By utilizing enhanced techniques like MIMO communication and OFDM digital modulation extremely high data rates over large distances are possible for wireless communications. Predecessors like 802.11b/g standards are succesfully outnumbered and a strong competitor to other rising WLAN techniques e.g., UWB and Wimax is born. With the rapid migration of 802.11n into WLAN a new scenario arises where 802.11n networks and other nearby located 802.11b/g/n networks operate simultaneously. Forced to share the medium, interference between the networks is often inevitable, causing performance degredation in such way that the promised maximum data rates and communcation distances cannot be guaranteed. The objective of this thesis is to study these interference scenarios and gain a clear understanding of the consequences and effects of interference on the performance of the networks under consideration. In this regard real life measurements are performed and an analysis has been carried out. Our main focus will be on an 802.11n WLAN operating within the range of another 802.11b/g/n WLAN. We will observe the dramatic impact on the performance of the networks with respect to network throughput and packet loss rate. Consequently, the results of our study will address the eminent interference problem that the rapid growing WLANs are facing.
