SYSTEM AND METHOD OF CONTROLLING TRANSMIT POWER FOR MOBILE WIRELESS DEVICES WITH MULTI-MODE OPERATION OF ANTENNA
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.
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.
