Introduction
Ultra Wide Band (UWB) radio technology enables a new generation of location tracking and sensor devices and opens
new markets with a variety of innovative applications. UWB radio location and sensor devices with an operating
bandwidth of several hundreds of MHz up to several GHz allow tens of centimetre-level accuracy, real-time localization
and positioning even in the presence of severe multipath effects caused by walls, furniture or any other harsh radio
propagation environments.
It is a viable positioning and sensor technology that meets industrial requirements in the following markets:
1) Healthcare.
2) Workplace/Smart Office.
3) Public buildings.
4) Security.

1 Scope
The present document covers a system description and the corresponding spectrum requirements for devices using
UWB radio technology operating in the frequency range from 3,1 GHz to 4,8 GHz and from 6 GHz to 8,5 GHz which
are in automotive or public transportation environments (e.g. installed in road and rail vehicles).
The operating radio link distance is limited typically to a maximum of about 30 meters, whereby some application
scenarios show challenging operating conditions which impose the requirements stated in the present document.
Some applications described in the present document will enhance the safety of the passengers, but these applications
are not safety critical.
UWB based applications under the scope of the present document typically rely on small, cost and energy effective,
lightweight tags/sensors which are attached inside or outside the vehicle, to objects or parts of the vehicle to be
monitored, or are explicitly carried by passengers. They may also form an integral part of portable electronic equipment
carried by passengers (such as future generation mobile phones equipped with an additional UWB air interface).
They are connected to one or more "reference stations", also in the scope of the present document, placed inside the
vehicle, which collect the data and communicate, when needed, via a UWB signal to the tags/sensors.
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).
• Technical information (annex B).
• Expected compatibility issues (annex C).

5 Executive summary
5.1 Background information
The growing demand for UWB based applications installed in road and rail vehicles covered in the present document
are grouped into three categories according to the commonalities in the spectral usage requirements resulting from
specific application scenarios. All three categories belong to the automotive or public transportation environments.
They are listed in table 1 and shortly summarized in clause 5.2.
Table 1: Overview of location tracking and sensor applications for automotive
and public transportation environments
category application short description frequency
A Location Tracking in Location positioning datagrams are exchanged through one 3,1 GHz to 4,8 GHz,
a public or more of the reference stations mounted inside the vehicle 6,0 GHz to 8,5 GHz
transportation at convenient locations, with mobile tags carried by
environment passengers and/or luggage. The typical range of radio
operation is 1 m to 30 m. Environmental conditions can be
challenging in selected cases. All cases need to be covered
with high reliability.
B Location Tracking in Location tracking datagrams are exchanged between a 3,1 GHz to 4,8 GHz,
the automotive base station located inside the vehicle and corresponding 6,0 GHz to 8,5 GHz
environment mobile tags and/or the vehicle key.
C Sensing in the Telemetry datagrams are exchanged in a vehicle mounted 3,1 GHz to 4,8 GHz,

environment

5.2 Application technical summary and market information
The implementation of new UWB applications in transportation environments requires new spectrum for the defined
categories as further described in the following clauses.
5.2.1 Category A: Location tracking in public transportation (road and rail
vehicles)
In various European countries public transportation network operators are currently looking for Electronic Fare
Management (EFM) systems based on the Be-In-Be-Out (BIBO) principle. Be-In-Be-Out systems determine
automatically if a person is inside a transportation means and are more accepted than any check-in-check-out
technology in public transportation. It is a basic element of future Electronic Fare Management Systems.
BIBO systems can be realized in an optimal way applying UWB radio-based, accurate, real-time, automatic positioning.
Small mobile tags operating as transceivers are attached to the objects to be monitored or are carried by humans in
clothing or inside luggage. A network of reference stations is inside the vehicle and suitably covers the internal area.
The network communicates with the tags. Typically, the range between a tag and a reference station will be from 1 m to
30 m, depending on the public transportation vehicle size and geometry.
ETSI

---------------------- Page: 10 ----------------------
11 ETSI TR 102 495-7 V1.1.1 (2010-03)
By analysing tag-related radio link parameter(s), 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(s) can be found. Data can be transmitted
containing information derived by the tags.
The main application, EFM systems based on the BIBO principle, needs to exchange data telegrams and identify the
location of mobile tag(s) in or around the public transportation vehicles. The base stations (or so called anchor nodes)
are placed inside the vehicle. The system is basically communicating to exchange location datagrams with some minor
additional information for example about tag identity.
Two UWB specific technological options are still being considered: LDR-LT based on pulsed transmissions (similar to
standardized IEEE 802.15.4a [i.7]) as well as HDR-LT based on MB-OFDM (similar to standardized
ECMA-368 [i.8] and ECMA-369 [i.9]). The communication is controlled by a cluster head and thus will happen
subsequently with the tag devices (usually up to several tens of devices per cluster head coverage area). However, this
happens only in certain time intervals and at different geographic positions as the transportation system operates mainly
if customers occupy
