Abstract: A base station includes multiple sector antenna units. Each sector antenna unit has an antenna for receiving a carrier signal associated with an antenna frequency in an available frequency band. The base station is converted between a multiple sector base station configuration and a multi-sector, omni-base station configuration. In a diversity base station implementation, each sector antenna unit receives a diversity signal from a first sector, and the second diversity antenna unit receives a diversity signal from a second different sector. If one sector antenna unit does not perform properly so that one of the sector diversity signals is lost or corrupted, the other sector diversity signal is still useable. The base station may be reconfigured to power-down at least some part of the transmit side without having to power-down some or all of the receive side.

Abstract: An object of the present invention is to provide a mechanism for tamper detection of electronic devices (110) in closed units which is robust and low cost. The object is achieved by a method in an electronic device (110) for detecting if a cover (100) enclosing the electronic device (110) has been opened. The cover (100) comprises an enclosing assembly (250) which is adapted to fasten the cover (100) into a closed position. The electronic (device 110) comprises a non volatile memory (120). The non volatile memory (120) comprises a stored reference signature associated to the enclosing assembly (250) when the cover (100) was fastened into a closed position. The method comprises the following steps: (Creating 1003) a signature associated to the enclosing assembly (250). Comparing (1004) the created signature with the reference signature. Detecting (1007) that the cover 100 has been opened when the comparing (1004) results in a difference.

Abstract: Each transmitter/receiver pair of a radio base station is connected via an antenna bus and radio frequency feeder to antenna near parts equipment such as active antennas, boosters and tower mounted amplifiers. Automatic configuration and calibration of the antenna near parts equipment is accomplished by establishing communication between the base station and each of its connected antenna near part components. Each antenna near part component sends its identification to the base station over the antenna bus at power-on. Furthermore, communications selectively sent over the radio frequency feeder are monitored to determine the connectivity between individual transmitter/receiver pairs of the base station and each antenna near parts equipment. These radio frequency feeder communications are further processed to determine calibration data for configuring each antenna near parts equipment for optimal operation.

Abstract: The present invention relates to methods and or receiving analogue signals varying within a large signal range in for instance a radio communication system. A receiver ( 300 ) includes an un-attenuated signal receiver branch ( 303 ) with a first dynamic range and at least one attenuated signal receiver branch ( 304 ) with a second dynamic range. The attenuated signal receiver branch ( 304 ) is arranged in such a way that the second dynamic range is partly overlapping the first dynamic range and together with the first dynamic range cover the large signal range of the analogue signals. The attenuated signal receiver branch ( 304 ) includes an attenuator ( 306 ) which attenuate the amplitude of an input signal by a certain value to acquire the desired overlapping second dynamic range. The signal receiver branches are connected to a third block 308 which selects between sampled bursts from the respective signal receiver branch for further processing in the receiver.

Abstract: Each transmitter/receiver pair (12) of a radio base station (10) is connected via an antenna bus (92) and radio frequency feeder (26) to antenna near parts equipment such as active antennas (40), boosters (32) and tower mounted amplifiers (152). Automatic configuration and calibration of the antenna near parts equipment is accomplished by establishing communication between the base station and each of its connected antenna near part components. Each antenna near part component sends its identification (200) to the base station over the antenna bus at power-on. Furthermore, communications selectively sent over the radio frequency feeder are monitored to determine the connectivity between individual transmitter/receiver pairs of the base station and each antenna near parts equipment. These radio frequency feeder communications are further processed to determine (252) calibration data for configuring (254) each antenna near parts equipment for optimal operation.
