Dynamic Spectrum Sharing: It’s Not Just for 4G and 5G

Ed Gubbins – Principal Analyst

Summary Bullets:

• Dynamic spectrum sharing (DSS) can improve the coverage and capacity of 4G/5G networks by allowing both technologies to efficiently share the same finite, licensed spectrum.

• Spectrum-sharing goes beyond 4G/5G, including 2G and 3G and potentially Internet of Things technologies, increasing its value and diversity.

As the 5G era dawns, a technology known as DSS has become a hot topic. DSS allows operators to use the same spectrum bands simultaneously for different radio access technologies. Specifically, the industry’s 3GPP standards enable using 4G and 5G in the same spectrum. It’s “dynamic” in that the network is continually re-evaluating user activity and reallocating spectrum to 4G and 5G traffic as needed – sometimes as often as every millisecond.
