Powerful Cellular and WiFi Connectivity

The SR500 line supports:

- 4G LTE CAT4 providing up to 150Mbps down/50Mbps up for high-bandwidth applications

- Optional 1.8GHz private LTE with 1000m range for campus and industrial park coverage

- 802.11b/g/n WiFi with internal or external antennas for local wireless access

This enables combining long-range cellular and short-range WiFi in one router.

Advanced Networking Features


SR500 routers provide:

- 2 x 10/100Mbps Ethernet ports for wired connectivity

- Extensive VPN protocols like IPsec, OpenVPN, GRE for secure remote communications

- SD-WAN capabilities to optimize performance across multiple links

- TR-069 and SNMP management for auto-configuration and monitoring

Tailored for Industrial IoT Projects

Typical applications include:

- Connecting PLCs, RTUs, sensors, meters and other assets to cloud platforms

- Enabling public WiFi and smart city services like traffic control and surveillance

- First responder networks with cellular and failover WiFi

- Deploying SD-WAN to combine multiple network links

- Adding cellular connectivity to sites without wired internet access

Customizable Linux Platform

The SR500 runs OpenWrt Linux allowing full customization. Development guides help tailor routers to specific use cases.

Centralized Management for Scalability

Star Device Manager (Star Cloud) enables managing entire networks of routers for simplified provisioning and monitoring. With industrial-grade reliability, the SR500 series provides connectivity assurance for critical industrial IoT.
