Wireless Networks

Notes system (IDS), improved detection of rogue access points, as well as the security features
Wi-Fi Protected Access (WPA2) and wireless network admission control (NAC).
Result
As of late 2006, the WLAN upgrade was complete for the Cisco headquarters campus in
San Jose, California, and deployment was under way in other locations. With nearly 40
percent of Cisco employees working at the headquarters site, the early results achieved at
this campus indicate the value to be obtained from the remaining deployments.

With the next-generation WLAN and Cisco Unified Wireless Network solutions, Cisco
employees will experience a better wireless network. In addition, Cisco will gain the
benefits of cost savings, greater network stability, and continued productivity gains.

Lessons Learned
Cisco customers can benefit from the lessons learned by Cisco IT during the initial WLAN
deployment and the next-generation upgrade.

Regulatory issues. Different access points and wireless interface cards are required in
certain parts of the world because the 802.11a standard may not be approved in some
countries, or not yet approved in its most recent version. Particularly in emerging market
countries, regulatory requirements are more complex, and wireless standards are more
controlled. As a result of these issues, Cisco has not been able to use the same access
point model in every country. This difference has not significantly affected the support
requirements or benefits achievable from the new WLAN.

Transition resources. Certain operational and support resources were required during the
deployment of the new WLAN solutions. During the architecture and design phases of the
project, several network design engineers created and tested the design, and all required
documentation using local and remote labs. In addition, several network operations
engineers implemented the proposed design at pilot sites for limited-duration tests and
Cisco network management personnel created the interface to Cisco IT's internal network
management systems. Additional Cisco IT staff created technical documentation and
conducted training globally for the implementation and support engineers.
During the implementation phase, several project managers monitored the implementation
schedule and activity. The installation of the new wireless equipment was performed by
both Cisco employees and outsourcers.
Indoor and outdoor deployments. Cisco IT developed separate deployment plans for
indoor and outdoor coverage, reflecting differences in scope, architecture design, and user
needs and expectations for service levels. Upgrading indoor coverage was given a higher
priority than installing new outdoor access.
Questions:
1. Study and analyse the case.
2. Write down the case facts.
3. What do you infer from it?

5.6 Summary

A personal area network - PAN - is a computer network organized around an individual person.
Personal area networks generally cover a range of less than 10 meters (about 30 feet).
