    • PROBLEM TO BE SOLVED: To provide a communication device capable of being tested in a simple manner at low cost. SOLUTION: The communication device includes: a first signal generator (101) generating a transmission signal with a first frequency; a transmission terminal (Tx) outputting the transmission signal generated by the first signal generator; a receiving terminal (Rx) receiving a reception signal; a mixer (106) mixing the reception signal inputted to the receiving terminal and the transmission signal generated by the first signal generator; a second signal generator (108) generating a test signal with a second frequency different from the first frequency; and a coupling circuit (111) coupling a line of the test signal generated by the second signal generator, with a line connecting to the receiving terminal to input the test signal into the mixer.

    • PROBLEM TO BE SOLVED: To test a performance of data transfer of a mobile device. SOLUTION: The quality of data transfer between wireless devices is tested by monitoring the performance of the protocol layers used by those devices. There are included a first tester communicated to a first device and a second tester communicated to a second device, and data are transferred between the two testers using an Internet protocol. A processor capable of analyzing data to be transmitted by an associated wireless device is integrated for each tester. Each of the processors determines a data transfer rate of each protocol layer in each device. Furthermore, these data transfer rates are displayed in real time so as to analyze how data are transferred from a capture application of the first device to a presentation application in the second device.
