Challenges of World Radio Conference studies: 10 GHz spectrum

The outcome of the World Radio Conference 2019 (WRC-19) has now been disseminated, changes to regulations and technical licence conditions are being implemented and spectrum awarded. Attention is now turning to the agenda items identified for the next World Radio Conference, scheduled for 2023 (WRC-23). Preparatory work will be starting within ITU-R, as well as[…]

Status of 5G field trials for connected and autonomous vehicles in Europe and North America

Plum produced a report for the Telecom Technology Center on the status of field trials involving connected and autonomous vehicles (CAVs) in Europe and North America. The report provided a selection of case studies involving the use of cellular technology (4G/5G) in developing: vehicle-to-everything technologies enabling interaction with infrastructure, other vehicles, networks and pedestrians; and[…]

It is all down to timing – spectrum transitioning

One of the more challenging aspects of spectrum management is ensuring the timely and orderly transition of frequencies where they are awarded to a new licensee. Where the frequencies are being used by incumbents to provide services, and there are no alternative providers or technologies available for end-users, it is particularly important to develop a[…]

Cross border considerations

It is a well-known scientific fact, but one that is sometimes ignored, that radio waves do not respect borders between countries and geographic regions. This means that radio networks deployed in one country or region can cause interference to networks deployed across the border. The impact of the interference can vary considerably and in the[…]

Facebook V-band study

Google developed a computer interface system based on hand/motion sensing radar operating in the 60 GHz band. Facebook have concerns that the use of such devices might cause interference to wideband data transmission systems operating in the same band (e.g. Wi-Gig). Plum were commissioned to review the technical studies on the issue, and draft a[…]

Coexistence of terrestrial and satellite services at 26 GHz

For the Australian Department of Communications and the Arts, Plum analysed technical conditions influencing spectrum sharing in the 26 GHz band between satellite services and mobile broadband including review of inputs into the WRC-19 process. Plum undertook a review of key sharing constraints proposed by the satellite operator and associated parameters, and assessed proposed technical[…]

Plum Insight – Balancing act: regulating space services

Understanding the regulations adopted by national regulators for the authorisation of space services can be a challenging task. Over the years, various authorisation schemes have evolved and been adopted in different countries. However, by its very nature, the space sector requires international cooperation, and the lack of standardisation has resulted in different requirements for the[…]
