Multistandard Configurations
This section is not applicable to RBS-TMR.
A multistandard RBS supports installation of nodes of different radio access
systems in the same cabinet. The nodes must always be configured as primary
or secondary nodes.
In a multistandard 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.
Each node calculates its own cooling requirement; however, the primary node
determines the fan speed according to the highest cooling requirement.
Multistandard configurations can be either single mode or mixed mode
configurations. The following sections describe single mode and mixed mode
configurations in more detail.
5.1
Single Mode
Single mode allows an RBS to be configured with different radio access
systems within the same cabinet.
More information on single mode can be found in Expanding to Multi-Standard
Single Mode, RBS Configurations and Support System.
Single mode allows the following combination of radio access systems:
5.2
•
GSM and WCDMA
•
GSM and LTE
•
WCDMA and LTE
•
LTE and CDMA
Mixed Mode
Mixed mode allows nodes of different radio standards within a cabinet to share
radio and antenna resources.
Mixed mode requires a license. More information on mixed mode and supported
configurations and frequencies can be found in Mixed Mode in Multistandard
RBS, Expanding to Mixed Mode in Multistandard RBS and RBS Configurations.
