The CSL Router delivers instant, secure 4G connectivity tailored for diverse Internet of Things (IoT) applications. Designed for mission-critical environments, it provides reliable communication in locations where wired broadband is unavailable, impractical, or slow. By connecting through CSL’s private mobile APN network, the router establishes a secure data pathway that bypasses the public internet, ensuring that sensitive information remains protected at all times.
Secure and Reliable Connectivity
CSL IoT Routers are engineered to deliver dependable 4G connectivity for mission-critical operations. They ensure seamless data transmission, even in areas with unreliable or nonexistent fixed-line internet. This makes them ideal for IoT deployments in industries such as security, healthcare, and utilities, where uninterrupted communication and system uptime are essential.
Each router is supplied with a CSL roaming SIM, designed to maintain connectivity across multiple mobile networks. Utilising 4G networks, the routers automatically switch to the strongest available signal, maintaining continuous operation in all conditions.
Dual SIM and Backup Options
For maximum resilience, CSL offers a dual SIM variant, allowing the router to connect via two independent mobile network providers. This redundancy significantly enhances uptime, guaranteeing the highest level of availability over mobile networks.
In addition, the CSL Backup Router provides a dedicated 4G backup solution to complement existing broadband services. Acting as a failover link, it ensures that if a primary fixed-line connection fails, the network remains live through a secure mobile connection. This approach safeguards connectivity interruptions, ensuring business continuity for critical systems such as CCTV, alarm monitoring, and telecare applications.
Simplified Management and Deployment
CSL Routers are available as self-monitored or ARC-monitored solutions, depending on operational requirements. Remote access is enabled through Cisco AnyConnect, allowing secure direct connections to any device linked to a CSL Router.
All models are pre-configured and arrive ready for immediate deployment, significantly reducing installation time. They are supplied with a monthly data SIM bundle, enabling predictable cost management and streamlined network administration.
Technical Specifications
The CSL Router supports 4G connectivity across multiple frequency bands — 800, 900, 1800, and 2100 MHz for 4G, and 900 and 2100 MHz for 3G — delivering robust nationwide coverage. Depending on the model, routers feature dual Ethernet ports supporting data speeds up to 10/100 Mbps.
Built for durability, the device operates within a wide temperature range of –40 °C to +70 °C, making it suitable for harsh industrial and outdoor environments. Optional Wi-Fi capability, available with an aerial pack, further extends flexibility in installation and device connectivity. Dual-SIM and SIM-roaming features enhance redundancy and coverage reliability.
Security and Data Integrity
Security is central to CSL’s design philosophy. The routers operate on private Access Point Names (APNs), ensuring data travels securely within CSL’s private network infrastructure. All data traffic is encrypted and continuously monitored to prevent unauthorized access or tampering.
These measures make CSL Routers particularly suited for applications demanding high data integrity, such as alarm signalling, healthcare monitoring, and energy management systems.
Case Studies
Explore three real-world deployments that demonstrate how our solutions perform in demanding environments:
- In the case of Thames Water, working alongside Vodafone Business, we supported their digital-transformation project by delivering secure, dual-managed connectivity to around 3,500 telemetry sites ahead of the PSTN switch-off – you can read the full story here.
- For Eolas Technologies in Ireland, the challenge was remote maintenance of emergency-lighting systems across over 150 sites with diverse coverage needs. We deployed our dual SIM 4G routers within a “Hub & Spoke” architecture to provide private network access, centralised visibility and high resilience – read more here.
- In the retail security domain, Smoke Screen leverages our IoT routers to connect its network of security-fog systems across multiple stores. With secure remote access, dual SIM resilience and fast deployment without waiting for fixed-line internet, the solution helped reduce theft rates significantly – full details here.
Summary
Combining instant 4G connectivity, advanced security, and dual-network resilience, the CSL Router provides a robust and scalable platform for IoT and critical communication solutions. Whether deployed as a primary connection or as a backup to fixed broadband, it delivers the reliability and protection essential to today’s connected environments.
