What is Celeno approach to QoS?
We believe that QoS is only one of the important aspects of a successful, robust wireless video streaming solution. After all, if the transmitted power does not reach its client destination, the QoS algorithms will be useless. Celeno OptimizAIR™ takes a holistic view and optimizes all aspects involved including PHY, MAC, Networking and Application layers in order to make sure range, throughput, and robustness targets are met. 802.11e standard and the Wireless Multimedia Extensions (WMM) define a contention-based QoS scheme with basic classification system that uses statistical prioritization of high priority streams such as video streams over low priority streams such as data streams. This method does not ensure strict prioritization of video over data and therefore cannot guarantee consistent and timely delivery of video traffic. Moreover, it does not ensure fairness between the video streams. The definitions for automatic rules for the QoS categories classification are missing from t
