As we are nearing the 2023 World Radio Conference (WRC-23) the positions of the Regional organisations and individual country administrations have been developed and confirmed for the different agenda items. However, what is less clear is what agenda items might be agreed for consideration at WRC-27. The question is what agenda items may be appropriate,[…]
There is growing interest in the use of remotely piloted aircraft systems (RPAS) for a wide range of private and commercial applications. These systems cover a wide variety of types referred to as drones, model aircraft, unmanned aerial vehicles (UAV) or unmanned aerial systems (UAS). As operational use increases rapidly, the provision of safe access[…]
Without access to radio spectrum it would be impossible to undertake national and international flights safely. Aeronautical radiocommunications systems are used to support communications, navigation and surveillance applications which range from two-way communications between air traffic control and pilots to on board weather and location radars. These applications make use of various frequency bands allocated[…]
With focus moving to early aspects of development for 6G, Plum was commissioned by the UK Spectrum Policy Forum (SPF) to research options for mid-band spectrum in 7-24 GHz in the UK. The study presents a review of current allocations for this spectrum range and how these may change in the period to 2030 and[…]
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[…]
Plum produced two research reports on satellite filing and associated regulatory processes to support a client on the development of its strategy for next-generation wireless communications. The first report examined the regulations and processes for securing access to spectrum and orbital positions for satellite services, including case studies on Starlink (SpaceX) and OneWeb. The second[…]
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[…]
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[…]
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[…]
World Radio Conference 2023 Agenda Item 1.3 calls for studies to examine the feasibility of allocating 3600 – 3800 MHz band to the mobile service (except aeronautical mobile) on a primary basis in Region 1 (i.e. Europe, Middle East and Africa). The band is already allocated to the mobile service in Region 1 but on[…]
