1+1 Configuration with Separated Antenna Siae 1+1 Separated Antenna solution , use 2xODUs connected to the RF Hybrid Branching (RF Power Slitter) and Mount directly onto the RF Flexible Wave Guide which other side of Flexible Wave Guide mount onto the back of single polarization Antenna Dish.
Figure 15. RF Hybrid Branching Please note that the Flange Type of the RF Hybrid Branching will be different depending on Frequency Range. At the Figure 15. shown RF Hybrid branching for 6GHz. Wage Guide Installation When ODU and RF Hybrid Branching need to be installed with separate antenna .Extra care should be taken when installing the Flexible Wave Guide, this is because the RF integrity of the flexible wave guide can be easily compromised incorrectly. Below is an Flexible wave guide minimum E plane and H plane bending. Figure 15.1 Shown the example Flexible Wave Guide Bending Value.

Grounding ODU Every ODU installed into the Microwave Radio Network will need to be connected to a Lightening Grounding system .A minimum 25mm Grounding cable to be run to the closest Lightening Bar or Grounding structure. If there is no available lightening protection grounding bar the ODU can be grounded to the structure, either using a angle tower adaptor or bolted directly to the structure, all grounding connection will have electrical bonding plate applied and all paint/grease removed from the contact point.

With the variety of tower configurations Within the Mobile network, it is sometime Impossible to grounding the IF cable at the Top of the Tower/Monoploe, if this is the Situation then it is permitted to leave this Grounding connection off.

Grounding IF Cable All coaxial IF cables installed into the Microwave Radio Network will be required to be connected the grounding . Both PDH or SDH or IP Radio will follow this standard. There are 2 types of the IF cable that will be usually used for the PDH and SDH which is LDF4‐50 and LMR400 , for the standard grounding kit for this 2 cables is UEK 1 for LMR400 and UEK2 for LDF4‐50.

Grounding Surge Suppressor (Option) The Grounding of Surge Suppressor may be required to be installed at the Site that need strongly Lightening protection. The Lightening surge suppressor will be installed outside the equipment shelter or room as see below diagram.
Figure 30.Grounding Surge Suppressor installation Diagram DC Power Connection DC cable type Black or White 2 core electrical flex is is to be used between the RIM and DC power supply, normally the color code for DC is Black & Blue, (Black ) +ve connected to the buss bar ,(Blue) –ve terminated to MCB ( Main Circuit Breaker), Any color conductors can be used but they need to have the correct color heat shrink applied to the exposed ends to hide the incorrect color , example black heat shrink over brown color conductor. DC cable size 1.5 sqmm minimum for dc cable run’s less than 10m , for cable run over 10 m ,2.5 sqmm cable to be installed. Circuit Breakers Normally most of Mobile Operator require different standard of this MCB , but there is a main supplier in the market , which is Merlin Gerin “C” Curve MCB ,only to be installed into 19 Inch rack DC Distribution, second supplier is Moellor “C” Curve MCB only to be installed inside the Eltek DC Distribution , Other type can be used but not required much by the Mobile Operator.

1+0 Modular/Compact Link MCB rating 6A or 10A 1+1 Modular link MCB Link rating 2x6A or 10A 1+0 XPIC Modular /Compact link MCB rating 6A or 10A 1+1 XPIC Modular/Compact link MCB rating 2x6A or 10A When the Protected link is to be installed , the installer must ensure that the A leg DC MCB and B leg DC MCB are not located right beside each other, put as much as separation as possible between them, this is used as protection against accidentally leaning or dropping tools on to the DC Distribution panel and both DC feeds are switches off. DC Connection Equipment end of the Flex cable must be soldered into the DC connector pins , making sure not stray copper strands are present that could in the future short out to the case. MCB/Grounding end, each end of the exposed flex cable , black and blue need to be crimped into a ferrel of the correct size, these ends are then inserted into the MCB (Bule) –ve and Black +ve into the buss bar. RIM DC Power connector Input Voltage Range 40.8‐57.6 Vdc (Positive Ground) , Each RIM card Is protected internally by 3A 125V very fast blow Fuse, Note this not soldered and field replacement.

