Abstract

The most widely used mobile technology today is 4G LTE. In the development of 4G LTE technology, there are still many problems related to network performance due to the increasing number of users and the poor quality of coverage areas. From previous studies, only checking the quality of the network without conducting further improvement analysis. For this reason, it is necessary to analyze network quality performance and conduct network repair analysis in the area. To find out the quality of the network, it is necessary to take data in the field, the method used is the Drive Test method. From the results of the drive test, it was found that 60.85% of the 411 samples were in the bad category, causing many areas to experience bad spots. In this area, bad spots occur due to interference between site PAD018ML_Ganting Tabing and Site PAD192ML_Kuala Niur, as well as the distance between Site PAD018ML_Ganting Tabing and User Equipment is quite far and there is no cell serving from the nearest site in the area. That way it results in some areas experiencing poor network quality. From the analysis of area repair is carried out re-azimuth to correct the poor quality of tissues.

Abstract

In the development of 4G LTE technology, network speed (Throughput) in several regions has increased or decreased. Network speed (Throughput) certainly cannot be separated from Modulation.  In modulation there are several kinds of modulation schemes, be it QPSK modulation, 16 QAM modulation, and 64 QAM modulation. The modulation scheme is instrumental in increasing throughput. Based on several previous studies, they only check the Throughput parameters without doing a more in-depth analysis of the modulation scheme which also plays a very important role in network speed (Throughput). For this reason, it is necessary to carry out an analysis related to the effect of modulation on the throughput value. To find out the effect of modulation on throughput, it is necessary to take data in the field, the method used is the Drive Test method. Based on the results of the Drive Test, QPSK modulation has a Throughput value of 5.247.4 Kbps, modulation of 16 QAM has a Throughput value of 27.293.9 Kbps and modulation of 64 QAM has a Throughput value of 65.275.1 Kbps. Based on the data in the field and in terms of calculations, the modulation that most affects the throughput value is the modulation of 64 QAM. Modulating 64 QAM having 64 symbols where each symbol consists of 6 bits will make the data rate at throughput higher. This also applies to the use of modulation of 16 QAM (16 symbols with 4 bits) and QPSK (4 symbols with 2 bits).
