Plum Presents: An overview on how to measure and monitor spectrum

For our second webinar “Plum Presents”, Richard Rudd, Director at Plum, has provided a brief, non-technical, overview on how to measure and monitor radio spectrum. A robust understanding of spectrum use, and changes over time is crucially important for spectrum regulators and for the developers of new services. Existing users also require an understanding of[…]

Richard Rudd will be chairing a session at the IET’s annual APC conference on Tuesday 16 November

Richard Rudd will be chairing the morning session of the Institute of Engineering and Technology (IET)’s annual ‘Antennas and Propagation conference’ (APC), hosted online. The morning session focuses on topics relating to ‘5G and beyond’. Speakers will discuss Digital Twins for wireless communication systems and the use of machine learning for Propagation. In the afternoon,[…]

The role of spectrum policy in tackling the climate change issue

The UK Spectrum Policy Forum (techUK), an industry-led organisation that advises the regulator and the government, has commissioned Plum to conduct a study on the potential impact of spectrum policy on combatting climate change. The report shows that spectrum policies can have a significant positive environmental impact and that policymakers must put green issues at[…]

UHF propagation in mountainous terrain

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[…]

Opportunity study for small cells in 26 GHz band in France

Plum carried out for ARCEP (France) an independent exploratory study about the opportunities and deployment options for small cells in the 26 GHz band in France. The study was of two parts: a qualitative study identifying the technical, economic, and social opportunities potentially offered by use cases in the 26 GHz band, and a quantitative[…]

The future use of UHF in ITU Region 1

Plum carried out an independent study, commissioned by the GSA, looking at the current and future use of UHF spectrum in ITU Region 1, focusing in particular on spectrum bands between 470 MHz and 862 MHz.  The report looked at all users of the spectrum, first considering the demand for mobile broadband and other telecommunications[…]

Cross border considerations

It is a well-known scientific fact, but one that is sometimes ignored, that radio waves do not respect borders between countries and geographic regions. This means that radio networks deployed in one country or region can cause interference to networks deployed across the border. The impact of the interference can vary considerably and in the[…]

Facebook V-band study

Google developed a computer interface system based on hand/motion sensing radar operating in the 60 GHz band. Facebook have concerns that the use of such devices might cause interference to wideband data transmission systems operating in the same band (e.g. Wi-Gig). Plum were commissioned to review the technical studies on the issue, and draft a[…]
