System and method for single radio multi-device communication
View Patent ↗Aspects of the present disclosure involve a system and method for communicating with multiple devices using a single radio. In one embodiment, a wearable device is configured to use a single radio for near-field and far-field communications. In another embodiment, the wearable device is configured to include an adaptable radio filter that enables the near-field and far-field transmission. The wearable device may further include an adaptable radio IC whose physical layer parameters are adjusted based in part of the transmission mode of a received signal.
1. A method, comprising:
configuring a first device for receiving a signal to establish
a radio link with a second device in response to the signal received wherein the second device communicates using one of a standard communication protocol or a proprietary spectrum;
configuring the first device to analyze the signal received over the radio link to determine a connection type and an associated channel bandwidth;
configuring the first device to dynamically adapt a programmable channel filter in the first device at least based in part on the associated channel bandwidth and the connection type, wherein the adapting of the programmable channel filter comprises forming a channel bandwidth of the programmable channel filter to a wide bandwidth, and adjusting the programmable channel filter to a narrow bandwidth in response to determining the connection type of the proprietary spectrum; and
processing the signal received at the first device.
2. The method of claim 1 , wherein the received signal is filtered by the adapted programmable channel filter.
3. The method of claim 1 , further comprising:
configuring the first device to dynamically adapt the channel bandwidth of the programmable channel filter back to the wide bandwidth.
4. The method of claim 1 , including configuring the first device to adjust the channel bandwidth to approximately 100-200 KHz for the narrow bandwidth and to form the channel bandwidth to approximately 2 MHz for the wide bandwidth.
5. The method of claim 1 , wherein the signal received is a far-field transmission from the second device.
6. The method of claim 1 , wherein the signal received is a near-field transmission from the second device.
7. The method of claim 6 , wherein a channel bandwidth of the second device is adapted during the near-field transmission.
8. The method of claim 1 , wherein the device is a hearing aid.
9. A system, comprising:
at least one radio, the at least one radio configured to:
receive a signal to establish
a radio link with a device in response to the signal received wherein the device communicates using one of a standard communication protocol or a proprietary spectrum;
analyze the signal received over the radio link to determine a connection type and associated channel bandwidth;
a filter adaptation module, the filter adaptation module configured to:
dynamically adapt a programmable channel filter at least based in part on the associated channel bandwidth and the connection type, wherein the adapting of the programmable channel filter comprises forming a channel bandwidth of the programmable channel filter to a narrow bandwidth in response to determining the connection type of the proprietary spectrum; and
a processor, the processor configured to:
process the signal received.
10. The system of claim 9 , wherein the received signal is filtered by the adapted programmable channel filter.
11. The system of claim 9 , wherein the channel bandwidth of the programmable channel filter is a wide bandwidth before the signal is analyzed.
12. The system of claim 9 , further comprising:
the filter adaptation module configured to:
adapt the programmable channel filter from the narrow bandwidth to a wide bandwidth.
13. The system of claim 9 , wherein the signal received uses a near-field transmission.
14. The system of claim 13 , wherein a channel bandwidth of the device is adapted during the near-field transmission.
15. The system of claim 13 , wherein the near-field transmission is over a proprietary frequency.
16. The system of claim 9 , wherein the system is a hearing aid.
