This work proposes analysis effect of environmental parameters on Global System for Mobile Communication (GSM) and Global Positioning System (GPS). This paper presents variation in GSM signal strength with respect to weather parameters. There are many sources of deviation for both issues, but into this research our main focus on Tropospheric delays. The results show humidity, pressure, temperature and air condition effect signal strength values of GSM and accuracy of GPS. The minimum and maximum measurements were recorded for GSM in the range - 89 and - 41 dBm where -89 is low signal strength and -41 is high signal strength. The accuracy of GPS were calculated and compared at different points. Result of this research showed that the tropospheric delay produce 6 to 14 meters deviation on same landmark at different weather parameters value.
