Analysis of Link Budget is expected to be a reference as a first step in planning the WLAN radio between the Panam Riau University and the Gobah Riau University. In this Research, will compare the result of Link Budget calculations for 2,4 GHz WLAN radio connection between the method of computation used Radio Mobile software version 9.5.0 with a theoretical calculation method. Link Budget analysis obtained demonstrated by the System Operating margin (SOM) which is worth 27 dBm,which has exceeded the treshold value of SOM are both in the design of radio communication is 15 dBm.otherLink BudgetWLANRadio MobileSystem Operating Marginstudent Paper Post Degree
