Abstract: The invention provides for an electronic apparatus for amplifying a plurality of different frequency bands of a wireless telecommunication signal. The apparatus comprises: a first antenna configured to receive a wireless communication signal; a filtering module configured to: receive an indication of a plurality of different frequency bands to be filtered; and, selectively filter the wireless telecommunication signal according to the received indication to form a filtered wireless telecommunication signal; a filter controller configured to provide the indication to the filtering module; and, an amplifier configured to amplify the filtered wireless communication signal.

Abstract: A frequency division duplex radio access telecommunications terminal comprises a transmitter for transmitting a transmission signal at a first frequency. The transmitter is arranged to switch between a peak power mode in which the transmission signal is transmitted at a peak power level, and a reduced power mode. A receiver receives a reception signal at a second frequency different from the first frequency. A detector measures the signal strength of the reception signal. A controller is arranged to cause the detector to measure the signal strength of the reception signal whilst the transmitter is operating in the reduced power mode, and at a predetermined time before the transmitter switches to the peak power mode.

Abstract: The invention provides for a telecommunications system and related method of handover from a first radio access technology to a second radio access technology for a mobile radio communications device within a mobile radio communications network, and including determining a timing advance value associated with the second radio access technology, and the method employing positional data of the device within the network for determining the said timing advanced value.
