1. High Performance, Easy to Deploy Wireless

2. Agenda Foundry Key Differentiators Business Value Product Overview Questions

3. Poor Performance Slow Roaming DIFFICULT END-USERS Enterprise Wireless – What are the REAL Operational Issues??? … Is the wireless LAN ready?

4. High Utilization = Low Throughput Issue #1 – Poor Performance

5. High Utilization = Low Throughput RESOLUTION: Over-the-Air QoS & Contention Free Access High Utilization & High Throughput High performance High scalability High density Enterprise WLAN ready

6. Issue #2 – Deployment Limited Non-Overlapping Channels Channel Interference Add 3-Dimensions (Multiple Floors) to this and the Problem Magnifies. Automatic Radio Management or Pico-Cells for Performance and Density?

7. Channel Coordination Easy to deploy Easy to manage Easy to expand Enterprise WLAN ready RESOLUTION:Single-Channel Deployment 1 11 1

8. Issue #3 – Slow Roaming or No Roaming Clients require 200 ms to 5 seconds to roam Microsoft adds a level of complexity to this issue. Proprietary Solutions and Protocols help, but do not completely resolve the issue.

9. 200ms – 5 sec between APs Traditional APs < 3 msec between APs BSSID = ZZ 00:00 BSSID = XXBSSID = YY 01:00 Channel 1 Virtual Cell Architecture Single BSSID Channel 1 Channel 6 RESOLUTION: Seamless Roaming, Single BSSID – Virtual Cell No roaming packet loss No roaming delay No roaming latency Enterprise WLAN ready

10. Foundry Key Differentiators The VALUE… With all other Wireless features and functions the same… Foundry Offers: Over the Air QoS and Contention Free Access Increases Density of End-Stations per AP 75 to 150 Users per AP 20 to 30 VoIP over WiFi Users per AP Single Channel Deployment Minimizes Pre & Post Site Survey Requirements Makes Adding AP’s Easy Eliminates Redeployment Issues Single BSSID – Virtual Cell Architecture Removes the End-Station negotiation with the AP Makes the WiFi Network similar to the Cellular Network

19. Traditional WLAN To minimize interference power levels are lower so cell size is smaller– requires more Access Points, cable drops, and labor Recurring site surveys Adds/moves/ changes require channel reassignment Foundry WLAN Single channel eliminates interference so full power can be used, larger areas covered so fewer devices required Access Points can be added to increase capacity as needed without a channel planning survey To survey or not to survey …..
