INTRODUCING THE
OFFICECONNECT WIRELESS
ACCESS POINT
This chapter provides an overview of the features and capabilities of the
OfficeConnect® Wireless 108 Mbps 11g PoE Access Point. It also
identifies the contents of the Access Point kit and helps you get to know
the physical features of the device.
Overview 3Com wireless systems let you simply and confidently extend network
information and applications to difficult-to-wire locations and to your
mobile workforce, making your business more productive, competitive
and successful. The 3Com OfficeConnect Wireless 108 Mbps 11g PoE
Access Point is the affordable choice for extending your network to
places where wires cannot go.
A single Access Point can make the Internet, e-mail, and network
resources such as printers available to dozens of wireless station users.
And because 3Com OfficeConnect Wireless 108 Mbps 11g PoE Access
Point is Wi-Fi certified, you can be sure it will work reliably with certified
equipment from other manufacturers.
6 CHAPTER 1: INTRODUCING THE OFFICECONNECT WIRELESS ACCESS POINT
Figure 1 Network Architecture with OfficeConnect Wireless Access Point
Features and
Capabilities
The Access Point integrates standards-based features that provide for
seamless integration into your existing network and simplify
configuration and management. It also includes advanced security
features that help you control access to the wireless network and protect
data that is transmitted between wireless devices.

Features and Capabilities 7
PoE Support
PoE support makes it easier to overcome installation problems with
difficult-to-wire or hard-to-reach locations. The same Category 5 cable
that connects the Access Point to the wired network also provides its
power, so AC power outlet locations and extra cabling are no longer
issues. You can source power from an 802.3af-compliant power sourcing
equipment (PSE) or use the supplied power adapter to power the Access
Point.
You can use the following 3Com PoE products to supply power to
OfficeConnect Wireless 108 Mbps 11g PoE Access Point:

Power over Ethernet
(PoE)
Solves hard-to-wire location problems and reduces
cabling on the network. See “PoE Support”
.
User support Each Access Point can support up to 64 simultaneous
users (wireless stations), allowing plenty of room for
growth
WDS support Supports Wireless Distribution System (WDS) for
compatible wireless devices, allowing the Access Point to
act either as a wireless bridge or client/repeater. Both
point-to-point (PTP) and point-to-multipoint (PTMP)
bridge modes are supported. See “WDS Support”.
Simple configuration Provides an intuitive Web interface and default settings
that are suitable for most environments
DHCP client support Automatically obtains an IP address on a network that
has a DHCP server, simplifying configuration and
management
Upgradeable firmware Device firmware in a flash memory can be upgraded
easily from the Web interface
Table 1 Wireless and Networking Features
Feature Description
8 CHAPTER 1: INTRODUCING THE OFFICECONNECT WIRELESS ACCESS POINT
WDS Support
Wireless Distribution System (WDS) allows you to build a completely
wireless infrastructure using access points, instead of wires, to
interconnect multiple networks. WDS also helps you create large wireless
networks by linking several wireless access points with WDS links. WDS is
normally used in large, open areas where pulling wires is cost prohibitive,
restricted, or physically impossible.
You can use the Access Point to build a WDS on the network. It can
function either as a wireless bridge or wireless client/repeater.
For WDS to work, all participating access points in the distribution system
must support WDS. If you are using access points other than the
OfficeConnect Wireless 108 Mbps 11g PoE Access Point to build a WDS,
check the documentation for these access points and verify that they
support WDS.
Wireless Bridge
In a wireless bridge configuration, access points are configured to
interconnect or “bridge” two or more wired local networks at the link
layer. When wired local networks are bridged, devices on each network
can access resources on the other network.
The Access Point supports two wireless bridge modes:
Point-to-Point (PTP)
Point-to-Multipoint (PTMP)
In PTP mode, only two access points are configured to bridge two wired
networks. To configure the OfficeConnect Wireless Access Point to bridge
with a compatible access point, you need to specify the MAC address of
each device on the other to establish a PTP bridge. Figure 2
illustrates
how two access points in PTP mode connect two wired networks.
Features and Capabilities 9
Figure 2 Point-to-Point WDS
PTMP mode, as shown in Figure 3, interconnects three or more wired
networks using multiple access points that function as wireless bridges. In
a PTMP configuration, one access point is configured as the master AP
and set to PTMP mode. The other access points, or the “slaves”, are set
to PTP mode. Master and slave APs in a WDS identify each other by their
MAC addresses.
If you configure the OfficeConnect Wireless Access Point as the master
AP and define the list of access points that are allowed to bridge with the
master AP, you can the set up WDS links with up to eight slave APs. If you
do not define a list of allowed access points, up to 14 slave APs can
bridge with the master AP.
All traffic between slave APs goes through the master AP. The master AP
can bridge with all slave APs, but the slave APs cannot bridge with each
other.

Secure WDS Communication
The Access Point secures WDS links using either WEP or WPA-PSK
encryption. If you use WEP, all APs in the system must use the same WEP
key. If you use WPA-PSK, you must create the same security profile (with
the same SSID) on both master and slaves, and configure both master
and slaves to use WPA-PSK.
Wireless Client/Repeater
The Access Point can also function either as a client or repeater. You can
use the Access Point as a repeater to extend the range of your wireless
network. See Figure 3
for an illustration of how the Access Point works as
a repeater.
