Abstract

A method is performed by a wireless communication device. The device uses a first transmission rate upon initiation of a wireless communication. During the wireless communication, the device detects that the device has entered a predetermined use mode. In response, the device automatically switches to a second transmission rate different than the first transmission rate.

Claims

1. A method performed by a wireless communication device, comprising:

using a first transmission rate upon initiation of a wireless communication;

during the wireless communication, detecting that the wireless communication device has entered a predetermined use mode; and

in response to detecting that the wireless communication device has entered the predetermined use mode, automatically switching to a second transmission rate different than the first transmission rate.

2. The method of claim 1 wherein the predetermined use mode is selected from in-holster mode in which the device is secured within a device holster, in-hand mode in which the device is held in a user'"'"'s hand, by-head mode in which the device is positioned close to a head, in-cradle mode in which the device is in a device cradle, antenna-drawn mode in which an antenna of the device is drawn outwards, external-antenna mode in which an external antenna is attached to the device, headset mode in which a headset or earpiece is connected to the device, keyboard-activity mode in which there is activity on a keyboard of the device, and speakerphone mode.

3. The method of claim 2 wherein the predetermined use mode is the speakerphone mode.

4. The method of claim 2 wherein the predetermined use mode is selected from the antenna-drawn mode and the external-antenna mode.

5. The method of claim 2 wherein the predetermined use mode is the headset mode.

6. The method of claim 2 wherein the wireless communication device is a cellular telephone.

7. The method of claim 2 further comprising:

using a first signal encoding upon initiation of a wireless communication and automatically switching to a second, different, signal encoding in response to detecting that the wireless communication device has entered the predetermined use mode.

8. The method of claim 2 further comprising:

using a first modulation method upon initiation of the wireless communication and automatically switching to a second, different, modulation method in response to detecting that the wireless communication device has entered the predetermined use mode.

9. A method performed by a wireless communication device having an antenna, comprising:

using a first antenna gain of the antenna upon initiation of a wireless communication;

during the wireless communication, detecting that the wireless communication device has entered a predetermined use mode; and

in response to detecting that the wireless communication device has entered the predetermined use mode, automatically switching to a second antenna gain of the antenna different than the first antenna gain.

10. The method of claim 9 wherein the predetermined use mode is selected from in-holster mode in which the device is secured within a device holster, in-hand mode in which the device is held in a user'"'"'s hand, by-head mode in which the device is positioned close to a head, in-cradle mode in which the device is in a device cradle, antenna-drawn mode in which an antenna of the device is drawn outwards, external-antenna mode in which an external antenna is attached to the device, headset mode in which a headset or earpiece is connected to the device, keyboard-activity mode in which there is activity on a keyboard of the device, and speakerphone mode.

11. The method of claim 10 wherein the predetermined use mode is the speakerphone mode.

12. The method of claim 10 wherein the predetermined use mode is selected from the antenna drawn mode and the external-antenna mode.

13. The method of claim 10 wherein the predetermined use mode is the headset mode.

14. The method of claim 10 wherein the wireless communication device is a cellular telephone.

15. A method performed by a wireless communication device having an antenna, comprising:

using a first radiating pattern of the antenna upon initiation of a wireless communication;

during the wireless communication, detecting that the wireless communication device has entered a predetermined use mode; and

in response to detecting that the wireless communication device has entered the predetermined use mode, automatically switching to a second radiating pattern of the antenna different than the first radiating pattern.

16. The method of claim 15 wherein the predetermined use mode is selected from in-holster mode in which the device is secured within a device holster, in-hand mode in which the device is held in a user'"'"'s hand, by-head mode in which the device is positioned close to a head, in-cradle mode in which the device is in a device cradle, antenna-drawn mode in which an antenna of the device is drawn outwards, external-antenna mode in which an external antenna is attached to the device, headset mode in which a headset or earpiece is connected to the device, keyboard-activity mode in which there is activity on a keyboard of the device, and speakerphone mode.

17. The method of claim 16 wherein the predetermined use mode is the speakerphone mode.

18. The method of claim 16 wherein the predetermined use mode is selected from the antenna drawn mode and the external-antenna mode.

19. The method of claim 16 wherein the predetermined use mode is the headset mode.

20. The method of claim 16 wherein the wireless communication device is a cellular telephone.
