Cisco WAP2000 Wireless-G Access Point with Power Over Ethernet Administration Guide 1

Introduction

Thank you for choosing the WAP2000 Wireless-G Access Point with Power Over

Ethernet.

The Wireless-G Access Point with Power Over Ethernet is ideal for small

businesses that want to expand their existing wired networks or create new

wireless networks for the workforce or guests. The access point features

RangeBooster technology that is compatible with standard 802.11g but with a

range up to two times further and throughput up to 35 percent faster. Unlike

ordinary wireless technologies that are hampered by wireless signals that reflect

off walls, ceilings, and other objects, RangeBooster uses these multiple signals

with two smart receivers at each end (router or access point and client adapter) to

boost range and throughput speeds. As a result, a RangeBooster solution reduces

or eliminates wireless signal dead spots in offices and other buildings so users

can connect to the network in more areas. The access point comes with two 3 dBi

antennas for increased power, also helping to extend the range of the access

point.

Advanced security features like Wi-Fi Protected Access™ (WPA2 Enterprise),

make this solution ideal for business. Integrated Quality of Service (QoS) features

provide consistent voice and video quality on both the wired and wireless

networks, enabling your workforce to communicate or view video content without

disruptions and delay.

The Wireless-G Access Point with Power Over Ethernet can be powered from its

included AC adapter or from a Power over Ethernet (PoE) Switch using Ethernet

cabling, enabling mounting in ceilings or high on walls where power outlets may

not be available.

Additional features like multiple BSSIDs, wireless roaming, and auto-channel

selection, give your business added flexibility to keep employees and guests

connected. The access point also features dual firmware images so it remains

functional if a firmware upgrade process is disrupted.

Planning Your Wireless Network

Before deploying your WAP2000 Wireless-G Access Point with Power Over

Ethernet, take some time to plan your wireless network.

This chapter includes the following topics:

•Network Topology, page 2

•Roaming, page 3

•Network Layout, page 3

•Example of a Simple Wireless Network, page 4

Network Topology

A wireless network is a group of computers, each equipped with one or more

wireless adapters. Computers in a wireless network must be configured to share

the same radio channel to talk to each other. Several computers equipped with

wireless cards or adapters can communicate with each other to form an ad-hoc

network without the use of an access point.

Cisco wireless adapters also provide access to a wired network when using an

access point or wireless router. An integrated wireless and wired network is

called an infrastructure network. Each wireless computer in an infrastructure

network can talk to any computer in a wired or wireless network via the access

point or wireless router.

An infrastructure configuration extends the accessibility of a wireless computer to

a wired network, and may double the effective wireless transmission range for

two wireless adapter computers.

Because an access point can forward data within a network, the effective

transmission range in an infrastructure network may be doubled (depending on

antenna characteristics).

Planning Your Wireless Network

Roaming

Cisco WAP2000 Wireless-G Access Point with Power Over Ethernet Administration Guide 3

Roaming

An infrastructure configuration also supports roaming capabilities for mobile

users. Roaming means that you can move your wireless computer within your

network and the access points will pick up the wireless computer’s signal,

providing that they both share the same wireless security and SSID.

Before you consider roaming, choose a feasible radio channel and optimum

access point position. Proper access point positioning combined with a clear

radio signal will greatly enhance performance.

NOTE Spanning Tree Protocol should be disabled on the switches connecting to the APs

to allow roaming to work without disruption.

Network Layout

The WAP2000 access point has been designed for use with 802.11g and 802.11b

products, such as the notebook adapters for your laptop computers, PCI adapters

for your desktop computers, and USB adapters for either a laptop or desktop.

These wireless products can also communicate with a 802.11g or 802.11b

wireless print server.

To link your wired network to your wireless network, connect the access point’s

Ethernet network port to any switch or router.

Example of a Simple Wireless Network

The following diagram shows a typical infrastructure wireless network setup.

This example shows a typical infrastructure wireless network setup. The wireless

access point connects to a switch that provides power to the access point. The

access point can connect multiple wireless devices to the network.

This network provides connectivity among wireless network devices and

computers that have a wired connection to the switch. The switch connects to a

router that connects to an ISP for Internet access.

Front Panel

The LEDs on the front panel of the access point display information about network

activity.

POWER—(Green) Lights up when the access point is powered on.

PoE—(Green) Lights up when the access point is powered through an Ethernet

cable.

WIRELESS—(Green) Lights up when the wireless module is active on the access

point. The LED flashes when the access point is actively sending or receiving data

from a wireless device.
