Abstract

Hindarto Joesman Building, Faculty of Medicine is one of the lecture buildings at Jenderal Achmad Yani University which consists of 4 floors and has a building area of ??4125.6 m². The building has a low signal quality for the indoor LTE network. This is due to the construction and materials in the building which can weaken the quality of the LTE signal received. These conditions make the Faculty of Medicine UNJANI building require a separate indoor network installation to cover user needs inside the building. Indoor Building Coverage planning for this building can help to improve signal level and value of Reference Signal Received Power (RSRP) and Signal to Interference Noise Ratio (SINR). The process of calculating coverage planning in indoor network planning uses the Cost propagation model 231 Multi Wall Model and is simulated in the Radiowave Propagation Simulator 5.4 software. Based on the simulation results, the average RSRP value is -20.59 dBm and SINR is 34.30 dB. The average value can cover the signal quality in the building area of ??89.12% for RSRP and 97.45% for SINR. The results of the planning and simulation of the Indoor Building network have met the standard RF parameters for operators.

Abstract

Teknologi LTE-Advanced menghadirkan fitur baru bernama femtocell atau disebut juga Home Enhanced NodeB(HeNB) yang dapat meningkatkan area cakupan indoor. Di lain sisi HeNB menimbulkan interferensi baik uplinkmaupun downlink. Interferensi uplink terjadi antara user HeNB (HUE) dan user eNB (MUE) maupun sesamaHUE. Interferensi ini mendegradasi kinerja sistem terutama dari sisi Signal to Interference plus Noise Ratio(SINR). Pada penelitian ini, dilakukan manajemen interferensi di sisi uplink dengan menggunakan metode powercontrol. Power control mengatur daya pancar user penginterferensi sehingga daya interferensi pada sisi HeNBdan eNB berkurang dan nilai SINR akan membaik. Uplink power control yang dilakukan pada penelitian iniberdasarkan algoritma Overload Indicator, dan diharapkan dapat mengoptimalkan kinerja dan mengurangiinterferensi.

Abstract

Pemanfaatan komunikasi teknologi 4G diharapkan menghasilkan kecepatan jaringan sangat cepat bagi para pengguna. Namun, teknologi 4G ini memiliki beberapa kendala yang menyebabkan kecepatan jaringan menjadi berkurang dan tidak optimal. Untuk mengatasi hal tersebut maka perlu dilakukan optimasi jaringan untuk memperbaiki kualitas jaringan agar dapat dipakai dengan optimal. Pada penelitian ini dilakukan proses optimasi untuk memperbaiki kondisi level sinyal Reference Signals Received Power (RSRP) khususnya di area Bandung Timur. Proses optimasi dilakukan dengan menggunakan metode electrical tilt. Optimasi dilakukan dengan menganalisis kondisi level sinyal RSRP aktual berdasarkan hasil drive test kemudian disimulasikan dengan menggunakan Atoll Planning Software. Berdasarkan hasil drive test, didapatkan 7 area badspot dengan level RSRP di bawah -100 dBm, dan area tersebut merupakan area dengan aktifitas kepadatan penduduk yang tinggi. Setelah dilakukan simulasi optimasi electrical tilt dari beberapa site yang telah ditentukan berdasarkan hasil analisis, terdapat perbaikan kondisi level sinyal RSRP jika dibandingkan dengan kondisi aktual. Perbaikan ditunjukkan dengan adanya kenaikan persentase untuk RSRP > -100 dBm dari 83,379% menjadi 86,066%, dan juga terjadi penurunan RSRP < -100 dBm yaitu dari 17,621% menjadi 13,934%. Hal tersebut menunjukkan optimasi yang dilakukan dapat memperbaiki kondisi level sinyal RSRP di area Bandung Timur.

Abstract

Gedung Fakultas Psikologi Universitas Jenderal Achmad Yani (Unjani) merupakan gedung perkuliahan yang berada di lingkungan kampus Unjani dan belum memiliki instalasi sistem jaringan indoor. Kondisi tersebut menyebabkan level sinyal yang terukur di dalam gedung memiliki nilai RSRP lebih kecil dari -110 dBm. Level sinyal tersebut termasuk dalam kategori kualitas sinyal 4G yang kurang baik. Selain itu faktor lain yang menyebabkan pelemahan sinyal ialah material dan konstruksi bangunan tersebut. Oleh karena itu, agar user pada gedung tersebut dapat terlayani dengan baik, solusi yang dilakukan adalah melakukan perencanaan jaringan Indoor Building Coverage (IBC) 4G. Berdasarkan perhitungan coverage planning jumlah antena yang diperlukan dalam perencanaan sebanyak 14 antena yaitu lantai 1 dan 4 masing-masing sebanyak 3 antena, lantai 2 dan 3 masing-masing sebanyak 4 antena. Berdasarkan hasil simulasi pada software RPS diperoleh persentase nilai rata-rata nilai RSRP >-90 dBm sebesar 89,93 % dan persentase rata-rata nilai SINR >3 dB sebesar 87,95 %. Berdasarkan hasil simulasi tersebut didapatkan bahwa hasil perencanaan yang telah dibuat telah memenuhi standar operator dan dapat diterapkan untuk memperbaiki coverage dan meningkatkan level sinyal di Gedung Fakultas Psikologi Unjani.

