The purpose of this research is to build an educational prototype for attracting high school seniors and college students to pursue university degrees. The prototype entails demonstrable hardware and software comprising of a set of communication nodes with call priorities, which are used to help educate students on future and practical implications of spectrum sharing. Two objectives are achieved...
In this paper, we are investigating an alternative architecture for the RF transceiver of mobile phones which is capable of supporting the latest features and bands used for LTE. In this work, the duplex filter is replaced by equipping the Rx and Tx branch of the front-end with dedicated antennas. Duplexing is achieved by the less demanding tunable filters and the electromagnetic isolation between...
This paper presents a high-speed multimedia content-downloading system using 60GHz millimeter wave (mmWave) technology. For a cost-effective solution, the system makes use of conventional 802.11 for the interactive controls between an access point and smart mobile devices, handling such services as access point discovery, authentication, mmWave link establishment, beam steering, and lost packet recovery...
Recent demand for multifunctional wireless devices has increased the challenge for the antenna designers, who has to address it by providing small antennas able to operate in multiple communication standards. This paper proposes a new generation of radiating systems capable of providing multi-band operation without the need of including a dedicated antenna. The solution is based on the excitation...
In this publication several near field communication (NFC) based sensor demonstrations and related measurements are discussed. These include basic temperature sensor applications and some more complex scenarios with external sensors and actuators. The reader device can be a commercial NFC enabled mobile phone or specially developed hardware. Based on the experience gathered with demonstrations and...
