spectrum Matters (ERM).
Modal verbs terminology
In the present document "should", "should not", "may", "need not", "will", "will not", "can" and "cannot" are to be

Introduction
The present document includes necessary information to support the co-operation under the MoU between ETSI and the
Electronic Communications Committee (ECC) of the European Conference of Post and Telecommunications
Administrations (CEPT).
The present document covers the request for harmonised spectrum for sensor or radiodetermination applications using
UWB technology within the frequency range 120 GHz to 260 GHz. Communications applications or hybrid
applications as a combination of sensor and communications applications are not treated within the scope of the present
document.
A need for additional spectrum allocations for UWB radiodetermination devices was identified in order to cover
measurement tasks which cannot be conducted adequately at the moment due to the limited bandwidth in the existing
frequency allocations in the bands 122 GHz - 123 GHz and 244 GHz - 246 GHz although the UWB technology is
already available to do so. Therefore a lot of applications with their market potential could be identified and
summarized.
The intention of the production of the present document is to create a basis for the industry to facilitate the market
launch of new innovative and useful radio products while avoiding any harmful interference with other radio services
and equipment.
The present document was developed by ERM TGUWB. The information in it has not yet undergone coordination by
ERM. It contains preliminary information.

3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 303 883 [i.12], ETSI TS 103 361 [i.4] and the
following apply:
Activity Factor (AF): activity factor of a radiodetermination device is usually defined as the ratio of active
measurement periods t (bursts, sweeps, scans) within the overall repetitive measurement cycle T
meas meas_cycle
Adaptive Power Control (APC): adaptive power control is an automatic mechanism to regulate the transmitter power
NOTE: It is controlled by the received power within the total receiver bandwidth.
blocking distance: blocking distance is the minimum distance from the target to the antenna of a distance measurement
Radar (DMR) sensor which is at least necessary in order to guarantee a reliable measurement
NOTE: If the distance to the target falls below the blocking distance, the measurement may fail because the
sensor is less sensitive or "blind" at closer ranges.
Duty Cycle (DC): product of the pulse repetition frequency (PRF) and the pulse duration t
pulse
Equivalent isotropically radiated power (e.i.r.p.): e.i.r.p. is conventionally the product of "power fed into the
antenna" and "antenna gain related to the isotropic radiator"
Frequency Modulated Continuous Wave (FMCW): modulation scheme which is based on a periodically linear
frequency sweep of the transmit signal.
NOTE 1: For distance measurement sensors often a sawtooth or a triangular modulation scheme is used. By mixing
the current transmit signal with the reflected signal the round trip time of the individual echoes and thus
the distance of the different targets can be determined.
NOTE 2: Although the instantaneous bandwidth of a FMCW Radar is close to zero the recorded power versus time
variation results in a wideband spectrum which is clearly not pulsed.
Stepped Frequency Continuous Wave (SFCW): in contrast to the FMCW principle the transmit frequency in an
SFCW modulation scheme is not swept in a linear manner but rather in a stepped way with defined frequency
increments and with a certain dwell time on each individual frequency step
NOTE: Although the instantaneous bandwidth of an SFCW Radar is close to zero the recorded power versus time
variation results in a wideband spectrum which is clearly not pulsed.
3.2 Symbols
For the purposes of the present document, the following symbols apply:
f lowest frequency of the operating bandwidth

H

4.1 Statements by ETSI Members
No statements or comments have been issued by ETSI members.
5 Presentation of the system and technology
5.1 Use cases for future sensor systems
5.1.0 General
Microwaves travel at the speed of light and this speed is essentially constant under a variety of different environmental
conditions. This makes the use of microwaves a very robust measuring principle which is preferred when high accuracy
is required and environmental conditions, such as temperature, pressure, etc., may vary.
ETSI

---------------------- Page: 9 ----------------------
10 ETSI TR 103 498 V1.1.1 (2019-02)
Some of the main advantages of microwave technology for all kinds of sensors are therefore:
• high measurement accuracy;
• high repeatability;
• robust measuring performance in a variety of environmental- and process conditions;
• high reliability;
• minimum or even no maintenance requirements and wear as a result of no moving parts;
• easy installation;
• non-contact measuring principle provides a high independency of ambient conditions or process properties;
• superior long-term stability resulting from self-calibration mechanisms since devices have always stable
internal references which are independent of temperature or humidity;
• efficient handling of many devices due to the support of different interfaces;
• the antenna or the radome is usually very robust against contamination with dust, dirt or other adverse
environmental influences.
All these factors combined pr
