Technical Architecture & Overview

HackRF One from Great Scott Gadgets is an open source hardware SDR: a half-duplex transceiver covering 1 MHz to 6 GHz that works with GNU Radio, SDR#, and other SDR software. Source code and hardware design files are published in the project repository. Wireless security work with the device covers signal capture and replay, protocol research, and RF assessment of access control systems.

Targeted Technical Use Cases

RF security research and signal replay across a very wide frequency range on open hardware.

Evaluation & Trade-offs

Core Strengths

  • +Covers 1 MHz to 6 GHz in one device.
  • +Fully open source hardware and software.
  • +Strong community, tutorials, and add-on ecosystem.

Trade-Offs & Limitations

  • -Half-duplex only.
  • -Legal restrictions on transmission vary by jurisdiction and band.

Defensive Security Application

Assessing wireless protocols and verifying replay protections by capturing and retransmitting signals.
