430-440 MHz Medical Capsule Endoscopy Application

The CEPT ECC have published a report titled 'Coexistence of Wideband Ultra-Low Power Wireless Medical Capsule Endoscopy Application operating in the frequency band 430-440 MHz' 
The CEPT Electronic Communications Committee approved ECC Report 267 on September 29, 2017.
The report was prepared by the ECC Working Group Spectrum Engineering (WG SE) in order to consider the ETSI System Reference Document TR 103 451 [1], which requested regulatory action to allow spectrum access for a new generation of professional medical Short Range Device (SRD) application termed Ultra-Low Power Wireless Medical Capsule Endoscopy (WMCE) and designed to be operated in 430-440 MHz.
The WMCE application is designed for professional medical use, to provide a convenient tool for diagnosis and treatment of human gastrointestinal (digestive) tract diseases. Its main benefit compared with endoscopy tools traditionally used for this purpose is to offer an option of non-painful and non-invasive procedure with very low risk of bleeding or other side effects. WMCE application consists of two elements:

  • a disposable miniature optical imaging camera implemented in the shape of a capsule - Capsule Camera (CCam), which is swallowed by the patient and transmits imaging data;
  • a wearable Data Recorder (DR) placed on the patient to receive and store the imaging data transmitted by CCam.

The report notes there is a marginal risk of interference into DR receivers in case they happen to operate in close proximity to high power stations using the same band, such as Amateur Radio or radiolocation.
