What is the Dynamic spectrum sharing

Dynamic spectrum sharing allows operators to operate 5G and LTE in the same band at the same time. It is based on demand and the needs of the end user. 5G dynamic Spectrum sharing is a major advancement in the telecom industry.

The spectrum available to 5G varies from market to market. It depends on whether it is already in use in 4G. Another factor is the timing of auctions and licensing processes. Many operators do not have free spectrum available on those bands, which makes 5G dynamic Spectrum sharing important for efficient use.

The split of simultaneous 4G and 5G capacity is adjusted at the millisecond level. This ensures optimal performance for any mix of 4G  and 5G active devices in the network. This minimizes spectrum wastage. As a result, it gives the best end-user experience.

In the nutshell, DSS is a revolutionary new way of rolling out 5G which can be used in new mid bands (C-band). It can also be used in existing mid bands (800, 1800, 2600). This means reusing hardware, spectrum and sites. While doing so, it increases new mid- and high-band investment value, especially when 5G dynamic Spectrum sharing is deployed.

This means increased coverage with fewer new sites in less time. It leads to infrastructure savings. Ultimately, it gives the chance to be the first to have nationwide coverage in an extremely cost-efficient way. Clearly, 5G dynamic Spectrum sharing has become a key tool to accelerate deployment.

DSS has been deployed end of December 2019. Swisscom said it expects to have 90% of its population covered with 5G by year-end thanks to DSS technology but it is expected that “multiple large customers” will start using DSS around the first half of 2020.
