Case study

Secure and Efficient Communication to the Benefit of the Patients

Security, Unified Communications
Participating Company: 
Ascom Wireless Solutions

When the frequencies previously reserved for analogue wireless telephony were released for other purposes by law in 2006, the Stephanshorn clinic had grounds for concern that communication would be disrupted by external devices (32 different alarms were transmitted on the previously used analogue Ascom CTS 900 system). They needed a new system that could comply with the high security standards of a hospital and that was capable of integrating the existing systems. After in-depth discussions, the team responsible for the project rejected the proposed Voice over WLAN solution. One reason for this was that a system based on this type of solution would not have been able to ensure the signal coverage needed for secure communication and the various alarms. A “hybrid solution” was the strong favourite - a non-blanket coverage WLAN with 22 dedicated access points is used for mobile data communication (e.g. internet access for the patients, the future patient management system and electronic activity recording in the rooms), whereas mobile telephone communication and alarm management runs on the blanket-coverage IP-DECT system with its 26 access points. Various different providers were evaluated and only the Ascom IP-DECT system was able to guarantee secure information transfer. The hospital management was won over by the following features. The reliable, networked transfer of information on the existing paging system and the DECT units The excellent level of system availability The extremely robust units Excellent protection of investment (digitalisation of the existing analogue system facilitating enhancement of its capabilities; integration of existing, well-established functionalities; seamless assimilation of the various alarms run by the old system)
