  1. ITU Seminar "Economic aspects of national radio frequency spectrum management” Kyiv, Ukraine, 03-05 July 2007 UWB Regulations Le Devendec Marc, ERO

  2. What is UWB? • Regulatory Framework • Regulation in the World • CEPT: • SRR at 24 GHz • UWB Systems below 10.6 GHz • Next?

  3. 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. Ultra Wide Band???

  4. Communication devices (Wireless USB) Ultra Wide Band Applications • 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....

  7. Problem… ISM band: 24.05-24.25 GHz 5 GHz Proliferation of devices Band used by EESS, FS, RAS... Compatibility??

  8. Definition of UWB??? Service status Regulatory Framework for UWB • 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… »

  9. Development of a Regulatory Framework • 1990s: UWB became practical • 1999: First UWB systems available • 2000: US inquiry – need to protect GPS • 2002: FCC limits Vehicular radar systems • Around 24 GHz: RAS, EESS, FS…

  10. FCC limits: Medical Imaging System UMTS EESS *Operation is limited to law enforcement, fire and rescue organizations, scientific research institutions, commercial mining companies, licensed health care practitioners, and construction companies.

  11. FCC limits: Communications Indoor... FSS (3.4-4.2 GHz) EESS * Equipment must be designed to ensure that operation can only occur indoors or it must consist of hand-held devices that may be employed for such activities as peer-to-peer operation. Not acceptable for CEPT!

  12. ITU-R: Task Group 1/8 (TG 1/8) in 2002 • Define a Harmonised Regulatory Approach: • Question 226/1: Spectrum management framework related to the introduction of UWB devices • Question 227/1: Compatibility between UWB devices and radiocommunication services 2006: ITU-R Rec • SM.1744 • SM.1745 • SM.1746 • SM.1747 ITU-R Rep • SM.2057 US (FCC) CEPT (TG3) Japan Others...

  13. 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. TG 1/8: Outputs • Measurement Techniques of UWB emissions • Characteristics of UWB Devices • Spectrum Management Framework for UWB • Compatibility between UWB systems and Other Services

  14. USA/FCC See also IEEE 802.15

  15. Singapore Authorised technical trials for UWB in a specific geographical location (UWB friendly zone) Emissions limits from 2.2 GHz to 10.6 GHz 6 dB above FCC limit

  16. Hong Kong • 3.1 – 10.6 GHz band open for UWB trials • Eirp density limits 8 dB above the FCC limit • 3.1 – 10.6 GHz band is assigned for indoor trials • 4.2 – 10.6 GHz band is assigned for outdoor trials Japan • 3.4 – 4.8 GHz • -41.3 dBm/MHz with Detect And Avoid (DAA) or • -70dBm/MHz without DAA • 4.2 – 4.8 GHz: interim basis (2009) without restriction • 4.8 – 7.25 GHz: 29 dB more stringent than FCC limit • 7.25 – 10.25 GHz: same limit as FCC • SRR 24 GHz ongoing Ongoing in China, South Korea...

  17. Australia • 2004: • April: Interim licence for an UWB ground penetrating radar • December: Extended interim licensing for other devices • 2006: Licence for UWB in the frequency range 22-26.5 GHz New- Zealand • 2005: • Licences to low potential to cause inteference, on a case-by-case basis • In addition, trials ongoing • SRR: General User Licence, on a ”non interference, non protected” basis, until June 2013
