Indoor Scenario


29/37


Indoor Scenario description

The differences between indoor and outdoor BTS are:

1. The equipments which under the tower are installed in the BTS room

2. RRU power Cables and fibers will go through switch room window to RRU

and antenna

3. Overhead cabling will be used

4. Rectifier is PS48300. BBU and RRU will power supplied by PS48300

5. BBU and DDF box will be installed in one separate 19 rack

6. Battery will be install in special battery rack and connect to PS48300


30/37


Indoor Scenario description

The similarities between indoor and outdoor BTS are:

1. All of the installation on the tower is same

2. The alarm plan is same

Dip switch for BBU and UELP is same requirement

Indoor Scenario

Swap Scenario


33/37


Swap Scenario

Swap scenario is basic same with installation new site:

1. Fellow layout, install all of the under tower equipments whatever indoor or

outdoor

2. Install RRU, RRU power cables and fibers

3. Install new antenna system

4. If the plan is use current sites old antenna

Open the connectors between antennas and jumper cables.

Use new jumper cables connect the RRU to antenna

The detail plan will be made with customer on site


34/37


Key point for Swap Scenario

1. Need pay more attention to the alive network. Do not shut

down, power off any running equipment without customers

permission.

2. Need confirm whether the old antenna will be used afterswap

3. Need confirm how about the old feed cables and antenna

after swap

4. Need confirm the swap time schedule


35/37





4. Conclusion


36/37


Conclusion

Good quality and customers satisfaction is built by us.

Please double confirm the fellows items before leave the site:

1. Check the site with hardware quality installation standard

2. GTMU, UELP, PMU dip switch3. APM30 inside cable connection

4. Alarm cables connection

5. Antenna azimuth, down tilt angle
