Despite continuous infrastructure enhancements, signal degradation caused by terrai n characteristics, environmental obstructions, and suboptimal base station placement remains a critical issue, highlighting the need for efficient analysis and visualisation tools. This study presents a MATLAB Graphical User Interface (GUI)-based framework for spatial analysis of Received Signal Strength Indicator (RSSI) and Signal - to-Noise Ratio (SNR) in Parit Raja, Johor, which supports effective network diagnostics and data - driven optimisation for improved cellular performance. Field measurements were acquired using a MikroTik  LtAP  LR8G  LTE6  kit  with  integrated  GPS,  enabling  accurate  geo -referenced  data collection. The proposed system automates data preprocessing, spatial interpolation, an d heatmap visualisation  to  facilitate  efficient  and  intuitive performance  evaluation.  The analysis  of  Maxis cellular coverage in Parit Raja shows that RSSI values range from \u221245 dBm to \u221285 dBm, while SNR varies between \u221210 dB and 30 dB. Strong signal conditions are observed in open areas, whereas weaker performance is evident in dense and obstructed environments, demonstrating significan t spatial variability.<\/p>\r\n        \r\n                    <p><strong>Keywords:<\/strong>\r\n                cellular network, heatmap, MATLAB GUI, RSSI, SNR, wireless communication            <\/p>\r\n            <\/div>\r\n\t\r\n\t\r\n\t\r\n\t<div class=\"asmsj-citation-box\">\r\n        <h3>How to Cite<\/h3>\r\n        <p id=\"citation-text\">\r\n            2026.
