Abstract

Some demonstrative embodiments include devices, systems and/or methods of Bluetooth communication. For example, a Bluetooth communication unit may be capable of detecting a Bluetooth signal via a first antenna, and, upon detecting the Bluetooth signal, to switch to a second antenna, which is shared between the Bluetooth communication unit and an other, different, wireless communication unit, for establishing a Bluetooth communication link.

Claims

1. A device comprising:

a Bluetooth transceiver comprising a receiver, a transmitter, and a controller, the controller configured to connect the receiver to a first antenna, which is dedicated for detecting a Bluetooth signal, and

the controller is configured to, upon detecting said Bluetooth signal via the first antenna, cause said Bluetooth transceiver to switch to communicate via a second antenna, having improved performance compared to the first antenna, to establish a Bluetooth communication link,

said second antenna is shared between said Bluetooth transceiver and an other, a different, non-Bluetooth wireless transceiver,

said controller is configured to, upon detecting said Bluetooth signal, cause a switch component to switch a connection of the second antenna from the other non-Bluetooth wireless transceiver to the Bluetooth transceiver,

wherein said Bluetooth transceiver is to detect said Bluetooth signal via the first antenna when said non-Bluetooth wireless transceiver is communicating via said second antenna.

2. The device of claim 1, wherein said first antenna comprises a stub antenna.

3. The device of claim 1, wherein said Bluetooth transceiver is to detect said Bluetooth signal when said other non-Bluetooth wireless transceiver performs multiple-input-multiple-output (MIMO) communication via a plurality of antennas including said second antenna.

4. The device of claim 1, wherein said Bluetooth signal comprises a Bluetooth advertisement signal.

5. The device of claim 4, wherein said Bluetooth advertisement signal comprises a Bluetooth Low Energy (BLE) advertisement signal.

6. The device of claim 1, wherein said other non-Bluetooth wireless transceiver comprises a Wireless-Fidelity (Wi-Fi) transceiver.

7. A system comprising:

a device including;

a first, Bluetooth, wireless transceiver comprising a receiver, a transmitter and a controller;

a second, non-Bluetooth, wireless transceiver;

a first antenna;

a second antenna shared between said first and second wireless transceivers, the first antenna having degraded functionality compared to the second antenna, said first antenna configured to detect Bluetooth signals, and said second antenna configured to communicate both Bluetooth communication signals as well as non-Bluetooth communication signals,

a switch component configured to switch a connection of the second antenna between the first wireless transceiver and the second wireless transceiver; and

wherein said controller is configured to connect the first wireless transceiver to the first antenna for detecting a Bluetooth signal via said first antenna, and, upon detecting said Bluetooth signal, said controller is to cause the first wireless transceiver to switch to communicate via said second antenna to establish a Bluetooth communication link, said controller is configured to cause the switch component to connect the second antenna to the second wireless transceiver when the first wireless transceiver is to scan for the Bluetooth signal, and, upon detecting said Bluetooth signal, to cause the switch component to switch a connection of the second antenna from the second wireless transceiver to the first wireless transceiver,

wherein said first wireless transceiver is to detect said Bluetooth signal when said second wireless transceiver is communicating via said second antenna.

8. The system of claim 7, wherein said first antenna comprises a stub antenna.

9. The system of claim 7, wherein said second wireless transceiver is configured to perform multiple-input-multiple-output (MIMO) communication via a plurality of antennas including said second antenna.

10. The system of claim 7, wherein said Bluetooth signal comprises a Bluetooth advertisement signal.

11. The system of claim 10, wherein said Bluetooth advertisement signal comprises a Bluetooth Low Energy (BLE) advertisement signal.

12. The system of claim 7, wherein said second wireless transceiver comprises a Wireless-Fidelity (Wi-Fi) transceiver.

13. A method to be performed at a Bluetooth transceiver, the method comprising:

connecting a first, Bluetooth, transceiver to a first antenna dedicated to detect a Bluetooth signal;

causing a switch component to connect a second antenna to a second, non-Bluetooth, transceiver;

while the second transceiver is communicating via the second antenna, scanning a Bluetooth channel for detecting the Bluetooth signal at the first transceiver via the first antenna; and

upon detecting said Bluetooth signal via the first antenna, causing the switch component to switch the second antenna from the second transceiver to said first transceiver, and switching the first transceiver from the first antenna to communicate via the second antenna to establish a Bluetooth communication link.

14. The method of claim 13, wherein said non-Bluetooth communication comprises a multiple-input-multiple-output (MIMO) communication via a plurality of antennas including said second antenna.

15. The method of claim 13, wherein said first antenna comprises a stub antenna.

16. The method of claim 13, wherein said Bluetooth signal comprises a Bluetooth advertisement signal.

17. The method of claim 16, wherein said Bluetooth advertisement signal comprises a Bluetooth Low Energy (BLE) advertisement signal.
