I 3Remote Electrical Tilt I General Information

Time is money, and setting up a mobile site takes time. So why not cut set-up time by using

Kathrein’s optimised products? Kathrein’s RET products such as the FlexRET and RFID-RCU

guarantee quick and easy set-up through automatic antenna configuration. As an added benefit,

they minimise potential RET installation errors. Kathrein's RET control devices make initial configu-

ration and targeted optimisation much easier. What’s more, the Kathrein GPS Azimuth Adjustment

Tool allows fast and precise azimuth adjustment of the antennas on site.

Modern mobile communication networks often provide the pos-

sibility of controlling the electrical downtilt of antennas remotely. As a result, most antennas need to be equipped with Remote

Control Units (RCUs) in order to be able to change the downtilt

without the need to physically access the sites.

Not only do these RCUs need to be installed, they also need to

be configured in accordance with the connected antenna. This

results in an additional amount of time spent on site and a pos-

sible source of human error.

In order to make the whole installation process easier, Kathrein

is now offering two new solutions to simplify remote electrical

tilting of base station antennas: FlexRET antennas and a RCU

with integrated RFID feature.

The control unit is integrated into the antenna radome for

FlexRET antennas. One FlexRET module is able to control

up to six antenna systems of one antenna, i.e. up to 12 port

antennas. The integrated module is pre-configured and calibra-

ted ex-factory. That means all relevant antenna data is already

stored in the FlexRET module and is automatically transferred to

the used primary (e.g. Base Station (BTS) or ALC, PCA, ...). Asa result, this information does not need to be filled in manually

during installation.

The FlexRET unit provides one AISG input and one output.

Only one AISG cable is needed for control. Of course, FlexRETantennas can also be deployed in daisy chain configuration with

further FlexRET antennas and/or external RCUs.

For site/antenna sharing purposes, special Site Sharing Adap-

ters (type number 86010154/55) can be used. With these de-

vices, up to three respectively six different BTS or operators can

be interconnected to one common FlexRET antenna. Further

configuration details are given on pages 12-13.

All antennas with RFID tag will be clearly marked. One mar-

king can be found on the antenna label showing the following

symbol:

In addition, the packaging will also be marked with the same

logo.

Both systems are compliant to AISG 2.0/3GPP (default setting)

and AISG 1.1. An up-to-date list of all antennas with RFID spindle

is provided on our homepage.

All future Kathrein multi-band antennas will be equipped with

the new FlexRET system. Furthermore, Kathrein also provides

another innovative solution for all existing antennas with external

RCUs: A RCU with RFID feature, thereby providing RFID-based

communication between the antenna and the RCU.

This upgraded RCU is equipped with an RFID reader. In additi-

on, our portfolio of antennas is successively equipped with RFID

tags.

All relevant antenna data is stored on this tag, namely the anten-

na configuration file, the antenna serial number and the antenna

model number. After mounting the RCU to the antenna, all data

stored on the antenna tag is read by the RCU once the power

is switched on. Only specific site information needs to be addedmanually. The calibration is automatically performed when set-

ting the first tilt value.


ADVANTAGES FOR BOTH INNOVATIVE DEVICES

▪ No additional calibration and antenna type

configuration on site necessary

▪ Only site-specific information needs to be added

▪ Possible configuration and installation errors

can be avoided

▪ Saving installation time and costs

▪ Potential savings of Opex and Capex

8 I Remote Electrical Tilt I Control Devices

All complex functions and data which need more storage can

be transferred via WiFi to an arbitrary mobile device such as a

PDA, smartphone or laptop. An USB connection between the

Antenna Line Configurator and a laptop is also possible. The

mobile device does not need special software, a standard web-

browser is sufficient.

With one single Antenna Line Configurator, up to nine RET

devices, i. e. FlexRET antennas, external RCUs or a combination

of both can be controlled, depending on the system configurati-

on and the length of the control cable.

Antenna Line Configurator

The antenna line configurator is a stand-alone device for the

configuration and control of AISG antenna line products such as

Kathrein’s RET system. For operation, no external power supplyand no PC or laptop are required. The Antenna Line Configurator

is designed for on-site use and has a touchscreen display which

is sunlight visible. Its size is only 265 x 102 x 37 mm and it has

an extra clip to securely fix it during the site access.

