How the DC-UPS ADEL System keeps a Wireless Network alive.

What prompted an independent Wi-Fi provider to choose a DC-UPS for its applications?

Progetto8 is a company founded by 3 technicians who, armed with passion and kindness towards others, are able to understand the real problems of the population.

Bringing Wi-Fi, in particular, in mountainous or hard to reach areas where large corporations do not arrive is a major problem today.

The challenge of Progetto8 is precisely that of giving wireless coverage in the so-called "forgotten by all" areas, places where it is difficult to find coverage for the cell phone.

The first plant was installed in 2007 in the furthest mountain municipality from the city of Piacenza, Ottone. The municipality has about 500 inhabitants and the new Wireless network is their only hope for being connected to the globalized world.

The project takes momentum and in a short while the coverage reaches most of the province of Piacenza and part of the province of Pavia.

Over the years there have also been awards and partnerships at Italian and European level.

The creation of Wi-Fi networks in urban areas is now a developed concept, but the biggest challenges are in the industrial and agricultural areas.

The development and implementation of Wi-Fi networks in these areas are entrusted to private companies which are based on regional laws to develop the National Digital Agenda.

For the construction of the facilities, is common practice to use public administration locations, such as sports facilities pylons for lighting, radio repeaters, cell phone repeaters or buildings up to 40 meters above the ground, which usually make up the highest point in the city or of the area to be connected.

The use of these structures for the installation of the Base Station offers the solution to three major problems:

1) Avoid the installation of new, very expensive trusses.

2) Bring the Base Station closer to the users, improving the received signal.

3) Operate without renting private facilities, avoiding increasing the risk of environmental impact.

What, however, is the greatest concern in these plants?

In these areas, keeping the current intact even in the case of Black-Out is essential!

The service offered by small providers such as Progetto8 must align with the high-end competition in Italy: low latency, low jitter, high guaranteed throughput, high service availability, transparent management via web portal on one side and low cost of the offer on the other, to allow access to the broadband connection even to small and medium-sized businesses in the area.


In the case of Progetto8 the radio routers are powered by direct current but are equipped with isolation transformers. In the case of connection cable lengths greater than 15m, it was preferred to use 48V power supplies instead of 24V, to optimize the current voltage ratio.

As regards the power supply, electrical uninterruptible power supplies are used to compensate for the occasional power failure and to guarantee service continuity for a few hours.

Being a very efficient and performing wireless broadband network, it must always be connected. Here comes the CBI2410A of ADEL System to ensure electrical continuity.

The following is a demonstration of how the DC-UPS ADEL System is at the centre of the structure's energy support base system.



The management of the batteries, which must guarantee 24 hours a day the continuity of operation to the network in case of interruption and / or malfunction of the electricity network provided by the energy manager, is a basic element of the quality and safety of a network of connectivity.

To limit the effects of network transients (lightning surges, industrial loads, etc.), the system mounts an isolation transformer, a system of surge arresters, a self-starting differential and a 16A and a 6A magnetothermal switch for two parts of the system which is also equipped with a fan heater to limit thermal problems.

Here the Battery Care philosophy of ADELSystem is strategic, increasing the duration of the 2 batteries, in this case from 100 Ah, thanks to the multiple types of recharging available in each CBI unit. Battery aging adaptability algorithms and battery testing function are essential for accurate diagnosis.

Each CBI detects the entire impedance of the battery, the element in short circuit disconnected from the battery if completely discharged.

These are some of the functions that allow the system to be more reliable over time.

Thanks to the DC / DC converter it is always possible to realize different voltages on the 24V load output always supplied in the ADELSystem range.

Progetto8 summarized the following points on why they chose the ADELSystem products:

  • We supply the power to the load and manage the battery with a single device
  • With a single device we back up the system
  • Batteries are charged and tested in order to extend the service life (over time) of the batteries
  • The battery diagnosis system, allows you to monitor them in Real Time and to warn in advance if they are no longer able to be efficient
  • With the new CBI2801224A product it is then possible to make a remote diagnosis via Modbus of all the system analysis parameters by monitoring the site remotely.
  • Very high-performance application with very limited costs.
