The measurements are done at a number of diverse locations in order to study in detail the power and other characteristics of the man-made noise. We observe a significantly increased occurrence of noise compared to levels reported in the earlier literature. In some areas can even deteriorate the quality of service of deployed wireless networks. In this paper we present the measurement methodology, initial results, and show that the man-made noise is something that needs to be considered when planning future wireless systems.

Our focus is to understand if the increasing number of users and devices with inbuilt low-cost wireless transceivers has increased the noise levels considerably. We also study the stochastic properties of contemporary radio noise. In the literature, it is almost universally assumed that radio noise is well modeled by a white Gaussian stochastic process, and we study how often deviations from this baseline are found. Our measurement approach is able to capture frequency-and time-domain data with very high accuracy in diverse indoor and outdoor locations, providing a broad overview of the influence the environment has on noise and man-made interference. The results cast doubts on the widely used assumptions that consider man-made interference as an extra AWGN component over thermal noise floor. We also discuss the issue of modeling the measured radio noise and we explain the major research challenges for future work.

Our focus is to understand if the increasing number of users and devices with inbuilt transceivers has increased the noise levels considerably. In the literature it is almost universally assumed that the radio noise is a white Gaussian stochastic process and we are testing also how often deviations from this baseline are found. Our measurement approach is able to capture frequency and time domain data at very high accuracy. In this paper we report the first results from several different spatially separated measurement areas, enabling the study of noise levels at diverse indoor and outdoor locations. Our results show that the noise levels have indeed been increasing and we present a specific example on how these increased noise levels can affect today's telecommunications systems.
