Indoor Signal Quality Improvement using Coverage Planning Method in Indoor Building Coverage Simulation

Abstract

A building, especially apartments, not all of them have indoor network system installation. This condition causes the building doesn’t have good network signal quality, especially in this study were observed LTE network. We can say that signal condition isn’t good when we compare to the quality of indoor signal not as good as with outside the building. In addition to the construction and building materials also many other factors that cause signal attenuation. One solution that can be done to overcome the problems that occur is by planning the installation of Indoor Building Coverage (IBC) in the LTE network. In carrying out the design of LTE IBC is analyzed to perform the IBC planning to analyze in terms of capacity and coverage. Through the coverage and capacity planning calculations found the number of antennas required in the plan that is 172 antenna. Based on simulation results obtained an average RSRP range from −50 to −74 dBm and SINR with an average range of 14 to 67 dB. By comparing the simulation results with the standard values of parameters in one of the national provider operator (XL) found that the plan meets the standards that led to the building operator increased coverage.
