Abstract

Example embodiments of the present disclosure generally relate to automatic wireless mode switching in wireless communication devices and systems, and methods of automatic wireless mode switching. In one example embodiment, a wireless communication device generally includes a wireless communication interface configured to transmit data to a remote device via wireless communication, and a controller configured to control a mode of operation of the wireless communication device and to automatically switch the mode of operation of the wireless communication device between at least a first mode of operation and a second mode of operation. The first mode of operation is one of a client mode of operation, an access point mode of operation, an ad hoc mode of operation, a dual mode operation and a tri-mode operation. The second mode of operation is one of a dual mode operation and a tri-mode operation.

Claims

1. A wireless communication device comprising:

a wireless communication interface configured to transmit data to a remote device via wireless communication and to receive data from the remote device via wireless communication; and

a controller configured to control a mode of operation of the wireless communication device and to automatically switch the mode of operation of the wireless communication device between at least a first mode of operation and a second mode of operation;

wherein;

the first mode of operation is one of a client mode of operation, an access point mode of operation, an ad hoc mode of operation, a dual mode operation and a tri-mode operation;

the second mode of operation is one of a dual mode operation and a tri-mode operation; and

the wireless communication interface is configured to join a pre-existing wireless network by configuring the wireless communication interface to have a same network identification, authentication type, and authentication credentials as the pre-existing wireless network to act as an access point to a user device, while simultaneously operating in a client mode to connect to the same pre-existing wireless network.

2. The wireless communication device of claim 1, wherein the controller is configured to switch the mode of operation of the wireless device based on at least one of an external electrical input, an input from another device on a network the wireless communication interface is configured to connect to, an input from a cloud based service, an input from another device connected via a Bluetooth wireless connection, an input from a device connected via a wide area network connection, a location of the wireless communication device, and a quality of service and wireless performance of one or more networks the wireless communication interface is configured to connect to.

3. The wireless communication device of claim 1, wherein the controller is configured to facilitate another device to roam between a wireless connection to the wireless communication device and a wireless connection to an infrastructure network.

4. The wireless communication device of claim 3, wherein the controller is configured to facilitate another device to roam by reducing a transmit power of the wireless communication interface.

5. The wireless communication device of claim 1, wherein the controller is configured to switch the mode of operation between at least three modes of operation.

6. The wireless communication device of claim 5, wherein the controller is configured to switch the mode of operation between at least four modes of operation.

7. The wireless communication device of claim 6, wherein the controller is configured to switch the mode of operation between at least five modes of operation.

8. A vehicle including an embedded wireless communication device of claim 1.

9. A wireless communication device comprising:

a wireless communication interface configured to transmit data to a remote device via wireless communication and to receive data from the remote device via wireless communication; and

a controller configured to control a mode of operation of the wireless communication device and to automatically switch the mode of operation of the wireless communication device between at least a first mode of operation and a second mode of operation;

wherein;

the first mode of operation is one of a client mode of operation, an access point mode of operation, an ad hoc mode of operation, a dual mode operation and a tri-mode operation;

the second mode of operation is one of a client mode of operation, an access point mode of operation, an ad hoc mode of operation, a dual mode operation and a tri-mode operation;

the controller is configured to switch the mode of operation of the wireless device based on at least one of an external electrical input, an input from another device on a network the wireless communication interface is configured to connect to, an input from a cloud based service, an input from another device connected via a Bluetooth wireless connection, an input from a device connected via a wide area network connection, a location of the wireless communication device, and a quality of service and wireless performance of one or more networks the wireless communication interface is configured to connect to; and

the controller is configured to facilitate a client device to roam between a wireless connection to the wireless communication device and a wireless connection to an access point of an infrastructure network by slowly reducing a transmit power of the wireless communication interface until the client device roams to the access point of the infrastructure network.

10. The wireless communication device of claim 9, wherein the controller is configured to switch the mode of operation based on an external electrical input.

11. The wireless communication device of claim 10, wherein the external electrical input is at least one of on-board diagnostics data from a vehicle controller area network bus and general-purpose input/output data from another device electrically wired to the wireless communication device.

12. The wireless communication device of claim 9, wherein the controller is configured to switch the mode of operation based on at least one of an input from another device on the network the wireless communication interface is configured to connect to and a cloud based service.

17. The wireless communication interface of claim 9, wherein the wireless communication interface is configured to join a pre-existing wireless network by configuring the wireless communication interface to have a same network identification, authentication type, and authentication credentials as the pre-existing wireless network to act as an access point to a user device, while simultaneously operating in a client mode to connect to the same pre-existing wireless network.

18. The method of claim 9, further comprising joining a pre-existing wireless network by configuring the wireless communication interface to have a same network identification, authentication type, and authentication credentials as the pre-existing wireless network to act as an access point to a user device, while simultaneously operating in a client mode to connect to the same pre-existing wireless network.

19. A method of controlling operation of a wireless communication device, the wireless communication device having a wireless communication interface configured to transmit data to a remote device via wireless communication and to receive data from the remote device via wireless communication and a controller configured to control a mode of operation of the wireless communication device, the method comprising:
