Implementation of the Inter-Band Carrier Aggregation Method to Solve Congestion Network Conditions in Urban Areas

The use of the internet today is inseparable from daily activities, such as communicating with other people, seeking the latest information, working, and others. Because of this, users expect that there will be an increase in the quality of the data network. However, network congestion problems arise due to current technological advancements and rising users. The inter-band carrier aggregation approach is used in this study to arrange for more frequency to alleviate network congestion. This method combines a frequency of 2.1 GHz and a frequency of 1.8 GHz as additional frequencies for LTE Advanced in North Jakarta with Key Performance Indicator (KPI) as the parameter focused on in this research. In order to cover the whole region adequately, this research found that 123 locations of sites were required through the use of a 0.474 km radius, with an average RSRP value of -69.42 dBm and an average SINR of 2.61 dB. The network quality obtained by the user is excellent, with 30,926.13 kbps average throughput and service with QPSK 1/2 modulation.
