How will DSS affect 5G speeds versus 4G?

Question

Accepted Answer

Dynamic Spectrum Sharing (DSS) will not significantly increase 5G speeds compared to 4G.

Dynamic Spectrum Sharing (DSS) technology enables the simultaneous use of both Long-Term Evolution (LTE) and 5G within the same frequency band. This technology dynamically allocates resources based on real-time demand for either 5G or LTE services. However, a key characteristic of DSS is that it is not anticipated to deliver substantially faster speeds when compared to existing 4G networks.
Limited Speed Improvement Over 4G

While DSS facilitates the expansion of 5G coverage, its technical implementation means that users are unlikely to experience a dramatic increase in speed compared to 4G. The technology's primary benefit lies in its ability to allow mobile network operators to deploy 5G using their current spectrum holdings, often requiring only software upgrades. This approach rapidly widens the reach of 5G, but the speed gains over 4G are expected to be marginal rather than transformative.
Enabling Broader 5G Coverage

The main advantage of DSS is its capacity to rapidly expand 5G coverage across a wide area. By allowing 5G and 4G to coexist in the same spectrum, operators can leverage their existing infrastructure to roll out 5G services more efficiently. This strategy aligns with national goals to accelerate 5G deployment, allowing for a replication of current 4G coverage footprints with minimal additional investment in hardware.
Potential for Future Enhancements

Although DSS itself may not significantly boost speeds, it lays the groundwork for future advancements. The technology permits future carrier aggregation with new sub-6GHz spectrum, which could lead to improved performance down the line. This capability suggests that while the initial rollout via DSS might offer modest speed improvements, it provides a platform for more substantial enhancements as new spectrum becomes available and is integrated.
