  1. Chapter 11-WLAN Deployments and vertical Markets • Corporate data access and end-user mobility • Network extension to remote areas • Bridging—building-to-building connectivity • Wireless ISP (WISP)— last-mile data delivery • Small office/home office (SOHO) • Mobile office networking • Educational/classroom use • Industrial—warehousing and manufacturing • Healthcare—hospitals and offices • Municipal networks • Hotspots—public network access • Transportation networks • Law-enforcement networks • First-responder networks • Fixed mobile convergence • WLAN and health • WLAN vendors

  2. Exam Essentials • Know the different WLAN vertical markets. • Wireless networking can be used in many environments, with each vertical market having a different primary reason or focus for installing the wireless network. Know these environments and their main reasons for deploying 802.11 wireless networking. • Know fixed mobile convergence • With cellular networking and Wi-Fi networking so common, telephone vendors are beginning to provide phones that are capable of communicating over both networks and provide roaming between them. Know what FMC is and the reasons and benefits of deploying it.

  3. Corporate data access and end-user mobility • Cost of wiring jacks is expensive • Since data access is becoming critical to business • Wireless makes working where you are easier • However, wireless has drawbacks • Slower • Performance • throughput Pg 368

  4. Network Extension to Remote Area • Giving access where there is no cabling Pg 368

  5. Building to Building Connectivity • Bridging • Cost of laying cable is hi, wireless can be cheaper • Still manage your own network • Depends on locations and distances • Line of site and Fresnel Zone! Pg 368

  6. Wireless ISP • Often non 802.11 • In places where other techs aren’t available • DSL distance limits Pg 370

  7. SOHO • Easy to use, often plug and play systems • Support network services • Often contain wired and wireless functions Pg 370

  8. Mobile Office Networking • Temporary structures/classrooms • Provide bridging to a wired temp office/space Pg 371

  9. Educational/Classroom • Flexible layout • Not tied to walls • Often used to bridge between buildings Pg 371

  10. Industrial/Warehouse • Along with RFID • Inventory • Bar code scanners, etc Pg 372

  11. Healthcare/Hospitals • Need quick access to data • Meds, records, etc • Also in use with RFID • Location services • Ned to watch for interference Pg 372

  12. Municipal Networks • Cities and towns wanting to offer as a service • Many didn’t plan on complexity/cost • Not as common now, many failed attemtps Pg 373

  13. Hotspots-Public • Pay or free • As service to customers • Airports, bookstores, etc • Use Captive Portal to get sign on or payments • Insecure Pg 373

  14. Transportation Networks • More and more carriers are offering wireless service • Planes • Trains • Some vans/buses as well • Usually linked to satellite or cellular data networks Pg 374

  15. Law-Enforcement • Use WiFi in addition to existing public service networks • Some locales are integrating mesh networking • WiFi in municipal parking lots • Automatic upload/download of data when in range Pg 375

  16. First Responder • Vehicles carry technology to create a local WLAN • Support for devices • Backup to radios Pg 376

  17. Fixed Mobile Convergence • Switching between wired and wireless • Femto-cell/Pico-Cell • Cell Phones that switch to WiFi Pg 376

  18. Wireless and Health • Wireless and health studies are ongoing Pg 376

  19. Vendors • Lots in list • Each has different solutions Pg 377

  20. Exam Essentials • Know the different WLAN vertical markets. • Wireless networking can be used in many environments, with each vertical market having a different primary reason or focus for installing the wireless network. Know these environments and their main reasons for deploying 802.11 wireless networking. • Know fixed mobile convergence • With cellular networking and Wi-Fi networking so common, telephone vendors are beginning to provide phones that are capable of communicating over both networks and provide roaming between them. Know what FMC is and the reasons and benefits of deploying it.
