Antenna System 2 Connection with TMA



2-1

2 Connection with TMA

This section describes the RF RX channel attenuation configuration, power supply configuration, andworking status monitoring configuration of the Tower Mounted Amplifier (TMA).

The connection with TMA function corresponds to the feature MRFD-210601 Connection with TMA(Tower Mounted Amplifier).

2.1 Overview of Connection with TMA

Installed on the tower top, a TMA is a device for amplifying uplink signals. As an optional component of the antenna system, the TMA compensates for the feeder loss caused by a long feeder to improve theuplink sensitivity and converge. NodeBs support TMA and smart TMA (STMA). An STMA has a built-inSmart Bias Tee (SBT) in comparison to a TMA. The power supply switch and attenuation factor need tobe set for both TMA and STMA.

In a network whose uplink coverage is limited, the TMA can be installed to improve the RX sensitivity

and expand the cell radius, reducing the number of NodeBs and minimizing investments. Users need todetermine whether to install the TMA according to the actual project requirements.

NodeBs power and control the TMA. Huawei NodeB provides the TMA with 10 - 13 V output voltage.When a major alarm related to the TMA is reported, the NodeB automatically sets the attenuation valueof the RX channel to 0. After the alarm is cleared, the NodeB automatically restores the attenuation valueof the RX channel to the configured value. The RET control signals, power supply, and RF signals of the TMA are transmitted through the feeder.This facilitates operation and maintenance. The SBT powers the TMA through the feeder and providesthe RCU with control signals.

Huawei NodeB also supports dual-TMA. Dual-TMA indicates that each TMA contains two pairs of RX/TXbranches. Each sector needs to be configured with only one TMA. Each TMA also contains a low noiseamplifier (LNA).

The functions of the two pairs of RX/TX branches of a TMA are the same. The RX channel has two RXfilters and one LNA. When the input DC is faulty, the LNA is automatically ignored. The Bias Tee isconfigured on the NodeB side of the TMA. The Bias Tee of a smart TMA (STMA) is referred to as an SBT.The Bias Tee can distinguish the combined signals of RF signals and DC signals, power the LNA, andprovide the RCU with RET control signals. The TX channel contains a TX filter, as shown in Figure 2-1.

GAIN Indicates the gain of the TMA subunit.

MODE Working mode of the TMA subunit.

2.2 RF Receiver Channel Attenuation

The TMA can improve both the uplink RX gain and the RX sensitivity. When the NodeB measures theuplink RX level, the measurement result must reflect the actual radio environment. Therefore, the TMAgain must be compensated reversely on the RF RX channel to ensure that the RX quality is improvedand the RX level reflects the actual radio environment when the NodeB measures the uplink RX level.

When the TMA is configured, users need to set the RF RX channel attenuation of the RF antennainterface and the RX channel corresponding to the TRX to obtain the TMA gain according to the actualrequirement.

For the NodeB, you can run the MML command ADD ALD to add the TMA for the antenna line device(ALD), run the MML command SET TMAMODE to set the work mode of the TMA, run the MMLcommand SET TMAGAIN to set the gain of the TMA, and run the MML command SET RXATTEN to setthe attenuation of the RX channel.

2.3 Power Supply for TMA

The TMA needs to be powered by the NodeB through the RF feeder:

For the NodeB, the RF module provides power for the TMA. You can run the MML command SET ALDPWRSW to enable the power switch.

2.4 Monitor TMA

The working status of the TMA can be determined according to the status of the feeding current on theTMA. The methods of reflecting the working status of the TMA through the feeding current varyaccording to TMAs. Users need to configure feeder boards for TMAs according to the actual TMAfeature configuration.

There are three alarm modes: MODE1 has only one type of alarm whose alarm severity is critical, andthe alarm current threshold is fixed and greater than the normal working current; MODE2 has two types

of alarms whose alarm severities are critical and warning, and the alarm current is fixed and greater thanthe normal working current; MODE 3 has two types of alarms whose alarm severities are critical andwarning, and the warning alarm current is periodical pulse current, while the critical alarm current isfixed.

Antenna System 3 Remote Electrical Tilt



3-1

3 Remote Electrical Tilt

This section describes a solution for remote adjustment of the antenna tilt.

