Today, applications and services that require accurate positioning, including traffic, navigation, and smartphones, are an integral part of our lives. In the future, however, more accurate and faster positioning will be required, mainly due to the presence of self-driving vehicles and drones.

At the same time, the demand for capacity and data rate required in wireless networks are growing rapidly, which cannot be accommodated by LTE network. These two challenges can be solved by the fifth-generation wireless systems, that are expected to be deployed beyond 2020. 5G needs to be a paradigm shift where technology innovations include the use of high frequencies, greater bandwidth, ultra-dense network, and increased number of antennas.

With the 5G solutions, the accuracy of the positioning can also be increased, achieving accuracy of up to 1 meter.

In my thesis, I tested with a simulation that the 5G system solutions, such as the use of ultra-dense networks and high frequency bands, under which circumstances and to what extent can improve the accuracy of the positioning.
