Medical implant communications service

Three months later, Jane is taking a walk in the Central Park on a Sunday afternoon. A sudden large noise startles her. The microbot implanted in Jane s chest detects irregular heartbeats and activates the automatic implantable cardioverter defibrillator, and makes an emergency call (911) via the Medical Implant Communication Service (MICS) interface and cellular communication. 

Most manufacturers in the United States use the medical implant communications service (MICS) band, established since 1999. This band sets aside the 402-405 MHz frequency range, a range that has reasonable signal-propagation characteristics in the human body. The increase in wireless and network connectivity has led to concerns over data privacy and security, and calls to the FDA to establish a policy in this area (Maisel and Kohno 2010). 

For implantable devices, available transmission frequencies compose the medical implant communication services (MICS) band between 402 and 405 MHz, ultrahigh frequency (UHF) 433 MHz or lower-frequency bands including very-high frequency...
