Flexi Multiradio BTS GSM/EDGE Product Overview
•
Flexi Multiradio BTS is a base transceiver station that is part
of the Nokia Siemens Networks
Flexi BTS platform
for
GSM/EDGE, WCDMA, and
LTE
networks.
•
It is a multiradio or multicarrier BTS that can use all these
network technologies either in dedicated or concurrent
mode of operation
•
Its modular design
makes site acquisition and installation
easy, and reduces the time needed for rolling out network
coverage in a new area.
•
It allows using existing site space efficiently, the existing
Flexi BTS modules can be installed together with Flexi
Multiradio BTS modules.
•
The existing Flexi BTS cabinets and casings, power supplies,
and the 3G Flexi System Module can be used with Flexi

Flexi Multiradio BTS GSM/EDGE Architecture
Flexi Multiradio Architecture basic principles
•
Both GSM/EDGE
and WCDMA/LTE have own separate system
modules when the BTS is used in concurrent mode having several
operational modes simultaneously.
•
The radio modules (RFM
and RRH) as well as the antenna lines
could be shared between the system modules.
•
The
interconnections
between the
system modules
and
the radios
can be
routed through one system module
or the connections can
be
separate from both system modules
.
•
In concurrent operation
Flexi MR BTS is seen as two separate
logical network elements with common radio resources.
Flexi Multiradio BTS GSM/EDGE Architecture
Main functions of the modules
•
The System Module
is the center of the system. It has all the
external interfaces of the BTS (apart from the antenna interfaces).
Main functions of the System Module are the Transport, BTS O&M,
synchronization, power distribution and baseband processing
functions. System Module interfaces support up to four Radio
Modules with local power feed. Radio modules are connected to
System Module through RP3-01 interfaces.
•
The Radio modules and RRH’s
contain both RF BB and RF
functions. They are multistandard and multicarrier transceivers.
RF BB includes RP3-01 interface with multifunctional ASICs and
controller. In addition of TX/RX lineups module has integrated front
end. RFM front end will be implemented with SW tunable filters.
RRH will have fixed full band filters.
Smallest starting configuration with 2 modules:
•
System Module (ESMB/ESMC)
•
RF Module (RFM/RRH)
System Modules are GSM/EDGE compliant, and RF Module can be
shared with WCDMA/LTE in concurrent mode.

Flexi Multiradio BTS GSM/EDGE RF Module (FXxA)
General Information (3/7)
•
RFM is a single band module. Separate FXxA modules for each frequency band are
supported by Flexi Multiradio BTS
•
RFM operational bandwidth in both UL and DL is limited:
–
20 MHz for 1900MHz
–
30 MHz for 1800MHz in UL and 20 MHz in DL
–
20 MHz for 900MHz
–
12.5 MHz for 900MHz J-band (P-GSM for CDMA co-sitting)
–
15 MHz for 850MHz
•
There is a SW tunable pass band filter on each branch of the RFM module which is
tuned automatically by the BTS SW. The filter tuning range covers the whole RFM
bandwidth but the simultaneous bandwidth is limited as shown above

•
Each RFM branch (pipe) can support several carriers (frequency blocks for
WCDMA/LTE and virtual TRXs in case of GSM/EDGE) within the available RFM
bandwidth or the bandwidth can be shared between different technologies
•
Up to 6 carriers can be defined for GSM/EDGE (independently on RFM
bandwidth)
•
Carriers can be defined using 100 kHz frequency raster (minimum
400 kHz
of
the carrier separation needs to be kept between GSM/EDGE carriers)

In the
concurrent mode
there is a limited number of carrier configurations
supported by each RFM branch (pipe)
•
Dedicated SW features need to be used to enable RFM sharing between
different technologies (concurrent mode) - apart from the HW capabilities (max
no of carriers per pipe) the list of supported carrier combinations is determined
by the features

Flexi Multiradio BTS GSM/EDGE RF Module (FXxA)
General Information (6/7)
•
The nominal output power at the antenna connector for the 3-sector RFM is 60W
per branch (pipe)
•
The nominal output power at each branch (pipe) is the maximum cumulated sum
of output powers of all the carriers/TRXs within that branch
–
The output power per carrier of a radio branch decreases with the increasing number
of carriers in the radio branch
–
The output power of each carrier/TRX within the branch can be adjusted separately
•
The carriers can be split to multiple radio branches within one sector
to increase
the output power and thus the BTS coverage

•
In case of concurrent mode the nominal output power at each branch (pipe) is
shared between carriers of different technologies
–
There is a fixed share of the nominal output power of each branch (pipe) between
technologies
–
Then, the output power dedicated to each technology is distributed among defined
carriers (GSM) or limited according to installed license (LTE)
–
Dedicated SW features need to be used to enable RFM sharing between different
technologies
