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[…]
Plum supported EE in responding to Ofcom on proposed annual spectrum licence fees for 1800 MHz spectrum by providing advice, preparing a report which EE submitted to Ofcom and via a follow up presentation to Ofcom.
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[…]
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[…]
This study assessed the alternative use value – primarily for mobile services – of sub-1 GHz spectrum in the ITU Region 1 (Europe, Central Asia, the Middle East and Africa). The study focusses primarily on the 700 MHz band, which is currently allocated to broadcasting in ITU Region 1. It estimated the benefits of an[…]
Plum produced a report for the GSMA which considered the costs and benefits of synchronisation of spectrum release across Europe, particularly in relation to 700 MHz.
Plum advised Etisalat Nigeria on a range of policy issues in the context of the development of a national broadband plan.
Plum advised Vodafone India on spectrum value for the 1800MHz band in the context of a consultation by the TRAI on reserve prices for a forthcoming auction of the 900MHz and 1800MHz bands. Plum reviewed the approaches considered by the TRAI and then estimated values using econometric analysis and network cost modelling. The results of[…]
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[…]
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[…]
