Free-Space RF Path Loss Measurement Solution

The National Physical Laboratory wishes to procure a measurement solution including an RF transceiver to measure free-space path loss at 77GHz where absorption will primarily be caused by atmospheric water vapour, fog or rain. The solution must be able to measure loss over at least 50 metres but ideally at greater ranges up to 250 metres. The equipment must be robust, weatherproof (IP65-rated or above) and transportable. It will be used as part of a study into autonomous vehicle sensor performance degradation caused by weather. Participation is via the London Universities eSourcing Portal. Participants must provide qualification information.
