WIRELESS TRANSMITTER INITIATED COMMUNICATION METHODS
First Claim
1. A method of wireless communication comprising:
- providing a system of peer communication devices configured for sending and receiving signals wirelessly;
the peer communication devices following a first channel succession defining a number of communications channels to which the communication devices are tuned at particular times;
a first peer communication device generating a request to send data to a second peer communication device using a first channel in the channel succession;
the second peer communication device receiving the request to send data from the first peer communication device and generating a clear to send data message to the first peer communication device using the first channel;
the first and second peer communication devices then following a second channel succession to perform data transfer between the first peer communication device and the second peer communication device; and
when a new device is added to the system, the new device entering into a discovery mode wherein the new device learns the system timing and the state of the first channel succession.

Abstract
Wireless communication systems using transmitter initiated communications methods. Several devices in the system listen by following a common frequency hopping sequence. When communication is desired, a transmitting device sends a request to send signal to an addressee; if available, the addressee sends a clear to send signal, and the transmitting device and the addressee then perform communications using a separate frequency hopping sequence. Methods for adding new devices are also included. In an example, a new device uses a discovery frequency hopping sequence to ping a number of frequencies until the common frequency hopping sequence is discovered. In another example, a new device listens on a single frequency forming part of the common frequency hopping sequence until the common frequency hopping sequence overlaps the single frequency.

18. A method of wireless communication for a communication system comprising a number of peer devices configured to generate requests to send data when data is ready to send, the method comprising:
-
the devices in the system following a first channel succession when not transmitting data;
when a first device is prepared to send data, the device addressing a request to send data to a second device;
the second device sending a clear to send data message to the first device; and
the first and second devices following a second channel succession when transmitting data, the second channel succession being different from the first channel succession.

19. A method of wireless communication for a communication system comprising a number of peer devices configured to generate requests to send data when data is ready to send, wherein new devices can be added to the system, the method comprising:
-
when a new device is added to the system, the new device defaulting to a discovery process, the discovery process comprising listening on a single channel chosen from a number of channels included in the first channel succession until either the new device times out, or until a message is generated by one of the existing peer devices in the single channel; and
once the message is generated on the single channel, the new device time synchronizing with the other peer devices.

20. A method of wireless communication for a communication system comprising a number of peer devices configured to generate requests to send data when data is ready to send, wherein new devices can be added to the system, the method comprising:
when a new device is added to the system, the new device defaulting to a discovery process, the discovery process comprising following a second channel succession covering channels covered by the first channel succession until either the new device times out, or until a message is generated by one of the existing peer devices and captured by the new device. - View Dependent Claims (21, 22, 23)
