Product Overview

The PanelBridge is one of the industry’s fastest unlicensed backhaul solutions. It’s ideal for short to mediumrange relay and tower links, custom-engineered collocation, and unlicensed 5.15-6.425 GHz spectrum. Leveraging the latest wireless technologies and the new 6 GHz band, the PanelBridge achieves low latency and speeds up to 4.5 Gbps, with advanced interference mitigation ensuring high reliability.

WIS OS

The full-featured operating system makes the devices ideal for WISPs and operators, enabling low latency and high packets-per-second performance.
The QoS (Quality of Service) mechanism prioritizes mission-critical data and ensures efficient transmission of real-time traffic, such as voice and video.
Essential tools-such as a spectrum analyzer, device discovery, and antenna alignment-are included.
