Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio
spectrum Matters (ERM).
The present document is part 5 of a multi-part deliverable covering Electromagnetic compatibility and Radio spectrum
Matters (ERM); System Reference Document; Short Range Devices (SRD); Technical characteristics for SRD
equipment using Ultra Wide Band technology (UWB) as identified below:
Part 1: "Building material analysis and classification applications operating in the frequency band from 2,2 GHz
to 8 GHz";
Part 2: "Object Discrimination and Characterization (ODC) applications for power tool devices operating in the
frequency band from 2,2 GHz to 8,5 GHz";
Part 3: "Location tracking applications type 1 operating in the frequency band from 6 GHz to 8,5 GHz for
indoor, portable and mobile outdoor applications";
Part 4: "Object Identification for Surveillance applications operating in the frequency band from 2,2 GHz to
8,5 GHz";
Part 5: "Location tracking applications type 2 operating in the frequency bands from 3,4 GHz to 4,8 GHz
and from 6 GHz to 8,5 GHz for person and object tracking and industrial applications";
Part 6: Void;
Part 7: "Location tracking and sensor applications for automotive and transportation environments operating in
the frequency band from 3,1 GHz to 4,8 GHz and 6 GHz to 9 GHz".
Introduction
The original spectrum request for UWB location tracking applications was covered by part 3 of the present multi-part
deliverable. This original request is now being enhanced by the proposals covered in the present document (part 5).
Therefore, these additional location tracking devices are called type 2. The performance attributes of type 2 devices
include an extended operating range compared with the earlier devices (i.e. type 1) as well as the new frequency range
from 3,4 GHz to 4,8 GHz in addition to the 6 GHz to 8,5 GHz frequency range. It is foreseen that individual licensing
of operators on a site-specific basis will be required.
The total addressable market for type 2 devices is expected to be considerable larger than that under the original
request.

5 Executive summary
5.1 Background information
The present document describes devices using Ultra Wide Band sensor technology for location tracking applications.
In UWB location tracking, small mobile or portable tags, operating as either transmitters or receivers, or both, are
attached to the objects to be located, or are carried by personnel within an area under surveillance. A network of fixed
equipment around the area to be covered, communicate with the tags. By analysing, e.g. the time-of-arrival and/or
angle-of-arrival of the radio signal relative to the known reference stations, the 2D/3D position of the tag can be found.
Typically, the range between a tag and a reference station might be up to 200 m, depending on the area to be observed.
There is evidence that these devices can address versatile industrial requirements in many different markets and
therefore, a socio-economic benefit is given.
It is also possible that such a system will significantly enhance the security and safety of persons monitored in different
applications such as process industries, healthcare, prisons (guards) and lone workers.
A high precision in range measurement is required. This means that the signals necessarily have a very large bandwidth
to provide the required accuracy.
5.2 Market information
The proposed changes will lead to a greater addressable market that also includes new location tracking applications not
considered before.
Detailed market information is given in annex A.
5.3 Technical system description
Small UWB transmitter tags are attached to the objects to be located, or are carried by persons.
A tracking system in the present document can be realized in 3 different ways:
• transmitting tags and receiving fixed equipment (see figure B.1.1)
The UWB signals emitted by a small transmitting tags (carried by persons or attached to the objects to be
located) are detected by a network of receiving fixed equipment placed at known, fixed points around the area
to be covered. By centralized computational means the location of the tags can be determined. Typical
application.
• receiving tags and transmitting fixed equipment (see figure B.1.2)
The UWB signals emitted by a network of transmitting fixed equipment are detected by receiving tags,
which need to have computational means to a detect their own position. Comparable to a GPS system.
• receiving/transmitting tags and receiving/transmitting fixed equipment (see figure B.1.3)
A combination of 1 and 2; both the tag and the fixed equipment can receive and transmit UWB-signals.
ETSI

