"Establishing A Secure Communication Link" in Patent Application Approval Process (USPTO 20230104064).

The system further includes a second device including second communication circuitry configured for wireless communication according to the first communication protocol having a first range and the second communication protocol having a second range, the second communication protocol different than the first communication protocol and the second range greater than the first range, and second processing circuitry electrically coupled to the second communication circuitry. The first device of claim 1, wherein the first communication protocol includes a magnetic induction communication protocol, a radio frequency (RF) communication protocol, or a tissue conductance communication (TCC) protocol. The first processing circuitry is configured to receive, via the signal reception circuitry, a first signal according to the first communication protocol. "In other examples, a method includes receiving, by signal reception circuitry of a first device configured to receive communications transmitted according to at least a first communication protocol, a first signal according to the first communication protocol.
