PROBLEM TO BE SOLVED: To provide a method capable of estimating an antenna power of a walkie-talkie inexpensively regardless of the direction of a transmission/reception antenna without requiring complicated operation. SOLUTION: In a walkie-talkie radio wave transmission step 1, a radio wave is transmitted from the walkie-talkie in a reflection box 5. In a walkie-talkie radio wave reception step 2, the radio wave transmitted from the walkie-talkie is received by a reception antenna in the reflection box 5. In a field intensity cumulative distribution function calculation step 3, the statistic of the received radio signal of the walkie-talkie is measured by using a statistic measuring device 6, and the field intensity cumulative distribution function in the reflection box 5 is calculated. In an antenna power estimation step 4, the antenna power of the walkie-talkie is estimated based on a cumulative probability 63.2% of the calculated field intensity cumulative distribution function and a reflection box loss calculated beforehand.
