The purpose of the study was to develop a briefing note that covered the issues concerning the amount of radio spectrum required by terrestrial television services once they have migrated from analogue to digital transmission. The note explores the different digital TV technologies used around the world (PAL, ISDB, ATSC). It also considers the other technical issues,[…]
The work involved understanding the type of communications that would be needed in support of effective Smart Grids and then identifying potential spectrum, on a European basis, that could meet such requirements. Historically there was a limited number of power stations and the generated power was distributed, on demand, through the network to the end[…]
The feasibility of deploying adaptive fixed links in the 1800 MHz band to provide backhaul links in rural areas for the UK was examined for this study. Issues considered included regulatory constraints, cost savings, equipment development, bandwidth requirements, achievable link lengths, in-band interference, cross border coordination and harmonisation opportunities. An example scenario was considered where[…]
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[…]
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[…]
Plum carried out an impact assessment on the consequences of current spectrum assignment policy in India. It concluded that India was generating substantial economic losses through a policy of fragmented assignment of spectrum to competing operators.
Together with LCC this study examined technical aspects of a number of possible options for the licensing liberalisation in the 900 and 1800 MHz bands. The study examined the spectrum requirements and specifically the current usage of the GSM spectrum by the three operators (Meteor, O2 Ireland and Vodafone Ireland) and the potential to support the[…]
For ComReg conducted a study on the spectrum requirements for a nationwide TETRA network for the Emergency Services. The study aimed at estimating the amount of spectrum that might be required to roll out a national TETRA network in the 380–400 MHz band providing coverage to 98% of the landmass of Ireland for hand-portable terminals[…]
The study examined the demand for 3.5GHz spectrum for Wireless Broadband Access (WBA) services and the potential impact on the existing Fixed Satellite Services (FSS) users of the spectrum in Singapore. The work included analysis of interference between WBA and FSS together with potential requirements for additional filtering in the satellite receivers and also guard[…]
