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 access point also provides multiple SSID
support and VPN passthrough along with VLAN support.
KEY BENEFITS
ENABLING WIRELESS FREEDOM
Take advantage of 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-effectively and 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 FLE IBILITY
PoE support makes it easier than ever to overcome installation problems
by eliminating the need for an AC power plug at each AP. The 3Com
Baseline Switch 2426-PWR Plus or the Switch 4400/4500/5500 PWR or
other IEEE 802.3af-compliant PoE products supply both 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
a PoE 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 FLE IBLE 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 COMPLE 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.
OFFERS INVESTMENT PROTECTION
No reason to replace APs as the network grows. Unique 3Com stand-
alone-to-managed conversion method allows the 3Com 8760 AP to be
used in stand-alone mode, or easily converted to be managed by the
3Com Gigabit Unified Wireless PoE Switch and 3Com WX-series
wireless controllers and switch.
DELIVERS ENTERPRISE-CLASS FEATURES
3Com delivers superior business value by offering enterprise-class
solutions without the complexity. 3Com also backs each product with
global sales, service and support along with technology, financial and
operational strength.
FLE IBLE HIGH-SPEED CONNECTIVITY
Dual-radio support Supports and offers 802.11a and 802.11b/g radios.
High-speed access 802.11a and 802.11b/g standard supports speeds up to 108 Mbps.
Wi-Fi a/b/g CERTIFIED Helps ensure interoperability with Wi-Fi CERTIFIED products from other
vendors.
ROBUST SECURITY FEATURES
Encryption: WPA/WPA2, AES, TKIP Toughest industry-standard algorithms help keep wireless transmissions
and WEP private.
Multiple security profiles Store up to eight different security settings; up to four security profiles
per radio.
Multiple SSID support with SSIDs can be bridged together or isolated.
SSID isolation
Access control Screens device MAC addresses to ensure that only trusted clients gain
access to the WLA .
802.1Q VLA support Groups users according to data or traffic requirements to segment traffic
flow based on business priorities.
RADIUS server MAC-based and Centralizes wireless security through existing network RADIUS servers.
802.1X AAA support

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).
S MP support Enables the AP to be centrally managed by popular standards-based
network management applications such as S MP 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.
Investment protection Use the AP as a stand alone unit, convert to managed functionality for
use with the 3Com Unified Wireless Switch, and then when needed,
convert to support 3Com WX-series wireless controllers and switch.
