2.4+5GHz PoE Access Point. This cost-effective IEEE 802.11n draft 2.0 PoE access point is designed to meet the needs of business of all sizes. It even supports IP telephony, ensuring high-levels of quality of service. The 3Com AirConnect 9550 dual-radio access point has both 2.4 GHz and 5 GHz 11n radios allowing it to support simultaneous 2.4 GHz 11b/g/n and 5 GHz 11a/n wireless connections, a feature typically found in only the more advanced enterprise-class products. One standard IEEE 802.3af PoE port provides flexible installation options in hard-to-wire locations by eliminating the need for an AC power plug at each AP. Any 3Com PoE Switch or other 802.3af-compliant PoE product supplies both power and data to the access points through Category 5 or 6 Ethernet cable. 3Com offers one of the most robust suites of standards-based security on the market today. The AirConnect 9550 supports the latest, most effective authentication techniques to thwart intruders and simplify network management. It delivers enterprise-class security to businesses of all sizes by protecting wireless data through the use of Wi-Fi Protected Access (WPA2) with 128-bit Advanced Encryption Standard (AES) encryption (the latest, toughest standards-based security); WEP encryption is also supported for legacy clients. To protect against unauthorized network access, the access point supports IEEE 802.1X authentication and authorization through backend RADIUS servers using EAP-TLS, PEAP and EAP-TTLS. MAC address access control and peer-to-peer client restrictions provide further security options. Other advanced features include support for multiple SSIDs for each group of wireless users, IEEE 802.1Q VLANs, and s  (less)

and other cycle-intensive tasks from the host CPU - resulting in optimal system and application response. The lack of electrical resistance makes fiber-cabled infrastructures particularly useful for reducing line interference or "noise", extending connection distances over 100 meters, or delivering the highest-quality voice and video transmissions. Intelligent management and server features help improve network performance, reduce administration time, and lower support costs.  (less)
