INTRODUCTION

RomARS introduces a new generation of integrated private 5G + Wi-Fi networks, designed to provide businesses with secure, reliable, and high-performance connectivity in industrial, logistics, healthcare, and corporate environments.

The solution is based on a N3IWF Gateway enabling the access to the Core network through both the 5G mobile network and Wi-Fi infrastructure. It is precisely this integration – “5G” via Wi-Fi – that makes the RomARS offering distinctive and innovative in the Private Networks market.

OVERVIEW

Why Choose a Private Network?

A private network enables organizations to have full control over corporate communications, ensuring:

  1. greater security for data traffic and device access;
  2. direct control over performance and quality of service;
  3. high operational reliability;
  4. continuity of communications in mission-critical environments.

The Advantage of 5G+Wi-Fi Integration

With RomARS, it is possible to combine the benefits of the 5G world with the simplicity and cost-effectiveness of Wi-Fi:

  • advanced security and centralized management typical of 5G;
  • educed user terminal costs;
  • use of Wi-Fi Access Points as access stations;
  • rapid deployment on existing infrastructures.
  • Integration with a dedicated 5G network or a dedicated Slice on a public network

Key Features of the RomARS Solution

  1. Integration with the 5G Core: native solution with integrated 5G Core or full interoperability with the main 5G Cores available on the market.
  2. Wi-Fi Access Module: support for 3GPP standards for non-3GPP access:
    • Release 15: Untrusted mode via N3IW
    • Release 16: Trusted mode via TNAP and TNGF
  3. ATSSS Available: intelligent traffic management with simultaneous and optimized use of 5G and Wi-Fi networks.
  4. Intuitive Graphical Interface: simple and user-friendly GUI for system configuration, monitoring, and management.

The Added Value of RomARS

  • network design and dimensioning;
  • system configuration and customization;
  • integration with existing infrastructures;
  • development of dedicated functionalities;
  • turnkey management of the entire project.
