Digital Mobile Spectrum Limited (DMSL) and the four UK MNOs are required to propose a propagation model to Ofcom with which to assess the geographical coverage of the Shared Rural Network. Standard propagation models are unlikely to give reliable predictions in the mountainous terrain where the SFN is to be deployed. Plum were contracted to[…]
The 900 MHz and 1800 MHz spectrum auctions in Thailand have generated plenty of headlines over the last few months. These have ranged from the initial astonishment at the spectacular prices to the recriminations that followed after new entrant Jasmine failed to pay the licence fee and thus lost the licence it won. Plum was[…]
In order to identify where spectrum in the UHF bands could be made available for mobile broadband, Plum surveyed the television broadcasting markets across the Middle East and calculated how a move to digital television could free up significant amounts of spectrum in the sub-800MHz bands. Starting with the assumption that the number of channels[…]
Plum was commissioned by the Inter-American Development Bank to provide advice to the Mexican telecommunications regulator, the IFT, on the appropriate way of valuing spectrum ahead of a number of auctions. The IFT was set to significantly expand the amount of spectrum available to operators, and wanted to understand the appropriate level for reserve prices[…]
Plum and Aegis advised the IDA on technical, pricing and other assignment approaches for addressing congestion issues in the 400 MHz and 800 MHz bands used to deploy trunked radio systems (TRS) and private mobile radio (PMR) networks in Singapore. The study examined the likely development of standards and availability of equipment for PMR and[…]
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 led a 12 month study, working with Farncombe, to assess the options for future use of UHF spectrum in the EU – with a focus on the case for and against a converged mobile/DTT platform. The study involved: Wide consultation with, and three workshops for, industry players A detailed assessment of how audio-visual services[…]
Plum carried out a study into the social, cultural and economic benefits that would be expected if the government of Egypt released sufficient spectrum to mobile operators in order to overcome short-term and medium-term capacity constraints. The study built a model of the market with and without the spectrum, and looked at the impact on[…]
The GSMA wanted to gain an understanding of potential demand for DTT in sub-Saharan Africa within the band 470 – 694 MHz. In order to help the GSMA to achieve this aim, the study undertook a review of DTT requirements within an example set of countries and the implications for spectrum release based on RRC-06[…]
Plum was a member of an ITU team that advised the NBTC, Thailand on spectrum valuation methodology, derived spectrum values and advised on reserve prices for the 900 MHz and 1800 MHz bands. Reserve prices provide starting prices for different lots in an auction and so they are not an estimate of the value that[…]
