Abstract: A radio transceiver comprises one or more hardware resources, e.g. a processor; memory; a peripheral device; an algorithmic hardware accelerator; and/or a radio frequency component. A cellular communication radio is operable in an active mode in which it has access to the one or more hardware resources for transmitting and/or receiving cellular communication signals, and an inactive mode in which it does not. A global navigation satellite systems radio, arranged to use the one or more hardware resources to receive positioning signals, has access to the one or more hardware resources only when the cellular communication radio is operated in the inactive mode.

Abstract: A wireless communication arrangement (100a) with multiple antennas for a vehicle includes a first printed circuit board (110) having a modem unit (111) and a radiating antenna element (113); a second printed circuit board (120) having a radiating antenna element (123); an interface unit (112) disposed on the first printed circuit board (110) and/or the second printed circuit board (120); and a main bendable portion (130) bendably and electrically connecting the first printed circuit board (110) and the second primed circuit board (120) to each other. The first printed circuit board (110) and the second printed circuit board (120) are mountable on an outer surface of a vehicle in non-horizontal orientation with respect to said outer surface, with the first printed circuit board (110) and the second printed circuit board (120) forming a convex like shape in a horizontal direction via bending of the main bendable portion (130).

Abstract: In relation to wireless communication, a communications apparatus suitable for installation into a vehicle provides a user-driven communication capability in a vehicle communications system. The apparatus includes means providing a wide-area communication capability, at least one antenna interface for conveying signals to and/or from at least one antenna providing wide-area communication, at least one power input configured to receive operating power for the apparatus from a vehicle and at least one digital communication interface for providing connectivity to a master unit of the vehicle.

Abstract: An apparatus and method for sharing antenna allow an antenna to be shared simultaneously by two modems and a reduction in antenna count. The apparatus includes a first modem and a second modem and a switch system is arranged to selectively connect one of the first and second modems to a first antenna and selectively connect one of the first and second modems to a second antenna. A pass through output is associated with the first modem and arranged to selectively output at least a portion of a received signal to the second modem. The pass through output allows some or all of the received signal to be passed on to the second modem, so both modems can share same antenna at the same time.

Abstract: Equipment for transmitting a signal, the equipment comprising an antenna array (600-606) for providing three or more radiation antenna patterns. The equipment is arranged to transmit a primary common pilot signal with at most two radiation patterns and a secondary common pilot signal with at least one radiation pattern. The equipment comprises controllers (622a-622d) for adjusting the power ratio between the primary and the secondary common pilot signal and the total power of the primary and the secondary common pilot signals, and controllers (614a-614d) for adjusting the transmit power of the dedicated pilot signal, such that the power levels of the dedicated pilot signals transmitted with the same radiation patterns as the secondary common pilot signal are relatively higher than the power levels of the dedicated pilot signals transmitted with the same radiation patterns as the primary common pilots.

Abstract: A method for transmitting from a multi-antenna station and a multi-antenna station is provided. The station is provided with a reference antenna and a diversity antenna. During the operation of the method, one of the antennae is selected to be stronger in the event of power unbalance between the diversity and reference antennae. Greater transmission power is assigned for the diversity antenna than the reference antenna when the diversity antenna is only phase adjusted. Greater transmission power is assigned for the reference antenna than the diversity antenna when the reference antenna is amplitude adjusted.

Abstract: The present invention presents a method and apparatus for phase hopping and space-time coding signals for transmission on multiple antennas. The method and apparatus provides expansion of a N×N′ space time block code to a M×M′ space time block code, where M>N, by using phase hopping on the symbols within the N×N′ space time block code to allow transmission of the space time block code on a number of diversity antennas greater than N′. A result of M antenna diversity may be achieved for M transmit antennas.