The remote electrical tilt (RET) function corresponds to the feature MRFD-210602 Remote Electrical Tilt.

3.1 Overview of Remote Electrical Tilt

The RET refers to an antenna system whose tilt is controlled electrically. After an antenna is installed,the tilt of the antenna needs to be adjusted for the purpose of network optimization. With the RET feature,the phases of signals that reach the elements of the array antenna can be adjusted through electricalcontrol, so as to change the vertical pattern of the antenna.

The tilt of the RET antenna can be adjusted after the system is powered on and be monitored in real time.In this way, precise adjustment of the antenna tilt can be achieved.

The RET feature provides the following benefits:

The RET antennas at more than one site can be remotely adjusted at the same time. Therefore, theefficiency of adjusting the antenna tilt is improved and the cost of network optimization is reduced.

The adjustment of RET antennas can be performed irrespective of weather conditions.

It is easy to adjust the RET antennas at the sites that are difficult to reach.

The operating principles of RET are described in this chapter.

The related parameters of this feature are as follows:


TILT Tilt of the RET antenna.

AER Indicates the alarm error range for the tilt of the RET subunit.

3.2 Operating Principles of RET

The tilt of the RET antenna can be adjusted remotely.

The phase shifter of the antenna can be controlled by the stepper motor outside or inside the antenna.You can adjust the antenna tilt after the system is powered on and monitor the tilt in real time. Therefore,the precise remote adjustment of the antenna tilt can be achieved.

Figure 3-1 shows the operating principles of the RET antenna.

(DC+ control signals)

The Remote Control Unit (RCU) is the driving motor of the phase shifter of the RET antenna. The RCUreceives and executes the control commands from the MBTS to drive the stepper motor. A pulling bar connects the stepper motor and the phase shifter. When the stepper motor is triggered, the pulling bar moves and then the phase of the phase shifter changes through the gears. In this situation, the phase of each element of the array antenna changes regularly. Then, the direction of the main beam of theantenna changes accordingly. In this way, the antenna tilt is adjusted.

3.3 Operating Principles of Huawei RET

Huawei MBTS supports the following types of RET antenna connection:

Directly connect the RET through multi-core cables: It is applicable when the distance between theRRU and the RCU is shorter than 20 meters.

The MBTS supplies the DC power to the stepper motor and communicates with it through the AISGinterface on the RCU.

In the Huawei RET solution, the RET antenna can be controlled remotely or locally through a commandsent from the M2000 or LMT respectively.

When directly connect the RET through multi-core cables, the process of RET antenna control is asfollows:

1. The M2000 or LMT issues the control command to the BBU, and then the BBU sends the commandto the RRU.

2. The RRU modulates the control command into RS485 signals and then transmits the signals from theRS485 port to the RCU through the control cable.

When connect the RET via the SBT, the process of RET antenna control is as follows:

1. The M2000 or LMT issues the control command to the BBU, and then the BBU sends the commandto the RRU.

2. The RRU modulates the control command into On-Off-Keying (OOK) signals and then transmits the

signals and the DC power from the RF port to the SBT.

3. The SBT demodulates the OOK signals into RS485 signals and then transmits the signals and part of the DC power to the RCU.

When connect the RET together with STMA, the process of RET antenna control is as follows:

1. The M2000 or LMT issues the control command to the BBU, and then the BBU sends the command

to the RRU.2. The RRU modulates the control command into OOK signals and then transmits the signals and the

DC power from the RF port to the STMA.

3. The STMA demodulates the OOK signals into RS485 signals and then transmits the signals and partof the DC power to the RCU.

The Huawei RET solution supports the RET cascading control. Several cascaded RET antennas can becontrolled by the signals coming from the same control cable. The cascading solution helps save thecost of the SBTs.

The Huawei RET solution also supports the 2G/3G RET cascading control. 3G RET antennas can becascaded with 2G RET antennas. When they are cascaded, the tilts of the 2G RET antennas can becontrolled on the OMC for 3G, and the tilts of the 3G RET antennas can also be controlled on the OMCfor 2G. The cascading helps save the cost of SBTs when the 2G and 3G RET antennas are installed atthe same place.
