About This Document

About This Document Overview This document describes how to configure EasyRET2.0 antennas for SRAN8.0 base stations. It applies to Huawei BTS3900 V100R008C00 and later versions, providing guidance for field engineers to configure EasyRET2.0 antennas. The SRAN8.0 software version integrates software versions of single-mode GSM base transceiver stations (GBTSs), NodeBs, and eNodeBs. The following table describes the relationship between the SRAN version and base station versions. SRAN Version

Single-mode Base Station Version

SRAN8.0: BTS3900 V100R008C00

LTE: eNodeB V100R006C00 (eRAN6.0) UMTS: NodeB V200R015C00 (RAN15.0) GSM: GBTS V100R015C00 and V300R015C00 (GBSS15.0)

This document uses eNodeB V100R006C00 (eRAN6.0) as an example. For SRAN8.0 co-MPT base stations, commands for the GSM, UMTS, and LTE modes are the same. Therefore, this document also applies to GSM and UMTS base stations. NOTE 

Remote electrical tilt (RET) modules of the EasyRET2.0 antennas involved in this document can be used only for antenna information management modules (AIMMs) in LTE FDD base stations. (For details about AIMM specifications, see Table 1-1.) For details about how to configure the EasyRET2.0 antennas in LTE TDD base stations, see Smart Antenna LTE TDD Base Station Configuration Guide.



For base stations not sharing the main processing and transmission unit (MPT), commands for the UMTS and LTE modes are the same, which can be configured by referring to this document. Configuration processes for GBTSs remain unchanged. For detailed configurations, see section A.6 "MML Command List."



Antennas earlier than EasyRET2.0 include embedded unpluggable remote control unit (RCU) antennas (EasyRET1.0 antennas) and external RCU antennas. For detailed configurations, see the RET antenna base station configuration guide (including GSM/UMTS/LTE base stations).

Configuration Overview

2.1 EasyRET2.0 Antenna Configuration Preparation Processes for antenna configuration differ depending on whether antennas are installed for the first time.

2.1.1 Installing the Antenna for the First Time Step 1 Ensure that equipment hardware has been installed. Step 2 Fill the installation recording form. 

To install antennas in cascading mode, fill the installation recording form delivered with the antennas, as shown in Figure 2-1, and submit the form to the network administrator. Then, the network administrator can add RET antennas according to the form.



You do not need to fill the form if you do not install antennas in cascading mode.

2.1.2 Replacing the AIMM Step 1 Before AIMM replacement, record the original downtilt of the antenna and fill the installation recording form in the AIMM installation guide delivered with the AIMM, as shown in Figure 2-4. Step 2 Install a new AIMM. The relationship between antennas and AIMMs must comply with that described in Table 1-1.

Step 3 Fill other information in the installation recording form. 

To upgrade an MET2.0 antenna to an EasyRET2.0 antenna, or replace the AIMM of a single- or dual-band EasyRET2.0 antenna, fill the installation recording form shown in Figure 2-4, and configure the antenna based on the serial number (SN) specified in the form.



You can skip this step if you replace the AIMM of a tri- or multi-band EasyRET2.0 antenna.



You can check the end face appearance of an antenna to determine whether it is an EasyRET2.0 antenna or whether it needs to be replaced by an EasyRET2.0 antenna. On the RET module of the EasyRET1.0 antenna, the end face has round angles and two or no bolts. While on the RET module of the new EasyRET2.0 or MET2.0 antenna, the end face is square and has four removable bolts.

Other Application Scenarios of EasyRET2.0 Antennas

4.1 RET Antenna Configuration in Dual-eNodeB Scenarios In dual-eNodeB scenarios, perform the following steps using related commands to configure RET antennas on each eNodeB: Step 1 Turning on the Power Supply Switch to the RET Antenna Step 2 Querying the Operating Status of the RET Antenna Step 3 Scanning the RET Antennas Step 4 Adding an RET Antenna Step 5 Setting the Downtilt of the RET Antenna Step 6 Querying the Downtilt of the RET Antenna

CAUTION In dual-NodeB scenarios, the time-consuming commands, such as loading software, calibrating antenna, setting the downtilt, are not supported operating on both NodeBs at the same time. If these commands executed simultaneously on both NodeBs, the NodeB which sends command latter may fail or returns "busy". In this case, wait 2 minutes and then run the commands again. The following uses a quad-band antenna with four RCU SNs as an example to describe precautions during RET antenna scanning. Two eNodeBs are represented by eNodeB A and eNodeB B. 1

If the RET antenna with integrated RCUs is not configured, the SNs of all integrated RCUs can be scanned with Configure Status set to UNCONFIGURED on both eNodeBs. Figure 4-1 shows the SCN ALD command output on eNodeB A or eNodeB B. Four SNs can be scanned.

