Computer‐mediated, communication‐based foreign language learning programs are showing great promise. Among these, video‐synchronous mediated communication seems to offer an effective way to provide speaking practice, although research findings have been inconclusive. Furthermore, among studies that have documented the effectiveness of video‐mediated communication, it is not clear why some learners...
Providing learners of a foreign language with meaningful opportunities for interactions, specifically with native speakers, is especially challenging for instructors. One way to overcome this obstacle is through video‐synchronous computer‐mediated communication tools such as Skype software. This study reports quantitative and qualitative data from a Skype partner program that emphasized meaningful...
This paper presents the implementation of a 4times4 multiple input multiple output (MIMO) test-bed that is employed for channel characterization using virtual MIMO indoor channel sounding technique. The 4times4 MIMO operates at ISM frequency of 2.45 GHz with 5 MHz of bandwidth using low cost commercially available off-the-shelf components (COTS). The system benefits from direct conversion transceiver...
