ABSTRACT
The migration of UMTS carrier frequencies to
the 2 GHz band has stimulated interest in radio
coverage in urban environments. This paper
examines the problem of poor signal quality
close to buildings. It uses simulation based on
approximate propagation models in a "generic"
urban environment to estimate the relationship
between size of coverage black spots and
distance from the serving BS. Consideration is
also given to the possibility of using channels
allocated to in-building picocells as a means of
mitigating against coverage black spots.
