| Popis: | Both massive multiple-input multiple-output(MIMO) technology and use of frequencies in the range24–100 GHz are considered essential for upcoming 5G systems.Measurements of the new type of channels are needed, but thisis challenging due to the large number of channels in massiveMIMO and the short wavelength in the 24–100 GHz channels(so-called mmWave channels). This article describes a soundersystem capable of measurements in both types of channels.While the same sounding system supports simultaneous massiveMIMO and mmWave channels, the number of channels in eachband and in total is in practice limited. For massive MIMO inthe 300–6000 MHz band alone, arrays with up to 128 receiver(Rx) elements are possible, receiving from 16 independent mobiletransmitter (Tx) antennas, where all channels are measuredwithin 1.3 ms and in a 200 MHz bandwidth. To the authorsknowledge, this is the first sounding system with this numberof channels and a speed necessary for measuring the dynamicchannels in typical application scenarios. For mmWave channelsthe sounder operates in the range 18–40 GHz. For these bandsup to 2 Tx elements and 16 Rx elements can be measured. Inaddition, the paper describes some measurements in both amassive MIMO setup in an indoor sports arena and a mmWavesetup with a handheld device containing a 7-element array. |
