Analysis of IEEE 802.11E Standard in Terms of Real Time Application Requirements

The new IEEE 802.11 standard version - 802.11e, was developed in order to introduce mechanisms enabling handling of real time applications in the network. The first part of this paper contains short descriptions of the original and modified method of controlling access to the transmission channel. Using the further presented results of simulation tests it is possible to determine system operation intervals in which the network guarantees the required quality of service to traffic streams of a given class. The summary contains most important conclusions from the comparison of working principles of both mechanisms as well as the executed experiments.
