WPT applications operating in various frequency ranges will be considered at the studies.
The first studies will focus on Wireless Power Transmission (WPT) systems for Electric Vehicles (EV) operating in the frequency band 79 - 90 kHz.
These studies will support the work of CEPT CPG on its studies in relation to WRC-19 Agenda item 9.1, Issue 9.1.6.
Other types of WPT applications and other frequency ranges will be considered at the second step of studies.
The study will cover generic WPT systems/devices operating in various frequency ranges e.g. 19-21 kHz, 58-62 kHz,79-90 kHz and 100-300 kHz.
ETSI developed ands ent to ECC a second SRdoc ("ERM System Reference document (SRdoc); Wireless Power Transmission (WPT) systems for WPT operating below 30 MHz, TR 103 493)dealing with all kinds of WPT systems other than WPT-EV. This study could support the ITU-R WP 1A/WP1B work on WPT applications and frequency ranges (Question ITU-R 210-3/1).
ECC Report 289 on WPT-EV in the 79-90 kHz band is published. A second ECC Report is to be developed on WPT applications.
The use of high power SRDs in the first RFID interrogator channel requires additional study, to consider whether NBN SRD can be operated at 500 mW (with APC) and duty cycle of 2.5% (with NAPs at 10% duty cycle). If this is not feasible, other possibilities such as the reduction in transmit power necessary for coexistence could be studied.
Conduct studies with regard to the intended update of the existing UWB regulatory framework based on the SRdocs TR103 313 and TR 103 314 to answer the permanent EC mandate on UWB.
- multi-carrier DL UNB (1kHz BW), with and without APC, on multiple RFIDinterrogator channels in 865-868 MHz and in the interrogator channels 917.5 and918.7 MHz.
- optional LBT in the DL, instead of APC.
- DC potentially defined in other time interval than one hour for ULtransmissions by 25 mW devices, only in 917.4-919.4 MHz, e.g. for tracking ofstolen vehicles.
- UL transmissions should be taken into account. They are not linked toRFID interrogator channels and use the generic 25 mW entries under REC 70-03Annex 1.
The study will assess the possibility of having mobile NAP with a DC of either 2.8% or up to 10% in the band 863-868 MHz only. A different duty cycle template may be considered.
In the band 915-921 MHz, the requirement for fixed NAP needs to be maintained.
Note: The use of all or part of the bands 870-874.4MHz, 915-919.4 MHz may not be available in some European countries due to theuse of all or part of these sub-bands for defence/ governmental systems.
UL transmissions will also be taken into account.
Feasibility of spectrum sharing by High-Definition Ground Based Synthetic Aperture Radar (HD-GBSAR) application using 1 GHz bandwidth within 74 - 81 GHz frequency range and existing services and applications.
o The studies can also include other types of UWB technology based sensors which are not described in ETSI TR 103 498. Such information may be considered based onc ontributions within the process. One example is automotive radars.
