• LCCs – 45 Countries(Population: 2,553.8M)
WhiteSpace Alliance Objective
3© 2017 Dynamic Spectrum Alliance
• WSA is Technology and Standards focused organization that also works on policy and educational outreach.
• WSA leverages unused Television Band Channels to provide Broadband connectivity using Advanced Cognitive Radio technologies – Current focus is on cost-effective Middle Mile, Backhaul connectivity and Industrial IoT.
• It improves Spectrum Efficiency using advanced modulations, state of the art spectrum management and interference mitigation techniques
• It creates testing and certification programs for the WSA developed technologies and specification
• It works with regulators all over the world to create right policy frameworks

WhiteSpace Projects in India – Using Wi-FAR®, Wi-Fi®, LTE as well as SATCOM and Optical Fiber
Wi-FAR
LTE Small Cell
• A single technology itself is unlikely to be able to meet the UN SDG Challenge 9c
• Need Wi-Fi®, WiFAR®, LTE, SATCOM and Optical Fiber connectivity Convergence
• Need adequate license exempt spectrum in TV Bands as well as other bands to make this happen.

The calculation of radio propagation is based on the FCC regulation.
TV data in Japan is taken from a data book.
• WSAConnect® is based on the IETF Protocol to Access WhiteSpaces (PAWS) Standard
• Enables WhiteSpace devices to access the database to determined the available channels at that location
• Enables various WhiteSpaceDatabases to communicate with each other
