On behalf of the GSMA, Plum estimated the potential impact of additional spectrum awards to mobile operators in India and Pakistan, focussing on the sub-700MHz spectrum bands which could be released after digital switchover. First, Plum analysed the current television markets in each country, to identify how much spectrum could be released once the analogue[…]
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 and Farncombe prepared a practical guide to digital switchover to supplement the information already published by the ITU and others. The guide focuses on a set of practical measures that anyone undertaking switch over / switch off must address, drawing on best practice from around the world.
The study was required to review the potential availability of UHF TV spectrum (digital dividend) for mobile / BWA services across Africa (in particular in South Africa) and to assess interference between Electronic Communications Networks (ECNs) and TV broadcasting systems in the UHF band. Guard-band / distance separation requirements were derived to bring interference between[…]
Plum supported the ECO impact assessment workshop with this case study impact assessment of receiver parameters for devices operating in the 863 – 870 MHz band. Plum also prepared a framework paper and ran a workshop on impact assessment for ECO members.
As part of the digital switchover process in the UK this study was undertaken to assess how closely actual antennas corresponded to those used by planners to assess coverage for digital TV. The primary technical objective was to analyse the new survey data that had been collected to determine whether there has been any significant change in[…]
The study examined options for the re-planning of the proposed Greek DTT network to allow the release of UHF spectrum above channel 60. It specifically considered the impact on the plan for the migration from analogue to digital of releasing the spectrum and the ability to support the planned TV stations and associated regional and national[…]
The Sekreteriat, charged with informing the Danish public about the Digital TV Switchover process (DSO), wished to understand the technical issues relating to off-air reception by the public. The study provided a report summarising general DTT issues, such as the impact of household aerial condition, the interpretation of coverage maps and man-made noise. In addition,[…]
The study was undertaken to investigate the scope for releasing digital dividend frequencies. High level analysis was undertaken of the impact of removing channels 61 – 69 on countries in the Middle East and Africa. The data on the proposed TV channel use was sourced from the ITU RRC 06 Planning Interface database, which contains details[…]
