Abstract

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.

Abstract

Currently, wireless telecommunication networks (wireless) have developed very rapidly. To meet the demands of today's mobile users for data rate transfer and data services. The application of LTE technology has been intensively carried out in several countries, including Indonesia. The problem that is often faced is the limited coverage area of ??the Base Transceiver Station (BTS) so that not all areas can be covered by the 4G network. Based on this background, this thesis will analyze the performance and signal quality of LTE networks in Malang City. This measurement is done using the G-Nettrack Pro application and the parameters to be measured in this study are RSRQ, RSRP, SINR and Throughput. The location of eNodeB used for research is in 2 Districts in Malang City. From the measurement results of the drive test, it was found that the area of ??Sawojajar and Malang City had a max RSRP value of -64 dBm, a min RSRP of -105 dBm, an average RSRP of -83.2 dBm in the Very good category. RSRQ max -6 dB, min RSRQ -11 dB, and average RSRQ -10.05 dB in the Normal category. SINR max 25 dB, SINR min -3 dB, and SINR average 9.65 dB in the Good category. Uplink max 14546 kbps, Uplink min 0, and an average Uplink 19.96 kbps in the Very bad category. Downlink max 15564 kbps, Downlink min 0, and downlink average 28.6 kbps in the Very bad category.

Abstract

The use of digital filters is needed by electronic systems, such as in signal and audio processing. The use of digital filters is to filter frequencies and modify the frequency spectrum of a signal so that the desired goal is obtained. The purpose of the filter is a series that passes a certain desired frequency band and dampens other frequency bands. The method used in designing the FIR filter is using the windowing method. There are several techniques included in the windowing method, namely rectangular, hamming, hanning, and kaiser. For the windowing work system it really depends on the type of window used, therefore there is a comparison between the four. This research will be developed by designing a digital FIR filter that is implemented on the raspberry pi device which is expected to be well integrated using the simulink matlab. So a study was made that raised the problem of how to process digital signals to apply the FIR filter using the windowing method that was simulated using the matlab program and implemented on raspberry pi. From the test results, it can be seen that the Raspberry pi can be integrated well using the Simulink matlab. The bigger the ripple, the stopband attenuation, and the bandwidth width on the result of the signal output frequency response affect the resulting order, that is, the smaller it is.

Abstract

The problem that exists on the server for video call services is that the use of the server usually uses a PC that has FreePBX installed and requires some hardware that must be provided, such as a CPU with 312 MB of memory specifications used, 800 MHz Pentium III CPU. There is an alternative to building a server with better specifications than conventional CPUs in supporting video call services using a Mini PC. One type of popular Mini PC is the Raspberry Pi. Based on the results of a comparative study, two Mini PC servers are able to serve customer capacity at video resolution for the H264 codec. Two Mini PC servers are able to serve as many as 10 client video call communications with CPU and RAM usage on the Raspberry Pi 4 compared to the Raspberry Pi 3 with an average CPU usage of 39.8% and RAM Usage 282 MB viewed using the HTOP command on putty. Determination of the amount of user capacity is determined based on the number of clients communicating simultaneously, and the CPU and RAM usage on the Mini PC.

Abstract

Voice chat application is an application designed to replace the HT function on an Android smartphone. Besides being able to make voice calls, this application can be used to communicate with text. This application does not require cellular networks to communicate, simply by connecting to a network provided by an existing access point. The applications can be used without using a cellular network, when making an application requires a socket. Socket is an API that exists on Android studio software. While socket programming is a way to use socket components to create an application, one of which is a voice chat application. After being installed in android smartphones, each smartphone is connected to a network provided by an existing access point so that it can communicate by voice or text. Communication is carried out between smartphones with one another point to point. The test results can be concluded that this application can be used to communicate with voice and text, as long as the user is on the same network. This application can be used in all types of Android mobile phones for voice communication but communication with text can only be used on certain mobile brands.

Abstract

Motorcycle are movable objects that become public transportation needs. Motorcyclists include people from various backgrounds have experienced accidents. One of the causes of accidents is the speed. Motorcycle that has accident will fall and get injured. The need to know the cause of the accident requires investigation and analysis. Data needed to analyze traffic accidents such as vehicle operating speed and location of the accident. Required data can be obtained by utilizing infrared sensor as motorcycle speed sensor, gyroscope sensor for indicators of falling or not motorcycle and GPS to determine the coordinate points of movement motorcycle. This information is communicated using GSM module. The information is sent to the database and then displayed via Android application and the data log is stored on smartphone storage. Based on the results of tests carried out, it is known that accuracy of the speed sensor readings is 98.39% from 12 tests. The GPS test tool compared to Garmin GPS has an average difference of 3.14158 meters. The fall indicator can function properly when falls and the data can be viewed via Android application. The data is stored on smartphones and in firebase storage. The average delay test is 7,087 seconds.
