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.

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.
