The existing wireless networks at Muhammadiyah University of Yogyakarta Building F1 and F4 are based on Path Loss, Signal Strength / Isotropic Receive Level (IRL), and Signal to Noise Ratio (SNR) parameters. The research used the calculation method of COST 231 Multiwall Indoor and Ekahau Site Survey modeling, then analyzed and compared with the network quality reference standard of the parameters. In this study it was concluded that the network quality in Building F1 and F4 based on RSSI is divided into 3 categories, Very Good (-57 dBm to -10 dBm), Good (-75 dBm to -58 dBm) and enough (-85 dBm to -76 dBm). While the quality of network based on SNR for short distance is Excellent (> 40 dB), medium distance is Low Signal (15 dB - 25 dB) and Very Good Signal (25 dB 40 dB), long distance Very Low Signal (10 dB - 15 dB ), Low Signal and Very Good Signal.
