CONSTITUTION: A packet error measurement unit(310) measures a packet error number during a call using a WiFi phone. If a continuous packet error number measured in the packet error measurement unit is larger than a preset reference value, a beacon signal receiving unit(330) checks whether a beacon signal is received. If the beacon signal receiving unit does not receive the beacon signal, a beacon signal measurement unit(340) measures the number of beacon signals which are continuously failed. |
