One of Robustel’s unique value propositions is its device management platform called RCMS (Robustel Cloud Manager Service). RCMS offers real-time monitoring, configuration, and troubleshooting across thousands of deployed devices – reducing onsite visits and service costs considerably.
What is RAD?
RAD (founded in 1981 in Israel) is a veteran of the telecommunications world. It’s recognized for its mission-critical networking gear, particularly in service provider and enterprise-grade environments. RAD positions itself as a leader in industrial IoT backhaul solutions, network edge virtualization, and private networking for critical infrastructure providers.
Key solution offerings include:
- Industrial IoT (IIoT) Gateways
- Operational WAN connectivity for utilities and transportation
- Security-Hardened Devices for public and private sector infrastructure
- Edge computing and service demarcation solutions
RAD primarily serves telcos, railway operators, power grid suppliers, and government bodies through highly secure, reliable, and standards-compliant devices. Major strengths lie in redundancy, bandwidth management, multi-domain integration (IT/OT), and Smart SFPs (pluggable miniature modules) for Ethernet access.
