ATDI at DYNAMIC SPECTRUM ALLIANCE Global Summit in Cape Town (9-11 May 2017)


Member of the Dynamic Spectrum Alliance, ATDI took part of the Fifth Meeting DSA Global Summit in Cape Town, 9-11 May 2017, co-hosted by the Independent Communications Authority of South Africa (ICASA).


The summit gathered regulators, ITU, private companies and non-profit organizations project managers to address numerous challenges related to dynamic sharing of Spectrum, a finite resource where innovative approaches, adapted regulations and robust methodologies can turn Spectrum scarcity to Spectrum Abundance (as emphasized by Kalpak Gude, President, DSA in its introduction).

White Space (WS) optimization was one of the main topics discussed and allowed ATDI to come back on its WS Devices Calculation methodology presented in Accra (Ghana) in 2014 during a previous DSA summit. This accurate methodology, integrated in its software suites, aims at aligning the interests of all the stakeholders: regulators’ social mission to connect populations,  protection of licensed incumbents, WS devices providers businesses and users’ expectations.

ITU took the opportunity of a panel dedicated to regulators’ visions to remind the members of joining ITU study groups to exchange best practices and propose recommendations.


Mr. Hervé Napoletano, ATDI Executive Vice President and Mr. Kalpak Gude, President, Dynamic Spectrum Alliance

What is DSA? The Dynamic Spectrum Alliance works to engage with regulators and government officials to promote the adoption of legal and regulatory frameworks that facilitate dynamic access to radio spectrum based on the policy principles adopted by the DSA. A key function of the Dynamic Spectrum Alliance is to generate responses to government and regulator consultations. Included below are links to consultation responses filed on behalf of the Dynamic Spectrum Alliance.

ATDI provides the most accurate Dynamic Spectrum Management System:

– Static and Dynamic concept
– Static spectrum maps by channel and technologies
– C/I maps calculated to protect receivers (and not based on extended transmitter coverage)
– Dynamic frequency assignment (<< 5 sec)
– Spatial and Time oriented Database
– Spectrum Sharing Areas, available channels and permit powers are accessible in real-time
– Multi-technologies, from 8kHz to 350 GHz
– Static networks are always protected and Dynamic networks are automatically optimized to minimize self-interference.
– Support: PMSE, TVWS, LTE, Wimax, Radars, DVB-T, ATSC, WiFi, Aeronautic…
– Allotments, Exclusion areas
– Cartography: Multi-resolutions from 0.1 m to 500 m, Projections “on the “fly”, Multi-layers (DTM, Clutter, Building heights)
– Pre-defined and user-defined filters (Rejection, C/I required, NFD matrix, TS/RIF)
– More than 100 propagation models: NTIA, ITU, Deygout94, COST, Okumura-Hata, HF, MF…
– WMS/WMTS geoportals
