What is a BS type 1 Nr base station?

BS type 1-C: NR base station operating at FR1 with requirements set consisting only of conducted requirements defined at individual antenna connectors. BS type 1-H: NR base station operating at FR1 with a requirement set consisting of conducted requirements defined at individual TAB connectors and OTA requirements defined at RIB.

What are base station active antenna system standards?

Our latest “Recommendation on Base Station Active Antenna System Standards” provides the industry with an updated set of parameter definitions, measurement methodologies and reporting processes. This enables a uniform way to describe the electrical and mechanical characteristics of the network side of the radio link (the “base station antenna”).

Is a base station passive?

Actually, in certain cases of downloading, the base station is passive in the sense that it only transmits the information it is ordered to. This is the case for instance, when the module downloaded on the handheld concerns only the application layer (refer to fig. 3), or when the installation of the downloaded module is planned for a later time.

Can cellular base stations be standardized?

It is hoped that the model can also be the basis for standardization of base station components. The paper will focus on cellular base stations for two reasons. One is the importance of base stations in making possible the system capabilities that users want to use and that network operators want to offer.
