Patent ID: 8923967

Claim:
A bio-medical communication system comprises: a bio-medical unit implantable in, or affixable to, a host body, the bio-medical communication system comprising: a bio-medical unit comprising: a power harvesting module operable to produce a supply voltage from a received electromagnetic power signal generated by an electromagnetic device; a communication module powered by the supply voltage, wherein the communication module is operable to wirelessly communicate at least one of an upstream data signal and a downstream data signal; and a functional module operable to: perform a bio-medical function to produce upstream data of the upstream data signal; and process downstream data of the downstream data signal; and a communication device operable to: set-up a communication with the communication module of the bio-medical unit, wherein setting-up the communication includes sending a signal to the electromagnetic device to request the electromagnetic device to generate the electromagnetic power signal; wirelessly communicate the at least one of upstream data signal and downstream data signal with the bio-medical unit; convert at least one of: the upstream data signal into an upstream wide area network (WAN) signal; and a downstream WAN signal into the downstream data signal; and transmit or receive at least one of the upstream and downstream WAN signals.
