DATA SHEET
OVERVIEW
The 3Com®Wireless 8760 Dual-Radio 11a/b/g PoE Access Point is a
Power over Ethernet (PoE) wireless solution for enterprises of all sizes.
This fully-featured dual-radio access point functions simultaneously
with an IEEE 802.11b/g and an IEEE 802.11a radio and provides ultra-
fast speeds of up to 108 Mbps. Advanced security features such as Wi-Fi
Protected Access (WPA/ WPA2), Wired Equivalent Privacy (WEP) and
Open System are included. This new access point also provides multiple
SSID support and VPN passthrough along with VLAN support.
KEY BENEFITS
ENABLING WIRELESS FREEDOM
Takeadvantageof the freedom of high-speed networking without wires
with the Wi-Fi CERTIFIED 3Com Wireless 8760 Dual-Radio 11a/b/g PoE
Access Point. Wireless LANs (WLANS) are an attractive solution for
cost-effectivelyand securely extending mobile access to wired network
resources or creating full-featured networks in small and medium
businesses, remote sites, or temporary locations. Each access point (AP)
supports up to 64 wireless users per radio for a total of 128 users, leaving
plenty of room for growth.
PROVIDES PoE DEPLOYMENT FLEXIBILITY
PoE support makes it easier than ever to overcome installation problems
byeliminating the need for an ACpower plug at each AP. The 3Com
Baseline Switch 2226-PWR Plus or the Switch 4400/4500/5500 PWR or
other IEEE 802.3af-compliant PoE products supplyboth power and data
to the access points through Category 5 or 6 Ethernet cable, providing
flexible installation options in hard-to-wire locations. For convenience
aPoE adapter is supplied with the unit.

KEY BENEFITS
(CONTINUED)
SECURES AND PROTECTS WIRELESS COMMUNICATIONS
This new access point delivers enterprise-class security to businesses
of all sizes. To shield wireless communications at the source, WPA and
WPA2 encryption provide the latest, toughest standards-based security;
WEP encryption is also supported. For additional protection, the
access point supports IEEE 802.1X and MAC address access control,
authentication and authorization through backend RADIUS servers.
PROVIDES FLEXIBLE SECURITY AND ACCESS CONTROL
Configure and store up to four SSIDs with different security profiles
for groups of users. IEEE 802.1Q-compliant VLAN support works with
the multiple SSID feature to control access to network resources and
segment user traffic.
SOLVES COMPLEX CONNECTIVITY PROBLEMS
The Wireless Distribution System bridging feature solves complex
wireless connectivity problems. The access point supports both point-
to-point and point-to-multipoint WDS links as well as repeater mode
for flexible network deployment.

INSTALLATION AND MANAGEMENT CONVENIENCE
WDS bridge and repeater Multiple APs can function as bridges supporting point-to-point or multi-
configuration point modes; repeater mode extends wireless coverage.
PoE support Expands installation options by eliminating the need for power adapters
and AC outlets for APs.
Access Point Discovery program Automatically discovers AP devices to simplify configuration and management
(PCs with Windows based operating systems only).
SNMP support Enables the AP to be centrally managed by popular standards-based
network management applications such as SNMP v1, v2c and v3.
Syslog support Enables the AP to be centrally monitored by sending data to the network
Syslog server.
Web browser-based administration Familiar browser interface lets you configure and manage APs from
anywhere on the network.
FEATURES AND BENEFITS (CONTINUED)
PoE Support
Choose from several power options to
match your installation needs. First, the
PoE access point can be powered with
the supplied PoE injector.
The access point can also be powered
using an 802.3af-compliant PoE switch.
The switch provides both data and power
through the Ethernet cable.
