1. A radio-capable device, comprising:
- a data collection unit for collecting data, and having a normal operating mode, in which it is enabled for collecting data, and a low-power mode;
a radio communication unit for transmitting over a radio channel data collected by the data collection unit; and
a radio channel sensor coupled to the radio communication unit for sensing at least one physical characteristic of the radio channel, and arranged to cause the data collection unit to enter the normal operating mode if the physical characteristic meets a pre-set threshold.

15. A radio-capable device, comprising:
-
a data collection unit for collecting data, and having a normal operating mode in which it is enabled for collecting data, and a low-power mode; a radio communication unit for transmitting over a radio channel data collected by the data collection unit; and a radio channel sensor coupled to the radio communication unit for sensing a change in at least one physical characteristic of the radio channel that is indicative of use of the device by a user, and arranged to cause the data collection unit to enter the normal operating mode from the low-power mode upon sensing of said change. - View Dependent Claims (16, 17, 18, 19)

20. A wireless device having a normal operational mode and a low-power standby mode, comprising:
-
a transceiver capable of transmitting and receiving signals over a wireless communication channel; and a wireless communication channel sensor coupled to the transceiver for sensing a change in at least one physical characteristic of signals received over the wireless channel that is indicative of use of the device by a user, and arranged to cause the wireless device to enter the normal operational mode from the low-power mode upon sensing of said change.
