20 + Importance of the Regulatory Function

21 + The Need for Spectrum Management Spectrum enables delivery of vital public & private services. New apps & growth of existing apps increase spectrum demand. Spectrum management: Facilitating efficient & effective spectrum enabled services while minimizing interference experienced A challenging multi objective optimization problem: How to predict value attained for a service spectrum allocation? How to ensure both tech. & non tech. efficiency? How to establish technical & operational parameters?

24 + Explorations are necessary & in progress How can we put whitespaces to use? License all bands Mix of licensed and unlicensed bands Consequences of using DSA equipment designed for other markets? Bands Interference GeoDB access protocol Are licensed bands underutilized? For what congested bands is service extension crucial? Can portions of reclaimed spectrum be used to address national/regional needs eg: Extension of (terrestrial) mobile services; Infrastructure-less emergency comms& public safety comms; Extension of marine coverage.

services on a household or individual basis, as far as reasonably practical.

32 + Universality The Universal Service Framework for Telecommunications Services in Trinidad and Tobago(2012) establishes that Universal Service is the provision of accessible and affordable basic telecommunications services on a household or individual basis, as far as reasonably practical. Basic services prescribed in the Universal Service Framework include Affordable broadband Internet services of throughput no less than 5 Mbps by 2015

34 + TVWS/DSA Examinations Examples of Policy Implications

35 + Basic Vehicular Dynamic Spectrum Access Scenario

36 + FCC Scenario Challenges Coverage User Data Rates Channel availability check time Channel move time

37 + Cell sizes for TVWS for V2X scenarios, adjacent channel operation

38 + What data rate is the user really getting?

39 + GeoDBLoading vs Protocol (US/UK)

40 + Average channel availability sensing time for vehicles with TVWS For specified ±50m geographic validity, a single vehicle travelling in excess of 6km/h would have passed through the valid region before the required sensing has been finished.

41 + Likelihood of channel switching For speeds exceeding 25km/h vehicles would again have exceeded the ±50m displacement. Further, there would be a need to perform a channel availability check for at least 30s before operating after a switch.
