Abstract
Rapid advances in telecommunications systems are enabling people to enjoy various communication and information technologies. However, network service providers face challenges in maintaining and improving service quality, especially in terms of network coverage and quality in different regions. The solution to overcome poor coverage is to use an LTE-A signal amplifier. Signal amplification is in line with the need for Internet access speed. LTE-A technology offers a solution with many benefits for users and mobile operators. This study aims to design and implement improvements in the coverage and quality of the 4G LTE network in the suburban area of Kurao with an Outdoor Modem Mikrotik LTE-A Router. The addition of an outdoor modem signal booster plays a role in improving network performance without adding physical infrastructure, making it more efficient in terms of operational costs. Based on the results of the RF KPI measurements, the RSRP value increased from -107 dBm to -79 dB with the addition of the LTE-A Router outdoor modem. Similarly, the RSSI dropped from -76 dBm to -49 dBm. However, the RSRQ parameter remains in a fairly good indicator, which is less than -10 dB. For QoS measurement on QHD streaming with PTZ camera, the value meets very good standards for user experience KPI, namely packet loss, delay and jitter. And the bandwidth parameter has increased, the download bandwidth is 63.11 Mbps and the upload bandwidth is 31.58 Mbps
