Radio spectrum is often organised (and sold) as paired spectrum – a block of spectrum in a lower frequency band and an associated block of spectrum in an upper frequency band . This arrangement of frequency bands with one band for the uplink and one band for the downlink is called paired spectrum.
Read moreWhat is paired and unpaired spectrum in 5G?
In unpaired spectrum, asymmetry may be provided through the use of unequal duty cycles in the time domain for uplink and downlink. In paired spectrum, asymmetry is also possible via the deployment of unequal bandwidths for uplink and downlink.22 Tem 2011

China has one of the largest 5G networks geographically speaking. South Korea was the first country to have 5G networks and devices that used them at the same time.
Read moreHow many bands are required for 5G?
Unlike earlier wireless generations, 5G requires a mix of spectrums across low (sub 1GHz), medium (3.5Ghz) and high (mmWave) bands .
Read moreWho has the most 5G spectrum?
T-Mobile has been named the top 5G provider by numerous independent research sources, including Ookla and umlaut. The carrier has a rich cache of mid-band spectrum thanks to its 2020 acquisition of Sprint Corp. in a deal valued at $26.50 billion.
Read moreWhich standards define 5G requirements?
The industry consortium setting standards for 5G is the 3rd Generation Partnership Project (3GPP) . It defines any system using 5G NR (5G New Radio) software as “5G”, a definition that came into general use by late 2018.

The FCC concluded its first 5G spectrum auctions in the 28 GHz band; the 24 GHz band; and the upper 37 GHz, 39 GHz, and 47 GHz bands . With these auctions, the FCC is releasing almost 5 gigahertz of 5G spectrum into the market—more than all other flexible use bands combined.
