1. Under the spotlight

Bringing your attention to a matter in this issue of the Newsletter

The goal in the virtualisation of radio resources is to serve multiple Virtual Network Operators (VNOs) over the same physical infrastructure, while offering isolation and flexibility in addition to network element abstraction and multi-RAT (Radio Access Technology) support. Instead of splitting the available radio resources among VNOs, they are aggregated and jointly manage by a higher level entity. VNOs request wireless capacity from a set of physical network providers to serve their subscribers, thus, not having to deal with the physical infrastructure, but rather only with the required capacity. This approach offers pay-as-you-go Connectivity-as-a-Service to VNOs, while enabling new business models for network operators and infrastructure providers. As illustrated in ‎the figure, the key concept of Virtual RAN (VRAN) corresponds to the one of Virtual Machines (VMs) in computing. In RAN virtualisation, in contrast to RAN sharing, the physical infrastructure is not transparent to the clients. By means of isolation, services with different protocols, algorithms, and requirements for quality of service can be offered over the same physical infrastructure.

2. People

Information about incoming and outgoing people, besides other related news.

GROW is receiving one more member. Since mid-January, Andrea Marrota, an M.Sc. Student from University of L’Aquila, Italy, is working in his thesis. We wish him good luck.

GROW has hosted Dr. Slawomir J. Ambroziak (Gdansk University of Technology, Gdansk, Poland), in a COST IC1004 Short Term Scientific Mission, in the period of Jan. 12th to 16th. This stay, resulting from an existing collaboration, produced very interesting results.

5. Projects

News about the several projects in which GROW is involved.

COST IC1004 – http://www.ic1004.org

A contribution entitled “Virtualised and Cloud based Architectures” was edited for the COST book Cooperative Radio Communications for Green Smart Environments. The paper presented at the COST meeting was chosen as selected scientific topic for the 10th newsletter. Sina Khatibi is going to submit the abstract version of the paper for the 10th project Newsletter. Slawomir J. Ambroziak (Gdansk University of Technology, Gdansk, Poland), was hosted in GROW under a Short Term Scientific Mission, for joint work in Body Area Networks.

 

LEXNET – http://www.lexnet-project.eu

A report is being prepared on SAR simulations for a tablet usage, and work is starting concerning SAR simulations with smart glasses, within WP2. Concerning WP5, OPNET simulations on optimisation of locations for network topologies are already finished; work is now progressing on the definition of a cost function taking EMF as a KPI for network management/performance analysis into account. The New Work Item on “Development of a methodology on day to day assessment of EMF exposure to the population” that was proposed to CENELEC was accepted for discussion.

 

MCN – http://www.mobile-cloud-networking.eu

Work is being done on the implementation of VRRM in the OAI LTE base station emulator, as well as on the integration of traffic scenarios. A talk on RANaaS and a demo entitled “Capacity-as-a-Service” were given in the Innovation on the Cloud Workshop, organised by FP7 MOBIZZ project (www.mobizz-project.eu), an event congregating several FP7 projects.

 

NEWCOM# – http://www.newcom-project.eu

Sina Khatibi presented the work “Optimisation Approaches for Virtual Heterogeneous Networks”, based on the latest achievement in JRA1.1.2.2 at the project meeting.

 

FAQtos – http://faqtos.pt

The 2015 edition of Prémio FAQtos has been ongoing, with the 59 groups scheduled to deliver their intermediate report by February 6th. Continuous monitoring of EMFs was launched in Valongo, with 5 monitoring stations, with 1 further station installed in Felgueiras. Some seminarswere held on some schools during January, with some more already scheduled for February.
