What are the prospects for 4.4 – 5 GHz as a mobile band?

The FCC is considering secondary mobile use of most of this band, adding to the groundswell of interest created by the plans to use 4.5 GHz for 5G in China and Japan. But wider adoption is likely to be hampered by NATO’s use of the band in Europe, as Toby Youell explains. Research… Read more...

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… Read more...

Does long-range IoT need better harmonised ISM frequencies?

In the last part of our series about IoT networks we consider whether they are being held back by patchy global harmonisation. The two key unlicensed bands used for IoT - 868 MHz and 915 MHz - are not globally adopted like 2.4 GHz, which spawned the growth of Wi-Fi.… Read more...

The role of satellite in extending terrestrial IOT networks

In the second of our series of Research Notes about IoT networks, we consider the benefits of adding a satellite component and the industry progress in achieving this. Dedicated terrestrial IOT networks such as Sigfox and LoRa - optimised for long range, low cost and long battery life -  are … Read more...

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

IoT is certainly a growth area for the communications industry over the next decade, but what does this mean in financial terms and which sectors are likely to benefit? Globally most mobile operators are suffering from flat or declining revenues, can a growing share of the IoT market turn things… Read more...

Countdown to WRC-19: satellite services

This Research Note focusses on satellite agenda items in WRC-19, principally the removal of a restriction on broadcasting-satellite services and improving spectrum access for movable earth stations and non-geostationary satellites. The USA, Canada and the Asian and European regional groupings support the removal of some of broadcasting-satellite service limitations but African… Read more...

Countdown to WRC-19: progress on the 5G mmWave bands

WRC-19 will consider identifying 11 possible bands between 24-86 GHz for 5G and opinions so far show that two are receiving the most backing: 26 GHz and 40 GHz. However, support for 26 GHz  is subject to ongoing studies regarding downlinks for earth observation data and the range of frequencies… Read more...

Countdown to WRC-19: more spectrum for HAPs and Wi-Fi?

Our second Countdown to WRC-19 Research Note looks at the mobile and fixed services, the topics covered in Chapters 1 and 2 of the conference preparatory document. Excluding 5G mmWave services, the first big issue is additional spectrum around 39 GHz and 20 GHz for High Altitude Platforms (HAPS), such… Read more...

Countdown to WRC-19: a new series of Research Notes

There are about 30 items on the agenda for the upcoming World Radio Conference (WRC-19) and we have been sorting through them to select those with the greatest industry-wide significance. We have produced a series of Research Notes focussing on six themes, explaining where there seems to be consensus and… Read more...

Assigning 700 MHz: a global overview

Steady progress is being made in releasing 700 MHz for mobile with 30 auctions anticipated over the next three years. Europe, Asia-Pacific and the Americas are the furthest advanced but few definite plans have been made in Africa or central Asian countries. Our latest Research Note explains the background with the help… Read more...
