A wireless network system for enabling good communications, while minimizing the electricity consumption of a portable terminal, is described. Included are: a first relay device 4a including first and second Bluetooth(R) (BT) modules {circle over (1 and {circle over (2. Each of the BT modules performs a cable communication irrespective of which is a master/slave. The system also includes a second relay device 4b including a fourth BT module {circle over (4; a wireless terminal 3 including a third BT module {circle over (3; and a wireless terminal 3 including a fifth BT module. The first and third BT modules structure a first piconet in which the first BT model {circle over (1 is a master and the third BT module {circle over (3 is a slave, and the second, fourth, and fifth BT modules structure a second Piconet in which the fourth BT module {circle over (4 is a master, and the second and fifth BT modules {circle over (2 and {circle over (5 are slaves.
