RAPID5G is entering its final phase

The 11 European and Japanese partners of the RAPID5G consortium have worked hard on developing novel 5G solutions and are eager to show the results! In the final phase of the project the RAPID5G technology will be showcased and demonstrated live during two field trials. The field trials will take place in high user density public areas in a shopping mall and a football stadium. The first live demo will be from 10th to 12th July in the BlueCity shopping mall in Warsaw, Poland. The second field trial will take place from 7th to 10th August in the Gamba Osaka stadium in Osaka, Japan.

Workshop on Millimetre-wave technology for 5G access, fronthaul and backhaul

The RAPID-5G project co-organised a workshop on mm-wave technology at EuCNC on 12th June, in Oulu, Finland. Together with the projects mmMAGIC (H2020 5GPPP) and 5G MiEdge (H2020 Eu-Japan).  There were two sessions, the first focussing on fronthaul and backhaul links and chaired by Professor Nathan Gomes, University of Kent, of the RAPID-5G project, and the second focussing on access technologies, chaired by Dr Mehrdad Shariat of Samsung R&D Institute, from the mmMAGIC project.

The workshop programme can be accessed here.

It’s time to start 5G!

RAPID member Exatel participated in the PLNOG16 conference to inform about the hot topic that is 5G. Exatel gave a presentation on the current status of the LTE successor: key functional requirements, standardization and to up-to-date R&D projects. In particular, the Polish telecom operator presented the RAPID project to its peers.

This article represents the topic of the presentation in the PLNOG16 conference by Michał Szczęsny from Exatel in Warschau on March 1, 2016. More information about the 16th PLNOG conference, which is the biggest conference for Polish network operators can be accessed here.

New world record in digital radio transmission

Spectral efficiency of 10 bit / s / Hz at 60 GHz experimentally proven

Scientists of the Center for Semiconductor and Optoelectronics have made a new breakthrough in radio data transmission, which could simplify the rollout of future 5G mobile networks. Within the scope of the European research projects IPHOBAC-NG and RAPID5G, new technologies respectively system architectures have been developed, which enable a highly efficient radio transmission even at highest radio frequencies.

For experts a picture with significant meaning: The so called constellation diagram of a radio signal modulated with 1024 QAM after the radio transmission.

At the end of last year researchers of University of Duisburg-Essen announced a sensation together with their American and German colleagues from Corning and Finisar. Believe it or not, for the first time an overall volume of data of ten gigabit per second (10 GBit/s) was successfully transmitted by radio within a channel bandwidth of only one Gigahertz (1 GHz). Thereby a high radio frequency of 60 GHz was employed. Outstanding about these experiments is the enormous spectral efficiency of 10 Bit/s per Hz radio bandwidth that has been achieved at 60 GHz radio frequency. “We have achieved this through the development of novel so called photonic radio transmitter (CPX) and new system architectures, with which we could transmit complex modulated radio signals (1024 QAM) at a radio frequency of 60 GHz for the first time.”

The term “spectral efficiency” thereby means the number of bits per second, which can be transmitted within a certain radio bandwidth. Thus for a spectral efficiency of 1 Bit/s/Hz and a channel bandwidth of 1 GHz, data transmission of 1 GBit per second is possible. Important to note at this point is, that radio channel bandwidths are firmly prescribed by national regulation bodies. Therefore they cannot be simply exceeded by network operators in order to transmit more data in a given time. This means, that an increase of data transfer rate is directly linked to an enhancement of spectral efficiency. That this is now been achieved at a radio frequency of 60 GHz is especially important, because at lower frequencies worldwide just very small channel bandwidths of few 10 MHz may be used. Only in the 60 GHz band national regulation bodies allow the usage of a radio channel with a bandwidth of 1 GHz and more.

Still much room for improvement

Incredibly, the project manager see even much more potential for improvements. “Our next aim is the usage of even higher radio frequencies in the THz region (above 300 GHz), where we can use yet much higher radio channel frequencies. Thus we want to transmit up to 100 GBit/s over the radio”, according to Professor Andreas Stöhr of University Duisburg-Essen.

New coherent photonic mixer for coherent radio-over-fiber wireless systems

The best overall paper prize of the MWP conference 2015 was awarded to Rattana Chuenchom for her research and presentation on the new  developed coherent photonic mixer (CPX).

The presented photonic mixer (CPX) is a joint development of the University of Duisburg-Essen and Finisar within the IPHOBAC-NG project. This CPX enables to upconvert optical baseband signals transparently into the millimeter-wave frequency range by optical means. The carrier frequency of the generated radio signal can be tuned in an enormously wide frequency range from DC to 110 GHz . So far, the CPX is suitable not only for today’s wireless networks such as 3G, 4G, but also for future 5G networks and even for research networks that operate at even higher carrier frequencies. The CPX has been successfully employed for CRoF wireless backhaul measurements within the RAPID5G project.

UDE performs field trials for long distance mm-wave communication

UDE field trial2

UDE has performed mm-wave radio-over-fiber transmission experiments in the rural areas of Duisburg. The link was established by high gain antennas operating in the E-band (60-90 GHz) and delivered multiple Gbit/s over more than 200 m wireless distance. The fast setup of the link makes the system applicable for emergency scnearios as well as cost-effective hook-up of rural areas.
