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) Wireless QOS Enhanced Interference Avoidance Properties
