Exploring our services

Clear CinCom offers services focused on designing, optimizing, and improving radio mobile communication networks. This can include network planning, frequency planning, capacity management and RF QoS testing.

Nominal Cell Planning

Nominal Cell Planning gives railway infrastructure managers a precise, data-driven blueprint for coverage and capacity—reducing rollout costs, accelerating time-to-market, and laying a scalable foundation for GSM-R, FRMCS and beyond.

Prediction Model Tuning

The Prediction Model Tuning service delivers highly accurate, railway-specific radio propagation models—calibrated with real-world measurements—to ensure reliable GSM-R and FRMCS coverage, reduce deployment costs, and meet stringent safety and QoS requirements.

RF QoS drive testing

With our RF QoS Drive Testing service we ensure railway communication networks meet EIRENE and UIC standards (SRS, FRS, Subset-093, O-2475, O-2875) by validating coverage, performance, and reliability in real-world rail environments—delivering compliance, safety, and cost-efficient operations.

Radio Network Optimization

Radio Network Optimization ensures GSM-R and FRMCS networks deliver seamless coverage, reliable handovers, and standards-compliant performance across every rail corridor—enhancing safety, reducing costs, and future-proofing operations.

Radio Network Validation

The Radio Network Validation service ensures GSM-R and FRMCS deployments meet EIRENE and UIC standards, with processes aligned to Notified Body requirements. We deliver end-to-end compliance testing and NoBo-ready reports—streamlining certification, reducing risks, and ensuring safe, reliable railway communications.

RF QoS troubleshooting

RF QoS Troubleshooting helps railway operators quickly identify and resolve performance issues in RF coverage, voice & data communication (Subset-093), and ETCS data links. We deliver root-cause analysis, compliance-ready reporting, and actionable fixes—ensuring safety, reliability, and uninterrupted rail operations.

ETCS Simulation Testing

For the ETCS Simulation service we use a bespoke in-house simulator to validate ETCS over TCP/IP in GSM-R and FRMCS networks. We replicate real-world and failure scenarios to assess latency, reliability, and compliance—reducing deployment risks, ensuring safety, and supporting a smooth roll-out of ETCS.

Our products

In railway communications, safety and reliability depend on measurable performance. That’s why Clear CinCom has developed a dedicated suite of products under the CCC Suite Railwise umbrella to verify both radio access networks (RAN) and end-to-end application performance—across circuit-switched and packet-switched GSM-R and FRMCS based environments.

ETCS Application Simulator

The ETCS Application Simulator provides a risk-free, standards-compliant environment to validate ETCS over GSM-R and FRMCS. By simulating real-world and degraded TCP/IP communication scenarios, it ensures reliability, safety, and performance before deployment—reducing costs, risks, and time-to-certification.

RF QoS Drive Test Platform

The RF QoS Drive Test Platform delivers standards-compliant, autonomous validation of railway communication networks. With self-recovery mechanisms and automated result uploads to the Railwise cloud platform, it eliminates the need for onboard technicians—saving time, reducing costs, and ensuring reliable ETCS and voice communication performance.

Traffic Generator

The Traffic Generator emulates real-world railway data traffic, from ETCS-like messages to mixed TCP/UDP, Iperf, and sFTP streams. With multi-modem, multi-session support and advanced automation, it enables operators to validate GSM-R and FRMCS networks under realistic load—ensuring reliability, compliance, and future readiness.

Cloud-based reporting platform

Railwise is Clear CinCom’s bespoke, cloud based platform for visualizing, analyzing, and reporting results from the RF QoS Drive Test Platform, the ETCS Application Simulator, and the Traffic Generator. It transforms raw measurement data into actionable insights, helping operators, infrastructure managers, and system integrators maintain safe, reliable, and compliant railway communication networks.
