Overview

Wi-Fi HaLow adapts the familiar Wi-Fi standard to a frequency and connection style that is ideally suited to the Internet of Everything. Operating in the sub gigahertz range, this standard delivers 1km range in point-to-point links and > 1km in 2-hop relays. By using a token-ring style of client management, a single HaLow access point can completely support up to 8191 clients, and provides adaptive bandwidth to each client based on their identified data transport needs.
