Abstract: Embodiments for calibrating a radiofrequency (RF) test station with a portable RF test station calibration device are disclosed. In one example, a portable RF test station calibration device comprises an RF power meter, a power sensor, and a computing device. The computing device may be configured to connect to the RF test instrument and to the RF power meter. The computing device may further comprise instructions executable by a logic subsystem to control the RF test instrument to transmit one or more RF signals having requested transmission values, receive measured transmission values from the RF power meter, determine a difference between the requested transmission values and the measured transmission values, and send a calibration value to the RF test instrument to be stored at the RF test instrument, the calibration value derived from the difference between the requested transmission values and the measured transmission values.

Abstract: An apparatus and process for allocating carriers in a multi-carrier system is described. In one embodiment, the process comprises determining a location of a subscriber with respect to a base station, selecting carriers from a band of carriers to allocate to the subscriber according to the location of the subscriber with respect to the base station, and allocating selected carriers to the subscriber.

Abstract: A transceiver apparatus comprising a software-definable-radio-transceiver architecture. The transceiver apparatus comprises at least one up-conversion path including at least one configurable micro-electro-mechanical-system (MEMS) transmit filter communicatively coupled to transmit output from a digital-to-analog converter to an antenna, and at least one down-conversion path including at least one configurable-MEMS-receive filter communicatively coupled to transmit signals received from the antenna to an analog-to-digital converter. The at least one configurable-MEMS-transmit filter prevents interference on the up-conversion path from signals transmitted from the antenna. The at least one configurable-MEMS-receive filter prevents interference on the down-conversion path from signals transmitted to the antenna. A plurality of upconversion and downconversion paths can operate simultaneously and on different channel frequencies.
