[TINYMESH] What is “link budget” of a Tinymesh module?

The ‘link budget’ is the difference in dB between your receiver sensitivity and the output of your transmitter, including the loss and/ or gain of your antenna. A low power Tinymesh module has a maximum output power of 10dBm, and an RX sensitivity of -99 dBm at the default RF bitrate for the sub- 1GHz modules, giving a total theoretical link budget of 109 dB. High power modules (27 dBm) will add 17 dB to your link budget for sub- 1GHz modules, for a total link budget of 126 dB at the default 76.8kbps bitrate.
