The 5TONIC facility is an open research and innovation laboratory focusing on 5G technologies founded by IMDEA Networks and with participation of the University Carlos III of Madrid. The objective of 5TONIC is to create a global open environment where members from industry and academia work together in specific research and innovation projects related to 5G technologies with a view to boost technology and business innovative ventures. The laboratory will promote joint project development and entrepreneurial ventures, discussion fora, events and conference sites in an international environment. The 5TONIC laboratory includes a solid baseline of facilities, infrastructure and equipment to support advanced experimentation in the 5G virtual network function and wireless systems areas. In other words, 5TONIC will serve to show the capabilities and interoperation of pre-commercial 5G equipment, services and applications, by leading global companies in the 5G arena. Apart from the initial members, 5TONIC welcomes new members to join and gain from the benefits of an advanced research and innovation laboratory, oriented to research, debate, field-testing and demonstration of all technologies and equipment to support 5G communications, services and applications. The main 5TONIC research & innovation laboratory site is located at IMDEA Networks Institute, a research institute on the forefront of technological innovation and with an extensive track record in European 5G Research Projects. IMDEA Networks is one of the main leaders at European level in the field of 5G networks.
