 Directional, high-gain
smart antenna
 Continually picks the best
signal path to clients
 Adaptive beam forming
and steering

10. Introducing SmartMesh™
First Intelligent, Centralized WLAN Mesh Solution for 802.11n and 802.11g
 Eliminates Ethernet cable to every AP
 Uses RF signal routing to determine best
paths to client and between mesh nodes
 Only mesh system that avoids interference
 Uses high-gain, long-range smart antennas
to minimize hops, improve performance
 Deploys in half the time, half the cost
of conventional WLANs
 Simple, simple, simple to configure/manage
Half the Cost
Half the Time
3X the Performance

11. Dynamic PSK™
1. First time user connects
to Ethernet port ZoneFlex 2942
2. User specifies URL to
be automatically
configured for WLAN
access
3. Once authenticated,
ZoneDirector auto-
provisions the requisite
WLAN settings and a RADIUS/AD
unique, dynamic PSK in
user’s wireless settings ZoneDirector
4. Key is bound to both
user and device until Router
invalidated
5. User can now connect IDS
securely to the WLAN
Internet
