Requirements for NSN Flexi BTS installation

• Operating temperature: -33°C to +50°C, temporarily +55°C– Same for all installations types (indoor and outdoor, with and without cabinet)

• It is recommended to install modules into shade, avoiding direct sunlight– In maximum usage temperature sun load of 1120W/m2 is taken in account

• In extreme conditions, e.g. high-salt mist (close to ocean) or polluted environment, outdoor cabinet with a filter is recommended

• Front and rear module covers are not used in cabinets that have a door, in all other cases they are mandatory

• For securing air-flow 40 mm open space behind modules is required – In cabinet and rack installations the open space can be behind cabinet if

sufficient air-flow to modules is secured (e.g. through gridded back wall)

Flexi EDGE Sector Module• Sector module is a logical unit consisting of 2 building blocks:

– Dual TRX (DTRX) module – Dual duplexer module

• Minimum one Sector module is needed per sector• There is space for 1-2 optional Wideband combiner (WBC) submodules in

DTRX module• Both units fit into a 3HU casing

3HU

Nokia Flexi EDGE Dual TRX Module (EXxA, 2HU)

• Dual TRX module (DTRX) is a 2 carrier TRX unit, used as: – a stand alone TRX module (2 TRX capacity)– or a Sector module with the Dual duplexer module (2 TRX capacity)– or as Double Power TRX, DPTRX (1 TRX capacity)– or for Intelligent Downlink Diversity, IDD (1 TRX capacity)

• DTRX consists of: – BASEBAND part that is common to both TRXs– RF part with 2 independent transmit (TX) chains and 4 receive (RX) chains– 0-2 Wideband combiner (WBC) sub-modules

• RX connections for diversity:– 2-way diversity: 2 RX inputs/DTRX used when both TRXs are in same sector

4 RX inputs/DTRX used when TRXs of the DTRX are in 2 different sectors

– 4-way diversity: 4 RX inputs/DTRX used (supported only with SRC or DPTRX)• DTRX connected to system module via single Gigabit Ethernet interface• Power feed from system module via single cable

Nokia Flexi EDGE Dual Duplexer Module (ERxA, 1HU)

• Dual duplexer (DDU) module together with Dual TRX create a logical Sector module– Min 1 DDU per sector is needed – DDU is attached to DTRX module

• DDU provides – duplex functionality to combine TX and RX signals to same antenna feeder – multicoupling– 2 antenna connections (for 1 or 2 sectors)

• 2 TX inputs and 4+4 RX outputs (4 RX from antenna 1 and 4 RX from antenna 2)• DDU contains

– 2 duplex filter– 2 Low Noise Amplifiers (LNAs) with high/low gain support for RX signal– 2 Bias-Ts with VSWR measurement functionality

• TRX loop is controlled through the DDU – Common TRX loop for all TRXs in same sector– Loop can be performed from either TX to any of 8 RX outputs (only 1 TX and 1 RX can be

simultaneously tested)
