    Abstract

    This paper presents measurements of radio interference using ��?Ambient Node��? sensor nodes. We varied distances and frequencies giving us a measure of the amount of interference caused by transmissions in adjacent bands. Our observations show that adjacent spectrum interference is an important influence to performance. Channels should be separated in the spatial or the frequency domains if interference is to be avoided. We also observed that distance to simultaneous transmitters and number of simultaneous transmissions are highly correlated with channel spacing. Hence, channel spacing can be adjusted according to the spatial distances so that multiple concurrent transmissions can be performed without interfering each other. We also give proposals to be further investigated about the usage of this correlation that is relevant to the design of future multi-channel protocols.
