RF Module operation and main blocks
1 RF Module operation and main blocks The 3-sector RF Module is a stand-alone fully operational transceiver module with integrated antenna filters. The RF Module is able to support one to three sectors in a Flexi Multiradio base station. The RF Module hosts the RF functionality and provides 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.
f Incorrect cables and seals may not provide secured weather protection. In outdoor installations, including the outdoor cabinet, use only tested, at least IP55 class outdoor antenna jumper cables provided by Nokia Siemens Networks. This is also recommended for indoor installations. The following versions of the RF Module are available Flexi Multiradio BTS LTE: Version

RF Module operation and main blocks
The 3-sector RF Module has three independent transceivers each composed of one transmitter chain and two independent uplink chains to implement uplink diversity. The unit integrates an antenna filter unit that contains three filter blocks, each composed of one duplex filter (main antenna) and RX filter (diversity antenna), providing six antenna connectors for the BTS antenna line. The transceivers can be configured independently to dual or single carrier modes. The RF Module uses nominal 48 V DC for internal power supply. In case AISG2.0 is used the following versions of RF Modules use 12 V DC only: • • • • •
FRIE Core version A101 FRGP Core version A101 FXEA version A101 FXFA version A101 FXDA version A101
The VSWR monitoring system is used for producing alarms for the antenna line condition against alarm threshold (RRH and 3-sector RF Module). As a default setting, the minor alarm will be generated when the VSWR is 1.9 and major alarm (cell down) will be generated when the VSWR is 2.6. However, it is possible to adjust both minor and major alarm threshold between 1.5-3.5. In terms of H-type configuration the main and diversity branches are reversed for the middle sector (sector 2).

RF Module and Remote Radio Head LED indications
7 RF Module and Remote Radio Head LED indications The RF Module and Remote Radio Head have two LEDs on the front panel to indicate the operational status of the module and all fault conditions during operation. Read the information on LED indications thoroughly. A blinking red LED does not always require removing the module. RF Module LED indications The RF Module LEDs are as follows: • •
one for the RF core functional block one for the fans in the RF Module
The LED indications of the RF Module are listed and explained in the tables below. Colour
Explanation
Red
Module self test or reset (LED red for < 5 second) or major alarm
Red, blinking
Minor alarm
Yellow
Module on and waiting or blocked
Yellow, blinking
SW download or configuration ongoing, module non-operational
Green
Module operational (cell can be locked in RNC)
Green, blinking
Module is loading software or parameters or local maintenance access when modules are operational
Table 21
RF Module core LED indications
In addition, the RF Module fan LED has an RF power ON/OFF display: LED mode
Explanation
Blinking
RF power off
Lit continuously
RF power on
Green
Fan is operational
Red
Fan is faulty
