Aircraft 3D RF Cabin Modelling

Aircraft 3D Cabin Modelling image


The aircraft provides a every unique RF environment that takes very careful planning when deploying wireless technology (WiFi, GSM, LTE, etc.) on-board.

Here at Frequencia we have developed and invested in the technology that allows us to accurately predict and plot the RF environment based on theoretical and practical experience gain over the last 15 years of working in the field.

We have the tools that allow us to determine the spacing and frequency assignment for each wireless access point such that we can optimise for cabin coverage whilst, managing co-channel interferences issues caused by the lack of spatial separation within the cabin.

Frequencia PED / STC Services

PED – Connectivity – Compliance – Certification

Throughout the next decade, the majority of new aircraft being delivered into commercial revenue service will have connectivity capability and existing aircraft fleets will be upgraded through the PED testing process.

The Frequencia engineering team have an extensive background in PED testing and can adapt their services to meet all clients’ requirements. Frequencia engineers have been involved with PED compliance since 2006.

STC Process Overview

  • Definition of certification plans, including T-PED assessment process
  • The T-PED assessments follows RTCA DO-294, DO307 and ED-130
  • EASA Certification Review Items (CRI’s)
  • T-PED analysis includes:
    • T-PED technology and usage scenarios
    • T-PED Interference Scenarios
    • Aircraft configuration characterisation
    • Multiple Equipment Factor modelling
    • Aircraft and avionics susceptibility characterisation modelling

Depending on T-PED analysis results, T-PED testing is performed to verify the equipment’s immunity.

With Frequencia’s proven skill, experience in this field and agility to respond to our customer’s needs, one of the market leaders in this field.
