UWB Regulations

What is UWB?

Regulatory Framework

CEPT:

SRR at 24 GHz

UWB Systems below 10.6 GHz Next?

Regulation in the World

Ultra Wide Band???

Ultra-wideband technology (UWB): – Short-range radiocommunication– Transmission of radio-frequency energy spreading over a very

large frequency range– Can provide high data rate (more than 100 Mbits/s) at very low

transmit power.

4



Ultra Wide Band Applications

• Communication devices (Wireless USB)• Penetration capabilities: Radar imaging device used to obtain

images of obstructed objects. This includes in-wall and through-wall detection, ground penetrating radar, construction and home repair imaging, mining, and surveillance devices.

• Vehicular radar device: a radar device mounted on land transportation vehicles to detect the location and movement of persons or objects near a vehicle (road safety)

• Positioning, tracking devices....

Regulatory Framework for UWB

• Definition of UWB???• Service status• ITU RR Article 4.4:Administrations of the Member States shall not assign to a

station any frequency in derogation of either the Table of Frequency Allocations in this Chapter or the other

provisions of these Regulations, except on the express condition that such a station, when using such a frequency assignment, shall not cause harmful

interference to, and shall not claim protection from harmful interference caused by, a station operating in accordance with the provisions of the Constitution, the

Convention and these Regulations.• Application of footnote: 5.340 « all emissions are

prohibited… »

1990s: UWB became practical

1999: First UWB systems available

2000: US inquiry – need to protect GPS

FCC limits: Medical Imaging System

*Operation is limited to law enforcement, fire and rescue organizations, scientific research institutions, commercial mining companies, licensed health care practitioners, and construction companies.

Measurement Techniques of UWB emissions Characteristics of UWB Devices Spectrum Management Framework for UWB Compatibility between UWB systems and Other Services

TG 1/8: Outputs

• Ultra-wideband technology: technology for short-range radiocommunication, involving the intentional generation and transmission of radio-frequency energy that spreads over a very large frequency range, ... Devices using UWB technology typically have intentional radiation from the antenna with either a –10 dB bandwidth of at least 500 MHz or a –10 dB fractional bandwidth greater than 0.2.

• OIS Object Identification for Surveillance - 2.2 GHz to 8.5 GHz (draft EN 302 501)

• LAES Location Application for Emergency Services (TR 102 496)

Others Applications

• Generic Limits too stringent (i.e. for BMA below 4.2 GHz) and do not permit the use of some applications

• Relaxation of the limit + mitigation techniques (LBT, DAA…)

24



Summary

• 24 GHz– Non-interference, non-protected basis– E.i.r.p of -41.3dBm/MHz– Additional limitations to protect passive bands– Move to higher frequencies (79 GHz)

• UWB below 10.6 GHz– Generic Limit– Application-by-Applications approach – Mitigation Techniques

25



Next• SRR Review and Implementation

• ”UWB” in higher frequencies 7GHz aroung 60 GHz

• Agenda Item on UWB for one of the next WRC??

• Developement of Regulation for specific UWB applications (ODC Object Discrimination and Characterization - draft EN 302 498)…

• EC Mandate on 3.1 - 3.4 GHz (-85dBm/MHz) and 8.5 – 9 GHz (-65dBm/MHz)
