Optimization of 4G LTE (Long Term Evolution) Network Coverage Area in Sub Urban.

Nowadays, 4G LTE (Long Term Evolution) telecommunication technology that has spread throughout Indonesia is growing rapidly. However, the coverage of 4G LTE has not been implemented well in Indonesia, one of them is in Sragen. So to be able to increase the quality of 4G LTE network, it is necessary to optimize the coverage area of 4G LTE network in Sragen by using the physical tuning method, which is to adjust the antenna tilt, azimuth antenna, power. Key Performance Indicator is a reference to determine the performance of a network. The measured parameters are reference signal reception power (RSRP), reference signal reception quality (RSRQ), signal interference noise ratio (SINR). The results from the optimization are the percentage of RSRP was initial 45.87% to 75.58%, an increase of 29.72%. While the RSRQ value increased by 20.78%, with an initial value was 27.84% to 48.62%. SINR increased by 5.29% with an initial percentage was 4.87% to 10.16%. [ABSTRACT FROM AUTHOR]
