Perencanaan sistem jaringan LTE dipengaruhi oleh beberapa faktor, salah satunya adalah faktor kontur wilayah yang berbeda. Kontur permukaan wilayah berpengaruh terhadap cakupan area yang dihasilkan suatu base station. Perencanaan jaringan berdasarkan analisis perhitungan, tidak mempertimbangkan kontur wilayah, maka untuk menunjang hal tersebut diperlukan simulasi menggunakan software Atoll. Metode pada penelitian ini menggunakan perhitungan dan simulasi software Atoll. Penempatan base station memanfaatkan 385 Bale Banjar sebagai titik site menara rooftop. Penempatan ini dilakukan di Bale Banjar dikarenakan mudahnya akses perijinan tempat, seperti base station pada Bale Banjar Balun. Berdasarkan hasil perhitungan dan pemodelan simulasi jarak jangkauan antena base station dengan model propagasi Cost-231 Hatta frekuensi 1800 MHz, diperoleh jarak sebesar 1,186 km. Simulasi perencanaan sistem LTE di wilayah kota Denpasar memerlukan 55 site, terdiri dari 54 site yang memanfaatkan Bale Banjar untuk menempatkan base station dan 1 site di luar kawasan Bale Banjar, serta diperlukan pengaturan electrical tilt sebanyak 40 site untuk mengatasi permasalahan cakupan area.

Pengimplementasian Long Term Evolution (LTE) di Bali mengalami kendala terutama dalam menjaga performansi jaringan yang diakibatkan oleh lonjakan data yang semakin meningkat dan kualitas coverage yang kurang maksimal. Maka perlu dilakukan pemeliharaan jaringan untuk mengetahui kualitas dari suatu jaringan yang dapat dilakukan melalui pengamatan secara real di lapangan dengan pengukuran parameter 4G LTE pada suatu wilayah yang belum optimal. Metode yang digunakan adalah dengan melakukan Drive Test menggunakan software GENEX Probe dan analisa hasil drive test menggunakan software GENEX Assistant. Adapun parameter yang diukur antara lain RSRP, SINR, RSSI, RSRQ, CQI, PCI dan PDCP Throughput yang kemudian dibandingkan dengan standar KPI XL. Hasil dan analisa diperoleh nilai RSRP sebesar 93,36% > -105 dBm, SINR sebesar 91,14% > 3 dB, PDCP DL Throughput sebesar 92,18% > 5 Mbps dan PDCP UL Throughput sebesar 88,73% > 3 Mbps yang belum memenuhi standar KPI XL sebesar 95% diakibatkan oleh faktor variasi obstacle sehingga terjadi area bad spot pada beberapa titik wilayah. Optimalisasi yang dilakukan menggunakan metode mekanikal tilt dengan mengubah tilt antena dari 20 menjadi 30 pada area bad spot menyebabkan peningkatan performansi RSRP sebesar 3,49%, SINR sebesar 5,91%, PDCP Download Throughput sebesar 4,7% dan PDCP Upload Throughput sebesar 10,73% dari standar Key Performance Indicator (KPI) XL.

Drop call is an example of a problem that is often experienced by users of voice telecommunications services. From this condition, this riset raises the topic of drop call analysis on WCDMA networks in the Renon cluster (nodeB MYAMIN_CR, AKABA_PL, and BUNDARANRENON_PL). Data retrieval needed (Call Set Up Success Rate (CSSR), Call Drop Ratio (CDR), RSCP and Ec/No) is done by drive test using G-NetTrack Pro software. Based on the analysis of the results of the drive test, there were 10 drop call problems. The problems indentified cause by missing neighbors, handover failure, bad spot, coverage problems and overshoot. Bad spots, coverage problems, and overshoot are the initial causes of missing neighbors and handovers failure. Missing neighbors and handover failure begins with the poor value of RSCP and Ec/No, so that the cellphone will try to do a handover. To analyze the drive test results, drive test data is carried out using Atoll software. From the comparison found extreme conditions resulting from obstacle which cause a significant difference in value between the results of the drive test and simulation. The high attenuation rate drop call location due to the obstacle also results in RSCP and Ec/No values being obtained when measurements in the field are low. The low parameter values of RSCP and Ec / No then cause a drop call.

Saat ini Teknologi video digital banyak digunakan pada aplikasi hiburan, contohnya adalah TV Digital dengan format HD. Dengan frame rate tinggi, pengkodean video akan menghasil laju bit lebih tinggi yaitu sampai 15 – 30 fps. Permasalahannya adalah kapasitas saluran transmisi memiliki kapasitas terbatas. Solusinya adalah menurunkan laju bit dengan menurunkan jumlah frame video ke penerima. Skema ini dikenal dengan Frame Rate Up-Conversion (FRUC) video, dimana frame yang di encoder akan direkonstruksi kembali di decoder dengan membangkitkan frame intermediate (FI). FI dibangkitkan dengan teknik Motion Compensation Interpolation (MCI). Terkait dengan metode FRUC, penelitian ini mengajukan skema MCI unidirectional dengan pencarian gerak akurasi setengah piksel. Pada skema ini, sebuah motion vector (MV) kandidat akan dicari di frame referensi, proses estimasi gerak dilakukan dengan menambah piksel sisipan diantara piksel eksisting. Sasarannya adalah meningkatkan akurasi MV kandidat. Hasil simulasi menunjukkan bahwa metode yang diajukan lebih baik sampai sebesar masing – masing 3,21 dB dan 3,11 dB pada wilayah pencarian 7 dan 15 piksel dibandingkan dengan metode frame repetition untuk sekuen video foreman dan hall monitor.
