Description
In this measurement we use two LPNs one for 3.3 GHz and the other one at 900 MHz. The fixed nodes LW1 and LW3 operate at both bands. The LPN and a GPS logger are attached on the top of a car and they moves with the car. We use a prerecorded LTE signal to transmit and the receiver performs IQ recording which is then postprocessed to get RSRP data. When LW1 and LW3 are used as transmitters they transmit at separate frequencies (3300 MHz and 3320 MHz or 903MHz and 914MHz) and IQ recirding is done at the LPN by hopping between two frequencies. In this case we repeat the route twice one for the first front end of the fixed node and one for the second front end of the fuixed node. When LPN is the transmitter it transmits at a single frequency (3300 MHz or 903 MHz) and the LW1 and LW3 record IQ data from both front-ends simultaneously.
