In late 2015, Plextek Ltd demerged into a number of separate legal entities, formally spinning out four new product companies: Blighter Surveillance Systems Ltd, Redtail Telematics Ltd, Plextek RFI and Telensa Ltd.
Blighter Surveillance Systems offers a range of lightweight, high-performance surveillance radars into many market sectors. Redtail Telematics provides turnkey vehicle telematics services to the fleet management and automotive insurance markets. Telensa is the leading provider of street lamp monitoring and control systems.
At the time of the demerger, the original consulting business split into two parts. The millimetre-wave IC design business was spun out as Plextek RFI, which has since been sold and renamed ‘PFRI’. The remainder of the consultancy business was moved to this legal entity – Plextek Services Ltd – but continues to trade as Plextek.
