How Cisco Upgraded Its Wireless Infrastructure

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.

  • Cisco
    Cisco designs and sells broad lines of products, provides services and delivers integrated solutions to develop and connect networks around the world, building the Internet. Over the last 30 plus years, they have been the world’s leader in connecting people, things and technologies - to each other and to the Internet - realizing their vision of changing the way the world works, lives, plays and learns. Today, Cisco have over 70,000 employees in over 400 offices worldwide who design, produce, sell, and deliver integrated products, services, and solutions. Over time, they have expanded to new markets that are a natural extension of their core networking business, as the network has become the platform for automating, orchestrating, integrating, and delivering an ever-increasing array of information technology (IT)–based products and services.

  • 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 customer can draw on Cisco IT's real-world experience in this area to help support similiar enterprise needs. 

  • CONNECTIVITY PROTOCOLS
  • 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.

  • USE CASES
  • Process Control & Optimization
    Process control and optimization (PCO) is the discipline of adjusting a process to maintain or optimize a specified set of parameters without violating process constraints. The PCO market is being driven by rising demand for energy-efficient production processes, safety and security concerns, and the development of IoT systems that can reliably predict process deviations. Fundamentally, there are three parameters that can be adjusted to affect optimal performance. - Equipment optimization: The first step is to verify that the existing equipment is being used to its fullest advantage by examining operating data to identify equipment bottlenecks. - Operating procedures: Operating procedures may vary widely from person-to-person or from shift-to-shift. Automation of the plant can help significantly. But automation will be of no help if the operators take control and run the plant in manual. - Control optimization: In a typical processing plant, such as a chemical plant or oil refinery, there are hundreds or even thousands of control loops. Each control loop is responsible for controlling one part of the process, such as maintaining a temperature, level, or flow. If the control loop is not properly designed and tuned, the process runs below its optimum. The process will be more expensive to operate, and equipment will wear out prematurely. For each control loop to run optimally, identification of sensor, valve, and tuning problems is important. It has been well documented that over 35% of control loops typically have problems. The process of continuously monitoring and optimizing the entire plant is sometimes called performance supervision.
