The answer to all current and future network demands
Network planning is becoming ever more complicated,especially with 3G (UMTS) and 4G (LTE).The challenge for wireless network operators is to balance coverage, capacity, call quality and costs in order to gain maximum revenue from their network. Each of the above factors affects the others and so network engineers use many different techniques to establish the right balance they are trying to achieve.
One of these methods is adjusting the antenna’s downtilt. Here, the engineer must take into consideration certain facts, such as the weather, access to the cell site, availability of specialized installation teams and special equipment etc. Moreover, such an antenna adjustment can typically take several hours to perform.Since the cell site is usually switched off for safety reasons during such an adjustment, this results in lost calls and therefore revenue whilst these changes are being made. Consequently, operators tend to make fewer adjustments and so networks are often left operating unoptimized, which also eventually results in lost revenue for the operators.
However, with Kathrein’s Remote Electrical Tilt (RET) unit engineers can make the necessary adjustments without shutting down the whole system!
Further advantages of using Kathrein’s
RET system:
No need for specialized teams trained in altitude work or with special safety skills
Limited site access and/or time restrictions are not so important
No special platforms or other means of access to the antenna are required
Adjustments can be made and the relevant measurements performed speedily
Network alterations can be carried out irrespective of weather conditions
No reduction in coverage – cells remain fully operational whilst changes are being made
Operators estimate that approx. 20 % of UMTS equipment can be saved by using such a RET system

Devices for controlling the RET System
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 the opera-tion, no external power supply and no PC or laptop are required. The Antenna Line Configurator is made for on-site use and has a touch-screen 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, where the most important ones are:
Scan for AISG devices
Select and confi gure the scanned devices (e.g. adjust the down-tilt of the RCU)
Documentation and protocolling of antenna installation parameters in a report fi le
Update the software of the used antenna line devices such as RCUs, DTMAs etc.
Check the mechanical downtilt of the antenna with the internal tilt sensor
All complex functions and data which need more stor-age can be transferred via WiFi to an arbitrary mobile device such as a PDA, smartphone or laptop. A 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 RCUs can be controlled, depending on the system con-figuration and the length of the control cable.

Central Control Unit (CCU)
The Central Control Unit (CCU) is a base-station-integrated device to control antenna line devices such as RCUs 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 personal computer via the RS 232 input. For the control via a PC, the CCU can be operated with a standard browser which means no additional software is required.
For the control from the OMC, special Kathrein software can be used: the Antenna System Manager (ASM). This ASM is able to control the confi gurations of all antenna line devices on the antenna sites converging in the OMC.Up to 27 RCUs 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 confi guration of ASIG antenna line devices, such as DTMAs or RCUs. This product is designed for mobile applications to be used by installers or maintenance staff with temporary access to the antenna site. Mainly, the PCA is used for the confi guration 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 RCU can be controlled via a laptop.Up to nine RCUs can be managed using one single PCA.

Connection Possibilities for RET Control Devices
For the communication between the control devices and the RCU, three different options are possible:
Using separate RS 485 cables
Using two Smart Bias Tees (SBT) in the feeder lines
Via a DTMA at the antenna and a Smart Bias Tee at the base station
Depending on the respective application, either a CCU can be integrated into the base station or a PCA or Antenna Line Configurator can be used for the local configuration and control of the AISG antenna line devices.

Ways of controlling the RET System:
Communication between the OMC and CCU
The electrical tilt can be controlled either locally or remotely.
Local control:
The confi guration of the RET system and simple adaptation to network changes can be effected via local
RET – Software Tools
RET – Browser Application
The CCU runs a web-server. RCUs and CCUs, as part of a network, can be confi gured and controlled through a standard browser, e.g. Firefox, Internet Explorer – no additional software is required. The RET system can be controlled over a long distance directly on site.
The connection to each CCU is easily generated simply by typing in its own individual IP address. The website which appears contains all the required control functions for normal service and installation. In addition to permitting the confi guration and control of the connected RCUs and TMAs, the CCU program also displays the device status, command history list and various types of system errors. Via the alarm interface all AISG alarms can be read off.
It is also possible to perform CCU software updates. The browser application is a helpful tool for the installation team on site, especially during the initial confi guration of a RET system. Each CCU, and with it each of the connected RCUs, can be addressed and controlled individually.
Therefore, the browser application also offers a practical solution for responding to new situations by changing the individual downtilt angles quickly and easily.
control. In this case, an installation team must be sent to the site. A laptop is connected by means of a PPP link to the RS 232 interface on the CCU. Alternatively, the Ethernet interface may be used. Instead of a CCU, an Antenna Line Confi gurator or a PCA can also be used for local control.
Remote control:
Due to the required UMTS and LTE network optimizations, the downtilt of an antenna’s vertical radiation pattern has to be adjusted much more frequently than as compared with a GSM network. To meet this demand, a remote controlled system via the OMC is inevitable. The Ethernet interface can be selected for implementing remote control in a local area network (LAN) or a wide area network (WAN).
The following transport and application protocols are served by the CCU: TCP/IP, UDP, PPP, DHCP, HTML and ICMP/Ping, FTP, and SNMP.

Kathrein’s Remote Electrical Tilt Software Tools
RET – Antenna System Manager (ASM)
Via the Operational Maintenance Center (OMC), hun-dreds of sites are controlled at the same time. With the CCU browser application, not more than one CCU can be controlled at once. Hence, this tool is not suit-able for an extensive site control. Therefore, Kathrein has developed the Antenna System Manager (ASM), a special software tool which gathers the access to the functionality of all CCUs into one single application. The ASM is a SNMP based software installed on the OMC computer for detecting faults and realizing network changes and events in real-time. It offers an optimized solution for controlling up to 10,000 CCUs at once. The ASM is based on a Client Server Architecture whose database contains all important network parameters needed for the configuration and the current status of all connected antenna line devices. This tool provides an excellent possibility to manage a whole network via one single program integrated in the OMC .
