Abstract

Long Term Evolution (LTE) is a long-term evolutionary radio access network released by the 3rd Generation Partnership Project (3GPP), LTE is a continuation of the third generation technology, namely 3G WCDMA-UMTS. LTE speeds can reach 100 Mbps on the downlink and up to 50 Mbps on the uplink. This feature has resulted in a large number of LTE network users both in urban and rural areas, especially at a time like now that demands all work to be based on Work From Home. The Bergas Sub-district, Semarang Regency is an example of the large number of LTE service users so that a new site was built, namely the UNR134 site, but previously in this area there were already 2 existing sites namely UNR034 and UNR018 so that optimization was carried out both on the UNR134 site and also on the UNR034 and UNR018 sites. In this study, optimization simulations were carried out using Atoll software using the physical tilt method consisting of mechanical tilt and electrical tilt2. Abst, and re-azimuth at 4 sectoral antennas between 3 sites.. Parameters that will be observed in this study include RSRP, and SINR. In this study, the mean RSRP value increased from -81.3 dBm to -81.02 dBm, but on the SINR side it decreased from 5.25 dB to 4.74 dB. Keywords : Re-Azimuth, Physical Tilt, RSRP, SINR, Atoll
