NetGlide Product Family Overview

1. NetGlide Product Family Overview

2. WLAN’s purchased by more and more companies to gain advantage over competitors, and by institutions (schools, hospitals) wanting to offer the best service. Explosive WLAN market growth: +28% year over year! (Dell’Oro group) Gartner: by the end of 2010, 1.2 billion people will carry handsets capable of mobile commerce and other advanced applications WLAN ideal access technology to support this mobility revolution, but earlier generation WLAN’s were not reliable enough. Allied Telesis- Netronics’s 4th generation wireless technology is built to support the mobility revolution. WLAN Quickly Becoming Core Access Network

When the organization needs… …Netronics delivers robust, wireless convergence that future-proofs the network and the business. • Real-Time Mobility • Reliable, steady and predictable throughput • Wireless that survives challenging physical environments • Multiple applications without trade-offs • A less complex solution, so IT focuses on IT, not wireless • 802.11n Results, Not just Hype and Promises

6. Technical background

7. Bandwidth Limitation Of Cell Based System Co-Channel Interference Roaming Edge Users • Always present • Client transmit power can’t be controlled • Client makes decision when to roam • Client might stick to “relatively” good AP reducing the performance of whole system • Roaming is done on lowest data rate • Creates interference • Ping-pong effect

8. Bandwidth Limitation Of Cell Based System • Radio channels are a scarce resource – use them wisely • Make each channel’s bandwidth available everywhere

9. Interference-Free™ Architecture • The channel blanket is formed from the aggregate coverage of all the APs • APs operate on the same channel(s) to create the channel blanket • The Switch completely controls the APs, preventing co-channel interference • The AP is only a radio/antenna; no software, no configuration; no IP address, no processing • The Client associates with the switch, not the AP; the APs are simply conduits between the client and the switch

10. Uplink in the Channel Blanket (1) (2) • Uplink path diversity • Multiple APs “hear” the client • Switch receives multiple copies of the same transmission, and selects the best one – making the uplink resilient to disruption on any one individual link • Seamless zero-latency mobility • As the client moves, different APs receive the uplink transmission - this is transparent to the client and no handoff event ever occurs • Elimination of client balancing problem that exists in cell-based WLAN

11. Netronics Wireless LAN • Total Mobility • Robust In Any Environment • Multi-Service Convergence • True Dual-Band 802.11n • Slashes the Complexity of Wireless and Networking

12. A Different Picture for Radically Different Results NetGlide • Channel Blanket • No Cell Planning Complexity • Robust Connection • Zero-Latency Mobility • Client Consistency 1 6 11 • Layer Any Mix of Channels, Modes and Band, from the Same Set of APs • Stacked Capacity • Built-In QoS • Dedicated Security “Simply a Better Way to Wireless” Cell / Virtual Cell Based 1 11 6 11 6 • Dramatic reduction in networking complexity 6 1 1

13. The NetGlide Experience Guaranteed Performance Move from “Best-Efforts” WLAN to Guaranteed Performance metrics Surprising Simplicity Take away the complexity of RF Total Mobility Voice demands true mobility – without it, convergence cannot succeed Voice, Data, & Video Without Trade-Offs One infrastructure investment, many uses, serving different users with predictable quality of service

14. 802.11n 2.4 GHz Scenario Today’s 3 non-overlapping channels collapse down to 1 x 40MHz and 1 x 20MHz channel “Full-performance” ‘n’ (i.e. the 300Mbps promise) requires a 40MHz-wide channel, with only ‘n’ clients Mixing ‘g’ clients with ‘n’ on the same channel reduces throughput by 4X! 20MHz wide channels provide half the data rate as 40MHz channels 2402 2407 2412 2417 2422 2427 2432 2437 2442 2447 2452 2457 2462 2467 2472 MHz Today Ch 1 Ch 6 Ch 11 802.11n/g 40MHz width 20MHz width

15. Advantage Netronics in 2.4 GHz Band • Netronics is the only technology capable of supporting full-performance 802.11n clients and permanent co-existence with full-performance 802.11b/g clients, all in the same AP deployment. Blanket 1: 40MHz “pure n” blanket Business as Usual: Enterprise-wide 802.11n + g/b WLAN n Blanket 2: 20MHz legacy b/g blanket b/g ? ? Mission Impossible: Not enough channels for cell planning • Cell-planning is not viable – insufficient channels for channel planning. Cell 1: 40MHz n/g cell ? ? n/g ? Cell 2: 20MHz n/g cell n/g ?

16. Netronics 802.11n The Channel Blanket™ Comes of Age Any combination of channels, bands, modes, & security Data 2.4GHz ‘n’ Voice 2.4GHz ‘b/g’ Multimedia 5GHz ’n’ Locationing 5GHz ‘a’ or Rogue Monitor Multiple WLANs in One means the onlydisruption-free, gradual introductionof full-performance‘N’ in the enterprise • Full-performance for both ‘n’ and ‘g/b’ devices in 2.4GHz • Full-performance for both ‘n’ and ‘a’ devices in 5GHz • Choice of Bands - no forced transition to and wireless redesign for 5GHz • 802.3af PoE powers full-rate multi-radio n/a/b/g Access Points • The benefits of MIMO, without the side-effects

17. Throughput Again and again, customers report how migration to NetGlide’s channel blanket solved their WLAN throughput problems.

18. The Channel Blanket = High Throughput • Higher density of AP’s than microcell • Users are closer to AP’s. Get better signal. Faster transmit/receive. • No ‘edge’ users • Uplink Diversity • No co-channel interference (the big enemy of microcell architecture is eliminated) • Can segregate 802.11n users from a/b/g users: 70% throughput increase!! • True Reuse

19. Robust Security • 802.11i hardware-based encryption for WPA2-TKIP/AES (CCMP) • Authentication: RADIUS (802.11x), Captive Portal, WPA pre-shared key (PSK), WPA2 EAP, TLS, LEAP, PEAP, MD5, MAC • Security policy: MAC address-based ACL, per ESSID/BSSID, built-in IDS, captive portal walled-garden, per-user dynamic VLAN assignment • Rogue AP detection with dual-band scanning

30. The Challenge • Tablet PCs, iPhones, 50 wireless projectors, and an iPod Touch for every student to leverage podcasts and vodcasts as part of their day-to-day instruction. • Throughput, mobility, reliability must-haves

31. Checked Out The Competition First • “I was beginning to think that wireless LANs might not be a feasible solution, because co-channel interference can severely reduce basic network performance during high usage periods…

32. Then Discovered Netronics …Netronics seemed almost too good to be true. I hadn’t heard of Channel Blanket technology, and couldn’t imagine wireless without dead spots or limitations caused by interference. But we piloted the Netronics solution onsite, saw that the performance claims were real, and went forward immediately with it.” Abdul Chohan, Essa IT Manager
