Abstract:This paper presents measurements of radio interference
using ”Ambient μNode” sensor nodes. By varying distances
and frequencies we get a measure of the interference
caused by transmissions on adjacent bands. Our observations
show that adjacent spectrum interference influences
the data delivery, considerably. Channels should be separated
in the spatial or in the frequency domains if interference
is to be avoided. In addition, the distance to simultaneous
transmitters and the number of simultaneous transmissions
are highly correlated with channel spacing. Therefore,
channel spacing can be adjusted according to spatial
distances so that multiple concurrent transmissions can be
performed without interference. We also give proposals for
further investigation on the usage of this correlation that
are relevant to the design of future multi-channel protocols.
