What next for DTT? The case for implementing T2 at the same time as 700MHz clearance

Plum assessed the social and economic impact of adoption of a more efficient transmission technology (i.e. DVB-T2) on digital terrestrial television (DTT) at the time of 700MHz clearance (assumed to be 2019-2021). If the 700 MHz band (694-790 MHz) is repurposed from broadcasting to mobile use, the spectrum available to broadcast TV would be reduced[…]

Sharing between IMT and DTT

This study considered the feasibility of co-channel co-existence between IMT and DTT systems operating in the 470 – 694/698 MHz band. The study focussed on the impact of interference from IMT into DTT systems. Due to relatively high antenna gains, EIRP values and fixed antenna masts positioned above the clutter, the protection of DTT receivers[…]

Benefits of digital broadcasting

Plum and Farncombe developed for the GSMA a summary of the benefits of digital broadcasting that flow to players on the broadcast value chain.  The benefits for the broadcasting industry of the transition to DTT include: An increase in the capacity of broadcast transmission networks by improving spectrum efficiency (i.e. more data can be transmitted per[…]

Setting reserve prices for mobile spectrum in Taiwan

This report, for the NCC, recommended reserve prices for the 700 MHz, 900 MHz, 1800 MHz, 2100 MHz and 2600 MHz band auctions in Taiwan. Plum used a combination of international benchmarking analysis, cost reduction modelling and full enterprise value modelling to provide indications of spectrum value. This provided a range of estimates of spectrum[…]

Terrestrial broadcasting use of spectrum – does AIP have a role in promoting efficiency?

This report considered Ofcom’s proposals for the potential application of AIP to spectrum utilised for national terrestrial TV broadcasting. In its consultation on spectrum pricing for broadcasting, Ofcom stated that, where there are constraints on spectrum release, it does not expect “…the application of AIP to meet its core objective of securing the optimal use[…]
