About The Customer
Cisco has a highly mobile workforce, where almost every employee is issued a laptop computer with a wireless interface card. This case study describes an upgrade of the internal wireless LAN (WLAN) using Cisco Unified Wireless Network solutions. Cisco cus
The Challenge

The challenge for Cisco IT was to continue providing a global wireless LAN that could serve as a primary access medium and deliver more bandwith and coverage to more users, while satisfying the company's business requirements. The next-generation WLAN would also need to provide native support for wireless video and voice, with high levels of accessibility, availability and security to reduce service-impacting incidents. 

The Solution

The Cisco Next-Generation WLAN program, which began in May 2006, will evolve Cisco IT's existing indoor wireless network infrastructure into a more available, stable and secure network. Cisco IT will increase the number of access points - from 3100 to more than 6000 - in more than 300 Cisco locations worldwide and deploy the latest intelligent and fully integrated Cisco wireless products. 

The next-generation WLAN is based on the Cisco Unified Wireless Network Solution, which combines centralized Cisco Wireless LAN Controllers with Lightweight Access Point Protocol (LWAPP)-enabled access points, and distributed, autonomous access points based on Cisco IOS Software.
