v20 v21 6 6 7 7 == Project Objective == 8 Batteryless, ultra-low cost RFID (radio frequency identification tags) tags can serve as additional ultra-low cost antennas; variations of the multipath propagation inside a room offer s impressive information for estimating the number of people and their tracks inside a room; WINLAB techniques, including machine learning, will be tested.8 Batteryless, ultra-low cost RFID (radio frequency identification tags) tags can serve as additional ultra-low cost antennas; variations of the multipath propagation inside a room offer impressive information for estimating the number of people and their tracks inside a room; WINLAB techniques, including machine learning, will be tested. 9 9 10 10 … … 12 12 13 13 ==== WEEK ONE-FOUR ==== 14 For the first few weeks, our group worked solely on the [wiki:pD Plant Doctor] project, also led by our advisor Aggelos Bletsas. 14 For the first few weeks, our group worked solely on the [wiki:pD Plant Doctor] project, also led by our advisor Aggelos Bletsas. Additionally, we examined prior work done by our advisor to [https://ieeexplore.ieee.org/abstract/document/10582592 localize people using RFID tags (1)]. 15 15 16 16 ==== WEEK FIVE ==== … … 19 19 //Progress: // During our first week of work, we put 150 RFID tags along two walls of the WINLAB conference room. Before putting them on, we recorded the [https://docs.google.com/spreadsheets/d/1daMvb9Ci_dN-KZEvOz5IOwuJlokXugWA9UsHR1Zu1xM/edit?usp=sharing distinct EPC] (electronic product code) of each tag. We spaced the tags 16cm apart to minimize any interference from multiple tags based on their wavelength. We placed these tags in rows around 4 to 5 feet off the ground. 20 20 21 [[Image(Week 5_1.jpg, 450px)]] [[Image(Week 5_2.jpg, 450px)]]21 [[Image(Week 5_1.jpg, 550px)]] [[Image(Week 5_2.jpg, 550px)]] 22 22 23 23 … … 38 38 [https://docs.google.com/presentation/d/1HmM73QaN0rC-FQ9eomNmFzX3bV5ZxUyMjUdE_epnreo/edit?usp=share_link Week 8 Presentation]\\ 39 39 //Progress: // Adapted the existing code to adhere to FCC guidelines regarding frequency usage. Additionally, we started working on a 3D mapping system for the tags. 40 41 42 == References == 43 (1) A. Kleniatis, A. Dimitriou and A.