Link Commissioning The Link commissioning engineer must be familiar with Siae SCT/LCT or WebLCT software and how to set up the Siae ALCplus2 .The Link commissioning are required as the following 1. Pan and Tilt antenna for the Maximum Receive Signal Level 2. Ensure the Receive Level meets the specified level in the Link calculation sheet 3. If specified level is not achieved +/‐ 3dB variation from the value in a link calculation are acceptable Link Commissioning Pan & Tilt adjustment for integrated antenna solution please also refer to the manufacture installation instructions.
Link Commissioning RSSI Below is the a graph of received signal RSSI which is plotted against voltage, this voltage reading is taken from ODU’s BNC connector. An analogue 0‐3 volt Multi Meter is recommended for taking these instruments as it is response time quicker than a digital multi meter (DMM) and easier to get the peak receive level.

Figure 33. Detected Voltage Versus the RF Receive Level Field Engineer can also monitor the RX level by monitor at the screen of software WeBLCT Please note that Maximum Receive Level of ALCplus 2 must not strong over than ‐20 dBm to avoid the situation of RX saturate.

SNR must be at lest 33.6 dB to operating modulation at 256QAM
For operating the Link as Adaptive Modulation (ACM) the Modulation from 4QM to 256QAM of link will shift up or Shift down depending on the Receive SNR ( Signal to Noise Ratio) . Created By Monthien Satantoranin : Siae Microelettronica South East Asia Page 31 of 40
Link Configuration After commissioning the link and meets the Maximum Receive Level or meets the value that specified in Link calculation, then engineer must set up the Mian configuration of the link which are , 1. Frequency Channel 2. Modulation 3. Channel Bandwidth 4. TX Power 5. Capacity Frequency Channel Setting Connect to the IDU at LCT (USB port) by using the program WebLCT , then selected the menu Radio Brach 1A , if the configuration is 1+1 Hot Standby when adjust the frequency at the Mian Radio ( 1A) then the Standby Radio ( 2A) will follow automatically, but if the configuration is 1+1 Frequency Diversity , then the software WebLCT will be required to set up Frequency Channel of Radio 1 A and Radio 2A and must be Different Channel otherwise the software will warning and not allow user to apply the configuration.

Move UP and Down arrow to adjust CH. Frequency ( 250 KHz step)
Figure 35. Frequency Channel Setting on WebLCT Created By Monthien Satantoranin : Siae Microelettronica South East Asia Page 32 of 40
Please note that at the same link the Frequency of Both site (Local &Remote) must be set as the Same Channel And on this menu ,field Engineer must be set the sub‐menu as ‐
Carrier Only must be “Off”
‐
RT PSU must be “On”
‐
TX Transmitter must be “On”
Modulation Setting Siae ALCplus 2 can be set the modulation as Fix Modulation (ACM Disable) or Adaptive Modulation (ACM Enable). Please also remind that the link ( Local& Remote site) must be set as the same. For Fix Mode Modulation ,set ACM Engine as”Disable” and Set TX Power Constant Peak Mode as “Disable” also. Then select the modulation as your specified. For Adaptive Modulation , set ACM Engine as “Enable” and TX power Constant Peak mode can be set as “Disable” then the TX Power Mode will work as “Average” which all modulation scheme from 4QAM to 256QAM will be have the same TX Power, but if set TX Power Constant Peak mode as “Enable” then the TX Power Mode will work as “Peak “ then at each modulation scheme will work as different TX Power ,see below
ACM Engine set as Disable or Enable

IF user selected the TX power control mode as Automatic (ATPC) , user also have to set the Threshold of Local PRx High and Low range at least 3 dB different. User also can setting the Range of Minimum TX power to relative with the Power Mode “Peak” to make the ACM adjust the TX power suitable at each modulation level. This Example set the Max TX Power is 23 dBmand Min TX Power is 22 dBm Figure 44. Adjust the Min and Max of the TX power when setting the TX power control as ATPC
