Flexi Multiradio BTS GSM/EDGE Architecture


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.

Flexi Multiradio BTS GSM/EDGE Architecture Simpler architecture with fewer units 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 (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 No of carriers (TRXs) per sector

Output power per carrier in case RFM is working in a dedicated mode Flexi Mutiradio BTS GSM/EDGE – Sharing Session

Flexi Multiradio BTS GSM/EDGE RF Module (FXxA) General Information (7/7) • 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 ▪ RG10/RU20: RF sharing WCDMA – GSM ▪ RG25/RL20: RF sharing 2G – LTE – Maximum output power per carrier is determined by supported in the feature RF configurations

• The target receiver sensitivity of Flexi Multiradio BTS is to be at least the same as of the existing Flexi EDGE Receive sensitivity to be the same as with existing Flexi EDGE BTS

• Flexi Mutiradio BTS GSM/EDGE – Sharing Session


~2.0 ~2.0 RFM transmit power shared between several carriers has similar impact on the cell range as combiner losses in Flexi EDGE BTS Significantly less HW elements required in case of Flexi MR BTS  observed especially for higher BTS configurations Cell ranges of Multiradio BTS are comparable with Flexi EDGE BTS & BTSplus
