The purpose of the work was to establish the location history of a number of satellites. A number of the satellites had claimed to have been in position to bring ITU filings into use on particular dates. An application was developed to download two-line element sets from SpaceTrack which provides “space situational awareness services and information with U.S.[…]
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[…]
This study assessed the alternative use value – primarily for mobile services – of sub-1 GHz spectrum in the ITU Region 1 (Europe, Central Asia, the Middle East and Africa). The study focusses primarily on the 700 MHz band, which is currently allocated to broadcasting in ITU Region 1. It estimated the benefits of an[…]
Plum produced a report for the GSMA which considered the costs and benefits of synchronisation of spectrum release across Europe, particularly in relation to 700 MHz.
Communications networks are undergoing a transition from copper to fibre, from 2G and 3G to LTE and from switched to IP. Where ex ante regulation applies transition involves particular challenges and trade-offs that differ from those applying to relatively stable pre-existing infrastructure. The rationale and approach to ex ante regulation should therefore be re-assessed to[…]
