3Com®Wireless 7760 11a/b/g PoE Access Point

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

edium 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 upto 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

y both power and data to the access points through Category 5 or

suppl 6 Ethernet cable, giving you flexible installation options in hard-to-wire or -reach locations.
