Abstract: The present invention relates to an arrangement for point-to-point transmission over links between first and second link (end) terminals in a system implementing time division duplex (TDD) and wherein information is sent over the links in frames divided into time slots. It is adapted to determine the lengths of the frames on a per link basis using one or more link parameters, the frame length hence being variable.

Abstract: A method and system of merging signals feeding the antenna elements by using a combiner network and to create an antenna reference point representing the signal representation in the air. This merged signal will be easily accessed for measurement purposes. An additional signal combiner connected to the output terminals of the distributed power amplifier modules of the active antenna creates a measured virtual antenna reference point which may be utilized in testing and typing active antennas having distributed electronics for a certification according to standards for GSM, PDC and DCS. The corresponding method for measuring active receive antennas is also disclosed. Also discloses a measurement system for application of the new method of obtaining a virtual transmit or receive antenna.

Abstract: The present invention discloses an antenna device and system design forming a modular common antenna surface having various surface portions for transmission and reception as well as integrated transmission and reception within the same common antenna surface, the various surface portions either forming passive or active arrays for transmission or reception. Additionally superimposed surface portions of the modular common antenna surface constitute individual transmit and receive array portions, respectively, sharing the total aperture, the modular common antenna surface producing at least one polarization plane for transmission and generally two orthogonal polarization planes for reception to achieve polarization diversity for the reception. Further the antenna surface of the device and system according to the invention generally form a microstrip module array containing a number of radiation element for transmission and/or reception, and consist of one or several columns of individual element forming the antenna aperture, the column and/or columns additionally in the preferred arrangement having integrated power amplifiers and/or low noise amplifiers (LNA:s), respectively.
