Toward Mobility Parameter Planning for 3GPP LTE in Rwanda

Abstract

Rwandan operators are switching 3G to 3.9 G/4G. However, there is some overlapping between 3G and Long Term Evolution (LTE). Further, mixed 2G, 3G and LTE network remain in place due to the high cost. So it is needed to measure the four basic radio resource management (RRM) in LTE system in order to ensure the desired quality of services. This survey presented a practical measurement results recorded from a live network of Rwanda using drive testing; with the aim to evaluate the performance of Rwandan mobile network and evaluate the effect of mobility parameter on network throughput. The analysis was based on the three key performance indicators in mobile parameter as Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ) and Received Signal Strength Indicator (RSSI). A measurement of channel quality represented by Signal to interference plus noise ratio (SINR) is used for measuring link adaptation. The collected data from the drive test will be the input for the study of the performance of the network and further the identified gap will be discussed in the future work.
