Wireless Local Area Networks (WLANs) extend the usage of wired LANs from specific places within a building to the many mobile users whether in the building or outside. The wireless data is not only used by authorized users but also might be intercepted and altered by other unauthorized users. Therefore, the power of the transmitter is kept as low as possible to make it difficult for the others to intercept the signal. In the absence of interception, adversaries might attempt to jam the signal so that the network cannot operate properly. The purpose of present study is to investigate the effects of noise jamming against a WLAN in a high-rise building. The building model was created by Rhino, a well known Windows-based computer drawing software. The jamming effects are simulated using Urbana. The LAN transmitter operates with an omni-directional antenna and 100 mW of power. The noise jammer has variable power levels of 10 W and 100 W. It uses a directional antenna. The signal-to jam-ratio (SJR) is computed for several floors in the building to determine if the jammer will disrupt the WLAN.
