17、Matters (ERM). ETSI ETSI TR 102 434 V1.1.1 (2005-06) 5 1 Scope The present document defines the requirements for radio frequency spectrum usage for single channel ULP - AMI active medical implants and peripherals operating from 403,5 MHz to 403,8 MHz (nominal centre frequency of 403,65 MHz) and havi

18、ng a duty cycle of less than or equal to 0,01 %. The technical characteristics of these devices along with the benefits of this access method are described. A single channel, low duty cycle (less than or equal to 0,01 %) ULP-AMI is proposed as an alternative option to LBT and frequency agility as in

19、terference mitigation technology which ensures the assigned spectrum remains clear and available to all users of the spectrum. This type of operation is limited only to ULP-AMI (implants) and is not permitted for ULP-AMI-P (peripheral equipment). The proposed SRDoc prohibits external device to exter

20、nal device communication. The present document includes necessary information to support the co-operation between ETSI and the Electronic Communications Committee (ECC) of the European Conference of Post and Telecommunications Administrations (CEPT), including: Detailed market information (annex A);

21、 Technical information (annex B); Expected compatibility issues (annex C). It is not proposed to change the current regulations. 2 References For the purposes of this Technical Report (TR) the following references apply: 1 CEPT/ERC Recommendation 70-03: “Relating to the use of Short Range Devices (S

UNQUOTE 4.1.3 Position of Biotronik, St. Jude,

44、Ela Medical, Zarlink and Bolt Consult Biotronik, St. Jude, Ela Medical, Zarlink and Bolt Consult support this SRDoc without any reservation. 4.2 Technical issues ULP - AMI and ULP - AMI - P devices currently provide significant life saving and quality of life benefits for medical patients afflicted

45、with a variety of heart conditions, nerve disorder and other afflictions. The systems operating in the 402 MHz to 405 MHz band consist of devices that are implanted in the body that only communicate with an external peripheral device. Examples of implanted devices are defibrillators, pacemakers, and

46、 various types of nerve stimulators. In current systems typically used in the patients home (“Home Monitoring“) the ULP-AMI device sends data to the ULP - AMI - P device. Patient monitoring is also possible in clinics, hospitals and managed care facilities. In addition, there will be other systems w

47、here data will also be sent from the ULP-AMI-P to the ULP-AMI (e.g. “programming“). The latter systems will typically be used in hospitals and/or doctors office environments. The performance of systems compliant with EN 301 839-1 4 (i.e. those implementing LBT and AFA) may be degraded if the 403,5 M

48、Hz to 403,8 MHz channel is selected as the Least Interfered Channel (LIC). In such a scenario, the communication link may be interrupted by a low duty cycle system that does not implement LBT and AFA. The degradation is minimized if the single channel (403,5 MHz to 403,8 MHz) is excluded from the se

49、t of operating channels for systems compliant with EN 301 839-1 4. Two types of devices are envisioned with the present document: the first is a single frequency transmit-only LDC system, the second is a device that uses LDC to initiate an LBT/AFA session. Single-frequency transmit-only Low Duty Cycle (LDC) systems cannot change frequency to avoid interference from the primary user of the band (Meteorological Aids), multi-user (MICS band devices), or man-made (
