Small Cell Bandwidth Per User Could Reach 12.75 GHz for Each User

Though mobile spectrum for purposes of coverage might not change nearly as much, small cell bandwidth could mean consumption as high as 12.75 GHz per user, in the small cell areas.

That could mean, by some estimates, a need for as 56 GHz of spectrum, to support multiple service suppliers, one study of the United Kingdom by Real Wireless suggests.

For 5G, 3.1 GHz per mobile operator might be required, according to Samsung researchers.

The typical tier-one mobile operator in European markets uses about 590 MHz of spectrum, each.
