DEVICE, METHOD AND SYSTEM FOR EXCHANGE OF INFORMATION BETWEEN MULTIPLE WIRELESS NETWORK GROUPS

Abstract

Exchanging information between multiple wireless network groups is implemented by a wireless channel with a wide transmission range and a wireless channel with a narrow transmission range so as to predetermine data transmission schedule of each node of the multiple wireless network groups. Hence, a drawback of the prior art, that is, reduced transmission efficiency and increased power consumption due to collisions between packets of the multiple wireless network groups, is overcome.
