Abstract
One of the most engaging challenges for mobile operators in fast developing cities such as Kigali city are switching 3G to 3.9G/4G and to deal with the fast increase of the amount of data traffic . 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. Moreover the current mobile infrastructure network is unable to handle such massive consumer demand at good quality of service. However, low cost network offloading technique such as relay nodes need to be adopted by operators. The aim of this paper is twofold. First, to collect current network radio coverage data using network drive testing method. Network drive testing data collection 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. Second, study and enhance user QoS based coverage performance by focusing on relay nodes network offloading technique. The work should help to optimize end to end delivery quality for operators in fast developing cities.
