Richard Rudd was the lead author for a paper on the development of the new ITU-R model for building entry loss. This paper describes the derivation and form of the new model and highlights work that remains to be done in this area. The ITU-R has recently published a new recommendation giving a method for[…]
Richard Rudd was the lead author for a paper on measuring clutter loss and building entry loss. The paper found that models and measurements exist for building entry loss and for loss due to local clutter. However, there appears to be less information on the combined effects of the two mechanisms. The paper reports on[…]
Richard Rudd, along with Maziar Nekovee of the University of Sussex, authored a paper on the propagation of millimetre-wave frequencies in urban clutter. The paper describes path loss measurements carried out at 27 GHz in London and Brighton. The primary purpose of the measurement campaign was to provide empirical support for the development of clutter[…]
As operators start planning their 5G deployment, one important question that should not be overlooked is what should be done about existing 2G and 3G networks. The rationale for phasing out legacy networks is to ensure that spectrum is refarmed to the most efficient technology and by doing so reduce operating costs and optimise the[…]
Access to affordable and adequate broadband services is becoming increasingly important, as the digital component of national economies continues to grow. In this paper, we focus on the question as to how policy and strategy can be developed to enable efficient rollout of broadband services meeting the needs of rural areas, using the UK as[…]
mmWave is one of the new frequency ranges identified for use by 5G. This report by iDate and Plum considers the state of play and the prospects for the use of mmWave spectrum in the EU and identifies issues for demand, coexistence and authorisation of mmWave spectrum identified for 5G. While the report considers a[…]
The 3.5 GHz band is a core spectrum band for 5G deployment globally and many countries have either assigned this spectrum or are making preparations to do so. In the ASEAN (Association of Southeast Asian Nations) region, the 3.5 GHz band is used by different satellite and fixed services and its availability is less clear.[…]
This paper provides a case study on how the UK is attempting to incentivise full fibre rollout (whereby every premises has a direct fibre connection), and the challenges which these proposals pose. In the past, the UK was the first to introduce the ideas of anchor product pricing and wholesale pricing freedoms. These were subsequently[…]
We provided a diligence review for a private equity firm in support of a funding deal with a UK-based fixed wireless operator. Our work included management dialogue, review of dataroom materials, market assessment, technology architecture and dimensioning, and cost assessment. A report on risk assessment was presented to investors to advise on progressing the deal.
Plum conducted a research study for the Australian regulator ACMA to examine the international practices on the award of high-value spectrum, particularly for mobile use. The research covered a variety of award mechanisms adopted by regulators in other jurisdictions, including auctions, comparative tenders, administrative awards and hybrid formats. The outcomes of the awards were then[…]
