3 About the 5G New Radio Option
The implementation of the option 5G New Radio R&S SMW-K144 is based on the
3GPP Rel. 15 specification group TS 38.xxx. According to these specifications, the
3GPP defines a great flexibility of the signal on the air interface.
This section is a brief summary of the main air interface parameters, see Table 3-1.

Frequency bands as defined by the 3GPP Rel. 15 specification group TS 38.xxx.
You can however select also any other frequency within the frequency range your
R&S SMW supports (see Chapter 3.1, "Required Options", on page 12).
