Digital Dividend Spectrum

3G Americas have released a whitepaper titled, "3GPP Technology Approaches for Maximizing Fragmented Spectrum Allocations". There are quite a few interesting things that caught my attention. One of them is this section on Digital Dividend Spectrum about which I have mentioned before. Here is what the whitepaper says:

The Digital Dividend refers to the reallocation of significant amounts of spectrum as a result of the switchover from analog to digital TV, a phenomenon occurring across the globe. Historically, analog TV operates in the UHF band between 470-862 MHz.

The analog to digital switchover will free a substantial amount of spectrum for new services, including digital television and mobile broadband.

Mobile services will need at least 100 MHz of this spectrum for mobile broadband. The results of WRC 07 incorporate this vision, as well as the need to promote harmonization of these bands, as reflected in the following above.

As is planned, there is no one globally harmonized Digital Dividend spectrum band. Further, the APAC countries have the flexibility to adopt the Region 1 or Region 2 plans. The important task of promoting harmonization and aligning band plans as far as possible with WRC-07 agreement, in order to realize the benefits of harmonization for their citizens, now falls to policymakers to accomplish.

In fact, the EC recently launched a consultation on Digital Dividend spectrum. Noting that importance of taking prompt action “to prevent the emergence of fragmented national legacy situations” that would stymie the development of future equipment and services in the 800 MHz band, the consultation proposes that the EC undertake two urgent actions by autumn of 2009: (1) Member States that have not completed the digital switchover would be requested to confirm switch off of analogue TV under national law by 1 January 2012; and (2) the EC would draft a Commission decision, for regulatory opinion in the autumn of 2009 and formal adoption at the beginning of 2010, on technical harmonization measures for transitioning the 790-862 MHz band to non-broadcast uses.

Credit to 3G Americas for publishing these interesting white papers.
