Abstract

A first device having a transceiver and an antenna operatively connected to the transceiver and a second device having a transceiver and an antenna operatively connected to the transceiver, the first device in operative communication with the second device through a communications linkage separate from the transceiver of the first device and the transceiver of the second device. The first device is adapted to wirelessly communicate with a remote device through the transceiver of the first device. The second device is adapted to wirelessly communicate with the remote device through the transceiver of the second device. The system is configured to evaluate the wireless connection between the first device and the remote device and to evaluate the wireless communication between the second device and the remote device and determine whether the first device or the second device has a better connection.

Claims (38)

a first wearable device having a processor, a radio transceiver, and an antenna operatively connected to the radio transceiver;

a second wearable device having a processor, a radio transceiver and an antenna operatively connected to the radio transceiver, the first wearable device in operative communication with the second wearable device through a communications linkage separate from the radio transceiver of the first wearable device and the radio transceiver of the second wearable device;

wherein the first wearable device is adapted to wirelessly communicate with the mobile phone through the radio transceiver of the first wearable device;

wherein the second wearable device is adapted to wirelessly communicate with the mobile phone through the radio transceiver of the second wearable device;

wherein the first wearable device is configured to:

perform signal measurements of radio signals from the mobile phone to the radio transceiver of the first wearable device;

evaluate a wireless radio connection strength between the first wearable device and the mobile phone;

communicate the wireless radio connection strength between the first wearable device and the mobile phone to the second wearable device using the communications linkage separate from the radio transceiver of the first wearable device and the radio transceiver of the second wearable device;

wherein the second wearable device is configured to:

perform signal measurements of radio signals from the mobile phone to the radio transceiver of the second wearable device;

evaluate a wireless radio connection strength between the second wearable device and the mobile phone;

communicate the wireless radio connection strength between the second wearable device and the mobile phone to the first wearable device using the communications linkage separate from the radio transceiver of the first wearable device and the radio transceiver of the second wearable device;

wherein the system is configured to:

determine whether the first wearable device or the second wearable device has a better connection using the wireless radio connection strength between the first wearable device and the mobile phone and the wireless radio connection strength between the second wearable device and the mobile phone and if the first wearable device has the better connection to use the wireless radio connection between the first wearable device and the mobile phone and if the second wearable device has the better connection to use the wireless radio connection between the second device and the mobile phone;

handover a wireless radio connection with the mobile phone from the second wearable device to the first wearable device to achieve the better connection when the first wearable device has the better connection but a connection between the second wearable device and the mobile phone is being used; handover a wireless radio connection with the mobile phone from the first wearable device to the second wearable device to achieve the better connection when the second wearable device has the better connection but a connection between the first wearable device and the mobile phone is being used to handover the connection from the first wearable device and the mobile phone to the second wearable device;

wherein the transceiver of the first wearable device is a Bluetooth transceiver and wherein the transceiver of the second wearable device is a Bluetooth transceiver;

wherein the first wearable device is configured to receive streaming audio of the wireless connection between the first wearable device and the mobile phone and wherein the second wearable device is configured to receive streaming audio of the wireless connection between the second wearable device and the mobile phone.
