FreeWave’s ZumLink IQ offers the ultimate in ease of operationalization for IIoT gains, giving you IQ compute power, storage, and wireless communications links all in a single, hardened hardware product.

With ZumLink IQ, you can run edge applications and create a wireless network using the unlicensed 900 MHz spectrum and Frequency Hopping Spread Spectrum (FHSS) technology: an inherently secure, cost-effective long-range alternative to Bluetooth, Wi-Fi, or LTE. Our ruggedized ZumLink radio supports high speed data rates with throughput from 80 kbps to 4 Mbps, with RF enhancement via FreeWave’s Network Accelerators.

The addition of FreeWave’s IQ Application Environment onboard makes it ready to run any number of industrial applications that put sensor queries, analytics, and intelligence at the network edge.
