Eliminating network connections with Python
Siddhant Srivastav (~WickedBrat) |
The talk revolves around replacing reliance on normal mobile networks for communication. The tool leverages the LoRa mode of communication over different ranges of radio frequencies and eliminates the use of network connection by forming a mesh network to send/receive messages, media files, and even make calls over your smartphone!
RF signals have been around for a long time now yet it's being used only for restricted communication in closed proximity. Voice communication over walkie-talkies is merely sending data from one node to another, so why can't it be used to send text messages, media files, and make calls using our same old smartphone? Well, this is now possible by connecting our phones with a LoPy device to make use of this mode of communication
Who should attend this talk?
How does the talk proceed
- Talk starts with an overview of the need for the product.
- Then we discuss existing RF mode of communication over walkie-talkies and why can/can't it be used as our solution.
- An overview of LoPy, LoRa, and required hardware is given and the overview of the solution is also discussed here.
- The pros and cons of the solutions are discussed.
- We dive into the code implementation of the tool and how different tasks and media are handled for communication over the existing infrastructure.
- We discuss the successful implementation of the tool and how anyone can replicate the solution and the process to do so.
What can someone get out of this talk?
- An understanding of Python Sockets and networking.
- Forming an alternate and secure mode of communication.
- 0 - 5: Discussion of the need for the product, the current implementation and availability of it as a solution.
- 5 - 7: Brief introduction of LoPy, LoRa, and tools used for the solution.
- 7 - 10: Discussion of solution. Pros and Cons of the solutions.
- 10 - 20: Code implementation of the solution.
- 20 -25: Product milestones and steps to replicate the solution.
- 25 - 30: Q&A
Basic knowledge of Python, JS, and networking should suffice.
Good to have:
- Overview working of TCP protocol and networking.
- Python Sockets
- JS Blobs
