Welcome to Network Engineering Stack Exchange
Network Engineering Stack Exchange is a question and answer site for asking questions about professionally managed networks in a business environment. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about network engineering.
We're a little bit different from other sites. Here's how:
Ask questions, get answers, no distractions
This site is all about getting answers. It's not a discussion forum. There's no chit-chat.
Just questions...
...and answers.
Good answers are voted up and rise to the top.
The best answers show up first so that they are always easy to find.
The person who asked can mark one answer as "accepted".
Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.
Using sound waves in layer 1
Is it possible, in theory, to use sound waves as the physical medium to transmit data over a network?
In other words, could you implement layer 1 of the OSI networking model using sound waves or am I totally misunderstanding the physics/networking concepts?

Yes it’s possible. In fact, Amazon Dash buttons use ultrasound as a medium.

It's been done. I used to have a 300-baud acoustic layer 1 device.

Get answers to practical, detailed questions
Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.
Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.
Questions that need improvement may be closed until someone fixes them.
Tags make it easy to find interesting questions
All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.
Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.
