Recently, RSS based gesture detection using Wi-Fi signal has attracted considerable attention. UWB technology offers more features for gesture detection in indoor environments, which can be applied to medical applications to enhance its accuracy, agility and functionality. In this paper, we compare the gesture detection using Wi-Fi signal RSS and gesture detection using various characteristics of...
The fast deployment of constantly higher speed wireless connectivity for mobile users has lead to a situation where the development of electronics and the battery capacities have not been able to keep up. This has lead to a situation where the batteries of mobile devices run out very quickly when for example enjoying web content. We can enable longer battery life by lowering the QoE by moving to for...
Mobile devices people carry in their pockets every day can use various means to connect to data services all around the Internet, e.g., 2G, 3G and WLAN. This has been an important development towards an easily accessible and always-on the Internet. While radio connectivity, bits rates in particular, has developed tremendously during the recent years, battery technology and electronics has not. Thus,...
The development of ICT following Moore's Law has resulted in a situation where mobile users are able to make use of a wealth of versatile services. Yet, battery and electronics technology has not followed this development as well, which has resulted in a situation where a mobile user's battery can only enable a few hours of active use. Therefore, we need to focus increasingly on energy efficient wireless...
This paper presents two fully integrated transmitters with embedded antennas to demonstrate on-wafer wireless testing for the first time. The proposed transmitters are intended to not only replace the I/O pins during manufacturing testing but also to serve as process monitoring circuits. The first RF transmitter, operating at 5.5 GHz, utilizes a current-reuse LC oscillator to minimize complexity and...
