Introduction
Ultra Wide Band (UWB) technology enables a new generation of Location Tracking devices and opens new markets
with very different applications. UWB radio location devices with an operating bandwidth of several GHz allow
centimetre-level localization and positioning even in the presence of severe multipath effects caused by walls, furniture
etc.
It is a viable positioning technology that meets industrial requirements in the following markets:
1) Healthcare.
2) Workplace/Smart Office.
3) Public buildings.
4) Security.
5) Defence training.
6) Entertainment.
7) Logistics, warehouses.
8) Manufacturing assembly lines.
9) Road and rail vehicles.
The purpose of producing the present document is to lay a foundation for industry to quickly bring innovative and
useful products to the market while avoiding any harmful interference with other services and equipment.

1 Scope
The present document defines the requirements for radio frequency usage for Ultra Wide Band (UWB) location
tracking devices type 1. These devices are operating in the frequency range from 6 GHz to 8,5 GHz. Operation is
foreseen for indoor, portable and mobile outdoor applications and the operating distance is limited to a maximum of
about 100 metres. It will include applications from all different markets (see list of markets in introduction).
The type 1 equipment complies with the conditions of the amended generic ECC decision [5]. Type 2 is covered in
part 5 of TR 102 495 [9] and corresponds to a future generation of the equipment.
The present document covers ultra-wideband location tracking tags which are attached to people or objects and tags are
tracked using a fixed receiver infrastructure to only receive the UWB emission emitted by the tags. Equipment covered
by the present document is fitted with an integral or dedicated antenna.
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).

4 Executive summary
The present document describes devices using Ultra Wide Band Sensor technology for location tracking applications.
In UWB location tracking, small, mobile tags, operating as either transmitters or receivers, or both, are attached to the
objects to be located, or are carried by personnel. A network of reference stations 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 100 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 health care.
A high precision in range measurement is required. This means that the required signals necessarily demand short pulse
length resulting in a high bandwidth to provide the required accuracy.
