Abstract

Getting connected with acceptable performance is always a user expectation. Moreover, it is critical when network users are in a mobile position. Receiving an adequate level of signals ensures the users get a good signal to noise ratio (SNR) which then promotes good data connections. Furthermore, measuring the signal from a user perception is always important for optimizing the network coverage. This work proposes a scanning process in a range of frequency to asses the coverage. By the use of software-defined radio (SDR), the research has performed measurement in LTE frequency band 3 in a defined track in the City of Yogyakarta. With a low-cost device, some valuable information such as the actual bandwidth used and the benchmark between operators can be obtained. For instance, the measurement acquired a result that an operator leads covering the track by around 5dB.
基于SDR技术的LTE频率移动扫描
以可接受的性能连接始终是用户的期望。此外,当网络用户处于移动位置时,这一点至关重要。接收足够水平的信号可确保用户获得良好的信噪比(SNR),从而促进良好的数据连接。此外,测量来自用户感知的信号对于优化网络覆盖总是很重要的。本工作提出了一种频率范围内的扫描过程来评估覆盖范围。通过使用软件定义无线电(SDR),该研究已在日惹市的一个定义轨道上的LTE频段3进行了测量。使用低成本的设备,可以获得一些有价值的信息,如实际使用的带宽和运营商之间的基准。例如,测量获得的结果是,操作员导致轨道覆盖约5dB。
