Enterasys RoamAbout AP4102
Multi-Technology, Fully
Standards Compliant, Wireless LAN Access Point
The RoamAbout AP4102 is Enterasys' premier access
point and contains both “A” and “B/G” radios, Secure
Networks policy capabilities, the latest encryption
algorithms, and both internal and external antenna
support. Highly flexible, the AP4102 is able to
operate in standalone AP mode, point-to-point and
point-tomultipoint- mode, and as a thin AP with the
RBT-8X00 wireless switches.
The RoamAbout AP4102 offers enhanced security
features such as WEP, WPA (Wi-Fi Protected Access),
AES, WPA2 and SNMPv3, as well as manageability
features that include NetSight® Console, NetSight
Policy Manager and NetSight Inventory Manager
support, secure web management and secure Telnet
management, including the standard CLI interface. At
the same time, enhanced access control gives network
managers complete control over who connects to the
network.
The AP4102 includes two external antenna
connectors for use with both indoor and outdoor
antennas. The AP4102 also supports both
point-to-point and point-to-multipoint connections.
