If my detector responds to a typical 20dBm router from ~6m away, then it should hopefully detect the signal from my device from ~200m away. | |

OOK is modified version of ASK modulation. While in ASK modulation logic-0 is represented by lower amplitude and logic-1 is represented by higher amplitude; in OOK modulation there is no carrier during the transmission of logic zero." [from www.rfwireless-world.com] Most wifi MCUs seem to have a smaller power output than I'm interested in. I also need to be able to toggle the carrier on-off ~100 times per second (to produce the OOK/ASK signal). | |
