Enterprise Wireless – What are the REAL Operational Issues???
… Is the wireless LAN ready?
High Utilization = Low Throughput
Issue #1 – Poor Performance
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
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?
Channel Coordination
• Easy to deploy
• Easy to manage
• Easy to expand• Enterprise WLAN ready
RESOLUTION: Single-Channel Deployment

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.

Foundry Key DifferentiatorsThe 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

• Designed for any deployment scenario, migration plan & budget• 802.11n Draft 2.0 dual band AP320 & single band AP310 • Upgradeable, cost-effective 802.11a/b/g AP311 & AP302
• Supports 802.3af PoE and new 802.3at PoE+• Investment protection for legacy switches and seamless
transition to new standards
• Closes the 802.11n rogue AP security gap• Detects, alerts & monitors 802.11n rogue APs
• Maintains performance leadership for highest scalability & ease of deployment• Advanced reservation-based QoS allows 64 users per radio with no
performance loss due to contention. • No more wasteful Pico-cells to manage high density networks
• Single-channel advantage eliminates complex RF planning & need for special adaptive radios. Greater coverage with fewer access points.
• Unpredictable channel access, latency, jitter
• AP gets proportional share of channel as one of the clients
No over-the-air QoS
• Predictable channel access, latency, jitter
• AP gets the right amount of channel access (50%)

Air Traffic Control Technology – 5x QoS Voice Calls per Access Point
• 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….. No deployment complexity!

Foundry’s channel spans preserve RF resources
Conventional WLAN channel plan consumes RF resources
Add capacity where you need it…Multi-channel Layering
All RF channels are consumed to provide a single channel of
capacity per region
