The proposed system enables new entertaining applications by creating the illusion (for a human observer) that both transmitting and receiving LEDs are always switched on.
We present and evaluate a software-based VLC physical layer and a VLC medium access control layer that retain the simplicity of the LED-to-LED approach. The design satisfies the requirement that LEDs should always be perceived as on with constant brightness.
A novel approach for pairing RFID-enabled devices is introduced and evaluated in this work.
This poster investigates the use of a phase-based, Dual-Frequency Continuous-Wave (DFCW) and Continuous- Wave (CW) composite radar for RF backscatter ranging.
We propose a composite Dual-Frequency Continuous-Wave and Continuous- Wave (DFCW/CW) radar system for localization of backscatter RF tags.
Delay-tolerant networks can complement cellular networks to address today's growth in demand for wireless data. We are interested in delay-tolerant networks for reaching out into underserved regions in growing economies, when distributing media and videos from cities to rural areas.
Measurements of the magnetoquasistatic fields generated from a magnetic dipole (an electrically small current loop) located above the earth are presented and compared with calculations using complex image theory.
Magnetoquasistatic position tracking has been shown to be an excellent technique to measure distances between an emitting and receiving loop for distances up to 50 m along a direction perpendicular to the surface normal of the loops .
In this poster we present a wireless position tracking approach using magnetoquasistatic fields and show that it is an excellent technique for locating an active RFID tag.
Two-dimensional (2-D) measurements of the magnetoquasistatic fields generated from a magnetic dipole (an electrically small current loop) located above the earth are compared to calculations using complex image theory.
