ITU-T Telecommunication standardization - network and service aspects ITU Overview Committed to connecting the world 193 Member States 673 Sector Members 168 Associates 153 Academia ITU-D Promote and assist the extension of ICTs to all the world s inhabitants - narrowing the digital ITU-R divide Global radio spectrum management and radiocommunication standardization
Spectrum Harmonization Objective: Achieving rapid launch of new bands and economies of scale, by aligning national spectrum policies with those recommended internationally Means: Adopting Harmonized Frequency Plans, as defined by ITU-R and regional organizations, to facilitate competition Working in collaboration with regional and international partners to develop coordinated regulatory practices Removing regulatory barriers to free movement and global roaming mobile terminals, short-range devices and similar radio equipment Using the formats and elements of internationally recommended data bases, to facilitate exchange for coordination Using wherever possible, international and regional standards, reflected in the national standards Based on industry standards, including those in ITU-R ITU-T, and possibly adopt them as national standards instead 3
Benefits: Spectrum Harmonization Reduces cost of hardware (cheaper smartphones) Enables global roaming. Reduces the complexity of the radio design. Reduces interference with adjacent services and helps managing cross-border interference. Cost of infrastructure is reduced, benefit passed on to users through a reduced cost of service. Increased access to mobile broadband will increase ICT literacy. Development of relevant mobile applications will add value to users over time.
Spectrum Harmonization Step 1: Harmonizing Band Allocation Updating ITU Radio Regulations (Art. 5): During WRCs Ultimate goal (as possible; RR Rec 34): - PRIMARY basis - Not shared - No footnotes - Common to all Regions Regional consensus previous to WRCs Example: 495-505 KHz situation
Spectrum Harmonization Step 2: Harmonizing Band Plan Regional Standards : To be agreed onto Regional Organizations meetings It would be based on ITU Recommendations and Reports (mainly ITU-R), to keep a global approach. National Standards : In consistency with Regional agreements It would be adopted as national standards Step 3: Deployment Publishing band roll-up roadmaps and milestones; Refarming Licensing Process: networks deploy, service availability Trying to avoid large time difference with region trend

Purpose of ITU WRC: Spectrum Harmonization 1. Create regulatory certainty for a multi-trillion dollars activity that provides radiocommunications-based services to billions of people in all countries worldwide, playing a increasingly important role in the development of our societies 2. Strike the right balance between the spectrum requirements of all radiocommunication services 3. Creating certainty requires consensus in order to achieve stable results on a sustainable use of orbit/spectrum resources 4. Reaching consensus requires time, efforts and patience. 5. This is the price to pay for developing and maintaining a sustainable ecosystem for radiocommunications and avoid massive disruptions.
IMT-2000,, IMT-Advanced, & IMT-2020 All of today s 3G and 4G mobile broadband systems are based on the ITU s IMT standards. IMT provides the global platform on which to build the next generations of mobile broadband connectivity. ITU established the detailed specifications for IMT-2000 and the first 3G deployments commenced around the year 2000. In January 2012, ITU defined the next big leap forward with 4G wireless cellular technology IMT-Advanced and this is now being progressively deployed worldwide. The detailed investigation of the key elements of IMT-2020 is already well underway, once again using the highly successful partnership ITU-R has with the mobile broadband industry and the wide range of stakeholders in the 5G community.

DYNAMIC Dynamic SPECTRUM Spectrum ACCESS, Access, DSA DSA DSA is the real-time adjustment of spectrum utilization in response to changing circumstances and objectives DSA might be performed through radio stations with some degree of intelligence, and capability to interact with spectrum use environment, and adjust its operation in conformity; e.g., Cognitive Radio, Software Radio, Database Radio, Adaptive Coding and Modulation, etc. DSA concept does not depend of the service or station; it can be used indistinctly by licensed (primary/secondary) or unlicensed systems. (and it is used by both)
DYNAMIC Dynamic SPECTRRUM Spectrum ACCESS, Access, DSA DSA The principles of DSA might be theoretical applied in any frequency band; therefore, there is no need to allocate specific frequency bands to DSA, neither to radio stations performing it (cognitive radio, software radio, etc). At WRC-12, it was concluded that: the current framework of Radio Regulations provide sufficient flexibility to enable the use of cognitive radio systems, in accordance with its provisions, recognizing in particular the obligations of administrations in preventing interference (Recommendation 76, WRC-12)
