Cisco was already the trusted provider of the company's Ethernet switches and routers for the
wired network which provided industry-leading reliability and connectivity to the desktop, as well as
integration of security, management, and wireless modules. The features of the Cisco Unified
Wireless Network met the company’s security needs while offering ease of management. The
centrally managed architecture has a lot of benefits, and there is less administration required than
under older wireless LAN deployment, because the configuration is all central and automated.
wired network which provided industry-leading reliability and connectivity to the desktop, as well as

Wireless Network met the company’s security needs while offering ease of management. The
centrally managed architecture has a lot of benefits, and there is less administration required than
under older wireless LAN deployment, because the configuration is all central and automated.
The new wireless network consists of eight Cisco 4400 Series Wireless Controllers along with over
450 Cisco Aironet 1130AG Series Access Points installed throughout the facility. The Cisco Unified
Wireless Network Architecture offers redundancy at several levels, at the RF level, the system
“self-heals” when one or more APs become inactive. The architecture also supports port
redundancy per controller and controller device redundancy. SAMC designed a wireless network
deployment that would support both wireless voice and data access anywhere in the facility. The
IEEE 802.11a,b,g Cisco Aironet 1130AG Series Access Points can be centrally managed with
Cisco 4400 Series Wireless LAN Controllers in high availability architecture along with the Cisco
Wireless Control System (WCS) management software. The Cisco WCS provides centralized
network management, security monitoring, and localization of rogue devices and automatically
associates each new access point with the controller, eliminating manual configuration and saving
many hours in maintenance time.

In addition to centralized management and rapid deployment of all of the access points, the Cisco
Unified Wireless Network offers segmentation of user groups. This feature enables SAMC IT staff
to configure separate virtual LANs for voice and data, helping to ensure both data security and
quality of service for voice traffic. Voice receives top priority to support the ability to roam
seamlessly from access point to access point without dropping a call. QoS and the reliability of the
network are further enhanced through support for Wi-Fi Multi Media (WMM), which prioritizes delay
sensitive traffic to provide uninterrupted service, and voice optimization.

Next-Gen Wireless-N clients for performance testing. The pilot
was set up to see if users could expect the same application performance on wireless as they enjoy
on the wired network. When the performance results were compared with 802.11a and 802.11n,
the 802.11n client performed seven times faster than the 802.11a client. The 802.11n client
achieved speeds of up to 165Mbits/sec and was able to download 2 simultaneous files, each 500
MB, in just about 2 minutes—65 percent faster than the 802.11a client. These phenomenal
performance results along with the enhanced reliability that SAMC was able to achieve with the
joint Cisco and Intel 802.11n solution will be leveraged throughout the facility in the future for
deploying bandwidth-intensive applications. “The Intel

Results
“Today, the Cisco Unified Wireless Network Solution is transforming the way our staff works at
SAMC. They can collaborate and communicate more efficiently, and even patients and visitors are
benefiting from secure, ubiquitous network connectivity using the Cisco guest access capability.
More importantly, clinicians at SAMC are already demonstrating the ability to use the ASCOM and
Cisco Wi-Fi phones over Cisco Unified Wireless Network anywhere in the facility, at the point of
