The needs for accessibility of cellular phones to Web based client-server systems are increasing. For this access, efficient management of the context data must be implemented on the cellular phone. However, physical restrictions of the cellular phone make it difficult to manage context data by applying the conventional methods. Additionally, the conventional methods do not show sufficient perf...

As the knowledge society matures, not only distant, but also off-line universities are trying to provide learners with on-line educational contents. Particularly, high effectiveness of mobile devices for e-Learning has been demonstrated by the university sector, which uses distant learning that is based on blended learning. In this paper, we analyzed previous m-Learning scenarios and future tec...

With the rapid growth in penetration rate of mobile devices and surge demand for data services, small cells backhaul networks have become critical focus next-generation network development. Backhaul requirements within current wireless are almost asymmetrical, with most traffic flowing from core to handset, but 5G will require more symmetrical capability. The deployment placement transceivers c...

BACKGROUND Cardiac pacemakers and implantable defibrillators are potentially susceptible to electromagnetic interferences as they have complex circuitry for sensing and communication purposes. Cellular telephones being an important source of electromagnetic waves are likely to cause interference in the function of these devices. METHODS A systematic analysis of studies on interaction between ...
