The growing use of cellular technology has a rapid impact on the development of technology and information. This development relates to the use of information and communication services that is tailored directly, practically and effectively manner. Responding to the issue, the researcher is interested in conducting research by looking at the parameters using Time Division Duplex (TDD) technology and Frequency Division Duplex (FDD) technology on video streaming services. Service integrity measurement results on LTE networks are carried out in real time in the field according to the research path and eNodeB installed in dedicated mode. Dealing with the results, the effect of DT parameters on service integrity can only be seen in the SINR and CQI parameters. When SINR measured 21.3 dB and CQI measured 13.5, the measured throughput was 3665.2 Kbps so that the measured modulation was 64 QAM, on the other hand, if SINR measured -0.2 dB and CQI measured 10, the measured throughput was 0.5 Kbps so that the modulation measured was small, namely QPSK. From the results obtained, LTE TDD has a better service integrity value, namely throughput has a value of 891.16 Kbps and a latency of 48 ms for Telkomsel while 882.14 Kbps and latency was 49 ms for Smartfren than LTE FDD which had a throughput value of 820.83 Kbps and a latency was 68 ms for Telkomsel while 831.21 Kbps and 77 ms latency were for Smartfren, thus LTE TDD is better in terms of throughput and measured latency.

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 real signal quality measurement on the 4G network is a reference to improve signal quality. Measurements were made for two different operators on the Padang cluster. The measurement parameters taken are the RSRP value, SINR and throughput as the basic parameters of the KPI (Key Performance Indicator) standard. Measurement of these basic parameters is done by the drive test method using the Tems Pocket device while for data analysis using Tems discovery and Mapinfo Pro. Planning the data collection path is an important part to find out the bad spot areas of the two operators for planning signal quality improvement. The measurement results in the process of collecting data for bad categories and not being detected at all are used to determine the position of the new site by taking into account the three signal parameters, the number of users in the area, the minimum limit of the bad signal radius and the site positions that already exist for both operators. Using the cross method, three new site coordinate points are obtained, namely first at longitude 100.403428 ° and latitude -0.870309 °, second point at longitude 100.376331 ° and latitude -0.858726 °, and third point at longitude 100.404072 ° and latitude -0.966503 ° and 47 bad spot area.

Teknologi LTE merupakan teknologi generasi keempat yang diciptakan untuk memperbaiki teknologi generasi sebelumnya dalam hal layanan kecepatan transfer data. Kualitas layanan data akan semakin menurun seiring meningkatnya jumlah pengguna yang mengakses. Salah satu cara untuk menjaga kualitas layanan operator adalah menambah jumlah site. Kecamatan Bukit Sundi merupakan salah satu kecamatan di Kabupaten Solok, Sumatera Barat yang memiliki jumlah menara telekomunikasi yaitu dua menara. Kondisi ini menyebabkan tidak semua area mendapatkan layanan telekomunikasi. Untuk mengetahui kondisi kekuatan sinyal di lapangan dapat dilakukan dengan drive test.  Berdasarkan hasil drive test Kecamatan Bukit Sundi didominasi oleh RSRP kategori poor (RSRP -110 dBm sampai -100 dBm). Penambahan eNodeB baru dilakukan berdasarkan bad spot area. Setelah peninjauan lokasi eNodeB baru, didapatkan titik  longitude dan latitudenya. Untuk mendapatkan azimuth dilakukan simulasi sektor. Setelah diamati pada software atoll, setelah penambahan eNodeB baru terjadi peningkatan RSRP bagus (-95 dBm sampai  0) dari 14,5% menjadi 26,79%.

FDD (Frequency Division Duplexing) and TDD (Time Division Duplexing) Technology I is a duplex technology on the 4G LTE network. FDD technology in Indonesia is deployed in the 900 MHz, 1800 MHz and 2100 MHz frequency bands. Meanwhile, TDD technology uses frequency of 2300 MHz. In order to see the performance from the side of coverage, a measurement of the signal strength is conducted by direct measurements in field so that the appropriate technology and frequency band can be determined for the measurement area. The measurements have been done by two samples of different frequencies, namely 1800 MHz for FDD and 2300 MHz for TDD. Measurement of coverage is conducted on the same existing BTS and different BTS for both FDD and TDD modes. The parameter used in this measurement is the RSRQ value as one of the basic parameters of KPI (Key Performance Indicator). The results of drivetest data obtained the farthest coverage area of 789 m, namely the FDD (Frequency Division Duplexing) technology with frequency of 1800 MHz and TDD with frequency of 2300 MHz for 633 m.
