Spectrum crunch is a severe issue for below $6$GHz wireless communications. Cognitive radio and Dynamic Spectrum access (DSA) based on geographic database are promising techniques to cope with this spectrum shortage. TV White Space (TVWS) usage relies on unlicensed secondary DSA under the principle on a non-harmful interference with incumbent users, allowing to use UHF channels whose availability is changing over time and space. In order to do so, a well-designed physical layer is required in order to reach accurate frequency localization while being highly flexible. We describe field-test experiments done with an implementation of the BF-OFDM (Block-Filtered OFDM) physical layer on versatile and portable hardware prototyping boards. Field-trials results confirm the potential of BF-OFDM for fragmented spectrum access and spectrum sharing usage.

Mobile communication networks are typically based on a fixed spectrum assignment policy. However, a portion of the assigned spectrum is used only sporadically and with some geographical variations. The scarcity of spectrum and its inefficient utilization impede meeting the growing user demand for higher capacity and availability. To help solving such issue, the 5G PPP project SPEED-5G has defined a concept that allows dynamic allocation of spectrum, thus optimising the usage of scarce spectral resources. While the project has defined concepts and components in its first phase, several experiments have been designed and made and first results are now available. The objective of this paper is to describe the demonstrator setup and selected Proof-of-Concepts, their mechanisms and the results achieved.



16:36 – An Adaptive Channel Quality Metric for Ultranarrowband Systems

Tomaz Solc and Carolina Fortuna (Jozef Stefan Institute, Slovenia)
In this paper we propose an adaptive channel quality metric that is suitable for uplink channel estimation in ultra-narrowband networks. The proposed metric relies on channel measurements rather than on packet information, therefore it doesn’t need a large number of packets to initialize, and is simple enough that can be computed per channel for a large number of channels. Our results show that the proposed metric should be able to identify channels with the least amount of interference for a wide range of expected received packet powers.



16:54 – IP over ICN Goes Live

Information-centric networking (ICN) has long been advocating for radical changes to the IP-based Internet. However, the upgrade challenges that this entails have hindered ICN adoption. To break this loop, the POINT project proposed a hybrid, IP-over-ICN, architecture: IP networks are preserved at the edge, connected to each other over an ICN core. This exploits the key benefits of ICN, enabling individual network operators to improve the performance of their IP-based services, without changing the rest of the Internet. We provide an overview of POINT and outline how it improves upon IP in terms of performance and resilience. Our focus is on the successful trial of the POINT prototype in a production network, where real users operated actual IP-based applications.



17:12 – Feasibility of Gateway-less IoT E-health Applications

Machine-to-Machine (M2M) communications are a key enabler of Internet of Things (IoT) applications. One domain with growing interest in M2M/IoT is e-health, either for self-monitoring, home monitoring, or hospital systems. However, current sensing devices in this domain rely on short-range communication protocols that require a gateway (GW) for Internet connection. Smartphones have been proposed as GWs in mobile M2M communications due to their enhanced connectivity and sensing capabilities. However, the GW functionality impacts on the smartphone usability, causing undesirable battery depletion and the smartphone itself increases the overall cost of e-health solutions. In this work, we propose converging e-health devices and Wi-Fi towards direct Internet access through the existing Wi-Fi infrastructure and by-passing current GWs. We use recent low-cost ultra low-power Wi-Fi modules and feature them with M2M capabilities supporting their integration in an interoperable e-health framework. We present results on end-to-end latency and power requirements within a concrete e-health use case that show the feasibility of the proposed GW-less solution.
