Abstract :
In this paper, the operation of an IEEE 802.11g wireless local area network (WLAN) system under the influence of narrowband interference is investigated. The IEEE 802.11g WLAN is defined to operate in the 2.4 GHz license free frequency band. Three different WLAN interface cards with different transceiver chipsets is were evaluated in laboratory environment. The performance was measured in a packet error rate as a function of signal to jamming ratio. The results show that narrow-band interference has a significant impact on the performance of an OFDM based system. It is possible to deteriorate the connection even with relatively low interfering signal power levels for some of the vendor cards. The interfered subchannel choice has an influence on the effectiveness of the jamming
