Japanese Patent JP4077631
Kind Code:
B2
Abstract:
A wireless communication apparatus, a wireless communication method thereof, and a wireless communication system employing the same. A master device (U1) of the wireless communication system requests one slave device (U2) to perform temporarily a function of a master device for a predetermined time, and sends Piconet information about other slave devices (U3). The one slave device (U2) receives the Piconet information from the master device (U1) and communicates with the other slave devices (U3) of the network for a predetermined time as a temporary master device. Accordingly, the one slave device (U2) becomes a dynamic master device and communicates with the other slave devices by using a frequency hopping sequence and a clock of a previous master device (U1). There is no need to transmit the frequency hopping sequence and the clock of the new master device to the slave devices, and accordingly, much time can be saved.
