A communication apparatus includes a detecting part which detects a bandwidth used by a first terminal equipment which performs radio communication, a communication speed measurement part which measures a communication speed of a second terminal equipment, a control part which generates a control signal controlling a communication of the second terminal equipment if a total bandwidth of a bandwidth detected by the detecting part and a bandwidth corresponding to a communication speed of the second terminal equipment measured by the communication speed measurement part is equal to or larger than a certain threshold value, and a restraint part which restrains communication of the second terminal equipment according to the control signal generated by the control part.
