Perusal of the details within, should provide the reader with an insight into general wireless indoor communications within the microwave spectrum, with respect to the problems laced, specific to noise corruption of the transmitted signal. Indoor communication systems are difficult to model, due to the largely random nature of the relevant environment, and the compounding factors that degrade system performance. These factors are many and varied, in accordance with the operational topologies of possible application area. However, there exists a common and increasing need to effectively model the communication links in question. Part of this strategy involves having an understanding of what levels of background noise exist within the operational area involved, and to what degree it is variable in accordance with application and link topologies. It is this requirement that provided the catalyst for my investigations. This study investigates the various noise sources evident on the two frequency bands allocated for wireless LAN applications, and considers the relative importance of the findings. As further perusal will reveal, the major disturbance likely to affect such technologies, are microwave ovens, both on a domestic and commercial scale. A lull statistical analysis is presented for the spectrum distribution and corresponding power levels for microwave ovens, with the results being utilised to present an examination of the possible influence that they may have upon the system, and the significance of such claims.
