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.

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

Does long-range IoT need better harmonised ISM frequencies?
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.