2.

If some SNs are used to configure the RET antenna with integrated RCUs by running the ADD ALD command on a eNodeB, only the unused SNs can be scanned on the other eNodeB. For example, if two SNs are used to configure the RET antenna with integrated RCUs by running the ADD ALD command on eNodeB A, only two remaining SNs can be scanned on eNodeB B. Figure 4-2 shows the scanning result on eNodeB A. Four SNs are scanned. The value of Configure Status is UNCONFIGURED for two SNs and CONFIGURED for the other two SNs.

Figure 4-2 Scanning result on eNodeB A

Figure 4-3 shows the scanning result on eNodeB B. only two SNs with Configure Status set to UNCONFIGURED are scanned. Figure 4-3 Scanning result on eNodeB B

3.

After all SNs are used to configure the RET antenna with integrated RCUs, only the SNs used on an eNodeB can be scanned on the eNodeB. For example, if two SNs are used to configure the RET antenna on eNodeB A and the other two on eNodeB B by running the ADD ALD command, then only the two SNs used on eNodeB A can be scanned on eNodeB A. Figure 4-4 shows the scanning result on eNodeB A. Only the two SNs used on eNodeB A are scanned with Configure Status set to CONFIGURED.

Figure 4-5 shows the scanning result on eNodeB B. Only the two SNs used on eNodeB B are scanned with Configure Status set to CONFIGURED. Figure 4-5 Scanning result on eNodeB B

4.

After the RMV ALD command is executed, the SNs of corresponding integrated RCUs are released, with the value of Configure Status changed to UNCONFIGURED. For details about how to delete an RET antenna, see section A.1.7 "Displaying the RET Device Data Dynamic Information." The SNs with Configure Status set to UNCONFIGURED can be scanned on both eNodeBs. For example, if two SNs are used to configure the RET antenna on eNodeB A and the other two on eNodeB B by running the ADD ALD command, then eNodeB A release an SN. Figure 4-6 shows the scanning result on eNodeB A. Two SNs are scanned. The value of Configure Status is CONFIGURED and for one SN is UNCONFIGURED for the other one.


Figure 4-7 shows the scanning result on eNodeB B. Three SNs are scanned. The value of Configure Status is CONFIGURED for two SNs and is UNCONFIGURED for another one. Figure 4-7 Scanning result on eNodeB B

4.2 Combined Antenna Configuration When combined antennas are used, perform the following steps on both ends of eNodeBs: Step 1 Turning on the Power Supply Switch to the RET Antenna Step 2 Querying the Operating Status of the RET Antenna Step 3 Scanning the RET Antennas

Issue 03 (2016-03-09)


22



SN scanning results of combined EasyRET2.0 antennas are different from those of common antennas. The SN of the combined EasyRET2.0 antenna contains color-coding digits to distinguish antenna ports and the sixth digit from the end to distinguish left and right antennas. For details, see Figure 2-7.

The following figure shows the eNodeB scanning results.

Step 4 Adding an RET Antenna Step 5 Setting the Downtilt of the RET Antenna Step 6 Querying the Downtilt of the RET Antenna

4.3 AIMM Replacement for EasyRET2.0 Antennas Replacement operations vary with AIMM models in EasyRET2.0 antennas. To replace AIMMs, follow the instructions provided in this section.

4.3.1 Upgrading a Single- or Dual-Band MET2.0 Antenna to an EasyRET2.0 Antenna Single- or Dual-band antennas do not have backplanes to store antenna-related information, such as configuration data, antenna models, bands, and RET SNs. Therefore, after a pluggable AIMM is installed, perform the following steps to input all RET information.

Procedure Step 1 Record the downtilt of the original antenna by pulling the ruler and reading the scale. Step 2 Record the relationship between the RET SN and antenna band. Step 3 Scan and add the new RET SN by referring to sections 3.1 "Turning on the Power Supply Switch to the RET Antenna" to 3.4 "Adding an RET Antenna." Step 4 After upgrade, load antenna configuration data and calibrate the antenna by referring to sections A.1.1 "Loading RET Antenna Configuration Data" and A.1.2 "Calibrating the RET Antenna." Step 5 Configure the antenna downtilt by referring to sections 3.5 "Setting the Downtilt of the RET Antenna" and 3.6 "Querying the Downtilt of the RET Antenna."



