Hamnet70: IP-based Networking on the 70cm Amateur Radio Band

This project seeks to implement a wireless networking system that can transfer Internet Protocol (IP) packets at high speed. In spirit, it is somewhere at the intersection of Packet Radio, Hamnet and Wireless LAN.

Documentation

The documentation is written in AsciiDoc and can be found in the doc directory. It describes the packet formats, used modulation and channel codes, timing and so on.

Implementation

The project is implemented in C and uses the liquid-dsp library for large parts of the signal processing. The whole modulation, synchronization and demodulation process is implemented in software. This allows to use generic SDR hardware to transmit and receive packets. Currently, only the HackRF One is supported.

You can find the code in the impl directory.
