Entering 3rd year at The Ohio State University, majoring in Electrical and Computer Engineering with a minor in Latin

+

Intend to be integrated into team environment

Desire to create tool that can be adapted and used in future situations for the team

Project Description

Scope: Using the HP16702B Logic Analysis System and

its Advanced Toolkit Set, a baseband LR-WPAN

decoder will be built. This decoder will be built in layers

(following the OSI-ISO 7-layers recommendations),

enabling the identification of PHY packets, MAC frames,

and NWK frames and their fields.

Project Description (ENGLISH)

Scope: Using the (expensive) logic analysis equipment

that we have not had time to learn yet, design and make

software that will “interpret” the meaning of the messages

that are sent in our wireless sensor network.

The team needs to know if errors in the transmission are from (1) the sending side, (2) the receiving side, or (3) somewhere in between.

The Long Journey

en·gi·neer (n.)

1. One who is trained or professionally engaged in a branch of engineering

2. A person who operates or is in charge of a locomotive

Let’s go on this journey to success together!

Results of My ProjectAllows for more effective testing to make a better quality network for customers

Provides better error data than ever before

Saves engineers valuable time spent either analyzing cryptic data or arguing over code mistakes

My ExperienceFelt A Sense of Dedication to Project In Entire Team

Became Acquainted and Comfortable With Corporate Team-Based Environment

Me, hard at work as a Dell– I mean, Eaton intern

My Experience (cont.)Deep Appreciation For Research-Based Environment

Improved Professional Presentation and Communication Skills Through Team

Formed Strong Relationships with Co-workers

The FuturePersonal Goals

Complete Bachelor’s Degree, Pursue EE Graduate Study, and Eventually Earn M.B.A. (Down the Track)

Team Goals

Build Functional Sensor Network For Lighting Systems and Home Automation
