Been saying this for a while but the RF world is wildly under-explored on the consumer side. The military has been doing electronic warfare for ages but it's only now popping up in the consumer industry.<p>An example: all wireless protocols can be trivially jammed by just spamming noise, like anything else, but most can also be smart jammed by various methods: spamming disconnect packets, malformed packets that crash the device, noise jamming very specific parts of various transactions, like the alignment section of OFDM QAM on 4/5G, etc. This means, instead of needing some multiple of the targets transmit power to cover a wide area, you can use as much or less power than the target which is extremely bad from an EW standpoint.<p>We need to build smarter wireless protocols that can both resist casual assholes, but also higher sophistication adversaries up to and probably including nation state actors for the safety of our infrastructure.<p>And yes, that means insulin pumps probably shouldn't have radios in them.
