(Main)Electromagnetic compatibility and Radio spectrum Matters (ERM) - Short Range Devices (SRD) - Ultra Low Power Active Medical Implants (ULP-AMI) and Peripherals (ULP-AMI-P) operating in the frequency range 402 MHz to 405 MHz - Part 1: Technical characteristics and test methods
Electromagnetic compatibility and Radio spectrum Matters (ERM) - Short Range Devices (SRD) - Ultra Low Power Active Medical Implants (ULP-AMI) and Peripherals (ULP-AMI-P) operating in the frequency range 402 MHz to 405 MHz - Part 1: Technical characteristics and test methods
The present document covers, for Ultra Low Power Active Medical Implants (ULP-AMI) and Peripherals (ULP-AMI-P) used in a Medical Implant Communications Service (MICS), the required characteristics considered necessary to efficiently use the available spectrum and serve the interests of implant users. The specifications contained in the present document were developed to ensure that the health and safety of the patients that are using this equipment under the direction of medical practitioners is protected. Of particular importance is the inclusion of spectrum monitoring and access requirements (listen before talk protocol) designed to significantly reduce any interference potential between MICS systems operating in the band or between a MICS system and the primary users of the band. Also included in the present document is the capability of Low Duty Cycle/Low Power Access in the 403,5 MHz to 403,8 MHz frequency band. An AIMD is regulated under the AIMD Directive 90/385/EEC [i.10]: radio parts contained therein (referred to herein as ULP-AMI and ULP-AMI-P for peripheral devices) are regulated under the Directive 1999/5/EC [i.1] (R&TTE Directive). It is intended that the present document applies to operation in the band 402 MHz to 405 MHz only and that devices that can also operate in spectrum outside this band also meet any applicable requirements for operation in such bands. The present document contains the technical characteristics for ULP-AMI radio equipment which is also addressed by CEPT/ERC/REC 70-03 [i.2] and annex 12 to that document. It does not necessarily include all the characteristics, which may be required by a user, nor does it necessarily represent the optimum performance achievable. It applies to ULP-AMI devices and accessories operating in the band 402 MHz to 405 MHz:
- for telecommand and telemetry to/from an AIMD in a patient's body to an ULP-AMI-P; or
- for telecommand and telemetry to/from an AIMD to another AIMD within the human body;
- with or without an integral antenna; and/or
- with an antenna connection provided only for the purpose of connecting an external dedicated antenna. The present document covers requirements for radiated emissions above 25 MHz.

Introduction ULP-AMI/ULP-AMI-P equipment in the MICS service is a unique new technology, available world wide in the medical field, that will provide high speed communications capability between individuals with AIMDs and medical practitioners engaged in utilizing these AIMDs for the purposes of diagnosing and delivering therapy to individuals with various illnesses. Equipment in the MICS service consists of active medical implants that communicate to other active medical implants and/or to ULP-AMI-P as e.g. external programmer/control transmitters. The present document includes methods of measurement for Ultra Low Power Active Medical Implants (ULP-AMI) and Peripherals (ULP-AMI-P), fitted with antenna connector and/or integral antenna. Equipment designed for use with an integral antenna may be supplied with a temporary or permanent internal connector for the purpose of testing, providing the characteristics being measured are not expected to be affected. If equipment, which is available on the market, is required to be checked it should be tested in accordance with the methods of measurement specified in the present document. Clauses 1 through 3 provide a general description on the types of equipment covered by the present document and the definitions, symbols and abbreviations used. SIST EN 301 839-1 V1.3.1:2009

Introduction
ULP-AMI/ULP-AMI-P equipment in the MICS service is a unique new technology, available world wide in the
medical field, that will provide high speed communications capability between individuals with AIMDs and medical
practitioners engaged in utilizing these AIMDs for the purposes of diagnosing and delivering therapy to individuals
with various illnesses. Equipment in the MICS service consists of active medical implants that communicate to other
active medical implants and/or to ULP-AMI-P as e.g. external programmer/control transmitters.
The present document includes methods of measurement for Ultra Low Power Active Medical Implants (ULP-AMI)
and Peripherals (ULP-AMI-P), fitted with antenna connector and/or integral antenna. Equipment designed for use with
an integral antenna may be supplied with a temporary or permanent internal connector for the purpose of testing,
providing the characteristics being measured are not expected to be affected.
If equipment, which is available on the market, is required to be checked it should be tested in accordance with the
methods of measurement specified in the present document.
Clauses 1 through 3 provide a general description on the types of equipment covered by the present document and the
definitions, symbols and abbreviations used.

Clause 4 provides a guide to requirements, the number of samples required in order that tests may be carried out and
any markings on the equipment that the provider has to supply.
Clauses 5 and 6 provide general test conditions to be used.
Clause 7 gives the maximum measurement uncertainty values.
Clauses 8, 9 and 10 specify spectrum utilization parameters and the measurement methods that are required for the
protection of the spectrum and patient. Clause 10 describes channel access requirements and methods. In particular
clause 10.1 describes the monitoring system performance specifications that have been chosen to minimize harmful
interference to other equipment or services, reduce the potential for disturbance to this equipment from ambient sources
or other medical device users in the band and provide a high degree of link reliability in the interest of the patient.
Annex A (normative) provides specifications conc

Introduction
ULP-AMI/ULP-AMI-P equipment in the MICS service is a unique new technology, available world wide in the
medical field, that will provide high speed communications capability between individuals with AIMDs and medical
practitioners engaged in utilizing these AIMDs for the purposes of diagnosing and delivering therapy to individuals
with various illnesses. Equipment in the MICS service consists of active medical implants that communicate to other
active medical implants and/or to ULP-AMI-P as e.g. external programmer/control transmitters.
The present document includes methods of measurement for Ultra Low Power Active Medical Implants (ULP-AMI)
and Peripherals (ULP-AMI-P), fitted with antenna connector and/or integral antenna. Equipment designed for use with
an integral antenna may be supplied with a temporary or permanent internal connector for the purpose of testing,
providing the characteristics being measured are not expected to be affected.
If equipment, which is available on the market, is required to be checked it should be tested in accordance with the
methods of measurement specified in the present document.
Clauses 1 through 3 provide a general description on the types of equipment covered by the present document and the
definitions, symbols and abbreviations used.

Clause 4 provides a guide to requirements, the number of samples required in order that tests may be carried out and
any markings on the equipment that the provider has to supply.
Clauses 5 and 6 provide general test conditions to be used.
Clause 7 gives the maximum measurement uncertainty values.
Clauses 8, 9 and 10 specify spectrum utilization parameters and the measurement methods that are required for the
protection of the spectrum and patient. Clause 10 describes channel access requirements and methods. In particular
clause 10.1 describes the monitoring system performance specifications that have be
