All Nokia Flexi Multiradio BTS LTE modules are outdoor capable hermetically sealed and IP 55 class protected.

The number of modules is minimised, e.g. for typical a 1+1+1 configuration only 3 modules are needed.

Nokia Flexi Multiradio BTS LTE module mechanic parts

Module core

The Core mechanics with optional front and back covers shield the module against water, snow, and solid foreign objects and makes the module IP 55 weatherproof.

The Core mechanics provide EMC shielding.

All connectors are at front with weather protecting covers.

Module casing

Casing supports the pile of modules.

Module Core can be changed even the module is at the bottom of the module stack.

Fan sub-module

Fan sub-module provides the fresh air cooling to module.

The module controls the fan according to temperature information.

Two redundant fans enable module operation in normal temperature even with one fan.

The Fan sub-module can be changed in operational module at site where back access is provided.

Optional Front and Back covers for BTS site installations without cabinet or Optional Outdoor Cabinet

The outdoor cabinet includes door lock and door alarm switch.

Flexi LTE BTS Baseband (BB) processing

The Baseband Processor(s) (=Flexi Signal Processor version C, FSPC) terminates the Iub user plane and is responsible for L1 processing of the air interface.

The rel. 2 System Module type FSMC (not LTE capable) includes one signal processor, the FSMD has two and FSME has three.

System Module and RF module/RRH require 48v DC power supply.

In local installations, the System Module provides DC power supply to the Radio Modules.

In Feederless / Distributed Sites the DC power supply to Radio equipment may be provided by any other (48v) DC source.

For 24v DC environment there is a DC-DC converter 24v 48v available (FPDA).

RA41123EN08GLA0 30

Power is distributed from Flexi Power Distribution and Fuses (FPFA and FPFB)

to the System Module. The FPFA is used with System Module rel. 1, whereas in System Module rel. 2 it is replaced with the FPFB, which gives more power feeding capacity to RF Modules. The FPFB is compatible with both System

Module releases.

Functional description: FTLB supports following physical interfaces:

- 2 x electrical Gigabit Ethernet, RJ45 (10/100/1000Base-T)

- 1 x optical Gigabit Ethernet, via optional SFP (e.g. for 1000Base-SX/LX)

- 4 x E1/T1/JT1 symmetrical, RJ48 (coaxial E1 supported via baluns)

It provides HW supports for Ethernet features like:

- Dual Iub, Native Iub/IP

- Timing over Packet (ToP)

- Synchronous Ethernet (SE) slave functions

FTLB is prepared also for Synchronous Ethernet Regeneration. This

allows to synchronize either a collocated BTS or even a chained BTS on another site via Synchronous Ethernet.

All three GE interfaces can be used simultaneously with basic Ethernet

switching functionality (RAN1847 Basic Ethernet Switching).

The RF Module and Remote Radio Head (RRH) are stand-alone fully operational transceiver modules with integrated antenna filters. The RF Module and RRH are able to support one or two sectors in a Flexi LTE base station.

They host the RF functionality and provide control and power supply to the Flexi Antenna Line. Radio-related signal processing is performed in the RF Module.

The RF Module has integrated fans and Bias-Ts. The RRH does not have fans.

The RF Module can support one to three sectors with the following integrated components:

• Transceivers with TX for two carriers (three transceivers in the Triple RF Module, two in the Dual and one in the Single RF Module)

• Transceivers with RX for two carriers with diversity (the carriers must be adjacent) (three transceivers in the Triple RF Module, two in the Dual and one in the Single RF Module)

• Linear power amplifiers (three in the Triple RF Module, two in the Dual and one in the Single

RF Module)

• RF filters with main and div branch (three in the Triple RF Module, two in the Dual and one in the Single RF Module)

• 48 V DC input power supply

• Masthead amplifier and 3GPPAntenna tilt power feed and control for up to three sectors

• Interface to the System Module

• Interface for chaining System Modules (Triple RF Module only)

• Integrated fan assembly (two fans)

• Full operational bandwidth support

FPMA is the casing, AC and DC cable connector box and support frame for actual power sub-modules FPAA, FPBA and FPDA.

Flexi Power AC-DC Sub-Module (FPAA)

The main function of FPAA is to provide 48 V DC power from AC to be used by the BTS modules. FPMA can house from one to three AC/DC

rectifiers. Output power of each AC-DC rectifier is 1 kW.

Flexi Power Battery Sub-Module (FPBA)

FPBA is a separate optional sub-module to be used together with AC-

DC Module (FPAA). FPMA can house up to three Battery sub-modules.

Battery sub-module provides up to 10 minutes battery back-up time when the Flexi BTS site AC power mains is down. FPBA is maintenance

free Lithium Ion battery bringing significant savings in operaover 10 years of Li-Ion battery life time.
