Standards are needed to enable cooperation while promoting competition. Within the framework of a standard, the companies involved in the standardization process contribute and agree on appropriate technical specifications to ensure diversity and compatibility, and facilitate worldwide commercial deployment and evolution. Those parts of the system that can create competitive advantages are intentionally left open in the specifications. Such specifications are extensive, complex, and minimalistic. This makes telecommunication standards education a difficult endeavor, but it is much demanded by industry and governments to spur economic growth. This article describes a methodology for teaching wireless communications standards. We define our methodology around six learning stages that assimilate the standardization process and identify key learning objectives for each. Enabled by software-defined radio technology, we describe a practical learning environment that facilitates developing many of the needed technical and soft skills without the inherent difficulty and cost associated with radio frequency components and regulation. Using only open source software and commercial of-the-shelf computers, this environment is portable and can easily be recreated at other educational institutions and adapted to their educational needs and constraints. We discuss our and our students' experiences when employing the proposed methodology to 4G LTE standard education at Barcelona Tech.Peer ReviewedPostprint (author's final draft

    A Framework for the Design of a Mobile-Based Alert System for Outpatient Adherence in Nigeria

    Nigeria ranks among the countries with the highest child and maternal mortality rate. Chronic diseases are the most common contributors to the diseases burden in Nigeria most especially Malaria, Tuberculosis (TB) and HIV/AIDS. Adherence to long-term therapy in out-patient condition is required to reduce and curb the prevalence of these diseases. Poor adherence to long-term therapies severely compromises the effectiveness of treatment; making this a critical issue in population health both from the perspective of quality of life and of health economics. This work introduces a m-technology based system that will provide an easy way of complying with drug regimen. It will make use of the Short Messaging Service (SMS) of mobile phones to provide reminders at dosing times. It will design architecture for mobile health interventions and develop a prototype SMS-based system to improve out-patient adherence. This system will be deployed over a period of time at selected hospitals and chronic disease management centers in selected states in Nigeria, and the adherence rates measured via health outcomes and evaluated. This would provide a significant positive return on investment through primary prevention (of risk factors) and secondary prevention of adverse health outcomes. It will also inform predictions of future population health outcomes predicted by treatment efficacy data. Keywords: out-patient, m-technology, adherence, chronic diseases, Nigeria, SM

    Ethernet - a survey on its fields of application

    Get PDF
    During the last decades, Ethernet progressively became the most widely used local area networking (LAN) technology. Apart from LAN installations, Ethernet became also attractive for many other fields of application, ranging from industry to avionics, telecommunication, and multimedia. The expanded application of this technology is mainly due to its significant assets like reduced cost, backward-compatibility, flexibility, and expandability. However, this new trend raises some problems concerning the services of the protocol and the requirements for each application. Therefore, specific adaptations prove essential to integrate this communication technology in each field of application. Our primary objective is to show how Ethernet has been enhanced to comply with the specific requirements of several application fields, particularly in transport, embedded and multimedia contexts. The paper first describes the common Ethernet LAN technology and highlights its main features. It reviews the most important specific Ethernet versions with respect to each application field’s requirements. Finally, we compare these different fields of application and we particularly focus on the fundamental concepts and the quality of service capabilities of each proposal
