Physical Cell Identity

With the growth of the customers and the expansion of the 4G LTE network in the area of Padang City, a PCI (Physical cell identity) modulo interference spot has been detected. PCI modulo interference occurs when an area is covered by two or more cells, which have a strong signal, and these cells have the same PCI modulo value. Based on the measurement results by the driving test method, the network conditions were not optimal because the SINR percentage (Signal to Interference Noise Ratio) in the good category was still low, at 9.47%, and the download throughput in the good category was 18.94%. This indicated that the interference in the area was quite high. Thus, it was necessary to do optimization action. The optimization action was taken by rotating the PCI on the site by considering the modulo value of each site so that the PCI with the same modulo did not merely lead to one location. Besides, action was taken to change the azimuth direction of cells that were too dominant. Based on the optimization process that has been carried out and the driving test activities that have been carried out again, the performance in the existing conditions has increased. The SINR percentage in the good category increased by 10%, so it became 19.47%, and the download throughput in the good category increased by 44.74% and became 63.68%.

The Difference

The development of technology is connected with customer needs for the speed and stability of LTE network access. Ensuring the quality of the LTE network can be done by measuring using the drive test method in the service area. The test drive must be equipped with software such as Nemo Handy and G-Net Track Pro. Nemo Handy is a professional drive test software that is widely used by providers, while G-Net Track Pro is a drive test software that was previously applied in the learning process at the campus. So that the measurement results using Nemo Handy and G-Net Track Pro for RSRP, RSRQ and SINR parameters need to be compared to performance. From the comparison of RSRP between measurements with theoretical stated Nemo Handy measurement results are closer than G-Net Track Pro. For example, the difference between RSRP in the PURADEMAK eNodeB for Nemo Handy was 5.96 dBm and the G-Net Track Pro was 9.4 dBm. This is due to the weakness of the G-Net Track Pro device that does not have the PCI locking feature as in Nemo Handy so that at some point the measurement cannot be compared.

Handover Performance

One of the advantages of mobile communication is Handover. The research data can be used to identify network problems such as weak signal level (RxLev), poor signal quality (Rx Qual), etc. which cause the handover quality at that site in certain areas to be affected as well. The purpose of this research is to determine the quality of a signal that will affect the performance of the handover frequency both intra-frequency handover and inter-frequency handover on the 4G LTE network by paying attention to the KPI Site of the relevant vendor, in this case PT.GCI Indonesia. The method used to determine the signal quality and network performance in an area, namely measuring and retrieving data with a drive test. One of the data collection techniques on the 4G network is to use the SSV (Single Site Verification) method on the drive test so that the signal quality and handover analysis are known both intra handover and inter handover using the GENEX Probe software. From the results of this study, it was found that the signal quality and handover quality of the 4G LTE network met the standardization given by the KPI, for the requirements for the success of the handover, which was 100% with the signal quality of the RSRP and SINR parameters resulting in a percentage of 73% and 91.21% according to the standards desired by the operator. and vendors using the Single Site Verification (SSV) drive test method.

Coverage Planning

Untuk meningkatkan kinerja jaringan 4G yang merupakan jaringan uji coba di Yogyakarta dan Magelang  maka harus dilakukan coverage planning pada daerah yang kurang optimal. Kurang optimalnya daerah ini dikarenakan cakupan dan kualitas Radio Frequency (RF) masih belum memenuhi standar yang sudah ditetapkan oleh perusahaan. Hal ini terlihat pada hasil drive test daerah operasional. Solusi yang permanen, yakni pembangunan site baru dapat mengoptimalkan RF yang belum memenuhi standar perusahaan. Selain itu, untuk menjaga kualitas site baru agar tidak terjadi interferensi maka perlu dilakukan perencanaan Physical Cell Identity (PCI). PCI merupakan identitas site yang berbentuk kode angka 0 sampai 503. Parameter RF yang diteliti ialah Reference Signal Received Power (RSRP) dan Signal to Interference Noise Ratio (SINR). Analisis hasil drive test menurut parameter RF akan menghasilkan rekomendasi pembangunan site baru. Rekomendasi tersebut disimulasikan cakupan areanya dalam bentuk coverage prediction yang merupakan simulasi dengan planning tools U-Net. Dari hasil simulasi ini, didapatkan 50% cakupan area pada Yogyakarta memiliki RSRP  yang semula -99,17 dBm menjadi -98,78 dBm dan untuk Magelang yang semula -96,51 dBm menjadi -95 dBm. Sementara , SINR pada Yogyakarta meningkat rata-ratanya dari 1,03 dB menjadi 1,18 dB dan pada Magelang meningkat rata-ratanya dari 2,23 dB menjadi 2,55 dB.

Specific features of the test method procedure capable for determining the plasticity characteristic dH by indentation of inhomogeneous coatings affected by residual stress was clarified. When the value of the plasticity characteristic for coating was found to be as great as dH > 0.5 a simplified model was found to be reasonably adequate, while a modified model assumed compressibility of the deformation core beneath indentation. The advantage of the modified approach compared to the simplified one was grounded experimentally only if the elastic deformation for coating becomes greater than ?e ? 3.5%, resulting in the decrease of plasticity characteristic dH < 0.5. To overcome non accuracy caused by the effect of the scale factor on measurement results a comparison of different coatings was suggested using stabilized values of the plasticity characteristic dH determined under loads higher than critical, P ? Pc, ensuring week dependence of micro hardness values on the indentation load.

Perolehan persentase coverage site existing belum memenuhi standar KPI Operator untuk RSRP sebesar 78,491% ≥ (100) dBm dan CINR sebesar 65,698% ≥ (0) dB. Hasil optimasi physical tuninng antena sektoral menggunakan metode ACP sudah memenuhi standar KPI Operator untuk RSRP sebesar 90,037% ≥ (100) dBm dan CINR sebesar 94,868% ≥ (0) dB. Kata kunci: LTE, optimasi, physical tuning, Automatic Cell Planning, Atoll ABSTRACT The quality of the 4G (LTE) network is still unstable, causing bad coverage. To improve the quality of 4G network (LTE) can be done by sectoral antenna tuning optimization. Physical tuning of sectoral antennas includes changes in antenna height, azimuth and tilting antenna. In this study a sectoral antenna tuning physical optimization was carried out using the Automatic Cell Planning (ACP) method to meet coverage needs in West Purwokerto and North Purwokerto areas. The percentage of existing coverage sites has not met the KPI Operator standard for RSRP of 78.491% 100 (100) dBm and CINR of 65.669% ≥ (0) dB. The results of sectoral antenna tuning optimization using the ACP method have met the KPI Operator standard for RSRP of 90.037% ≥ (100) dBm and CINR of 94.868% ≥ (0) dB.
