Customer Case Study 
parts of the 900,000-square-foot facility, supporting a combination of ASCOM
®
 i75 phones and 
Cisco
®
 7920 Wi-Fi Phones. The legacy deployment did not support inter-subnet roaming and real-
time radio frequency (RF) control of the access point for deployment and management of advanced 
mobility services such as voice. Each access point in legacy deployment had to be configured and 
managed independently. While this architecture was adequate for providing WLAN connection in 
limited areas for SAMC initially the deployment could not scale to support the entire facility and the 
business imperatives they needed in the future in an efficient and cost effective manner.  
In addition to the needs of providing ubiquitous mobile IP voice throughout the facility, SAMC 
needed to provide its clinicians with bedside charting, order entry and drug administration 
applications. For the plant services and purchasing departments they needed the ability to have 
access to inventory management applications. Although the planned deployment held the potential 
to empower caregivers in many new ways, the clinical tools would also place greater demands than 
ever before on hospital information systems. In particular, clinicians would need unprecedented 
mobility to be able to access patient records and clinical applications from anywhere in the center, 
including at the bedside. That capability would require an extremely robust, highly secure, and 
pervasive wireless network and one that is easy to manage while maintaining lower total cost of 
ownership. 
Solution 
The SAMC decided to migrate its existing wireless network to a Cisco Unified Wireless Network, a 
centrally managed controller based architecture for simplified management and enhanced security 
and to support fast secure roaming and the latest voice features such as 802.11e (quality of service 
[QoS] standard for multi-media traffic). The SAMC team embarked on the project by conducting a 
thorough site survey using Airmagnet and Cisco Spectrum Analysis tools to identify potential 
interference problems and optimize the network infrastructure to support delay sensitive 
applications such as Voice. Cisco Spectrum Analyzer supports real-time spectrum intelligence to 
detect, classify, and locate non Wi-Fi sources of RF interference in the unlicensed 2.4-GHz and 5-
GHz bands. Quickly detecting and mitigating RF interference improves coverage, capacity, quality 
of service, and security of the wireless network.
