New Flexi Multiradio BTS units

This section describes the new units in Flexi Multiradio BTS, The details of other, already existing units reused in Flexi Multiradio Solution (e.g. FSMx, Transmission Modules and other optional units) can be found in the respective Product Description documents for Flexi EDGE and Flexi WCDMA.

Flexi EDGE 18/36 TRX System Module

The new Flexi EDGE 18/36 TRX System module provides the GSM/EDGE specific functionality within the Multiradio BTS. It stores and runs the GSM/EDGE BTS SW and provides the GSM/EDGE specific external and internal BTS functions.

There are two variants of Flexi Multiradio System Module; with integrated baseband processing capacity: ESMB for up to 18 and ESMC for up to 36 GSM/EDGE TRX capacities. The ESMC provides maximum capacity, however in most applications the capacity of ESMB is sufficient. As the ESMB can be duplicated and chained, operator can start the site build-out either with ESMB or ESMC with both tracks providing expansion path to maximum system capacity (36TRX/BCF).

EDGE System Module has following main functions:

• GSM/EDGE BTS O&M,
• Abis and transport,
• OBSAI connectivity,
• power distribution to the radios,
• GSM/EDGE baseband
• BTS synchronization.

The BTS O& function in Flexi Multiradio System module unit takes care of Radio Software management, Configuration management, alarm handling and recovery, reference clock management and externals alarms and controls.

ESMB/ESMC has an integrated transport unit which provides the physical transmission interfaces and the transport functionality of the BTS. Six different network interface alternatives are offered: E1 symmetrical, E1 unsymmetrical, T1, Fast Ethernet, Gigabit Ethernet and Flexbus.

These transport interface variants are same as with Flexi EDGE System Module ESMA.

GSM/EDGE specific configurations

Following GSM/EDGE configurations are possible:

• Up to 12 cells.
• Up to 12 GSM/EDGE TRX/cell
• Up to 36 TRX BTS (BCF) level configurations for GSM/EDGE.
• Up to 108 TRX (36+36+36) site level configurations with Multi BCF/common BCCH.
• IDD (Intelligent Downlink Diversity) and 4-way UL Diversity
• Dual band configurations

All possible TRX/cell configurations can be built within these limits. In addition to symmetrical configurations like 2+2+2 between the cells also unsymmetrical combinations are supported like 1+2+3. A single radio branch can be shared between operators.

ESMx integrated transmission

The Flexi Multiradio BTS GSM/EDGE system module uses the same transport options as with existing Flexi EDGE BTS. The transport interface comes in five different types of plug in units inserted into the system module (ESMx):

• FIEA : 8*E1 asymmetrical
• FIPA : 8*E1/T1 symmetrical
• FIFA: 2*Flexbus; TNC-type 50 Ω coaxial connector
• FIQB: 1*SFP port, 2* Fast Ethernet, 4*E1/T1 symmetrical
• FIYB : 1*SFP port, 2* Fast Ethernet; 4*E1/T1 asymmetrical
