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

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 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.

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

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

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

Wireless ISP Often non In places where other techs aren’t available –DSL distance limits Pg 370

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

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

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

Industrial/Warehouse Along with RFID Inventory –Bar code scanners, etc Pg 372

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

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

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

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

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

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

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

Wireless and Health Wireless and health studies are ongoing Pg 376

Vendors Lots in list Each has different solutions Pg 377
