calculated the theoretical most vary of the system primarily based on the IEEE 802.11ah customary, contemplating components like sign energy, antenna acquire, and free-space path loss. The estimated vary was 15.9 kilometers. Throughout area exams at Joshua Tree, the group achieved a 2 Mbps UDP throughput on the most vary, demonstrating that Wi-Fi HaLow can preserve long-distance connectivity whereas delivering significant knowledge charges.
HaLow isn’t nearly distance, nonetheless. The know-how’s power-saving capabilities can prolong battery life considerably. This might be a game-changer, particularly for units working on coin batteries, permitting them to operate for months with no battery change.
Writing concerning the newest milestone, Morse Micro’s group stated, “Our testing in Joshua Tree Nationwide Park demonstrates that Morse Micro’s Wi-Fi HaLow isn’t nearly spectacular numbers – it’s about delivering actual worth in environments the place you want it most. This check proves that we are able to attain the utmost theoretical Wi-Fi HaLow vary whereas nonetheless offering vital and usable throughput. Whether or not you’re working in distant, rural areas or deploying IoT options throughout huge landscapes, Wi-Fi HaLow can carry out persistently and reliably.”
