the next years, driven by the increasing demands of homeowners considering
energy monitoring, management, environmental controls and security.
<br><br>
Many of these new systems will be installed in existing homes and offices
and therefore using radio based systems for cost reduction. A drawback of
radio based systems in indoor environments are fading effects which lead to
a high variance of the received signal strength and thereby to a difficult
predictability of the encountered path loss of the various communication
links.
<br><br>
For that reason it is necessary to derive a statistical path loss model
which can be used to plan a reliable and cost effective radio network. This
paper presents the results of a measurement campaign, which was performed in
six buildings to deduce realistic radio channel models for a high variety of
indoor radio propagation scenarios in the short range devices (SRD) band at
868 MHz.
<br><br>
Furthermore, a potential concept to reduce the variance of the received
signal strength using a circular polarized (CP) patch antenna in combination
with a linear polarized antenna in an one-to-one communication link is
presented. |
