5. Important Breakthroughs Network BeamFlex™ Minute Config™ Unmatched price/value

6. First-of-its-Kind Smart Wi-Fi  Patented BeamFlex™ beam-steering antenna  Directional elements add range, reject interference  Combined elements to provide extended coverage  Self-learning software selects best combo in real time  Maximizes performance  Placement/orientation indifferent  Completely compatible with all 802.11 devices  Proven in over 1 million AP installations  Already deployed by 200 service providers worldwide  Acclaimed for superior coverage, video-worthy performance N antenna elements 2 N -1 unique beam patterns Self Learning, Self Optimizing, Self Healing Wi-Fi Antenna System

7. How BeamFlex Works  BeamFlex antenna directs Wi-Fi signals to clients  Automatically rejects Interference Metal Wall  Steers signals around impenetrable obstacles  Automatically adapts to moves, adds and changes  BeamFlex antennas make “good neighbors” ZoneFlex AP Fewer APs reach farther, faster, for more users AUTOMATICALLY!

8. Network BeamFlex  Add capacity and coverage as needed  No new Ethernet cables to APs  Auto topology with BeamFlex path selection algorithm  Self-organizing/self healing  Auto RF: beam-steering, centralized channel and power coordination Hotel ZoneFlex Mesh Simplifies WLAN Deployment and Expansion  Secure encrypted backhauls  10 APs per wireless cluster  Three hop max in a tree-structured mesh  802.11g, n support

9. Effortless Configuration In 5 Minutes or Less

10. Simplified Robust Security  The Problem: Provisioning secure wireless access  Single pre-shared key is not secure (e.g. employee leaving requires changing key for all employees)  802.1x is an overkill and not affordable for SMBs  No IT resource to administer unique key per employee  The Solution: Auto administered dynamic PSK  Automatic provisioning of unique encryption key to each user/device  No manual client configuration  Highly secure: unique 63-byte pass-phrase per user  Easily deactivated when employee leaves  New key can be generated periodically  Configurable per WLAN

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

12. The ZoneDirector 1000  First centralized multimedia WLAN control platform  Built for simplicity and robustness  Network, RF, security and location management all-in-one  Internal authentication database, seamless AD & RADIUS integration  Customizable management dashboard  AP heat map  Controls up to 50 APs  Standards-based CAPWAP  Automatic redundancy

13. ZoneFlex 2942 11b/g Multimedia AP  Business class BeamFlex  High density of mobile users  Optimum performance with variety of client devices  Advanced multimedia business QoS  Per-user rate limiting enables tiered services  Precision per-user, per-traffic class queues  Automatic traffic classification and tagging  QoS policies configurable per WLAN (SSID)  20 concurrent VoIP calls, 50+ data clients  Supports Network BeamFlex meshing 12 antenna elements provide 4000+ unique antenna patterns Up to 7dBi gain, 18 dB interference rejection

14. Unprecedented Price/Value  Purpose-built for SMB and hot zones  Simple, IT-Lite  Complete feature set  Competitors simply re-package complex enterprise bundles  Entry level solution starts at under $2K  Channel friendly  More budget for value-added services  Hooks for application integration  Multimedia, eg: video conferencing, surveillance, ad insertion  Tiered access  Reduced integration time and resources
