ABSTRACT:
In an information processing apparatus such as a notebook type personal computer having radio communication functions, for communication units to simultaneously carry out transmission/reception independently of each other without increasing the number of antennas, and for sufficiently utilizing a diversity function in the case of only a portion of the communication units, there are provided antennas, communication units capable of carrying out radio communications through the use of the antennas, respectively, and a switching unit for switching connection states between the antennas and the communication units. When radio communications are simultaneously made through the use of all the communication units, the switching unit establishes connections between the communication units and the antennas while, when radio communication is made through the use of the communication unit, the switching unit connects the antennas, the number of which depends on communication modes of the communication unit, with this communication unit.
