Method and apparatus for a radio communication system
First Claim
1. A radio communication system operating over a sequence of communication channels, comprising:
- a first communication device having means for communicating over the sequence of communication channels using channel hopping, and having an operating communication channel; and
a second communication device, comprising;
means for scanning among the sequence of communication channels to determine the operating communication channel and channel hopping parameters of the first communication device;
means for communicating over the sequence of communication channels using channel hopping synchronized with the channel hopping of the first communication device; and
means for selecting an operating communication channel for the second communication device different from the operating communication channel of the first communication device when both communication devices operate simultaneously.

Abstract
A radio communication system (10) operates over a sequence of communication channels using a synchronized channel hopping protocol. A first communication device (16) is provided which is capable of communicating over the sequence of communication channels using channel hopping, and which has an operating communication channel. A second communication device (13) is provided, which is capable of determining the operating communication channel and channel hopping parameters of the first communication device (16). The second communication device (13) can communicate over the sequence of communication channels using channel hopping synchronized with the channel hopping of the first communication device (16), while selecting an operating communication channel different from the operating communication channel of the first communication device (16) when both communication devices (13, 16) operate simultaneously.

7. A method of operating a radio communication system using a channel hopping protocol, the radio communication system having a first transceiver channel hopping among a sequence of communication channels and having an operating communication channel, the method comprising the steps of:
-
providing a second transceiver having means for channel hopping among the sequence of communication channels; scanning among the sequence of communication channels to locate the operating communication channel of the first transceiver; and synchronizing channel hopping of the second transceiver with the channel hopping of the first transceiver such that the second transceiver has an operating communication channel different from the operating communication channel of the first transceiver when both transceivers are operating simultaneously. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

20. In a radio communication system using a channel hopping protocol, and having a first transceiver and a second transceiver, the first transceiver channel hopping among a sequence of communication channels and having an operating communication channel, the second transceiver being capable of channel hopping among the sequence of communication channels, a method at the second transceiver comprising the steps of:
-
scanning among the sequence of communication channels to locate the operating communication channel of the first transceiver; synchronizing channel hopping of the second transceiver with the channel hopping of the first transceiver; selecting a reservation channel from among the sequence of communication channels; reserving a communication slot by transmitting on the reservation channel in an extended range mode; and operating within the communication slot such that the second transceiver has an operating communication channel different from the operating communication channel of the first transceiver when both transceivers are operating simultaneously.
