5G in 26 GHz: what are the implications of interference to passive satellite services?

Over the past few months we have reported on the discussions about protecting earth observation services in 24 GHz against interference from 5G in 26 GHz. The latter is one of the most widely-supported 5G candidate bands under discussion at WRC-19 and has been identified as a 5G pioneer band in the EU.

In this Research Note, independent consultant Roberto Ercole takes a technical perspective on the techniques needed to protect the passive services, how these could affect the commercial prospects for 26 GHz and how this could affect operators’ decision-making as they choose between this band and 28 GHz.

5G in 26 GHz: a technical note on the implications of interference to passive satellite services

21 May 2018 at 11:47
The ability to use 26 GHz for 5G is limited by the need to protect satellite earth observation services in 24 GHz. But what are the engineering issues behind this? Independent consultant Roberto Ercole explains how they affect the commercial prospects for the band and could influence operators as they choose whether to deploy 26 GHz or 28 GHz.

Does long-range IoT need better harmonised ISM frequencies?

1 May 2018 at 12:20
Unlike the 2.4 GHz ISM band, the most attractive unlicensed spectrum for low-power IoT networks just below 1 GHz is not globally harmonised. Is better harmonisation needed and how much can be achieved?

The role of satellite in extending terrestrial IOT networks

In the second of our series of articles about IoT networks, we consider the benefits of adding a satellite component and the industry progress in achieving this.

Where’s the money for mobile operators in the IoT?

10 April 2018 at 11:29
Analysts expect mobile to dominate the market for IoT connections, but there is greater uncertainty about what this will mean for revenues. The key question seems to be, can operators provide more than just the pipe?

5G could enhance agricultural growth by delivering reliable and high bandwidth connections but there still are questions to answer over coverage and security.

Policymakers to stop adding difficult issues to standing WRC agenda items

16 May 2018 at 14:39
World Radiocommunication Conference (WRC) agenda items 7, 9.1 and 9.2 always concern recurring issues that regularly require amendments to the Radio Regulations. The increased use of these items is now attracting the attention of policymakers as they start to consider potential agenda items for WRC-23 and beyond as part of WRC-19 agenda item 10.

FCC wants mobile broadband to have more spectrum at 2.5 GHz

14 May 2018 at 13:17
The Federal Communications Commission (FCC) has published a Notice of Proposed Rulemaking that raises the prospect of an auction of 2.5 GHz spectrum in the mostly rural areas where it is not already assigned to the Educational Broadband Service.

Smart farming, using UHF spectrum, is helping to modernise agriculture

11 May 2018 at 12:01
Decades after the “green revolution” in agriculture, the use of UHF spectrum is driving big changes in farming. “It could be the biggest change to agriculture since genetically modified crops,” says Luis Pérez-Freire, chair of the working group on smart farming in the Alliance for the Internet of Things Innovation (AIOTI).

WRC-23 might legalise use of L-band for inter-satellite links

10 May 2018 at 14:13
The satellite industry is proposing to study changing the Radio Regulations to address the use of the L-band for data relays for non-geostationary satellites (NGSOs). Demand for these data relays might arise from universities operating CubeSats – a type of miniaturized satellite for space research – at low earth orbit.
