Competing visions of 5G and millimetre wave
It’s apparent to us from speaking with multiple customers that 5G very definitely means different things in each country. At the extreme end of the spectrum, we’ve spoken to some that classify 5G simply as anything related to mmWave technologies, even if it’s Wi-Gig. Elsewhere, the opposite is true, with big splits already emerging.

Quality of service

This gives several benefits, not least of which is increased bandwidth – 14 GHz in the unlicensed 60 GHz V band versus 0.85 GHz for the licensed 28 GHz (being used by Verizon) and 1.6/1.4 GHz for the 37 and 39 GHz licensed bands. And while operators prefer to work with spectrum that they can own and prevent others using it (see the fight between Verizon and AT&T to acquire Straight Path, or rather its high-band spectrum assets), owning specific (licensed) bandwidth is less essential in the mmWave bands.

Propagation in these bands is low and the spectrum can be reused easily, especially with beam-forming technologies which are easier to use in these bands. Additionally, air interfaces have become smarter and can now work together - hence you can turn your Wi-Fi on in a crowded space.

All this means that quality of service can be maintained by using shared networks based on these higher frequency bands, allowing cost of deployment to drop and operators to focus on not spots – and having spent rather too long on trains from our Bristol headquarters, this would address Lord Adonis’s criticism of the networks around the transport infrastructure and concentrate it here.
