Nowadays, one of the communications technology has existed to improve telecommunication efficiency is the technology of 4G Long Term Evolution (LTE). Some factors affect network quality, such as signal strength and quality of service. This study discusses the correlation between signal strength and the Reference Signal Received Power (RSRP) parameter on the quality of service with throughput and jitter parameters. This research is conducted by drive test method using the software G-Net Track Pro and SpeedTest, the network provider used is the provider Tri 4G LTE with a 15-point research sample at Malioboro street, Yogyakarta. The results of the research and measurements showed the average RSRP value of -82 dBm and RSRQ amounted to-13 dB. The average throughput measurement is 1 Mbps, the average measurement of jitter is 86.5 ms and the average packet loss is 0%. While the usual average night throughput is 1.4 Mbps, Jitter is 33 ms, and Packet Loss is 0%. The result showed that signal strength is affecting the quality of service. 80% or 13 sample research points show that signal strength is linear towards the quality of service. The correlation mismatched occur at point 13, point 14, and point 15. At all three points, the RSRP is well-priced even with a range of values of-72 dBm to-83 dBm, but the quality of service for throughput and jitter parameters is very poor with a throughput range of 0.4 Mbps to 1.2 Mbps and jitter with range value 93 ms to 130 ms. Results analysis showed the correlation between the signal strength to the quality of service occurs when the signal strength in this research RSRP parameter has a good value then the quality of service for the throughput and jitter parameters also have a good value.
