On 22 January 2025, the “2nd Wifi HaLow in Europe Workshop” took place at the ZHAW School of Engineering in Winterthur, Switzerland. Wifi HaLow is specially designed for IoT and smart devices. It offers significantly greater range than conventional Wifi standards, as well as higher data rates than other wireless technologies for large-scale IoT networks. During the "2nd Wifi HaLow in Europe Workshop”, the following practical results from ongoing university projects were presented.

  This presentation will showcase the findings and insights gained from tests conducted with the Newracom NRC7394 Wifi HaLow SoC using a point-to-point link between two evaluation kits. In the first part, measurements on signal bandwidth, duty cycle, data rate, and link budget (sensitivity/range) will be presented. The second part focuses on the system’s real-world performance in buildings and in urban outdoor environments.

  With Wifi HaLow (IEEE 802.11ah) devices from Anjielosmart, it is possible to achieve outdoor data rates of over 1 Mbps at distances of approximately 1 km, while complying with European regulations. Thanks to an integrated relay function, 2-hop routes are also possible, with one device functioning as both STA and AP. This study examines how seven devices can be positioned so that an eighth, mobile device can establish an IP connection to the root device from anywhere in the coverage area. Data rate, MCS, RSSI, and energy requirements were recorded in three different outdoor environments (field, forest, city).

  A master’s project at Fachhochschule Vorarlberg (FHV) aims to develop a Wifi HaLow Smart Meter adapter with an M-Bus interface from scratch. By the time of the presentation, initial hardware and radio tests have been completed. The speakers report on the challenges encountered during the development and setup processes, as well as present the first results of radio and power consumption tests.