---------------------- Page: 9 ----------------------
10 ETSI TR 102 495-5 V1.1.1 (2009-01)
The 3D position information / position can be calculated by detecting the UWB signal at a number of receivers (system
set-up 1 or 3) or by detecting different (known) information from different transmitters at one receiver (system
set-up 2 or 3), and analysing the time-of-arrival and/or angle-of-arrival of each radio signal.
In a typical application (system set-up 1), the range between a tag and the fixed equipment might be between 10 m to
200 m, depending on the level of building obstruction between the two.
Since the transmitting tags can only work in combination with the fixed equipment, a useful activity-control strategy
could be to only allow the tags to transmit when they are ordered to do so, or when they receive a "system heartbeat".
For receiving such a command or heartbeat the tags should also have a receiving part (not necessarily on UWB-basis).
Detailed technical information is given in annex B.
5.4 Regulations
5.4.1 Current Regulations
The current regulation (amended ECC/DEC(06)04 [i.5] and ECC/DEC(06)12 [i.6]) excludes fixed outdoor installations.
5.4.2 Radio spectrum requirements and justification
The addition of the lower frequency ranges (i.e. 3,4 GHz to 4,8 GHz) is attractive due to the availability of chipsets
having lower costs and higher antenna efficiency but also because of the lower propagation losses.
Higher emission levels above 6 GHz are necessary for the application scenarios. A detailed description of the emissions
levels is added in clause B.2.2.
The following requirements are proposed for Location Tracking Type 2 applications as shown in table 5.1. These
proposed limits broaden the set of applications which can be addressed by UWB location tracking systems, by
increasing the emissions levels applicable to indoor systems (but with additional duty-cycle restrictions), and by
enabling fixed outdoor systems (with both duty-cycle restrictions and a requirement for individual licensing which
ensures compatibility with existing users of the radio spectrum).

DCR - parameters:
• Ton max ≤ 25 ms
• Toff mean ≥ 38 ms (averaged over 1 sec)
• Σ Toff ≥ 950 ms per second
Peak power limitation
Maximum peak e.i.r.p. (in 50 MHz reference bandwidth, as in ECC/DEC(06)04) [i.5] will be limited to 40 dB higher
than the maximum mean e.i.r.p. spectral density (dBm/MHz) defined in table 6.1 for the various cases.
The proposed individual licensing approach is outlined in clause 5.3.3.
5.4.3 Proposal for individual site specific licensing approach
National Regulatory Authorities (NRAs) may establish individual licensing requirements for the use of the radio
spectrum by LT2 systems with fixed outdoor base stations as part of conditions for the efficient use of radio spectrum.
The purpose of this clause is to provide an example for the establishment of these individual licensing provisions so as
to facilitate the work of both administrations and LT2 professional users in Europe.
It is recommended that the individual licensing regime include the following individual requirements:
• operator registration;
• exact location and information on the area covered (geographical coordinates, radius and indoor or outdoor
operation);
• co-ordination with services potentially affected (e.g. FSS and FS receivers) on the basis of fixed terminal
location, antenna orientation, and possibly frequency;
• the specific combination of mitigating factors to be implemented (e.g. antenna pattern, sub-bands avoided, and
TPC as well as low duty cycle).
If NRAs will require applicants to perform some of the co-ordination tasks, e.g. to identify specific service users to be
assessed, they may need to create a database for LT2 operators to consult.
6 Expected ETSI Actions
It is expected to create a new Harmonized Standard for location tracking type 2 devices. EC Mandate M/407 [i.10] and
[i.12] was accepted by ETSI, and calls for the preparation of Harmonized Standards for UWB.
7 Requested ECC Actions
ECC is requested to study the proposal covered in present document.
It is noted that limits for fixed outdoor unlicensed usage have already been discussed in ECC TG3, but not licensed
usage.
The proposed site-specific individual licensing approach for fixed outdoor transmitters, as well as the proposed DCR for
the frequency band 6 GHz to 8,5 GHz should be taken into account for an amendment of the UWB regulatory
framework
It is recommended that the ECC Decision to be made by mid of 2009 to allow manufacturers sufficient time to have
equipment in the market as of 2010.
