Coverage Audits and Professional Radio Engineering
Secure your critical communication infrastructure with precision expertise. From on-site propagation studies to channel analysis, TRPS designs optimal solutions (DMR, WAVE 4G LTE, ATEX) to ensure the performance and compliance of your radio network. Based in Le Havre and Normandy, we operate throughout France and internationally.
Contact usOn-site audit: the end of dead zones
Radio coverage for an industrial site cannot be guessed; it must be measured. At TRPS, we have made a radical choice: supplementing software simulations with real-world field data. Why? Because an algorithm will never replace the impact of a metal structure, a reinforced concrete wall, or electromagnetic interference from your machinery.
. Propagation tests in real-world conditions:
We visit your site with a test kit and measurement devices. We grid every sensitive area—basements, technical rooms, storage zones—to precisely map signal reception. You get a coverage guarantee exactly where you need it most.

. Spectrum analysis and interference detection:
Radio is an invisible but saturated environment. We perform a spectral analysis to identify potential stray signals or neighboring networks that could degrade the clarity of your communications. This step is crucial to guarantee a "clean" signal without dropouts.

. Safety validation (Lone Worker Protection):
For your lone workers, a dead zone is a critical danger. Our audit specifically validates the transmission of Lone Worker Protection (LWP) alarms. We ensure that, wherever your employee is located, their emergency message will reach the base instantly.

Existing fleet audit: Rationalize your costs
Reorganizing workflows
- Analysis of the actual usage of your call groups and communication channels.
- Optimizing the number of frequencies to immediately reduce your ANFR fees.
- Optimizing internal organization to streamline communication between your teams (logistics, security, technical).
- Implementation of call priorities to ensure the availability of critical lines.
Technological decision-making
- Comparative profitability study between a network with physical relays and a WAVE PTX (4G LTE) solution.
- Coverage analysis: switching to 4G/Wi-Fi networks to eliminate heavy infrastructure maintenance costs.
- Assessment of interconnection needs (Radio to Smartphone or fixed telephony via OmniConnect).
- Consulting on digital transition to ensure the long-term sustainability of your investments.
Hardware sizing
- Audit of your device fleet: ensuring the right balance between used functions and chosen models.
- Budget rationalization: recommending agile models truly tailored to your needs
- Monitoring the condition of batteries and accessories to reduce the rate of premature replacement.
- Standardizing your fleet to simplify inventory management and after-sales maintenance.
Regulatory support and ANFR authorization
The use of professional radio frequencies is subject to strict regulations. Don't let administrative procedures slow down your project. TRPS supports you from A to Z in bringing your network into compliance and acts as your direct liaison with the National Frequency Agency (ANFR).
. Engineering documentation for frequency acquisition:
Every private radio network installation requires a frequency usage authorization. We conduct the essential preliminary technical study for your application: calculating antenna heights, transmission power, and radiation patterns. A well-prepared file is the key to rapid approval by the authorities.

. Annual fee optimization:
Did you know you pay fees for every frequency and relay used? As part of our audit, we analyze your ANFR fees. Our goal is to streamline your fleet so you only pay for what you truly need, by removing obsolete channels or optimizing your network architecture.

. License monitoring and renewal:
Authorizations are time-limited. TRPS monitors your frequencies to prevent any service interruptions or legal risks associated with unauthorized use. We manage renewals and technical modifications (adding terminals, changing technology) for you throughout the lifespan of your installation.

Our methodology: A structured approach for a flawless network
Step 01 | Diagnosis & Analysis
The concept: We conduct a comprehensive technical audit of your current communication workflows. We analyze the number of simultaneous users on-site and identify your regulatory safety constraints, particularly for ATEX-zoned environments or specific requirements for lone worker protection (LWP) devices.
The goal: To establish a precise and rigorous set of specifications for your future professional radio infrastructure.
Step 02 | On-site Measurements & Testing
The concept: We visit your site to test signal propagation in real-world conditions using our measurement equipment. We precisely identify all structural obstacles (reinforced concrete, basements, dense metal structures) that could degrade your signal.
The goal: To permanently eliminate dead zones and guarantee 100% indoor and outdoor radio coverage across your entire site.
Step 03 | Engineering & Recommendations
The concept: Based on data collected in the field, we design your network's technical architecture. We select the ideal technology (digital DMR network or WAVE PTX hybrid solution) and plan the placement of relays and interconnection gateways.
The goal: To build a custom, scalable radio system that is fully compliant with ANFR standards while optimizing your financial investment.
Step 04 | Report & Deployment Plan
The concept: We provide a comprehensive engineering package, including theoretical coverage mapping, a precise network diagram, and the programming protocol for your fleet of professional two-way radios prior to delivery.
The goal: To provide you with full visibility into your future network's performance and plan a seamless rollout with zero downtime.
