Abstract

A method and system for establishing a connection link between a master device and a plurality of slave devices in a communications network having a plurality of frequency channels within a radio frequency band known as the unlicensed ISM band, wherein the connection links between the master device and the slave devices are capable of being carried out in a frequency-hopping fashion. The method comprises the steps of sending a link request to the master device requesting establishment of a non-frequency-hopping connection link between the master device and a slave device; establishing the non-frequency-hopping connection link as requested if the master device is able to select a communication channel for such a connection link; and establishing or maintaining the connection link in the frequency-hopping fashion if the master device is unable to select such a communication channel. In order to establish the non-frequency-hopping connection link, channel conditions including the carrier power of the channel and the interference and noise levels adversely affecting the connection link are measured.
