Abstract

The development of Internet use has spurred Wireless Sensor Networks (WSNs) technology so that it becomes a widely researched and applied device. With the need to use high WSNs, the quality of features provided such as high data transfer speeds and the smallest possible disruption is something that should be available. Although some uses of WSNs do not require high speed and have a tolerance for interference, there are very few types of use. Nevertheless, routing protocols are provided to meet the types of data transfer requirements. The protocols available for each type will be analyzed and compared to find out the best performance.Keywords: data transfer, routing protocol, WSN.

Abstract

This research was motivated by a decline in performance on the BTS Batang Marau, which indicates the level of Rx Level, Rx Qual and SQI not meet KPI targets, so the presence of the area around the base stations that do not meet the standard Rx Level to make phone calls (blankspot). The purpose of this study was to determine the performance of GSM 900 and 1800 networks, as well as to improve the performance of base stations Batang Marau Power Link Budget calculation method. This study discusses the improving performance of GSM network at the site decreased performance, where performance is observed through measurement results based on the data drive test. The results of data analysis showed : (1) From the analysis, GSM 1800 already meet KPI targets for Rx Level >95 %, Rx Qual >94 % and SQI >93 %. In GSM 900 results analysis and Rx Qual SQI already meet the target KPI Rx Qual  >94 % and SQI >93 %, while the results of the analysis of Rx level at 09.00 already reached the target KPI >95 %, at 15:00 and 20:00, still has not reached the target KPI <95 %, which indicates the time of measurement using tools Tems Investigation, there are several areas that Rx the level of poor quality. (2) Value Rx level in the area around the base stations are <-95 dBm indicates blankspot area (can lead to a drop call). (3) The estimated increase in performance on the GSM network by the method of link power budget on the BTS Batang Marau  shows 69.3 dBm Rx Level (Good quality) at a distance of 2.5 km, so it can be concluded that the performance of GSM 900 base stations have been increased Batang Marau performances.

Abstract

This research was conducted on the basis of the weakness of the received signal by service users (MS) caused by certain factors such as the geographical structure of a city, many buildings so that the path loss (Path Loss) resulted in data connection failure or call failure. This study serves to determine the comparison of Pathloss values in the Medium-Sized City and Large City Regions in Padang city with a 231-Hata cost propagation model. The measurement method used is the drive test using the Network cell Info LTE application and then analyzed with a model cost 231-Hata, the results of measurements with the RSRP standard research were carried out in the morning and evening for five days. The results showed: In Air Tawar BTS (Large City) by measurement and calculation of the Cost 231 Hata model, compared to the RSRP PT.XL Axiata Padang standard, the signal quality is medium category. While the Lubuk Buaya (Medium-Sized City) BTS is measured, and in the calculation of the Cost 231 Hata model. Compared to the RSRP PT.XL Axiata Padang standard, the signal quality is in Medium category. From the results of measurements and calculations there are differences in pathloss values that are not too significant. This is due to several factors such as building height, road width and geographical structure of the area.Keywords: RSRP, Pathloss, Drive Test, Cost 231 Hata,4G LTE

Abstract

Based on the survey data of optical fiber service, the communication network uses optical fiber transmission medium is not maximal yet, because there are some errors in the network, such as the percentage of Network Post Dialing Delay in system is 97.5%, that means there is 2.5% of error a delay occurs in the network when making a call. This research was conducted by analyzing the fiber attenuation of fiber-optic communication systems performance on the link Padang-Bukittinggi in PT. Telkom Padang, SKSO division which uses single mode fiber optic cable types G655. Instrument in this study is the Power Meter and OTDR JDSU MTS-6000 type. Link Power Budget method is used to determine the performance of optical fiber communication systems caused by attenuation based on the value of the received power output. Obtained results on the link Padang-Bukittinggi highest attenuation occurs in core 5 with 26.7226 dB attenuation value and cable length 115 016 km, and in core 7 with 26.1812 dB and cable length 94 462 km. This value is still below of PT. Telkom standard with 28.10352 dB for core 5. While the attenuation value at 7 cores exceeds standard attenuation values​​, with 24.18186 dB, so the performance of the core is declared bad and needs to be evaluated. From optical fiber attenuation value, result of the link power budget analysis is obtained from the calculation of the value of Rx is smaller when compared with -27 dBm the value of Rx sensitivity, it can be said the performance of optical fiber communication systems on the link in the normal state and can be used to operate because the power output can be accepted by the receiver in the device. Keywords: fiber optic cable, optical fiber attenuation, SKSO, link power budget.
