ITU WORKSHOP on SHORT RANGE DEVICES (SRDs) AND ULTRA WIDE BAND (UWB)
(Geneva, 3 June 2014*)
* in conjunction with the June 2014 block of meetings of ITU-R Study Group 1
Dr. Michael Mahler
"European UWB activities and
worldwide UWB harmonization
needs"
ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva 2
UWB applications in ECC/ETSI
Generic UWB indoor (fixed use) Location
Tracking (in- & outdoor + fixed)
Automotive and railway vehicles (in & outside)
(Tank) Level Probing radar
(on-board) Aircraft use
Automotive radar (ShortRangeRadar)
Ground & Wall probing radar
Building Material Analysis
Object Discrimination for Power tools Mobile Device
in- & outdoor
UWB? SRDs in 122 – 123GHz 507 – 64GHz

Example: mean power spectrum mask, average over 1ms, with / without mitigation
Note: peak limit: 0dBm/50MHz
ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva 4
UWB interference potential
conventional narrow-band system (+20dBm)
UWB signal (-41.3dBm/MHz)
Noise / EMC emissions
ETSI covers this situation with TS 102 883
UWB has lower PSD than an unintentional emission
Notes: - Details for different UWB signals are given in draft ETSI TR 103 181-1 - TS 102 883: Ultra Wide Band (UWB); Measurement Techniques

UWB framework in ECC/EC/ETSI-1
LT: Location Tracking
BMA: Building Material Analysis
Below 10GHz

UWB framework in ECC/EC/ETSI-2
Below 10GHz and specific
ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva 7
UWB framework in ECC/EC/ETSI-3
Vehicular / range radar applications
ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva 8
Example: comparison FCC versus CEPT/ECC
Note: For details, see Draft ETSI TR 103 181-1 & -3
ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva 9
Some UWB ranges in the world
Note: Part out of Draft ETSI TR 103 181-3
ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva 10
no certification process defined in many countries if defined, rules vary for:
- frequency ranges - application restrictions (e.g. vehicle, tracking, medical…) - user restrictions (e.g. public, professional, government,..) - environment restrictions (indoor & outdoor) - mitigation techniques - signal definitions
- conformance testing procedure
minimum BW requirement
modulation requirement (on/off) during “test”
open issues for harmonization
ITU Workshop on Short Range Devices (SRDs) and Ultra Wide Band (UWB), 3 June 2014, Geneva 11
planed till the end of 2014:
finalization of TR 103 181-1 (UWB signals - ECC/EC regulation)
finalization of TR 103 181-3 (UWB situation worldwide)
finalization of TS 102 883 (UWB measurement for LDC, “slow” signals)
stable Draft EN 302 065-4 (BMA and ODC)
validation results (TR/TS work) and decision on: necessary amendments in ETSI standards amendments to the existing or new regulations ? new work items for new applications / Use-cases ?
e.g. medical, assisted healthcare, object identification, material investigation, outdoor use,..
Next ETSI TC ERM/TG UWB meetings: - 9th/10th September 2014 - 12th/13th November 2014
Next actions in ETSI
