INTRODUCTION

RomARS, through its own product, offers a new generation of integrated private 5G + Wi-Fi networks, designed to provide businesses with secure, seamless, reliable and high-performance connectivity in industrial, logistics, healthcare, cultural heritage and corporate settings.

The solution is based on an N3IWF Gateway that enables access to the Core network through both the 5G mobile network and Wi-Fi infrastructure.This integration – “5G” via Wi-Fi – makes the RomARS offering distinctive and innovative in the Private Network market.

OVERVIEW

Why Choose a Private Network

A private network allows you to have full control over your company’s 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 critical environments;
  5.  full control over the management of your own applications.

The Advantage of 5G+Wi-Fi Integration

With our solution, it is possible to combine the benefits of 5G with the simplicity and affordability of Wi-Fi:

  • advanced security and centralized management typical of 5G;
  • reduced user terminal costs;
  •  use of Wi-Fi access points as access points to the 5G core network;
  • rapid deployment on existing infrastructures;
  • comprehensive coverage of environments (indoor and outdoor) and low-cost implementation;
  •  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, including Release 15 untrusted mode via N3IWF and 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 sizing;
  • system configuration and customization;
  • integration with existing infrastructures;
  • development of dedicated features;
  • turnkey management of the entire project.
