Abstract

A wireless communication system includes a plurality of headsets, each embodying a wireless transceiver, and wherein communication can be established between the headsets via the wireless transceivers over a network in which the headsets act as nodes.

Claims

1. A wireless communication system, comprising:

a plurality of headsets, each incorporating a wireless communications module comprising;

a power supply, a microphone, a speaker, a wireless transceiver, a memory, and a processor responsive to instructions stored in the memory to control operation of the wireless communications module to establish a peer-to-peer mesh communication network,

wherein each headset can communicate directly with any other headset within range without requiring connection to a central controller and with the wireless communications modules incorporated in the headsets acting as nodes in the network, and wherein the wireless communication module of each headset is configured to serve as a repeater to retransmit to rely received packet addressed to another headset in the network provided that the received packet has not already been retransmitted more than a certain number of times, and wherein the wireless communication module of each headset is further configured to;

search a set of preconfigured channels for an operating channel of an existing communication network on power-up and if an existing communication network is found, join the existing communication network, and otherwise form a new communication network on a selected one of said preconfigured channels; and

broadcast data messages to other members of the communication network containing link status and network knowledge information; and

wherein one of said headsets in said communication network is configured to take on the role of network manager coordinating modem or RF changes based on said network knowledge information; and

wherein at least one of the plurality of headsets forming a network is configured to set a timer, and upon expiry of the timer or another headset joining the network, scan all said preconfigured channels to look for another network to merge with said formed network.

2. A wireless communication system as claimed in claim 1, wherein said packet network is an IP network.

3. A wireless communication system as claimed in claim 2, wherein said network is based on an IEEE 802.15 air interface.

4. A wireless communication system as claimed in claim 1, further comprising an interface module for connection to an external radio communication system, and wherein said interface module includes a transceiver for establishing wireless communication with said headsets, wherein said interface module can be incorporated as part of the network including said headsets.

5. A wireless communication system as claimed in claim 1, wherein the electronic components of each wireless communication module are mounted on a printed circuit board conforming to the shape of an earpiece of the headset.

6. A wireless communication system as claimed in claim 1, further comprising a management interface for connection to, and for controlling operation of, said wireless communication modules.

7. A wireless communication system as claimed in claim 1, further comprising at least one stand-alone wireless controller including at least a push-to-talk button for remotely controlling operation of one of said wireless communications modules.

8. A wireless communication system as claimed in claim 7, wherein the stand-alone wireless controller comprises a wireless transceiver, a memory, and a processor responsive to instructions stored in the memory, to control operation of the wireless controller so that it acts as a node in the network.

9. A wireless communication system as claimed in claim 8, wherein the wireless controller includes a data interface.

10. A wireless communication system as claimed in claim 1, further comprising an active noise cancelation subsystem to reduce ambient noise.

11. A wireless communication system as claimed in claim 1, further comprising a stand-alone wireless controller, the stand-alone wireless controller comprising a wireless transceiver, a memory, and a processor responsive to instructions stored in the memory to control operation of the wireless controller, and a push-to-talk button for remotely controlling operation of a local said headset, and wherein the wireless controller is configured to act as a node in the network such that the wireless controller communicates with the wireless communications modules of other headsets in the network.

12. A headset for incorporation into a wireless communication system enabling communication among a group of users, incorporating a wireless communications module comprising a power source, a microphone, a speaker, a wireless transceiver, a memory, and a processor responsive to instructions stored in the memory to control operation of the wireless communications module to establish a peer-to-peer mesh communication network with like wireless communication modules wherein each headset can communicate directly with any other headset within range without requiring connection to a central controller, and wherein the wireless communication modules act as nodes in the network, and wherein the wireless communication module is configured to serve as a repeater to retransmit any received packet addressed to another headset in the network provided that the received packet has not already been retransmitted more than a certain number of times, and wherein the wireless communication module is further configured to:

search a set of preconfigured channels for an operating channel of an existing communication network on power-up and if an existing communication network is found, join the existing communication network, and otherwise form a new communication network on a selected one of said preconfigured channels; and

broadcast data messages to other members of the communication network containing link status and network knowledge information to permit one of said headsets in the communication network to take on the role of network manager coordinating modem or RF changes based on said network knowledge information contained in said data messages, and

when the headset acts as a network former to set a timer, and upon expiry of the timer or another headset joining the network, scan all said preconfigured channels to look for another network to merge with said formed network.

13. A headset as claimed in claim 12, wherein said packet network is an IP network.

14. A headset as claimed in claim 13, wherein said network is based on an IEEE 802.15 air interface.

15. A headset as claimed in claim 12, wherein the wireless communication module is configured to serve as a repeater to forward a received signal to the wireless communication module of another headset, thereby extending the effective range of other wireless communication modules in the network.

16. A headset as claimed in claim 12, wherein the electronic components of each wireless communication module are mounted on a printed circuit board conforming to the shape of an earpiece of the headset.

17. A headset as claimed in claim 12, further comprising at least one stand-alone wireless controller including at least a push-to-talk button for remotely controlling operation of one of said wireless communications modules.

18. A headset as claimed in claim 12, comprising a user interface residing on the headset itself.

19. A headset as claimed in claim 17, comprising a user interface residing on a linked wireless controller.

20. A headset as claimed in claim 12, further comprising user interface controls on the headset, and user interface controls on a linked wireless controller configurable to be mirrored to those on the headset.

21. A headset as claimed in claim 12, further comprising user interface controls on the headset, and user interface controls on a linked wireless controller that are configurable to be different to allow for extended functionality for the operator.
