Small cells are expected to play an important role in future mobile networks to meet the rapidly increasing capacity demand. However, this requires that cost efficient backhaul solutions are found. This is a very challenging task given the large number of small cells that must be connected. In this paper we propose a set of practical methods that mobile operators can use as tools when planning small cell backhaul networks. The tools can help operators find the best way to connect the base station nodes and which technology to use on each link. Two methods are proposed for planning fiber-only networks. Fiber only solutions are interesting since long term backhaul solutions are expected to be dominated by fiber links and can be used to find heuristic solutions to multi-technology problems by e.g. replacing some fiber links with radio links. Optimal fiber-only networks with a tree topology can be easily found by a minimum weight spanning tree algorithm. By introducing a new metric we show that more resilient ring topology based solutions can be found by solving a traveling salesman type of problem. For heterogeneous multi-technology backhaul networks we propose a Mixed Integer linear Programming (MIP) problem formulation that allows inclusion of a wide range of requirements and constraints. The solutions can be made robust against varying traffic conditions by specifying capacity demand for different scenarios and both point-to-point and point-to-multipoint type of technologies can be included in the optimization. To verify the methods an example case study is performed for a small city.

This paper reports results and experiences from the validation process performed to experimentally evaluate the design of the Future Internet Architecture MobilityFirst. Next, we discuss possible evaluation strategies that take into account the desired scale and degree of realism necessary for validation. Specific examples of experimental evaluations for the MobilityFirst architecture running on the ORBIT and GENI testbed are given. These include routing and name resolution scalability experiments on ORBIT, service-level evaluations on GENI, and real world experimentation with end-users using both ORBIT and GENI capabilities. Selected results from these experiments are presented and discussed in context of MobilityFirst evaluation goals.

Elastic Optical Networks (EON) are characterized by a flexible grid in which the so called “frequency slots” are allocated dynamically and based on the client signal data rate and modulation format and rely on bandwidth variable transceivers (BVT) and bandwidth variable cross-connects (OXC). A control plane(CP) is used for the efficient and dynamic provisioning of optical connections with recovery. Such emerging optical technologies bring new requirements to the CP related to the efficient flexible spectrum allocation, co-routed connection setup and dynamic and low latency configuration of optical parameters.

We have quantified equalizer complexity for transmitting dual-polarized 6-LP modes (LP01, LP11a, LP11b, LP21a, LP21b and LP02) of 112 Gbit/s m-ary QAM (m=4, 16, 32, 64, 256) single carrier signals over 20 km step-index few-mode fiber. The transmitted signals are strongly coupled and recovered using 12×12 multiple-input multiple-output (MIMO) adaptive digital signal processing (DSP). Time domain equalization (TDE) is realized to implement the linear adaptive MIMO module that is implemented in blind mode using conventional constant-modulus-algorithm (CMA) for finite impulse response (FIR) adaptive filter continuous update. Moreover, the benefit of employing hard-decision (HD) and soft-decision (SD) FEC for higher order QAM variants are also discussed.

The 3GPP Long Term Evolution (LTE) wireless technology provides high data rates and improved latency to the end users. Such improvement is obtained from the advanced MAC and PHY layer techniques, which exhaust the battery life of the User Equipment (UE) quickly. To save the power of UE, 3GPP LTE proposes a mechanism called Discontinuous Reception Mechanism (DRX) which lets the UE switch its RF module off when data needs not be transmitted. In this paper, we have developed an analytical model to derive the DRX power saving obtained by the UE in LTE system. Different from other work, the RRC (Radio Resource Control) states transition is considered. The time period for power saving operation is divided into several independent parts to derive the power consumption and the transmission delay. In addition, we introduce the real power consumption model into the derived power saving model to obtain the truly power consumption. The analytical results show the UE with lower packet arrival rate can effectively save more power when entering RRC_IDLE state, and there is a trade-off between the power consumption and the transmission delay.

The elastic optical networks paradigm offers a competitive solution in terms of resource utilization to cope with the ever-increasing traffic demand. Specifically, the ability to make a number of previously fixed transmission parameters tunable, for example the data rate or channel spacing, requires an evolution of the node architecture. To fully benefit from elasticity, the data plane should evolve towards a software-defined architecture. In this paper, we report the work carried out in the ICT IDEALIST project and in particular the data plane solutions towards 1Tb/s optical networks with flexgrid and flex-rate technology. Flexibility requires changes in optical cross-connect, transponder as well as in the digital layer. The consortium builds pre-commercial experimental testbeds to validate the proposed building blocks and to analyze candidate applications.

In the framework of the forthcoming 5G telecommunication system, the definition of realistic use cases and prototypes strongly connected to them is key in order to demonstrate how well emerging enabling technologies can fulfil the challenges introduced by the 5G Heterogeneous Network (HetNet) architecture. This paper shows how millimeter wave (mmWave) technologies can be properly assessed by selecting real-life use cases and then deriving out of experimental platforms significant system Key Performance Indicator (KPI). Finally, the status of mmWave activities in standards bodies is described, highlighting which bodies are to be addressed for a successful go-to-market of such emerging technology.

Millimeter-wave (mmW) communication is envisioned to be a promising technology to cater for the continuous growth of backhaul link capacity demand. To compensate the severe path loss for mmW signals, the mmW backhaul link typically employs beam alignment between transmitter and receiver to achieve essential antenna gain. To reduce deployment cost and improve operational efficiency, it is desired to implement a self-organized backhaul link, so that the beam alignment can be achieved automatically with minimum human effort. To this end, this paper proposes a self-organized dual connectivity establishment procedure for the mmW backhaul link to support autonomous beam alignment and dynamic routing.

This paper addresses the virtualisation of wireless access in order to provide the required capacity (data rate) to a Virtual Base Station (VBS). The approach is based on a Virtual Radio Resource Allocation algorithm, OnDemandVRRA, which manages the allocation of the physical radio resources to VBSs' end-users, in order to follow the contract and maintaining isolation among VBSs, according to the type of guarantees of the VBSs, the amount of contracted capacity, and VBSs' utilisation. Taking the variability of the wireless medium into account, the algorithm continuously influences the RRM mechanisms, namely admission control and MAC scheduling, to be aware of the VBSs' state relative to the service level agreement, in order to compensate for this variability. The algorithm has been tested to evaluate its behaviour, concerning the amount of VBSs created over a given geographical area served by a set of base stations. It can be concluded that changing the quantity of created VBSs as well as the contracted data rate in the cluster, GRT VBSs get their minimum contracted data rate. It is also verified that the best Radio resource Unit (RU) efficiency is achieved when the strategy for the overall capacity provision is to limit the capacity contracted by GRT VNets, overbooking the capacity contracted by BE VNets. In this case, the RU efficiency increases 30% comparing to the situation where the overbooking is done by GRT VBSs.

A full-polarimetric model of the power delay profile (PDP) is proposed in a large hall scenario and validated with polarimetric measurements of a large open hall radio channel under Line-of-Sight conditions at 1.3 GHz. The measured radio channels were processed by the high-resolution parametric estimator RiMAX to estimate both the polarimetric specular multipath components (SMC) and dense multipath components (DMC). The model of the full-polarimetric distance-dependent PDP was derived from which the depolarization mechanisms are presented. In addition, it is demonstrated that the room electromagnetics theory applies to our scenario across all polarization links. The validity of the proposed model is provided by the good agreement between the polarimetric data and models. The results of this contribution highlight the fact that a complete polarimetric description of all propagation mechanisms is desired in polarimetric radio channel models.
