Red-M is a professional services company that provides consultancy, design and implementation services to the wireless communication sector, helping organisations fully realise the benefits of wireless technologies. In April 2005 Red-M merged with Interregnum Wireless Holdings Ltd and Cellular Design Services Ltd to form the Red-M Group.

Red-M helps create mission critical wireless networks and past successful projects include most of the major airports in the UK (Heathrow), large shopping centres (Meadowhall), sporting venues (Millennium Stadium) and train stations (Waterloo).

Amadeus, alongside the company’s other investors, Apax Partners, Interregnum and Pi Capital, supports the efforts of Red-M to establish itself as the leading provider of professional services in the wireless communications sector.
