Abstract
A method and system for establishing a non-frequency-hopping connection link between a slave device with another slave device 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 slave devices are capable of being carried out in a frequency-hopping fashion. The non-frequency-hopping connection link can be established after the channel conditions, including the carrier power of the channel and the interference and noise levels adversely affecting the connection link, are measured.

20. A method of communication between a plurality of network devices in a communication network, the communication devices including a first network device and a second network device, said method comprising:
-
establishing a non-frequency-hopping connection link between the first network device and the second network device if said non-frequency-hopping connection link is available; and
establishing or maintaining the frequency-hopping connection link between the first network device and the second network device, if said non-frequency-hopping connection link is unavailable. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A system for adaptive allocation of communications channels between a first network device and a second network device in a communications network, said system comprising:
-
a first mechanism for determining whether a non-frequency-hopping connection link between the first network device and the second network device is available; and
a second mechanism for establishing the non-frequency hopping connection link between the first network device and the second network device if the non-frequency-hopping connection link is available, and maintaining or establishing the frequency hopping connection link between the first network device and the second network device if the non-frequency-hopping connection link is unavailable. - View Dependent Claims (35, 36, 37, 38, 39, 40)

41. A network device in a communications network, comprising:
-
a linking mechanism for establishing a frequency hopping connection link between the network device and a different network device in the communications network; and
a request mechanism for requesting a non-frequency hopping connection link between the network device and said different network device;
whereinthe linking mechanism is configured to establish said non-frequency hopping connection link if said non-frequency hopping connection link is available, and to maintain the frequency hopping connection link if said non-frequency hopping connection link is unavailable. - View Dependent Claims (42, 43, 44)
