DAS – Optimal Indoor Coverage

In situations where every second counts, it’s absolutely imperative that all public safety services can communicate with each other directly. All public emergency services communicate with their own C2000 network, which only they can access. Flash connects systems to amplify the signal as a system integrator and thus allowing communication on the C2000 network at difficult locations where accessibility is not always a given, such as shopping malls, high residential/commercial towers, car parks or tunnels.

Blind Trust

Police forces, fire brigades, emergency medical services and other organisations that play a major role in public safety, must be able to blindly trust their mission-critical communication, both within their own organisation and in cooperation with other organisations. This is true not only in challenging locations and remote buildings on factory sites, but also in crowded stadiums with high data traffic or in secured locations during a major event or in an amusement park. After all, accidents can happen at any time.

Guaranteed Connectivity In Every Space

In some spaces, there may be insufficient or no coverage of the communication network at all, which means losing the connection. This happens often in tunnels, underground car parks and other buildings where network coverage is hampered by the material used (e.g. concrete, steel and coated glass) or simply because of the location itself. Some examples are the coverage in the buildings on the extended campus of Delft University of Technology, the steel structures in the buildings of the Efteling amusement park, the KilTunnel, the Amsterdam Court, and so on. A guaranteed network then becomes crucial.

DAS – Optimal Indoor Coverage

With a Distributed Antenna System (DAS), all HF signals can be distributed via a single (active or passive) antenna system and the desired indoor coverage is achieved with just one system.

It’s not just public safety services that experience problems with mobile phone coverage in their buildings, companies do too. This is often caused by the use of increasingly effective insulation or materials that are difficult to penetrate. It’s becoming increasingly difficult for the providers’ signals to reach the buildings, so a Distributed Antenna System (DAS) is a great solution. With a DAS, indoor coverage is optimal. Not only does a DAS distribute the RF signals for two-way radios and pagers throughout the building, but also all signals from all Dutch providers and operators. This means guaranteed optimal reach and coverage, always.


One integrated network for mobile telephones, two-way radios, radio-paging, C2000 and other signals, resulting in cost savings and provider independence!
Traditionally, a separate network is created for each HF (High Frequency) signal in buildings and offices. Thanks to a DAS, this is no longer necessary. Using the DAS, all possible HF signals are distributed and the desired indoor coverage is achieved. Thanks to our years of accruing knowledge and experience with all types of wireless networks, we are able to provide indoor network coverage for analogue, TETRA and DMR radio networks, 2G/GSM, 3G/UMTS, 4G/LTE, FM and DAB, among others.

Public And Private Indoor Coverage

There is a difference between indoor coverage for:

  • C2000 public order and safety;
  • Other non-POS related systems.

The solution depends entirely on the demand and the existing system and we have already installed the DAS indoor coverage in many places. For example, court buildings, large residential towers, car parks, tunnels, police stations, correctional facilities, but also in the secured buildings of amusement parks, shopping malls and factory grounds.