Abstract

Pada sistem komunikasi baik analog maupun digital, suatu sistem komunikasi memerlukan proses modulasi. Modulasi merupakan proses pengkodean informasi dari sumber pesan menggunakan cara yang sesuai dengan proses transmisi. Hal ini dilakukan agar sinyal informasi dapat dikirimkan dan diterima dengan baik di penerima. Pada teknologi 4G LTE terdapat 3 jenis modulasi yang digunakan yaitu Quadrature Phase Shift Keying (QPSK), 16-Quadrature Amplitude Modulation (16-QAM), dan 64-Quadrature Amplitude Modulation (64-QAM). Modulasi tersebut akan berpengaruh terhadap data rate yang diterima di pelanggan. Pelanggan akan menerima data rate yang optimal, jika pelanggan mendapatkan modulasi 64-QAM. Akan tetapi, tidak semua pelanggan bisa mendapatkan kondisi 64-QAM. Terdapat beberapa hal yang mempengaruhi tipe modulasi yang dapat diterima oleh pelanggan, salah satunya adalah level sinyal yang diterima oleh pelanggan. Pada penelitian ini, penelitian dilakukan di area Kota Cimahi yaitu area sekitar site Puri Fajar Cibeber. Berdasarkan hasil analisis, didapatkan bahwa tipe modulasi QPSK selalu mendukung untuk disemua kondisi level sinyal baik level sinyal yang bagus yaitu RSRP > -90 dBm dan SINR > 0 dB maupun kondisi level sinyal yang kurang bagus yaitu RSRP < -90 dBm dan SINR < 0 dB. Sedangkan untuk tipe modulasi 64-QAM sebanyak 40,4% didapat jika kondisi level sinyal RSRP-nya berada di atas -90 dBm.

Abstract

Utilizing of 5G technology has become a major focus in the development of more advanced and efficient telecommunications networks. In this context, 5G coverage prediction becomes an important aspect in network planning to ensure optimal user experience. In this study, we explore the use of Random Forest algorithm to predict 5G coverage, with special emphasis on the hyperparameter optimization process to improve model performance. We conduct experiments with various hyperparameter combinations, including 'max_depth', 'max_features', 'min_samples_leaf', 'min_samples_split', and 'n_estimators', using hyperparameter optimization techniques. The results show that by paying attention to the optimal combination of hyperparameters, we managed to significantly improve the performance of the model. The optimized model produces a Minimum Root Mean Squared Error (RMSE) of 0.6, which is much better than the Random Forest model without hyperparameter optimization which has an RMSE of 1.14. The result of this study confirms the importance of the hyperparameter optimization process in improving the accuracy and consistency of the Random Forest model for 5G coverage prediction. The results have important implications in supporting the development of a successful 5G network infrastructure in the future.

Abstract

5G New Radio (NR) services can provide high data rates and low latency. The existence of 5G technology, especially in Indonesia, has been implemented by several cellular operators in the 2300 MHz and 1800 MHz frequencies. Therefore, a more detailed planning analysis is needed, especially in urban areas. In this study, planning for the 5G network needed in one of the urban areas in Cimahi City, West Java. This research was carried out for a frequency of 2300 MHz using the coverage planning analysis method. The propagation model used in this study is 3GPP TR38.900. Based on the analysis and calculations performed, obtained 26 sites for the area of ​​Cimahi City which has an area of ​​about 40.3 km². The location of the site is arranged based on the coverage conditions in the area and also based on the distribution of the 4G network that previously existed in the area, because the 5G planning used is the Non-Standalone 5G type. Based on the results of the coverage analysis carried out, the condition of the Synchronization Signal Reference Signal Received Power (SS-RSRP) signal level above -90 dBm reached 27.3% of the total area. This shows that the 5G network planning in this area can only cover an area of ​​up to a quarter of the total area.
