Regulating for Quality of Service in Egypt

Quality of service is one the key metrics by which a mobile service is measured. Improving the quality of service that consumers experience is rightly important for Egyptian policymakers and regulators. Plum’s report, commissioned by the GSMA, explored how quality of service could be improved on Egyptian mobile networks to the benefit of consumers. International[…]

Measurement of vegetation loss at 3.6 GHz

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.

700 MHz modelling

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[…]

Measuring interference to DTT at 800 MHz

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;[…]

Incorporating social value into spectrum allocation decisions

As part of the UK Spectrum Strategy published by DCMS in March 2014, an expert panel was established to make recommendations on incorporating social value into spectrum allocation decisions. Tony Lavender of Plum was a member of the expert panel, which has now published its report.

To Buy or Not To Buy: the value of AWS spectrum in Paraguay

Plum carried out an exercise for Telecom Argentina looking at the value of spectrum in various bands for their operations in Paraguay. This project was designed to inform Telecom Argentina of the relative value of spectrum, and to influence their future strategy around participation in spectrum auctions and other spectrum acquisition.
