3 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide3 Purpose and Contents The purpose of this presentation is to give an overview of the European spectrum regulation for BAN applications Contents –MICS Bands in Europe –ISM Bands in Europe –UWB Bands in Europe –Conclusion

4 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide4 Categorization of BAN links –Some BAN link need high data rates Some medical applications (implanted or wearable) Video links or fast download of big files Links between batteries powered devices Requirement are : Datarate > 10 Mbit/s and low power –Other links require only low data rate Sensors (medical, temperature, movement) or simple interface Embedded into everyday item Requirement are => very low power (energy scavenging) and very simple network subscription / unsubscription High data rate isn't needed

5 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide5 MICS Band in Europe –402 – 405 MHz band has been allocated to Medical implanted Comm System with a 25µW maximal ERP by ERC/DEC 01(17) if compliance with ETSI EN harmonized standard. –The MHz and the MHz frequency bands were selected for the emerging medical implant technologies, using Ultra Low Power – Active Medical Implants (ULP-AMI) and ULP-AMI-P (peripheral devices for ULP-AMI). Band allocation is under investigation

6 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide6 MICS Band in Europe ParameterDescriptionComments Frequency band MHz Radio service according ITU Radio Regulation Mobile Service Application Medical Implants Active medical devices. Channel Spacing25kHzIndividual transmitters may combine adjacent channels for increased bandwidth up to 300 kHz. RF – Powernot defined RF – Radiated Power25 µW e.r.p. Transmit / Receive spacing (Duplex direction) not defined Type(s) of modulationnot defined Duty cycle≤ 100 % Harmonised Standard representing the state of art EN Equipment class according to Commission Decision 2000/299/EC Class 1

7 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide7 MICS Band in Europe Active Implantable Medical Device (AIMD): any active medical device (AMD) which is intended to be totally or partially introduced, surgically or medically, into the human body or by medical intervention into a natural orifice, and which is intended to remain after the procedure

8 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide8 MICS Band in Europe Those bands are reserved only for medical and implanted system. Therefore they can't be used for wearable BAN communications (even for medical applications). It's unsure how "healthcare" applications will be able to use this band. This band is used on a licence-free basis and whithout protection against interference Bandwidth and power are limited.

9 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide9 ISM Band in Europe ISM bands are opened to almost anything (ISM means Industrial, Scientific and Medical) Applications are free for short range device (SRD) but : –Power is limited –Duty cycle can be limited too –There is no protection against interference. CEPT Recommendation ERC/REC 70(03)

10 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide10 ISM Band in Europe Mains sub-GHz bands are : – – MHz : 10 mW if duty cycle is lower than 10% 1mW otherwise –863 – 870 MHz : 25 mW and duty cycle < 0.1% (or LBT) MHz : 25 mW and duty cycle < 1% (or LBT) MHz : 25 mW and duty cycle < 1% (or LBT) MHz : 500 mW and duty cycle < 10% (or LBT) MHz : 5 mW without duty cycle limitation

11 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide11 ISM Band in Europe – MHz : 10 mW widely used & probably overcrowded in a few years (Wifi, ZigBee, Microwave oven, CCTV) Available Worldwide –5725 – 5875 MHz : 25 mW No other restrictions Higher transmit power can be obtained for some application (like wireless data network)

12 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide12 UWB band in Europe UWB was recently approved in Europe by ECC/DEC (06)/04 and ECC/DEC (06)/12 ETSI Harmonized standard are under finalization –TG 31a : communication system –TG 31b : automotive radar –TG 31c : sensor and location / tracking

13 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide13 UWB band in Europe

14 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide14 UWB band in Europe

15 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide15 UWB band in Europe 4.2 to 4.8 GHz band is open with EIRP < dBm/MHz until 31/12/ to 4.8 GHz band is open with EIRP < dBm/MHz with LDC limitations 6 to 8.5 GHz bans is open with EIRP < dBm/MHz With LDC Only before 12/31/ EIRP (dBm /MHz) F (GHz)

16 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide16 UWB band in Europe Only two long term solutions : –Lower UWB Band : need to meet the LDC technical requirement : Ton max = 5 ms Σ Ton < 5% per second and 0.5% per hour We have to see if some of our applications can complies with it –Work above 6 GHz

17 May 16, 2007Doc: IEEE ban Jean Schwoerer (France Telecom R&D) Slide17 Conclusions MICS band can be a good solution –Worldwide availability (to be confirmed for Japan ?) –But applications are very limited and bandwidth is limited –We probably need also a PHY on ISM bands ISM and UWB Bands offers a lot of flexibility –No restrictions on applications –More bandwidth availlable for higher data rate –Sub-GHz ISM bands will be hard to use –2.4 GHz and UWB offers WW compliance