A variety of functions can be controlled with the

Antenna Line Configurator:

▪ Scan for AISG devices

▪ Select and configure the scanned devices

(e.g. adjust the downtilt of the antenna)

▪ Documentation and protocolling of antenna installation

parameters in a report file

▪ Update the software of the used antenna line devices

such as RCUs, FlexRET antennas, DTMAs

▪ Check and store the mechanical downtilt of the antenna

with the internal tilt sensor

I 9Remote Electrical Tilt I Control Devices

Central Control Unit (CCU)

The Central Control Unit (CCU) is a base-station integrated de-

vice to control antenna line devices such as RCUs, FlexRET an-

tennas and DTMAs. In order to cover all required applications,the CCU can be accessed from the Operational Maintenance

Center (OMC) via the Ethernet input and/or directly on-site

through a PC via the RS 232 input.

For the control via a PC, the CCU can be operated with a stan-

dard browser which means no additional software is required.

Up to 27 RET devices (external RCUs or FlexRET antennas) and

six DTMAs can be controlled via one CCU, depending on cable

size and maximum power.

Portable Control Adapter (PCA)

The PCA is a portable controller for the on-site configuration of

ASIG antenna line devices, such as DTMAs, RCUs or FlexRET

antennas. This product is designed for mobile applications to beused by installers or maintenance staff with temporary access to

the antenna site. Mainly, the PCA is used for the configuration of

AISG devices directly after the installation.

The PCA consists of a small control box and Windows-based

software to be installed on a laptop. The control box with

dimensions of 40 x 95 x 160 mm (H x W x D) transforms the USB

interface into an AISG-conform interface (RS 485 & DC voltage).

Together with the supplied software, all functions of the connec-

ted devices can be controlled via a laptop.

Up to 27 RET devices (external RCUs or FlexRET antennas) can

be managed using one single PCA.

Adjustment of the Antenna’s AzimuthKathrein’s GPS Azimuth Adjustment Tool

Outdoor tablet

The outdoor tablet is included within the scope of supply and

provides a special app for the easy documentation of the site

installation. Within the app, not only the mentioned parameters

can be measured, but the whole site information can be docu-mented including photos of the site. A report can also be issued

and saved by this app. It is even possible to send the report

directly via e-mail with an additional SIMcard. Measurements are

also graphically and acoustically supported, thereby allowing a

hands-free operation of the tablet.

The basis for the functionality of a mobile communication net-

work is not only the quality of the used products but also the

site planning. If the site planning is not correctly and accurately

realised during the initial installation, then this may result in poor

network quality and a dissatisfied subscriber base. Therefore,an accurate site installation can be seen as one of the essential

issues in order to ensure the best possible subscriber or user ex-

perience. One critical parameter during the installation process

is the azimuth adjustment of the antennas on site. In order to

ensure the correct adjustment, a precise adjustment tool is nee-

ded. In addition, the sites are often hard to access, so the efforts

involved in the adjustment itself should be kept to a minimum.

Kathrein’s GPS Azimuth Adjustment Tool offers a very accurate

and easy-to-handle adjustment of the antenna’s azimuth. It con-

sists of a GPS-based measurement tool in combination with a

tablet for the adjustment control and site documentation.

The tool can be easily mounted to an arbitrary panel antenna by using different adap-

ter plates or a special mounting belt. It is extendable for best signal reception.

GPS AZIMUTH ADJUSTMENT TOOL FEATURES

▪ Measurable parameters:

· GPS position

· Azimuth· Mechanical downtilt

· Othometric height

▪ Up to six hours operating time

▪ Compact size and limited weight

▪ Wireless communication between tool and tablet PC,

no cabling necessary

▪ Suitable for all mobile panel antennas

A separate manual can be found on our homepage describing

the use and operation in more detail.

