IEEE 802.11ah (HaLow) Dongle for Simplified IoT Wireless Networking

Abstract

This demo presents design, implementation, and performance analysis of an IEEE 802.11ah (HaLow) dongle that provides license-exempt sub-1 GHz wireless RF channel, and USB (universal serial bus) interface for power supply and wired data link for easy Internet of Things (IoT) wireless networking. The presented HaLow dongle is implemented using TI CC1352P1 sub-1GHz smart RF chipset that can provide 50Kbps ∼ 4Mbps in 10m ∼ 1 Km distance range. It provides merits of i) flexible Tx rate/power adjustments and channel selection with minimized interference to maximize throughput for massive IoT devices, ii) user-friendly API (application programming interface) for raw-socket-based easy application implementations for various IoT services, and iii) simplified installation using USB interface for both data exchange and power supply. This demo presents the details of the IEEE 802.11ah (HaLow) dongle, and its performance analysis results in practical environments.
