3d Signal Strength Mapping Of 2.4ghz Wifi Networks, Brett D. Glidden Dec 2018

3d Signal Strength Mapping Of 2.4ghz Wifi Networks, Brett D. Glidden

Electrical Engineering

Many commercial businesses operate out of multi-story office buildings. These companies often use many Wi-Fi access points to set up their own wireless network. IT personnel determine proper Wi-Fi access point placement using Wi-Fi strength maps. Conventional Wi-Fi strength maps only provide a two-dimensional view representing the wireless access point's effective range. The signal quality and strength measurements do not include changing vertical elevation. Efficient network layout in a multi-story building requires a system calculating signal quality metrics in three dimensions.

This project involves designing and prototyping a system to achieve 2.4GHz Wi-Fi signal quality measurements in a three-dimensional reference …


High-Bandwidth Iop Sensing Backscatter Transceiver, Mark Manuel Jun 2018

High-Bandwidth Iop Sensing Backscatter Transceiver, Mark Manuel

Electrical Engineering

This document describes the design and build of a mobile phone attachment that communicates with an ASIC embedded smart contact lens. The portable device enables patients and clinicians to conveniently and instantaneously measure intraocular pressure (IOP). The device replaces bulky and expensive benchtop RF synthesizer and signal analyzer machines required for communication to the smart contact lens into a portable and convenient device. The transceiver transmits VHF ISM band radio and can capture reflected backscatter On-Off-Keying modulated message signals at bandwidths from DC to 130MHz.