Installation GuidelinesFlexRET Antennas

Operation with Several BTSSingle BTS Operation

If the RET control of a FlexRET antenna cannot be handled via

one single RET-signal path, the different RET signals need to

be interconnected with a Site Sharing Adapter (86010154/55).

With these Site Sharing Adapters, up to three respectively sixdifferent BTS or operators can be connected to one common

FlexRET antenna.

The installation of AISG antenna line devices in between the

Site Sharing Adapter and the FlexRET antenna is not possible.

If needed, they must be installed prior to the Site Sharing Adap-

ter. The Site Sharing Adapter can be fixed at the mast with the

included tension band. Attach the AISG cables of the different

BTS to the AISG inputs of the Site Sharing Adapter. One control

cable then needs to be connected from the AISG output of the

Site Sharing Adapter (marked with “FlexRET”) to the AISG input

of the FlexRET antenna. If an input of the Site Sharing Adapter

remains unused, then please do not remove the protection cap.

Dependent upon the site installation, the use of the optional

grounding point of the Site Sharing Adapter may be necessary.

Before deploying the Site Sharing Adapter, one initial configurati-

on needs to be performed in order to allocate the corresponding

bands to the respective BTS.

A configuration file is created by specialised software which

needs to be uploaded to the Site Sharing Adapter by an ade-

quate primary. This can be realised directly with the Kathrein

PCA or by a firmware update routine with any AISG control de-vice (BTS or e.g. ALC). This process is described in more detail

in the Site Sharing Adapter manual.

For RET control of the FlexRET antenna via one base station

(BTS), only one AISG cable (RS 485) needs to be connected

to the AISG input of the FlexRET module of the antenna. To

achieve this, remove the protection cap on the AISG input whichis marked by the word “in”. The control cable needs to be fixed

with tightening torque of 0.5-1.0 Nm. This can be done by hand

or by a special torque screwdriver (type number 85010080).

After scanning the FlexRET device with the primary (i.e. BTS or

an adequate control device, such as the Kathrein ALC or PCA),

the following antenna information is automatically read out:

1. Antenna type number

2. Antenna serial number

3. Antenna configuration file

An initial calibration is not necessary since the FlexRET antennas

are pre-configured and calibrated to the minimum tilt.

RET modes

According to 3GPP, the FlexRET antennas can be operated in

SingleRET (default) and MultiRET mode which are switchable. The

mode required is dependent on the mode operated by the BTS.

Any queries related to the mode of operation of the base stati-

on should be directed to the corresponding BTS supplier. The setmode has no impact on the operation of the antenna but only on

the communication between the primary and the FlexRET antenna.

Remote Electrical Tilt I Installation Instructions




Daisy Chain Configuration Exchanging the FlexRET Module

FlexRET antennas can also be used in daisy chain configuration.

Remove the protection caps on the AISG input and output of

the first antenna which are marked by the words “in” and “out”.Connect the control cable to the input. Remove the protection

cap of the AISG input of the second FlexRET antenna and at-

tach a control cable to interconnect the input with the output of

the first antenna. Proceed like this for further antennas. Please

note: Do not remove the protection cap of the AISG output of

the last FlexRET module.

A combination with external RCUs in daisy chain is also possi-

ble. Please see the installation instructions for external RCUs for

more details.

The maximum number of antennas usable in daisy chain is

dependent upon the primary, e.g. up to a total number of nine

FlexRET antennas and/or external RCUs with the ALC.

All FlexRET antennas are delivered with an integrated RET mo-

dule. However, this module can be replaced if necessary. To

exchange the module, the two screws (type torx T-20) of theexisting module need to be released first.

The module will then slide out until an internal mechanical stop

occurs, the module will not fall out by itself. The module can

be released by pulling it further. The new module (type no.

86010153) can then be placed in the slot and the screws need

to be tightened with a torque of 3 Nm.

The antenna information is stored on an internal RFID tag in the

FlexRET antenna. The new FlexRET module gets the antenna in-

formation stored in the antenna automatically after the power is

switched on. It is not necessary to configurate the FlexRET withantenna data manually. Again, only specific information needs to

be added. Since the module is not yet set to the required tilt, an

initial calibration for each antenna system needs to be performed.
