Communication apparatus having first communication device conformed to a first communication standard and second communication device conformed to a second communication standard different from the first communication standard. With the above-described structure, said database and said two-dimensional matrix testing module can be connected with the computer mainframe such that the temperature control information can be transmitted to provide each heater of said heating section to generate a suitable temperature, heat the integrated circuit to be tested, and store the test information. The reproduction position andor the reproduction direction andor the reproduction speed of said signal isare modulated automatically with respect to the rhythm using control information in different predeterminable ways, based on information concerning the musical tempo. For example, by using a shorter background scanning interval during a telephone conversation, network connectivity performance may be maintained throughout the call.
