Description

IEEE 802.11ah, also known as “Wi-Fi HaLow”, provides a Wi-Fi implementation in sub-1GHz frequency ranges. Due to its lower operating frequency than traditional Wi-Fi, Wi-Fi HaLow trades diminished data rates for longer transmission distances. This balance is favorable to internet-of-things (IoT) and other long-range applications. Despite these benefits, commercial implementations of HaLow are not as ubiquitous as other IoT protocols such as IEEE 802.15.4, LoRa, or Wi-Fi. This talk aims to explore 802.11ah and strives to create a first-of-its-kind open-source implementation of the protocol in GNU Radio: "gr-halow". Live analysis of communication between two commercial Wi-Fi HaLow modules will provide an intuitive understanding of HaLow’s functionality and capabilities. The talk will also demonstrate whether a computer, connected to an SDR and running GNU Radio, will be able to appear as a third client on the network. The open-source code base for gr-halow is still in development, but exploring the progression of the out-of-tree module will enable researchers, developers, and hobbyists to experiment with 802.11ah-based solutions using SDRs without the need to rely on commercial hardware implementations.
