Morse Micro has set a new benchmark for long-range connectivity. Their innovative Wi-Fi HaLow, a low-power variant of Wi-Fi, recently achieved a remarkable range of 10 miles (16 kilometers) during real-world testing.
This achievement not only surpasses previous records but also signals a significant step forward for Internet of Things (IoT) applications, particularly in remote and rural areas.
What is Wi-Fi HaLow?
Wi-Fi HaLow is based on the IEEE 802.11ah standard, specifically designed to operate in the sub-GHz frequency range of 850 to 950 MHz.
This unique frequency allows HaLow to penetrate obstacles like walls and buildings, enabling it to connect a larger number of IoT devices over extended distances.
Unlike traditional Wi-Fi, which can struggle with range and penetration, HaLow is tailored for environments that require long-distance connectivity without sacrificing data transfer quality.
Breaking Previous Records
Earlier this year, in February, Morse Micro showcased Wi-Fi HaLow’s capabilities by successfully conducting a 3-kilometer (1.8 miles) video call, which was an impressive demonstration of long-range connectivity.
However, during recent trials conducted at Joshua Tree National Park in the USA, the team achieved an astonishing 10-mile range.
This new milestone is five times the previous distance record, showcasing HaLow’s potential in expansive, rural landscapes with minimal radio frequency (RF) interference.
The Testing Process
For the recent tests, Morse Micro employed their MM6108-EKH01 evaluation kit, which integrates a Raspberry Pi 4 with an MM6108-MF08651 Wi-Fi HaLow reference module.
This setup allowed them to output 21 dBm of power through a 1 dBi antenna, resulting in a total radiated power of 22 dBm.
The objective of this testing was to evaluate Wi-Fi HaLow’s real-world performance using standard equipment in challenging conditions.
The theoretical maximum range of the system, calculated based on the IEEE 802.11ah standard, is around 15.9 kilometers.
During the field tests, the team successfully achieved a throughput of 2 Mbps using User Datagram Protocol (UDP) at the maximum range, demonstrating that Wi-Fi HaLow can maintain a strong connection even at long distances while delivering usable data rates.
The Impact of Power Efficiency
One of the standout features of Wi-Fi HaLow is its power-saving capabilities. This technology can significantly extend the battery life of devices, particularly those powered by coin batteries, allowing them to operate for months without needing a change.
Such efficiency can be a game-changer for IoT devices deployed in remote areas, where access to power sources may be limited.
The Morse Micro team emphasized the value of their technology in practical applications, stating, “Our testing in Joshua Tree National Park demonstrates that Morse Micro’s Wi-Fi HaLow isn’t just about impressive numbers; it’s about delivering real value in environments where you need it most.”
This statement highlights the importance of reliable long-distance connectivity in diverse settings, from rural landscapes to industrial applications.
