z
System redundancy
Extricom enables full redundancy by connecting two switches in parallel to different APs over
the same area. The switchover parameters are user-configurable, and the Active to Standby
switchover is seamless to the user.
z
SNMP traps
The Extricom system supports SNMP traps, enabling the user to determine the status of the
system, including the status of APs and Redundancy statuses.
z
Rogue AP Detection
The Extricom system supports Rogue AP detection and reporting without the need for
additional hardware. By using one radio in each of the multi-radio APs, the Extricom Rogue AP
solution delivers the benefits of a dedicated security sensor network, without the costs of such a
physical overlay.
z
Multiple RADIUS & RADIUS Redundancy
The Extricom system supports multiple RADIUS servers, enabling the user to set redundancy
between these RADIUS servers.
z
Network Time Protocol (NTP)
The Extricom system supports synchronization of the system clock over the network, thereby
ensuring accurate local time keeping with reference to radio and atomic clocks located on the
Intranet and/or Internet.
z Fast Handoff (Opportunistic Key Caching)
The Extricom system speeds up the handoff of 802.11i WLAN stations between Extricom
switches by use of Extricom’s inter switch protocol. This technique enables the client to avoid
repetitive 802.1x authentications, thereby enabling faster transition between Access Points
connected to different switches with minimal session interruption.
Summary
The Extricom WLAN eliminates the cost and complexity of cell planning and site surveys for
interference analysis. The Multi-Layered blankets provide high-capacity, zero latency (seamless)
mobility, high level of security and ease of deployment wireless network.