For detailed operations in Step 1 and Step 2, see the related AIMM installation guide.



The following figure (AIMM installation recording form) shows the relationship between the band and the AIMM SN after the single-band antenna is upgraded.



After the dual-band is upgraded, the relationship between the band and the RET SN is as follows: Place the top side of the antenna up and face the end where the RET module is located. Then, read the bands in an ascending order. If the bands are the same, read the bands from the left to the right or from top down. Match the bands with the last digit of the AIMM SNs. For example, as shown in the following figure (AIMM installation recording form), the SN whose last digit is 1 corresponds to a low band and the SN whose last digit is 2 corresponds to a high band.

4.3.2 Replacing the AIMM for a Single- or Dual-Band EasyRET2.0 Antenna Single-or dual-band antennas do not have backplanes to store antenna-related information, such as configuration data, antenna models, bands, and RET SNs. Therefore, after a pluggable AIMM is installed, perform the following steps to input all RET information.

Procedure Step 1 Record the downtilt of the original antenna by pulling the ruler and reading the scale or by running the command LST RETSUNBUNIT on the LMT Step 2 Record the relationship between the RET SN and antenna band. Step 3 Check and delete configuration information of the replaced antenna by referring to sections A.1.9 "Displaying the RET Dynamic Information" and A.1.10 "Deleting an RET Antenna." Step 4 Scan and add the new RET SN by referring to sections 3.1 "Turning on the Power Supply Switch to the RET Antenna" to 3.4 "Adding an RET Antenna." Step 5 After upgrade, load antenna configuration data and calibrate the antenna by referring to sections A.1.1 "Loading RET Antenna Configuration Data" and A.1.2 "Calibrating the RET Antenna." Step 6 Configure the antenna downtilt by referring to sections 3.5 "Setting the Downtilt of the RET Antenna" and 3.6 "Querying the Downtilt of the RET Antenna."

See the note in section 4.3.1 "Upgrading a Single- or Dual-Band MET2.0 Antenna to an EasyRET2.0 Antenna."

4.3.3 Upgrading a Multi-Band MET2.0 Antenna to an EasyRET 2.0 Antenna Tri- or multi-band MET2.0 antennas have backplanes to store antenna-related information, such as configuration data, antenna models, and bands. Therefore, no configuration data needs to be loaded. After a MET2.0 antenna is upgraded to an EasyRET2.0 antenna, perform the following step on the network management system (NMS) to configure the RET module and calibrate and set the downtilt: Step 1 Record the downtilt of the original antenna by reading the scale on the ruler. Step 2 Record the antenna band and RET SN on the antenna nameplate. Ensure that the antenna band matches the RET SN. Step 3 Perform configurations by referring to sections 3.1 "Turning on the Power Supply Switch to the RET Antenna" to 3.4 "Adding an RET Antenna" Step 4 After upgrade, load antenna configuration data and calibrate the antenna by referring to sections A.1.1 "Loading RET Antenna Configuration Data" and A.1.2 "Calibrating the RET Antenna." Step 5 Configure the antenna downtilt by referring to sections 3.5 "Setting the Downtilt of the RET Antenna" and 3.6 "Querying the Downtilt of the RET Antenna."

During AIMM installation, AIMM information is recorded on an installation recording form delivered with the AIMM installation guide, as shown in the following figure.

4.3.4 Replacing the AIMM for a Multi-Band EasyRET2.0 Antenna Tri- or multi-band EasyRET2.0 antennas have backplanes to store antenna-related information, such as configuration data, antenna models, and bands. When the RET module is to be changed, the RET SN and antenna information remain unchanged. Therefore, the RET module does not need to be configured and no configuration data needs to be loaded on the NMS. During AIMM installation, calibration and angle adjustment are required when the motor is faulty and the AIMM needs to be replaced.

The RET module can be directly replaced, which is convenient and reflects the advantage of the EasyRET2.0 antenna.

A.3 Color Coding Standard The following describes the method of representing the band features: According to the AISG Color Coding Standard, different colors are used to represent the color rings of the antenna port based on its band features. The upper band edge of the antenna port is represented in red, green, blue, and yellow in sequence from the low band to the high band, which describes the mapping between the colors and the upper band edges of the antenna port. In terms of a multi-band antenna, if the upper band edges of at least two antenna ports are in the same range, digits or repeateds letters can be used to represent the color coding. If digits are used, the digit 1 needs to be used to represent the color coding when only one color exists.
