Abstract

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.RTM. (BT) modules {circle around (1)} and {circle around (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 around (4)}; a wireless terminal 3 including a third BT module {circle around (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 around (1)} is a master and the third BT module {circle around (3)} is a slave, and the second, fourth, and fifth BT modules structure a second Piconet in which the fourth BT module {circle around (4)} is a master, and the second and fifth BT modules {circle around (2)} and {circle around (5)} are slaves.
