Introduction
WLAN networks are operating in nonlicencied band. As such they do not need frequency planning but also the interference level is not controlled. A bad communication environment could significantly to deteriorate the communication quality. Additionally to the interference imposed limitation the 802.11 family products do have interent drawbacs when applied to the real time traffic, like for example for voice communicaiton.
In this laboratorywork we measure how the interference impact to the delay and the troughput of an WLAN adhoc network. We measure the interference environment and see how selection of the communciation frequency impacts the system. Reagarding the protocol suitability for real time traffic we measure the troughput as a function of packet length. The measurements are compared to the theorethical values calculated in the preliminary exercises.
