The present document contains requirements to demonstrate that Ultra Low Power Active Medical Implants
(ULP-AMI) and Peripherals (ULP-AMI-P) used in a Medical Implant Communications Service (MICS) "… shall be so
constructed that it both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful

Medical Implant Communication Link (MICL): collection of transmissions that may or may not be continuous, between ULP-AMIs and ULP-AMI-Ps, including programmer/controllers, transferring patient related information in a communications service Medical Implant Communications System (MICS): system specifically for the purpose of providing non-voice digital communications between one or several ULP-AMI and one ULP-AMI-P or between ULP-AMI Medical Implant Communications System (MICS) session: collection of transmissions that may or may not be continuous, between co-operating ULP-AMI and ULP-AMI-P medical implant event: occurrence or the lack of an occurrence recognized by a medical implant device or duly authorized health care professional that requires the immediate transmission of data from a medical implant transmitter in order to protect the safety of the person in whom the medical implant transmitter has been placed NOTE: It is not permitted that this is the only mechanism a medical implant transmitter can use to access spectrum. monitoring system: circuitry in an ULP-AMI and/or ULP-AMI-P that assures conformity with the spectrum access protocol requirements based on Listen before Talk, Adaptive Frequency Agility and selection of the least interfered channel for operation (LIC) radiated measurements: measurements, which involve the absolute measurement of a radiated field spurious domain radiations from the receiver: components at any frequency, generated and radiated by active receiver circuitry and the antenna NOTE: See clause 4.2.2.1.1. talk mode: transmission of intentional radiation by a transmitter telecommand: use of radio communication for the transmission of signals to initiate, modify or terminate functions of equipment at a distance telemetry: use of radio communication for indicating or recording data at a distance time-critical data: data which if not transferred immediately will result in compromising the health and/or safety of the patient Ultra Low Power Active Medical Implant (ULP-AMI): radio part of an AIMD Ultra Low Power Active Medical Implant Peripheral (ULP-AMI-P) device: the radio part of equipment outside the human body that communicates with an ULP-AMI to establish a MICL unwanted emissions: emissions in the spurious domain and out of band domain NOTE: See clause 4.2.1.4.1. 3.2 Symbols For the purposes of the present document, the following symbols apply: B bandwidth dB decibel E electrical field strength Eo reference electrical field strength (see annex B) f frequency fc channel centre frequency SIST EN 301 839 V2.1.1:2016
