An IoT Wearable Communication Prototype Tested in Indoor and Outdoor Environments

The fast adaptation of wearable communication (WC) technology to be applied in the broad fields has exhibited the incredible trend improvement for the last decade. In this research project, a typical WC 2.4 GHz prototype was developed and practically examined. This wearable device is initially designed for transferring two kinds of data, i.e. voice data and video streaming within the indoor and outdoor environments. However, the current WC system only provides the functionality of video and pictures streaming. The sensed objects or locations captured using the wearable device placed on human body will be continuously transferred via the access point and immediately broadcasted to the registered server or the permitted receiver station. The first trial testing of the fabricated WC peripheral has demonstrated the excellent data transmission performed on those two different environments. The maximum reliable communication range between the wearable device and the access point that could be maintained for both indoor and outdoor testing was approximately 17 meters. Beyond that communication range, the transmission quality degraded and connection failure was often occurred. The measured power level received at this maximum distance is approximately - 90 dBm. Various specific applications in the modern societies including smart textiles, smart sports monitoring and assessment, e-Health and so on are highly possible to implement by adopting the current scanning and monitoring wearable device.
