Scope of annex
This annex covers frequency bands and regulatory as well as informative parameters recommended for medical data acquisition applications.
They cover transmission of non-voice data to and from non-implantable medical devices for the purpose of monitoring, diagnosing and treating patients in healthcare facilities or patient's home, as prescribed by duly authorised healthcare professionals, including:
- Ultra-Low Power Wireless Medical Capsule Endoscopy (ULP-WMCE) application designed for use in medical
doctor-patient scenarios with the aim of acquiring images of human digestive tract;
- Medical Body Area Network System (MBANS) for low-power wireless networking of a plurality of body-worn
sensors and/or actuators as well as of a hub device placed on/around the human body.
Active Medical Implants and their associated peripherals are included in Annex 12 of this Recommendation.
| Frequency Band | Power / Magnetic Field | Spectrum access and mitigation requirements | Modulation /occupied bandwidth | ECC/ERC Deliverable | Notes | |
|---|---|---|---|---|---|---|
| a | 430MHz - 440MHz |
-50 dBm/100 kHz max e.r.p. density but not exceeding a total power of -40 dBm/10 MHz (both limits are intended for measurement outside of the patient's body) | No requirement | ≤ 10 MHz | ULP-WMCE | |
| b2 | 2483.5MHz - 2500MHz |
10 mW e.i.r.p. | Adequate spectrum sharing mechanisms (e.g. Listen-Before-Talk and Adaptive Frequency Agility) shall be implemented by the equipment and ≤ 2% duty cycle | ≤ 3 MHz | MBANS, indoor only within the patient’s home. The frequency band is also identified in Annex 12 | |
| b1 | 2483.5MHz - 2500MHz |
1 mW e.i.r.p. | Adequate spectrum sharing mechanisms (e.g. Listen-Before-Talk and Adaptive Frequency Agility) shall be implemented by the equipment and ≤ 10% duty cycle | ≤ 3 MHz | MBANS, indoor only within healthcare facilities. The frequency band is also identified in Annex 12 | |

Frequency issues
Sub-bands b1) and b2):
MBANS equipment shall implement a spectrum access mechanism as described in the applicable harmonised European standard EN 303 203 or an equivalent spectrum access mechanism. Based on the assumptions used in ECC Report 201, the modulation bandwidth for MBANS shall not exceed 3 MHz.
