- | The whole process took a little less than an hour, just using GNU Radio and a HackRF (could have been done with an RTL-SDR device as well. The next steps will be covered in Episode II, where we can try to reproduce this pattern with a transmitter we'll build with GNU Radio. This will also serve as a chance to try something I'd like to call **Full Band Replay Attack**. | + | The whole process took a little less than an hour, just using GNU Radio and a HackRF (could have been done with an RTL-SDR device as well.

- | Instead of trying to find the specific frequency and modulation and to build a transmitter for it, it should be equally feasible to just capture the whole ISM band and try to send it as it was received (replay). This would be a very crude approach requiring almost no knowledge but could be disastrously fast and effective when applied successfully, | + | **Full Band IQ Replay Attack**. |
