* Planned Feature



Purpose: To observe maximum throughput achieved during continuous 100KB file transfers to and from a wired computer to a MU.

Environment: No RF Interference, some multipath, private wired network

Results: The table below lists the average throughput of continuous (for 5 minutes) Gets (wired -> wireless) and Puts (wireless -> wired). The average of the Gets and Puts is taken as the effective throughput.

WLAN systems are data centric supporting low data rate applications (e.g., scan-send-beep, etc.)

With multimedia applications (voice, video, audio) proliferating, proactively managing the scarce wireless bandwidth is critical

The Intelligent Access Point (IAP) includes: Packet Engine (PE)- Classifies data streams based on media

type. Current support provides voice, video and data classes

Quality of Service (QoS) Manager- Prioritizes and Optimally

schedules classified data streams based on policies set by system administrators according to their organizations needs

The technology can be extended in the future to support additional security management (firewall protection, content filtering), and accounting/billing (for different services)

Adaptive Interference Processing

Adaptable Rate Switching Algorithm

Optimizes 802.11b Throughput in Bluetooth Environment.

Uses Statistical Analysis in the AP to Predict Bluetooth Traffic/Interference

Provides Dramatic Throughput Improvement

I am Bluetooth! Hear Me SHOUT…



Downstream 802.11 Traffic is Most Susceptible Conventional rate scaling algorithms might scale back all the way

to 1 Mbps and stay there (scaling back results in increased collisions)

Need for a mechanism that predicts when Bluetooth is around and “lock” the transmission rate at the best possible point
