RAK7285/RAK7285C WisGate Edge Ultra Datasheet
Overview
Descriptions
RAK7285 WisGate Edge Ultra is the latest version of the RAK WisGate Edge series, designed to overcome the limitations of half-duplex communication. It's tailored to meet the demands of high-density network deployments, particularly for smart city infrastructure, metering applications, and other scenarios requiring reliable two-way communication at scale.
This gateway supports up to 8 LoRa channels in full-duplex (a 16-channel variant is coming soon), with multi-backhaul options including Ethernet, Wi-Fi, and Cellular connectivity. Its integrated advanced cavity diplexers not only provide exceptional out-of-band interference suppression but also provide lightning protection for the LoRa antennas, ensuring uninterrupted and secure full-duplex communication.
In addition, RAK7285 operates under WisGateOS 2, which is built on the latest OpenWrt kernel. The OS Web UI features a new design and supports multiple extension installations, enabling remote management using WisDM for personalized gateway customization.
