New technologies for future high-speed Internet: IHP coordinates project for next-generation mobile


The pan-European project “5G-XHaul” which will evaluate the infrastructure to form the next generation of communications networks and services. The goal of the project is to find solutions to the rapidly growing demand for broadband connections, which require new, powerful, cost-effective networks in order to connect the access points.

The next generation of mobile telephony called “5G” will make one thing possible: Internet is always accessible. In 2020, dead spots will be a problem of the past, if researchers are able to implement their ambitious goal worldwide.



Scientists of IHP – Innovations for High Performance Microelectronics coordinate the pan-European project “5G-XHaul” which will evaluate the infrastructure to form the next generation of communications networks and services.

The project partners include industrial companies, research institutes and universities from four European countries. The goal of the project is to find solutions to the rapidly growing demand for broadband connections, which require new, powerful, cost-effective networks in order to connect the access points.

Which parameters must be improved for networks of the future in order to meet the demand for broadband communication? “Universities and companies work closely together in our project which helps us to clarify such questions. The industry sets the demand.

The researchers will find possible solutions. 5G-XHaul will help to ensure that every smart phone owner can rely on an uninterrupted network connection with a high data rate,” said Prof. Eckhard Grass, scientist at IHP.

New powerful cost-effective networks are necessary in order to connect the access points, also called base stations, with the core network of the telecommunication providers. A particular focus of the project will be on establishing dynamically adaptive communication for transport hubs including railway stations and airports and at major events because network connection must be dynamically adapted to the spatial and temporal needs.

“5G-XHaul proposes a converged optical and wireless network solution able to flexibly connect Small Cells to the core network. Exploiting user mobility, our solution allows the dynamic allocation of network resources to predicted and actual hotspots. Due to the dynamic allocation of network resources we can serve the needs of the users.”, Prof. Grass explains.

Field trials are already underway. The Bristol is Open project is a joint venture between the council and university to provide three new fast networks in the centre of Bristol. 5G mmWave company Blu Wireless Technology is trialling its 60 GHz ‘Lightning’ Modules to provide wireless backhaul to the project.

Mark Barrett, CMO of Blu Wireless Technology, said of the project, “5G-XHaul is an exciting collaboration set up to establish the ways that networks of the future will operate. For Bristol is Open, Blu Wireless is deploying its mm-Wave technology to extend the fibre network. Millimetre wave wireless technology will form a key aspect of 5G and we are very pleased to be involved in this important project”.

The project “5G XHaul” is part of the 5G Infrastructure Public Private Partnership (5G-PPP). This joint initiative of the European information and communications industry and the European Commission will examine the current infrastructure and their limitations and specify requirements for the next generation of communications networks and services. Based on the requirements technical solutions will be investigated and tested. The project “5G XHaul” is funded by the EU program “Horizon 2020” with around 7.3 million euros. It runs over a period of three years, until June 2018.

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
