![]() The Cost-231 MWM plays a role in estimating the measured power received by user (usually called as Received Signal Strength Indicator/RSSI) by considering the existence of obstacles around the transmitter (AP). This approach used as a reference for access point (AP) placement for campus building. ![]() Of research results also gained some room located near some of the access point are having Signal to Interference Ratio-(SIR).Ī new approach has been developed to provide an overview about signal behavior in indoor environments using Cost-231 Multiwall Model (Cost-231 MWM) and Adaptive Data Rate (ADR) method. Experimental results indicate the quality of the reception on location observed is not the same, some point receive very strong signals from more than one access point, while some other point still entered into the realm of blankspot. ![]() The analysis performed includes: Signal level, Signal-to- Interference ratio, and Quantity of Access point. The research method used was the experiment through the drive test using Nestpot software. This research aims to map the territory of blankspot on that location, so that it can be used as a reference for optimizing the placement of access points. On the research of the simulation is done against the signal strength of the access point toward the receiver Wi-Fi in the room and the room of the student learning lecturer electrical engineering building FPTK UPI 3 and 4 floors. Installation of the access point is often not structured properly so that the area of scoped in the area of coverage is uneven. The requirement to always be connected to the internet network is seen with the growing number of access points that are installed to meet these needs. Currently the ease of accessing the internet has become a fundamental requirements primarily a college surroundings.
