Extension of radio signal in tunnels and buildings

The Scenario

With the development and spread of TLC technologies, the amount of data and voice traffic is constantly increasing, especially in crowded and complex access locations.

In addition, the evolution of mobile technology requires high performance in all kinds of environments: outdoors, inside buildings to ensure the best services in companies, hospitals,
stations, airports, stadiums, schools, shops and even inside special places such as road, rail and metro tunnels.

 

 

The challenge

In order to implement the applications made possible by the evolution of technology and to achieve the objectives of European and national digitisation plans, it is essential to ensure that the performance of radio services is optimal everywhere and in all conditions. Only in this way will businesses and citizens be able to reap the full benefits of technological evolution.

To this end, it is necessary to extend and enhance the radio signal within environments that by their nature are particularly complex, as they are full of electromagnetic interference and barriers that make signal propagation difficult.

The challenge posed by the customer requires the extension of radio coverage in environments with these characteristics, such as airports, railway stations and skyscrapers.

The technical solution chosen must be “invisible” and not alter the architecture of the buildings (most railway stations are historic buildings) and, since its implementation may cause deterioration or disruption of services to the public, it must be carried out quickly and effectively.

The solution

Our experience has enabled us to design radio signal extension systems with minimal environmental impact and in coordination with the competent authorities in cases of monumental, archaeological or landscape constraints.

In order to meet the customer’s requirements, we implemented the DAS systems (Distributed Antenna Systems is a network of antennas spatially distributed in indoor areas and connected to a radio signal source of several operators) taking into consideration all the problems that could be encountered starting from the technical and architectural solutions (the types of antennas and their positions are chosen to ensure minimum “visual” impact with authorisation from the relevant authorities), up to the scheduling of works that were carried out during times when the area was closed to the public (night hours) and without interrupting the operation of the facilities (air traffic, rail traffic, etc.).

DAS systems implemented in end-to-end mode include:

  • Genoa Porta Principe and Brignole Railway Stations

  • Airports of Milan, Rome, Naples, Bologna, Catania, Venice

  • New Maire Tecnimont Headquarters in Milan Porta Garibaldi – 2 towers 25 floors
