3Com® Wireless 7760 11a/b/g PoE Access Point
DATA SHEET
Secure and reliable,
108 Mbps wireless
connectivity with PoE,
for small to medium
businesses. This
innovative access point
provides advanced
security features
including WPA2, AES,
support for multiple
SSIDs, VLANs and Rogue
AP detection making it
a true enterprise-class
solution.
OVERVIEW
The 3Com® Wireless 7760 11a/b/g PoE Access Point is a cost-effective
dual band, Power over Ethernet (PoE) wireless solution for small and
medium enterprises. Configurable, this access point can operate at IEEE
802.11a or can be used as an IEEE 802.11b/g access point.
With the latest advanced security features such as Wi-Fi Protected Access
(WPA/ WPA2), Wired Equivalent Privacy (WEP) and Open system this
access point (AP) provides ultra-fast speeds of up to 108 Mbps in turbo
mode and offers superior long-range connectivity with eXtended range
(XR) technology. This new access point also provides multiple SSID
support and VPN passthrough along with VLAN support.
KEY BENEFITS
ENABLE WIRELESS FREEDOM
Take advantage of the freedom of high-speed networking without wires
with this Wi-Fi CERTIFIED 3Com Wireless 7760 11a/b/g PoE Access
Point. WLANs are an attractive solution for cost-effectively and securely
extending mobile access to wired network resources and for creating
full-featured networks in small to medium businesses, remote sites or at
temporary locations. Each access point supports up to 64 wireless users,
allowing plenty of room for growth.
PROVIDE POE DEPLOYMENT FLEXIBILITY
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 2226-PWR Plus or other 802.3af-compliant PoE products
supply both power and data to the access points through Category 5 or
6 Ethernet cable, giving you flexible installation options in hard-to-wire
or -reach locations.
3COM ® WIRELESS 7760 11A/B/G POE ACCESS POINT
KEY BENEFITS
(CONTINUED)
SECURE AND PROTECT WIRELESS COMMUNICATIONS
3Com delivers enterprise-class security features to small and medium
businesses. To shield wireless communications at the source, WPA2
with TKIP/AES encryption provides the latest, toughest standards-based
security—WEP encryption supports legacy 802.11b wireless clients.
For additional protection, this access point supports IEEE 802.1X and
MAC address access control, authentication, and authorization through
backend RADIUS servers.
PROVIDE FLEXIBLE SECURITY AND ACCESS CONTROL
You can 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.
SOLVE 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
and client bridge modes for flexible network deployment.
DELIVER 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.
