EuCNC Deadline Extended to 24th February

The EuCNC 2017 deadline for the submission of papers, workshops, special sessions and tutorials has been extended until Feb. 24th.

EuCNC is sponsored by the European Commission, IEEE ComSoc and EURASIP, and is being held in Oulu, Finland, from 12th to 15th June 2017.

All information is available at

The conference will include:
— regular sessions with papers from the open call (to be submitted to IEEE Xplore), the call being available at;
— workshops, the call being available at;
— special sessions, the call being available at;
— poster sessions, the call being available at;
— tutorials, the call being available at;
— panels;
— keynote talks;
— demos and exhibitions, the call being available at

EuCNC is very important for networking with other EU projects, and the Commission Officers!

iCIRRUS “Ethernet in the fronthaul” paper in Optical Fiber Technology

A paper overviewing the advantages and challenges of using Ethernet in the fronthaul, and presenting the iCIRRUS vision of the future fronthaul is being published.  It is currently “in press”, see: N.J. Gomes et al., Fronthaul evolution: From CPRI to Ethernet, Opt. Fiber Technol. (2015),
The co-authors are Philippe Chanclou (Orange), Peter Turnbull and Anthony Magee (ADVA Optical Networking) and Volker Jungnickel (HHI).

iCIRRUS Kick-off Meeting 5th Feb 2015

iCIRRUS (intelligent Converged network consolidating Radio and optical access aRound USer equipment) is a 3.8 million Horizon 2020 collaborative project coordinated by Dr Nathan Gomes in the School of Electronic and Digital Arts (EDA) and consisting of 10 partners from five European countries.


The official launch (‘Kick-off meeting’) took place at the University of Kent in Canterbury and after the welcoming address by Professor Philippe de Wilde, Pro-Vice Chancellor for Research and Innovation, consortium members briefly introduced themselves, their organisation and the roles they are to play in the project. The remainder of the morning session was then taken up by presentations and discussions regarding the technical and administrative management of the project.

kickoff-technicaldiscussionThe afternoon session was dedicated to discussing individual work packages (WPs 2, 3 4 and 6) with opening presentations by WP leaders and input and suggestions from consortium members. The work in WP5 depends to some degree on the input from WPs 3 and 4 and will not start until month 9, but partners were reminded to look out for any recommendations and potential input that might be useful. WP6 is concerned with dissemination, exploitation and standardisation discussions centred on initial thoughts about dissemination targets and exploitation strategy.

The meeting was rounded off with an enjoyable and relaxing dinner at one of Canterbury’s excellent restaurants.

FPGAs Target Remote Radio Heads

By Loring Wirbel


Remote radio heads (RRHs)—small mixed-signal platforms attached to walls and telephone poles—play an important role in macro cellular networks by combining RF/IF analog functions and digital front ends. As the RRH becomes a main element in small-cell networks based on a cloud-RAN (C-RAN) topology, FPGAs may play an important part. These devices could also become common in centralized baseband-unit (BBU) platforms for C-RANs.


In a typical C-RAN, several RRHs share a central baseband-processing pool. Initial implementations replace the base station with the RRH, supported by central BBUs. This approach is possible using the Common Public Radio Inter­face (CPRI) over fiber, which supports up to 40km fronthaul links. The BBU can perform baseband processing in the traditional fashion—using a combination of DSPs and CPUs—or it can employ more-general-purpose processors, such as Intel’s Xeon, and accelerators.


The challenge with the C-RAN approach is the need for high bandwidth between a simple RRH and the central BBU. So far, this requirement has limited the C-RAN to operators such as China Mobile that have access to dark fiber. The industry, however, is considering new partitions between the BBU and RRH to reduce the fronthaul bandwidth requirements and initiate broader deployments. FPGAs in the BBU still must confront a dual-switching architecture that incorporates both Ethernet and I&Q data switching, as well as I&Q data channels based on either CPRI physical links or future 10Gbps extensions of Synchronous Ethernet.

iCIRRUS kick-off meeting

The iCIRRUS kick-off meeting took place in Canterbury on 5th February, 2015.  All partners had representatives present, and there were some very interesting dicussions on Ethernet in C-RANs and use cases for D2D and C2C communications in the afternoon.  And, we had a good dinner in the city in the evening!

Kick-off meeting preparation: agenda

The agenda for the iCIRRUS kick-off meeting on Thursday, 5th February has been distributed to attendees.  The meeting will start with a brief address from Professor Philippe De Wilde, the University of Kent’s Pro-Vice-Chancellor for Research and Innovation.  It will end with dinner in the historic city of Canterbury.

iCIRRUS starts

The iCIRRUS EU project started on 1 January, 2015.  Following the virtual meeting held prior to the start (in December 2014), we have been preparing for the face-to-face kick-off meeting in Canterbury.  We have also been preparing the pre-financing for partners (very important!).
