Performance evaluation of inter-band carrier aggregation for low-band and mid-band in 5G network

Abstract

The use of machinery to assist human activities and replace human tasks has become more advanced in the modern world. Therefore, broad and fast connectivity is needed to support it. 5G provides solutions for industries with diverse requirements, such as extensive coverage requirements and high network capacities. Inter-band Carrier Aggregation (CA) can accomplish this in the low-band and mid-band. The low-band provides broad coverage, and the mid-band offers large bandwidth. In this study, Inter-band Carrier Aggregation (CA) increases the data rate while maintaining broad coverage. The frequencies used are 700MHz with a 40MHz bandwidth and 3500MHz with a 100MHz bandwidth. This simulation uses The Mentum Planet Software version 7.3. This research observes The Karawang Industrial Area and uses an Outdoor-To-Outdoor (O2O) scenario with Line of Sight (LOS). The parameters observed were SS-RSRP, SS-SINR, and Data Rate. As a result, the SS-RSRP increased by 8.76%, the SS-SINR increased by 0.83%, and the peak data rate increased from 757.55â Mbps to 1192.26â Mbps.
