1. A wireless communication device, comprising:

  • a first wireless communication section for performing first wireless communication using a first frequency band; and

    a second wireless communication section for performing second wireless communication using a second frequency band,wherein the second wireless communication section transmits/receives data by the second wireless communication and outputs a communication status signal that represents a signal pattern corresponding to a communication status of the second wireless communication,the first wireless communication section analyzes the pattern of the communication status signal,wherein the communication status signal is a digital signal that is set to a first value during communication and is set to a second value during non-communication, andin case that the communication status signal has not become the first value in a predetermined period, the first wireless communication is not performed;

    in case that a total time, during the predetermined period, when the communication status signal has been the first value is a predetermined time or more, the first wireless communication section determines that the second wireless communication is in a congested state;

    in case that the same signal pattern based on a period where the communication status signal pattern based on a period where the communication status signal is the first value and a period where it is the second value, has been detected plural times during the predetermined period, the first wireless communication section determines that the second wireless communication is synchronous; and

    in the other cases, the first wireless communication section determines that the second wireless communication is asynchronous.
