Wi-Fi HaLow Achieves 16 km Stable Connection

Morse Micro has conducted a series of tests of Wi-Fi HaLow technology in Joshua Tree National Park, USA. The goal of the testing was to explore the maximum range and performance of Wi-Fi HaLow under conditions of minimal interference. The trials demonstrated the ability to transmit data over distances of up to 16 km with significant bandwidth.

The test used a standard set of equipment: an access point based on the MM6108-EKH01, which includes the Wi-Fi HaLow MM6108 module and a Raspberry Pi 4. The equipment operated in normal mode with a transmitter power of 22 dBm. Morse Micro deliberately avoided using directional antennas or increased transmitter power to ensure the equipment could be used in portable, battery-powered devices.

The theoretical communication range was calculated using the Friis equation, taking into account signal loss at maximum distance. According to the calculations, the maximum range under ideal conditions was about 15.9 km, which meets the requirements of the IEEE 802.11ah standard. Morse Micro used a slot time of 52 microseconds, which made this result possible.

Practical testing confirmed the theoretical calculations: in the national park, a data transfer rate of up to 2 Mbps was achieved at a distance of 15.9 km.

According to Morse Micro experts, these results match the theoretical limits of the technology, making Wi-Fi HaLow ideal for applications such as agriculture and infrastructure projects in remote areas. However, in urban environments with high radio signal density, HaLow’s effectiveness may be lower due to interference.
