A hardware testbed to characterise propagation for wideband indoor millimetre-wave channels in the 57-60 GHz band is described. The testbed is based on a direct conversion architecture and uses commercial-off-the-shelf components to transmit and receive the millimetre-wave signals and generate/capture the corresponding baseband waveforms. Tone-test measurements have been used to quantify the impact of hardware impairments in the testbed, and indicate that compensation for the IQ-imbalance arising from the mixers is required. The attenuation introduced by common building materials has also been experimentally investigated using a vector network analyser over the 33-50 GHz millimetre-wave bands. Pine wood was found to introduce approximately 25 dB attenuation, while the attenuation due to drywall was approximately 1.4 dB. These results suggest that internal partitions made from drywall may not be sufficient to isolate co-channel systems in a building. Measurements using sponge material also indicate materials with high water content experience increased attenuation.
