- 1. A terminal (20) of a cellular network, which terminal has a transmitter (23), a receiver (22), a control unit (24) and an user interface (26), as well as means for utilizing radio frequency WLAN properties, wherein the activity state of said radio frequency WLAN utilization in the terminal is arranged to control the level of the WLAN power save mode wherein active WLAN utilization is arranged to decrease said level of the power save mode and/or less active WLAN utilization is arranged to increase said level of the power save mode.
- 9. A device arrangement comprising a first device (30) of a cellular network, which device has a transmitter (33), a receiver (32) and a control unit (34), as well as means for utilizing Bluetooth properties, and a second device (38) having an user interface (36) and means for utilizing Bluetooth properties arranged to communicate with the first device (30) by Bluetooth, wherein the activity state of the user interface utilization in the second device is arranged to control the level of the Bluetooth power save mode wherein active user interface utilization is arranged to decrease said level of the power save mode and/or less active user interface utilization is arranged to increase said level of the power save mode.
- 16. A device of cellular network comprising means for utilizing Bluetooth properties arranged to communicate by Bluetooth with a second device comprising means for utilizing Bluetooth properties and an user interface, wherein the activity state of the user interface utilization in the second device is arranged to control the level of the Bluetooth power save mode, wherein active user interface utilization is arranged to decrease said level of the power save mode and/or less active user interface utilization is arranged to increase said level of the power save mode.
- 23. A device comprising an user interface and means for utilizing Bluetooth properties arranged to communicate by Bluetooth with a terminal of cellular network comprising means for utilizing Bluetooth properties, wherein the activity state of the user interface utilization in said device is arranged to control the level of the Bluetooth power save mode wherein active user interface utilization is arranged to decrease said level of the power save mode and/or less active user interface utilization is arranged to increase said level of the power save mode.
- 29. A method for controlling the power saving properties of short range wireless radio frequency communication between a first device and a second device in order to increase the operative life of the batteries in any of the devices wherein at least one of the devices utilizes also cellular phone technology, wherein the activity state of the utilization of said short range radio frequency wireless communication in one of the devices defines the level of the power save mode of said short range wireless communication wherein active utilization of said short range wireless communication will decrease said level of the power save mode and/or less active utilization of said short range wireless communication will increase said level of the power save mode.
