Expanding digital connectivity through satellite broadband in the 28 GHz band in Africa

Following our report on the use of 28 GHz (27.5-29.5 GHz) spectrum in the Asia Pacific region, this Plum paper considers the importance of the band for satellite use in Africa. With large parts of the continent not covered by existing telecommunications networks, next-generation high throughput satellite (HTS) systems are capable of delivering gigabit connectivity[…]

Expanding digital connectivity through satellite broadband in the 28 GHz band

This Plum paper considers the importance of the 28 GHz band (27.5-29.5 GHz) for satellite use in Asia Pacific. Next-generation high throughput satellite (HTS) systems are capable of delivering gigabit connectivity and the 28 GHz band is a key enabler to achieving this. For emerging Asian markets satellite deployments in the Ka-band can contribute to[…]

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.

Statistical analysis of ITU SRS database

The study involved a statistical analysis of the ITU Space Radiocommunications Stations (SRS) database (BR IFIC 2762, 4 February 2014) in order to benchmark differing satellite filing patterns between administrations.  The analysis method adopted enabled filing statistics to be presented principally by administration, time, frequency band and orbital slot.  The analysis was conducted for the[…]

Satellite filings and consultation support

Support was provided for satellite filings  (including link budget design) for Avanti Communications Ltd.  The company was awarded a licence to exploit the Digisat I and II filings at 33.5° W.  These filings granted Avanti the right to operate a broadcast service in the frequency allocation corresponding to the BSS plan (Region 1).  Avanti received[…]

Satellite location analysis

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 economic value of spectrum use in Europe

Plum provided the GSMA with independent estimates of the economic value of eight major applications of spectrum. These applications included mobile services, wireless LANs, terrestrial broadcasting, and satellite broadcasting. The consumer surplus generated by these applications was estimated across the EU 27 member states in 2013 and 2023.  In each case the methodology and assumptions[…]

Developing a national broadband strategy for Oman

This study, for the Government of Oman, proposed a strategy for rolling out affordable basic broadband to everybody in Oman within three years and high-speed broadband to virtually everyone within eight years. The benefits of such a strategy are considerable. There is now a substantial body of evidence which demonstrates that universal use of broadband-based[…]

Assessing the public value of satellite communications

Plum, Aegis and Britten Consulting advised the European Space Agency on the application of the public value framework to assess the value of satellite spectrum use. This involved consideration of a number of case studies on different classes of satellite services across various frequency bands, including fixed satellite services (FSS), mobile satellite services (MSS) and[…]
