Verizon Demos 5G with DSS in 850 MHz Band
Verizon, Qualcomm, and Ericsson today performed a live demo of 5G operating in a sub-6 GHz frequency band using DSS (dynamic spectrum sharing) technology, enabling the use of band 5 (850 MHz) for both 4G LTE and 5G NR technologies simultaneously. To date, Verizon has launched 5G only in higher-frequency mmWave bands that offer high speeds but limited coverage. 5G in band 5 would offer the same coverage as 4G in band 5. Verizon has mentioned plans to launch 5G in sub-6 GHz bands, but released few details and made few promises. Today's demo implies potential plans to deploy 5G in band 5. AT&T has already announced that it will also use band 5 for its sub-6 GHz 5G deployment. Today's demo took place at Qualcomm's Snapdragon Summit in Hawaii.

"T-Mobile now has the largest swath of unused low-band spectrum in the country," said T-Mobile CEO John Legere about the company's 600 MHz auction winnings. The company successfully won an average of 31 MHz (ranging between 20 MHz and 50 MHz) of the 70 MHz low-band spectrum auctioned off by TV stations and the FCC.
