Why is interest growing in 4.5 GHz for 5G?

Where China and Japan lead, others tend to follow. So what is drawing the two telecoms superpowers to take such an interest in the 4.4-4.9 GHz band? Other sub-6 GHz bands, such as 3.4-3.6 GHz, might be more in the 5G limelight but our new 4.5 GHz Research Note explains… Read more...

When should merging mobile operators be required to divest spectrum?

Talk of a merger between US carriers T-Mobile and Sprint came to nothing but stimulated lots of discussion about how much spectrum they would have to give up. This made us wonder: do merging operators always have to give up spectrum? How do competition authorities decide how much divestiture is… Read more...

How much are the new 5G bands worth?

There has been much discussion of what 5G will be able to do; how countries can become leaders in the field; and which bands should be used for the technology. But there has been little discussion of the value of the frequencies above 3 GHz where 5G can demonstrate its… Read more...

Analysis of this year’s major spectrum auctions

Beginning with the United States' 600 MHz incentive auction this week, we will be analysing the results and consequences of this years significant spectrum auctions. In the coming weeks we will be examining Ireland's 3.5 GHz auction as well as taking a more general look at auctions in the 700 MHz band.… Read more...

Mobile in C-band: a long battle ahead

Only the 3.4 - 3.6 GHz and 3.6 - 3.7 GHz frequencies have been harmonised for mobile use at ITU level but there is growing support among  vendors and operators to see 4G and future 5G services in  3.4 - 4.2 GHz.   Regulators in Europe plan to allocate 3.4-3.8 GHz… Read more...

5.1 – 5.9 GHz: regulators are extending this band independently of the ITU

The 5.1 - 5.9 GHz Band is a key Wi-Fi band that is also used for unlicensed LTE technologies.  Although discussion on extending the band is on the agenda for  WRC-19,  several major regulators are already adding more spectrum to the 5.1 - 5.9 GHz Band. The major players in the… Read more...

26 GHz and 28 GHz: the gap seems to be narrowing

A row between members of a small community can be very divisive and many feared the failure to make 28 GHz an ITU 5G candidate band would lead to a serious schism. 26 GHz was included and it is these two bands which we focus on in our latest research… Read more...

5G: spectrum consensus builds but operator doubts remain

Our research notes this week discuss how views on 5G bands have coalesced since WRC-15, giving an overview of Tier One bands like 700 MHz and 3.5 GHz, 26 GHz and 28 GHz,  where large-scale deployment is expected over the next five years. Tier 2 bands, where deployment is expected in five to ten… Read more...

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… Read more...

What motivates OTT players’ approach to spectrum?

What motivates OTT players' approach to spectrum? Who is pushing the spectrum sharing agenda? Academics and some regulators for sure, but in industry terms it is the OTT players like Google, Microsoft and Facebook;  Operators are usually lukewarm about sharing. Why? We explain in more detail in this Research Note but in… Read more...
