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 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.

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 802.11

• 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
