Tiivistelmä (eng):The pursuit of more bandwidth and more efficient spectrum usage has led to consider the use of Long Term Evolution (LTE) technology in unlicensed spectrum, a concept particularly useful for indoor deployments.
However, LTE must be modified in order to guarantee a fair coexistence with other systems, particularly WiFi.

There exist several coexistence methods, such as listen-before-talk (LBT), advanced channel selection, duty cycle, and variations of them.
Research into unlicensed spectrum has focused into LTE Licensed Assisted Access (LAA) and LTE-Unlicensed (LTE-U), expected to be specified in 2016.

The contribution of this thesis is complementary to the current work, and is focused on coexistence from the perspective of network planning and radio access optimization.
This is accomplished with a framework that yields optimized network topologies that maximize the benefits from the LTE deployment, fulfill coverage criteria, and minimize interference.
The efficacy of the statistically optimized network topologies has also been validated by means of system level simulations.
