ADAPTIVE TRANSMISSION CHANNEL ALLOCATION METHOD AND SYSTEM FOR ISM AND UNLICENSED FREQUENCY BANDS

摘要

Connection links are established between a master device and a plurality of slave devices in a network having a plurality of frequency channels within an unlicensed ISM radio band, wherein the connection links are capable of being carried out in a frequency-hopping fashion. A link request is sent to the master device for establishment of a non-frequency-hopping connection link between the master device and a slave device, and the non-frequency-hopping link is established as requested if the master device is able to select a communication channel for such a connection link if measured channel conditions such as carrier power and interference and noise are not adverse. The connection link is maintained or established in frequency-hopping fashion if the master device is unable to select such a communication channel.
