LTE Implementation Model with Combination Carrier Aggregation Based on Area Demographics

Needs for rapid data services on telecommunications networks continues to increase. The amount of data traffic every year always increases while voice traffic tends to stagnate or even decrease. 4G LTE technology (Fourth Generation Long Term Evolution) as the latest telecommunications network technology from 3GPP (Third Generation Partnership Project) can provide better speed and capacity than the previous technology. This 4G LTE implementation answers the challenges of the growing need for data services. In the implementation process, there are two major challenges, namely the limited frequency bandwidth at 1800 MHz due to having to share with the existing2G DCS 1800 MHz system, and the varied demographic conditions in Indonesia. The model was built by combining carrier aggregation and 4x4 MIMO types for bandwidth variations of S MHz, 10 MHz, 15 MHz and 20 MHz with a combination of frequencies at 1800 MHz and 2100 MHz. By simulating the area in Jabodetabek, different bandwidth models will be produced in each area based on technical aspects (coverage and capacity) and economic aspects. The results showed that in the type of metro area, dense urban and urban areas that are by technoeconomic is a carrier aggregation broadband of 15 MHz. Then for the appropriate sub-urban area, which is S MHz. Whereas for rural areas not yet included in any bandwidth criteria, this makes consideration that the rural area is not suitable for carrier aggregation for 8 MHz, 10 MHz, 15 MHz and 20 MHz.
