Multiband Ret for Jay Beam Antenna - Prepared by Ahmed Salah 1

Hardware connections

Connect Ret Cable

between RRU and MDCU

of Jay Beam Antenna

Hardware connections

Make Sure that Tilt indicator

plastic cover is well closed

this cover contains Metal plate

to terminate the servo motor

electrical circuit

without cover termination this

motor will not rotate.

Check license on RBS

Check the following features to be activated

1. Standardized Ret

2. Ret Cascading

Check license on RBS

Reconfigure RBS

› Export Cabinet & site equipment

› Return Cabinet equipment Auto (change nothing )

› Return site wizard and change :

- RET Type : ARTU_Cascading

- Antenna Type & Unique Hardware Id for Antennas

The sequence will be :

- 1st : 2100 MHZ ( Sector Antenna 1 )

- 2nd : 900MHZ ( External Antenna 1-2 )

- 3rd : 1800 MHH ( External Antenna 1-3 )

Unique Hardware ID

This Label Exist behind Each Sector Antenna (12 Digit for each band “Sequence”)

Reconfigure RBS

Create New Ret Profiles using EM

Two Ret Profiles

1. 900 MHZ Tilt Antenna Type = “53”

retType="1"

minTilt="0"

maxTilt="100"

retParam1 To retParam8=“0”

checkSum=" 37098 "

2. 1800 & 2100 MHZ Tilt Antenna Type = “52”

retType="1"

minTilt="0"

maxTilt="120"

retParam1 To retParam8=“0”

checkSum="22607"

Final View

Test procedure

Ask integration team to change Tilt from his side and make sure

that servo motor in Jay Beam Antenna rotate and Changing

Electrical Tilt

Make sure that no cross between fiber cables (No Cross sectors)

You can change and test electrical tilt using EM (Right click on

Ret Device and select Force calibration then select attributes ;

Finally change Electrical Antenna Tilt with different values 20 ,

40 , 60 and observe motor rotation)

Test procedure
