Comsis dramatically improves the QoS of WiFi networks

July 28, 2011 - Comsis has just announced the completion of a new medium access method which dramatically improves the Quality of Service (QoS) of WiFi networks. This achievement was made possible by implementing an innovative MAC procedure in an IEEE802.11n-compliant access point. The complete design is hosted in a 3x3 MimoKit prototyping platform.

This medium access protocol is based on a joint development made by France Telecom and Comsis. This patented concept offers a better use of the bandwidth by dramatically reducing the number of collisions. It also highly reduces the variance of the delays required to access the communication medium, namely access time-jitter. In fact, the potential high variance in time-jitter represents the main issue in current WiFi circuits, which hinders the QoS for video streaming in particular. No existing standard WiFi solution has implemented such a MAC feature before.

Another important characteristic of this unique feature is that it is fully interoperable with the existing WiFi requirements. Although the best performance improvement is observed when all the network participants are equipped with this new MAC feature, a significant benefit already exists when only one such QoS-enhanced host is present.
