The project provides an assessment of the broadcasting, electronic communication and spectrum regulation in the UK (including the UK Electronic Communications Code) and the risks that may arise from the current legislation/regulation and possible future changes. It considers all parts of business that fall under the legislation of these sectors.
Plum have recently collaborated with Huawei in undertaking a number of studies intended to clarify options for spectrum sharing in C-band. The report linked here addresses issues relating to the co-existence of LTE services and satellite downlinks in the same, or adjacent, spectrum. The report describes realistic field trials which illustrate the potential for geographical[…]
In 2014/15 Ofcom, the BBC and Arqiva undertook a joint review of the ‘UK Planning Model’, the algorithms and assumptions used for planning DTT services in the UHF band. Some of the technical work in this review, particularly concerning the location variability of UHF signals, was undertaken by Richard Rudd of Plum Consulting, who also[…]
On behalf of a UK telecommunications operator, we made measurements of the attenuation due to the woodland surrounding a satellite Earth station. The measurements, at 3.6 GHz, made use of a specially-developed channel sounder. Measurements were made in both summer and winter, and the results have been incorporated in ITU-R Recommendation P.833.
We undertook a number of modelling studies for Ofcom in 2014-2015, to inform their policy on technical conditions relating to the release of 700 MHz broadcast spectrum for mobile use. The most likely band-plan involved the user equipment (UE) handsets transmitting at frequencies immediately above the remaining broadcast allocation, with base stations assigned spectrum higher[…]
We have provided specialist technical advice to ‘Digital Mobile Spectrum Limited’, the UK body charged with managing issues of LTE to DTT interference at 800 MHz LTE. This work has involved a number of strands including; the development of algorithms and computer models for the site-specific prediction of interference from mobile base stations to domestic DTT receivers;[…]
Plum Consulting London LLP and Aegis Systems Limited announced today that they have entered into an agreement under which the business operations of Aegis Systems will become part of Plum. Plum is a leading provider of strategy, policy and regulatory advice on telecommunications, spectrum, online and media issues. Aegis Systems is a preeminent independent provider[…]
The aim of the study was to gain a better understanding of radio signal variability in different clutter types in order to aid the modelling of potential coexistence issues with DTT using the UK DTT planning model. Using our survey vehicle extensive measurements at different antenna heights and locations were carried out to gain detailed understanding[…]
There is an increasing expectation that wireless services should be ubiquitously available, with seamless connectivity whether the user is indoors or outdoors. It is therefore important that the impact of buildings on the propagation of radiowaves be understood and reliably characterised. Although many measurements have been made over the decades, it is not always easy[…]
The study estimated the risk of interference into breathing apparatus telemetry systems operating at 862.9625 MHz used by the Fire and Rescue Services (FRS) in the UK. The work undertaken fell into two parts; in the first part laboratory testing of breathing apparatus telemetry systems was undertaken to establish relevant interference limits while the second[…]
