Solution
As part of the government proposal process, Universitätsklinikum Essen tested five wireless
solutions, requiring each vendor to build a demo pilot. Based on a centralized WLAN infrastructure
that used two controllers and up to 15 access points, the individual pilots tested the security,
management, and flexibility of each solution. Cisco deployed a pilot of its Unified Wireless Network
in the hospital’s radiology department. “All features of the Cisco Unified Wireless Network,
especially the security capabilities, integrated perfectly with our existing Cisco infrastructure,” says
Ressing. “Besides providing the right capabilities, we liked the advantage of working with one
proven vendor, which would save us additional time and money.”

Once Universitätsklinikum Essen selected the Cisco

Unified Wireless Network, Ressing began
discussing the possibility of using 802.11n technology. Even though the technology was not on the
market yet, Ressing was convinced that adopting 802.11n as soon as it was available would
protect the investment of the hospital in the future. “Cisco shared its roadmap with us, designed an
802.11 a/b/g network that we presented to the government for funding, and committed to changing
our access points to 802.11n as soon as they became available,” says Ressing. “Cisco was a true
partner.”

After receiving government funding in 2008, Universitätsklinikum Essen began deploying the
802.11n network. Today, the network is nearly fully deployed in the main hospital buildings, giving
doctors, staff, and students mobile Internet and network access. To incorporate mobility into its
clinical processes, Universitätsklinikum Essen began with one building as its test bed.

The introduction of the first mobile ward in the hospital caused positive changes in traditional
clinical process workflow. Using laptops, tablet PCs, and PDAs, doctors and nurses now record
and access data directly at the patient bedside, saving time and increasing accuracy. Healthcare
givers also use PC carts to review lab results and radiology film right from their patients’ rooms.
“The 802.11n network supports all a, b, and g clients, making our transition to mobile patient care
smooth and easy,” says Ressing.

Universitätsklinikum Essen also uses Cisco’s Unified Wireless Network in conjunction with its
Drager and Phillips patient monitoring systems. Through the Cisco Compatible Extensions
Program, both vendors’ systems are certified with Cisco, helping to ensure transparent
interoperability and reliability between the mobile equipment and network. “Thanks to the Cisco
Unified Wireless Network, our doctors and nurses can now continue to monitor breathing and heart
rates if we need to move patients between rooms,” says Ressing. “The mobile monitors transmit
this vital data to our caregivers via the wireless network in real-time.”

The advanced security features of the Cisco Unified Wireless Network are critical for
Universitätsklinikum Essen. “We’ve created 120 VLANs within the network, keeping each
department, clinic, and user group within the hospital separate,” says Ressing. When a user logs
in, the network authenticates against the RADIUS server based on pre-defined user group policies.
“Each user is automatically brought in to the correct VLAN,” he says. “This also makes it easy for
us to provide secure guest access to patients and visitors.”

Results
The Cisco Unified Wireless Network is helping Universitätsklinikum Essen to improve efficiencies in
its clinical processes, increasing caregiver productivity and patient care. “Cisco enables us to
introduce completely new workflow processes that focus around the patient,” says Ressing. In the
past, doctors handwrote their notes at the patient bedside and later entered the information into a
