A near-field/far-field transformation for circular aperture antennas, formulated as a linear inverse problem, is here proposed. The approach takes into account for the a-priori information about the radiating and geometrical characteristics of the antennas under test, by representing the aperture field with Circular Prolate Spheroidal Wave functions.

This paper proposes the realization and preliminary characterization of a smart sensor platform for the online monitoring of the residual life of activated carbon air based filters. The platform performs the measurement to give reliable information about the filter maintenance or early warning for the presence of dangerous gases both in industrial and military scenarios. A preliminary feasibility study has been carried out to evaluate the activated carbon filter electrical impedance sensitivity to chemicals adsorption. After a detailed presentation of the employed hardware and software solutions, a description of the experimental setup is given and a preliminary proof of the assumed relationship is provided.

In this paper, we discuss the upcoming network stack LoRaWAN and its underlying modulation technology LoRa, which is an implementation of a LPWAN (Low Power Wide Area Network) and consider practical limitations that can occur when restricted Machine-to-Machine (M2M) data agreements for the connection of LoRa gateways to a cellular network are involved. We provide a theoretical estimate of the maximum possible communication range of a LoRa link depending on output power and spreading factor and illustrate a LoRa-transceiver's contrary behaviour of energy consumption and range versus the achievable data rate by means of current consumption and RF output power measurement results for different combinations of modulation parameters. Our analysis of the data overhead introduced by LoRa gateways identifies that the amount of generated backhaul network traffic can cause substantial costs for IoT service providers in case of cellular-connected gateways or limit the number of supported sensor nodes.

In this paper preliminary results from investigations of the proof of concept of a nonlinear (vibrational) bistable inductive energy harvester are presented. The main idea proposed through this paper is to exploits the benefits of the snap-through buckling configuration in terms of capability to scavenge energy from wide band vibrations and the possibility to use the beam switching between its stable states to move (contactless) a magnet inside a coil, thus producing a voltage. The simplicity of the harvester and the wide operating range of frequencies, are the two main claims of the proposed setup. The main novelty of the proposed approach arises from the coupling of the nonlinear bistable architecture with the inductive transducer and the possibility to convert the mechanical energy gained by the switching beam into an electrical signal without mechanical links. The system, in its infancy, has been observed to produce powers in the order of microwatts.

In this paper, a detailed study on the applicability of various current sensor technologies and the corresponding measurement accuracy for power consumption characterization of Wireless Sensor Networks (WSN) nodes is presented and discussed. This study is useful to plan strategies to increase the life of the network and to plan the replacement of the sensor node before a failure occurs. Power consumption management of WSN is aimed to maximize the lifetime of the network within given power constraint. In this context, each node should operate in order to ensure the highest energy efficiency without energy waste. In particular, transmission and reception often are the most consuming tasks in a wireless sensor node and must be properly characterized to maximize the WSN performance.

A novel technique based on the Field Mapping Algorithm (FMA) is proposed to gauge reflector surface smoothness from near-field reflector measurements. The proposed method provides exact information of the antenna surface with much less computation time compared with other available techniques. A few examples are given to illustrate the advantages of the new surface-analysis technique.

Monitoring system designed for biological and marine environment observation are equipped with different types of sensors related to different disciplines. For each sensor integrated in the system it is necessary to develop a driver (software/firmware) specific to its operation. This kind of approach limits the system flexibility because the addition of a new sensor involves the update of the entire software control. For this reason it is important to reduce the time and simplify the work required to integrate new sensors. This paper present GAMbUSIA (GenerAl purpose Metalanguage for instruments with Serial InterfAce) wich aim to improve code reuse and system flexibility. GAMbUSIA is a metalanguage, based on eXtensible Markup Language (XML), with which it is possible to describe the communication protocol at a high level and use (and reuse) this description instead to develop an ad-hoc driver. In order to evaluate the proposed solution, Gambusia is used to create an oceanographic sensor description in a data acquisition system.

Mobile Broadband (MBB) access networks are becoming more and more used worldwide, and the devices adopted to access them are increasing in number and complexity (smart-phones, mobile hotspots, vehicular infotainment systems). The highly dynamic nature of such scenarios calls for continuous monitoring and measurement of the network. To this aim, the Available Bandwidth is a performance metric of the utmost importance, albeit hard to estimate in uncontrolled scenarios. Shared experimental testbeds such as MONROE are becoming available to offer in-the-field MBB experimenting facilities. In this context, the SOMETIME project is focused on providing MONROE and similar testbeds with the tools to measure Available Bandwidth in MBB scenarios, also taking advantage of the benefit of SDN to perform active and passive measurements. In line with experimental activities planned by the project roadmap, in this paper we discuss the suitability of a number of publicly released ABw estimation tools when run in heterogeneous scenarios. Experimental results confirm that (i) the experimental scenario in which the tools run heavily impacts their performance in terms of accuracy; (ii) the entity of cross-traffic may have different effects on some of the tools, unacceptably undermining the estimation accuracy, depending on limitations of both the specific tools and the setup.

4G Long Term Evolution (LTE) mobile system adopts Adaptive Modulation and Coding (AMC) as a link adaption mechanism that is based on the User Equipment (UE) periodically reporting channel condition summarised through Channel Quality Indicator (CQI) which, in turn, is based on Signal-to-Interference-plus-Noise Ratio (SINR) and Reference Signal Received Power (RSRP). Although CQI has a predominant role in accurately assignment of radio resources, standards do not define how to compute CQI from SINR and RSRP, so that each UE manufacturer operates according to proprietary policies. The paper focuses on the efficient evaluation of the relationship between SINR, RSRP and CQI and also to assess how AMC affects LTE performance. To operate in a realist environment, measurements are carried out with a smartphone-based procedure.
4G LTE (Long Term Evolution)移动系统采用自适应调制和编码(AMC)作为链路自适应机制，该机制基于用户设备(UE)定期报告通过信道质量指标(CQI)总结的信道状况，而CQI又基于信噪比(SINR)和参考信号接收功率(RSRP)。尽管CQI在准确分配无线电资源方面发挥着主导作用，但标准并没有定义如何从SINR和RSRP计算CQI，因此每个UE制造商都根据专有策略操作。本文的重点是有效评估SINR、RSRP和CQI之间的关系，并评估AMC如何影响LTE性能。为了在现实环境中操作，测量是通过基于智能手机的程序进行的。
