The object of the invention is a method for controlling the power saving properties in a terminal, which utilizes cellular phone technology and short range radio frequency wireless communication features in order to increase the operative life of the batteries, and a terminal utilizing the method. In the method of the invention the activity state of the short range wireless communication utilization in the terminal determines the level of the short range wireless communication power save mode.

Method for saving power in a wireless terminal and a terminal

An inverted-F antenna arrangement comprising a dielectric element structure, a radiating element on the dielectric element, the radiating element having a first end and a second end, a planar ground element, the dielectric element separating the radiating element and the planar ground element, a ground connection element on the dielectric element coupled to the first end of the radiating element for coupling the radiating element to the planar ground element, a feeder element on the dielectric element coupled to the first end of the radiating element for transferring electromagnetic radiation. The radiating element is arranged three-dimensionally on the dielectric element for forming an electrically conductive three-dimensional structure.

Antenna arrangement and method for making the same

The invention relates to a circuit arrangement in association with the RF unit of a wireless terminal, in which circuit arrangement the RF unit and the antenna () of the wireless terminal are fabricated/mounted on the same circuit board () and where the antenna () is connected to the RF unit through at least one signal line (). In the circuit arrangement, the signal line () from the RF unit to the antenna () is electrically connected during the final assembly by means of a jumper () which is fabricated as part of a mechanical component () belonging to the terminal. With the arrangement according to the invention, the RF unit can be tested without interference from the antenna.

RF transceiver arrangement, terminal employing the arrangement, and method for fabricating terminal according to the arrangement

The invention relates to radio terminal equipment arrangement comprising radio terminal equipment and one or more secondary terminal units, the radio terminal equipment being configured to communicate with the one or more secondary terminal units by using wireless low-power radio frequency (LPRF) connections, and to use a predetermined transmitter power class. The radio terminal equipment is further configured to detect a change in a usage environment of the radio terminal equipment; and to change the transmitter power class of the radio terminal equipment based on the changed usage environment of the radio terminal equipment.

Method and radio terminal equipment arrangement for power control, radio terminal equipment and secondary terminal unit

A method of changing an antenna pattern in a radio apparatus and a radio apparatus comprising a planar antenna structure with a first and a second plane are provided. In the solution both planes are arranged to act as a radiator plane and as a ground plane and the apparatus comprises means for interchanging the usages of the planes.
