Success Case

Siza – Distributed Antenna System (DAS)

Netherlands

Siza offers support and care to people with a physical, mental or multiple disability and to people with autism or non-congenital brain damage. This care and service aims to enable clients to make their own choices as much as possible and live as independently as possible. Digitalization and (care) technologies form the basis for this.

From the moment plans were made in 2016 for the new building of Het Dorp, the independence of the clients was central to this as well. In a unique way, with all stakeholders and clients together, the needs were identified and solutions developed.

To facilitate the independence and flexibility of the clients, one of the specifications in the Plan of Requirements was that only mobile communication would be used: WiFi and 4G. In addition, sustainability was an important element in the construction and a determining factor in the choice of materials. However, many modern façade insulation materials keep out not only the cold, but also the mobile signals. As a result, mobile coverage in the new building proved inadequate. To solve this problem, Cellnex, in collaboration with the mobile network operators T-Mobile, KPN and Vodafone and domestic installer SPIE, implemented a so-called Distributed Antenna System (DAS). A DAS system is a modern technological solution that is highly scalable, where all available mobile signals from all operators are generated by a base station and brought into the building via distributed antennas.

Challenges

Sustainability was an important element in the construction and a determining factor in the choice of materials. Many modern facade insulation materials not only keep out the cold, but the mobile signals as well. As a result, mobile coverage in the new building proved inadequate.
Ensuring high bandwidth indoor connectivity. In order to facilitate the independence and flexibility of the clients, exclusive use of mobile communication, via WiFi and 4G was required.

Solution

Implementing a Distributed Antenna System (DAS) to improve indoor connectivity. A DAS system is a modern technological solution, in which the available mobile signals of all Dutch Mobile Network Operators (MNOs) are generated by a base station and brought into the building via distributed antennas.
