Tiivistelmä
This thesis work was commissioned by Nokia Oyj. The goal was to run tests for
different radio units to verify a feature called “Smart thermal management” works,
study it and provide analysis on how it impacts the static test models used in RF
performance testing.
The feature itself combines different methods to reduce radio unit temperature as
required. The target of this is to meet customer needs, improve the longevity of
the unit and cut down on maintenance costs, while still providing reliable
connection from the user’s point of view.
Five different radio units were successfully tested during this study. With the help
of the completed tests the testing process was optimized to provide more
accurate results and better monitoring. The impact on static test models used in
RF performance testing was addressed with a new procedure called
“Temperature chamber calibration”. New temperature configuration was also
created that can be further improved in the future.
For the reader, this thesis provides a good overview of what RF testing and the
testing process for new features can be like.
