5G: where is the boundary between experimental and commercial?

PolicyTracker classifies 5G bands as first tier, second tier, third tier and experimental based on the likely deployment timescale, within five years being the quickest. Today we are concentrating on the experimental category.

The enormous practical difficulties of providing services even in the lower reaches of mmWave were highlighted this week when Deutsche Telekom said the current business case for 26 GHz “doesn’t work at all”.

The higher frequencies are even more commercially challenging. ZTE regards 70-80 GHz as the lowest priority and doesn’t even consider bands above this.

There is little opposition to the use of bands in the 80-90 GHz range for 5G but this is because the band is sparsely used compared to candidate bands in the lower ranges. A lack of opposition does not mean commercial enthusiasm and this becomes more obvious as we move up to 90-100 GHz and beyond 100 GHz. Leading players like BT and Telefonica regard these bands as  inherently unsuitable; Samsung is distinctly lukewarm and Ericsson sees 5G backhaul as the main use case.

On the other hand, research into bands above 90 GHz should be encouraged and here the US is a leader.  Funding the research is relatively cheap and it may lead to lucrative new services. But we must remember these are very long term initiatives – any commercial deployment is at least 10 years away.

Research Notes

80-90 GHz by Patrick Gahan
81-86 GHz is likely to be identified as a future 5G band – it is being studied by the ITU and has been proposed for release in the USA.

90-100 GHz by Patrick Gahan
A limited number of stakeholders support further research in this band with several proposals to ease regulation to stimulate innovation

100-200 GHz by Patrick Gahan
There is some interest in deploying 5G in these bands but work in this area is at an experimental stage.
