Challenge
Universitätsklinikum Essen (the University Hospital of
Essen) is one of the leading teaching hospitals in
Germany. Offering a wide range of modern
diagnostic and therapeutic methods and procedures,
the hospital’s research specializes in cardiology,
oncology, and transplants. With more than 1300
beds and 160,000 patients per year, the hospital is
also one of the largest healthcare facilities in the
country. “To remain at the leading edge of
healthcare, we constantly look for new ways to
improve clinical efficiency and communication
throughout our 50 clinics and institutes,” says Frank
Ressing, head of the Network and Data Center
Department at Universitätsklinikum Essen.

Universitätsklinikum Essen adopted wireless
technology early on to provide students and office
staff with mobile Internet access. In 2005, the
hospital was ready to extend the benefits of mobility
throughout its clinics, but needed to find a more
robust solution. “We knew that the standalone
access points that we had been using to create
Internet hotspots on campus didn’t provide the
bandwidth or security required to support clinical
applications,” says Ressing. Knowing that
government funding approval for a complete wireless
network could take years, Universitätsklinikum Essen
wanted to help ensure that the technology that the
hospital chose would not become obsolete by the
