RUS Function

HI all,

What's the function of RUS "E******* Product", and what's the benefits of connecting two RUSs to one antenna.

thanks,

The RUS is E*******'s multi-standard radio unit (PA). It supports GSM, WCDMA & LTE. So for example if you get a band 8 unit it can support GSM900 and UMTS900. The usual reason you connect two to an antenna is if you want to have a MIMO configuration.

A multi-standard RBS supports installation of nodes of different radio access systems in the same cabinet. In a multi-standard RBS, the support system is shared between the nodes in the cabinet. Each radio access system node is managed separately using its own radio standard tools, but only the primary node controls and supervises the support system. Multi-standard configurations can be either single mode or mixed mode configurations.
§Single Mode
§Mixed Mode


Single mode allows an RBS to be configured with different radio access systems within the same cabinet.
Single mode allows the following combination of radio access systems:
§GSM and WCDMA
§GSM and LTE
§WCDMA and LTE
LTE and CDMA


Mixed mode allows nodes of different radio standards within a cabinet to share radio and antenna resources.
Mixed mode allows the following combination of radio access systems:
§GSM and WCDMA
§GSM and LTE
§WCDMA and LTE
§LTE and CDMA
