Chapter 4: WLAN Performance and Maintenance
As 802.11 wireless LANs mature, replacing less-convenient access methods and supporting mission-critical business applications, companies are beginning to demand dependable, robust wireless services. The best-effort performance so common in trial WLANs is simply unacceptable in most production networks. Try-it-and-see debugging cannot scale to support a large workforce that requires timely problem resolution. Companies that go wireless must be able to comprehensively monitor network activity, proactively identify trouble spots, quickly isolate failures, and plan ahead for the capacity required to sustain growth.
This chapter, the fourth and final segment of our All-in-One Guide to Wireless LANs, offers managing, monitoring and troubleshooting hints that can help you gain IT control over your company's wireless devices and users. From strategies for automated access point management to techniques for configuring wireless client software and policy, learn how to centrally administer a large distributed WLAN. Get a handle on the wireless performance characteristics that determine end-user experience and quality of service, and how to predict and measure them. And read practical tips that can help you troubleshoot failed 802.11 connections and radio interference issues.
