- Dynamic Spectrum Sharing (DSS)

Dynamic Spectrum Sharing (DSS) is a new antenna technology that for the first time enables parallel use of LTE and 5G in the same frequency band. The technology determines the need for 5G and LTE in real time. The network then divides the available bandwidth independently and dynamically decides which mobile communication standard it best uses the available frequencies for.

For users, Dynamic Spectrum Sharing means: If you use a 5G smartphone to surf the Internet within the radius of an antenna equipped with the technology, you are surfing the Internet under the 5G standard. On the other hand, if you are surfing the Internet with a 4G phone within range of the same antenna, you are surfing the Internet on 4G. In short: one antenna, two networks. 


- 5G Operates on Two Frequencies

5G is not technically a separate network, but is joined by 4G cells to increase capacity. In addition to the 2.1 GHz frequency, 5G also operates on the 3.6 GHz frequency. However, this frequency is currently reserved for large cities. The reason for this lies in the characteristics of radio frequencies.

The 2.1 GHz frequency enables high-speed long-distance transmission. Therefore, it is well suited for 5G expansion in the region. The 3.6 GHz frequency enables very high data rates over a shorter range. So it is used in big cities. The interplay of Dynamic Spectrum Sharing and the extension of some sites on the 3.6 GHz band together forms the new 5G standard.
