摘要:
An antenna swapping method may include tuning respective signals provided to first and second antennas in a portable electronic device to at least one frequency band. The method may also include connecting the first antenna to an uplink signal path that is for transmissions through the first and second antennas, and performing impedance matching for the first antenna. The method may further include comparing a real-time performance characteristic of the first antenna with a real-time performance characteristic of the second antenna. The method may additionally include, responsive to determining that the second antenna has a stronger real-time performance characteristic than the first antenna while the first antenna is connected to the uplink signal path, swapping from the first antenna to the second antenna by connecting the second antenna to the uplink signal path and disconnecting the first antenna from the uplink signal path, and performing impedance matching for the second antenna.

The present invention relates to an antenna arrangement for a portable communication device as well as to a portable communication device comprising such an antenna arrangement. The antenna arrangement includes a ground plane, a first radiating electrical antenna element provided in a plane arranged at a distance above and parallel with at least a part of the ground plane, where the first radiating electrical antenna element is dimensioned for resonating at least at one frequency, and a second radiating magnetic antenna element provided in the ground plane below the first antenna element and being dimensioned for resonating at the same frequency as the first radiating antenna element.
摘要:
The present invention concerns devices and methods for control of data transfer in a personal area network. The data transfer being performed by body coupled communication (BCC) and short-range wireless communication between a first portable electronic communication device (10) and a second portable electronic communication device (20, 30). The devices being adapted to be in close proximity to a body of a user and the first portable electronic communication device (10) is configured to initiate and perform execution of predefined actions by means of the method to cooperate with the second portable electronic communication device (20, 30) in a system/personal area network.
摘要:
The present invention relates to a method and a mobile communication terminal comprising a communication interface having an antenna arrangement, an arrangement for providing a geographical position of the terminal, a memory and a controller. The controller is configured to adjust transmission parameters of said antenna arrangement with respect to a geographical position of the mobile communication terminal with respect to a geographical position data received from said arrangement for providing a geographical position of the mobile communication terminal.
摘要:
Antenna swapping methods for a wireless electronic device may include refraining from swapping antennas of the wireless electronic device for wireless communication with a network other than during a time period that is received at the wireless electronic device from the network. Related systems and devices are also described.

The present invention concerns wearable electronic communication devices (100) for control of data transfer in a personal area network. The wearable device is adapted for Body Coupled Communication in close proximity to a person's body. The wearable device comprises an antenna adapted for Body Coupled Communication and a capacitance sensor indicating that the wearable device is in close proximity to the body of the person or even in contact with the body or not. The invention also concerns a portable electronic communication device comprising the inventive wearable device for cooperation with at least a second portable electronic communication device in a personal area network.
摘要:
A calendar system incorporates information from publication sources for display as information events on a calendar of the calendar system. A respective user of the calendar system may subscribe to an identified publication source that is internal or external to the calendar system. The calendar system determines whether data from the identified publication source conforms with a predefined calendar data exchange format. If data from the identified publication source conforms with the predefined calendar data exchange format, the calendar system may import data from the publication source and transmit the data (including data for at least one information event) to at least one client for rendering of the calendar system. If data from the identified publication source fails to conform with the predefined calendar data exchange format, the calendar system may re-format the data to conform to a calendar data exchange format that is compatible with the calendar system.
摘要:
A radio telephone for use in wireless telecommunication has a transmitter/receiver unit (4), a control unit (5), a first antenna (1), the properties of which are optimized for use in stand-by mode, and a second antenna (2), the properties of which are optimized for use during ongoing calls, said second antenna being electrically engageable and disengageable with the transmitter/receiver unit. The radio telephone further has an antenna switch (3), which is arranged to operatively connect the transmitter/receiver unit (4) to either the first antenna (1) or the second antenna (2), said antenna switch supplying the control unit (5) with control signals (7) in response to at least the electrical engagement status of the second antenna. The control unit prevents ingoing as well as outgoing calls from being established, as long as the second antenna according to said control signals is indicated to be electrically disengaged.
