Electromagnetic compatibility and Radio spectrum Matters (ERM); Short Range Devices (SRD); System Reference Document for inductive Loop - Ultra Low Power Active Medical Implants (ULP- AMI) - systems operating in the frequency bands 9 kHz to 315 kHzThe present document applies to the radio sections of inductive loop Ultra Low Power Active Medical Implants in the field of Short Range Devices (SRDs) transmitters and receiver systems operating on various frequencies within the range of 9 kHz to 315 kHz.

The present document gives guidance on the definition of a transmitter mask for the operating frequencies, analyses and the spectrum requirements for transmission of power and data from/to stationary programmers or mobile neurostimulation systems (pain control) to/from active medical implants.

The present document considers the ERC Report 44, [1] and contains the technical characteristics for radio equipment as given in CEPT/ERC Recommendation 70-03 [2]. Therefore, the frequency range 9 kHz to 135 kHz is already sufficiently regulated for inductive systems in CEPT/ERC Recommendation 70-03 [2]. The necessary operation for the frequency range 135 kHz to 315 kHz is not addressed in CEPT/ERC Recommendation 70-03 [2] and is addressed in the present document.

The spectrum parameters for inductive loop ULP-AMI devices that are the subject of this document are intended to be included as a normative annex in the EN 300 330-2 [3] or in a new European Harmonized Standard. They are submitted for consideration to CEPT/ERC WGSE for compliance studies and in WGFM/SRD MG for inclusion in the CEPT/ERC Recommendation 70-03 [2], annex 12.
