What is Microwave upgrade? MW upgrade = MW CAPACITY expansion by means of SW or HW

1. Capacity upgrade will result to KPI reduction with no change on hardware. 2. One MW channel can support up to 183Mbps maximum at freq 6, 7, 8, 15 & 23

GHz and one MW channel can support up to 252Mbps maximum at freq 11 GHz. 3. Dual-polarization can support double capacity. SW upgrade also need HW upgrade in case of required. But without consideration of

KPI, at least 183Mbps can be achieved only by SW upgrade. If higher than 183M expected, HW modification is needed, i.e, to replace antenna by dual-polarization.

Conclusion: the HW upgrade are caused by 2 reasons: 1. As SW upgrading, if maintaining the same or improving the KPI. HW upgrade is

needed. 2. SW upgrade can reach 183M, beyond this, you should replace the hardware, i.e,

the dual pol. Antennas to achieve.

Scenario 1: Upgrade capacity

Step

Daytime

1. Get link budget

2. Subcontractor reach Swap/upgrade area

3. Sub-con engineer can use Web-LCT

4. Laptop already install U2000 Web-LCT and working

Nighttime

1. MW engineer on Mini-NOC/BSC

2. Check existing link RSL & Alarm

3. Change ODU modulation mode for the far end of this link

4. Change ODU modulation mode for the near end of this link

5. Check RSL & Alarm , Should be working. If interference happen go to next step

6. Sub-con must be logging in NE fallback original data when communication failed due to frequency interference happen

Daytime 1. Identify the antenna to be upgraded, as per the azimuth.

2. Install antenna refer to existing antenna azimuth.

3. Install temporary RTN&ISU2&ODU to new antenna. Keep ODU mute. Set temporary ODU frequency same as existing one’s.

4. Antenna pointing to Far end existing antenna(Only pointing on this end)

5. Repeat the alignment steps on far end site antenna.

6. Turn off temporary ODU. Dismantle temporary RTN&ISU2&ODU and return.

7. Water proof for new antenna feeder hole.

Nighttime 1. Turn off existing link ODU;

2. Dismantle existing ODU, and move to new antenna.

3. Turn on ODU;

4. Check RSL to make sure new link normal;

Page 69

1. Use temporary RTN&ISU2&ODU for pointing. After pointing, return them to HW.2. Deliver same sub-band ODU as existing. Keep ODU Mute to do pointing in case interference.

Step

Daytime 1、 Install AOC

2、 IF cabling

3、 Use temporary IDU configure data. （ Each team should keep

one IDU for antenna alignment）

4、 Antenna Alignment/panning/fine tuning

Night time 1、 Power-off existing IF card then move IF cable to new ODU

2、 Configure parameters as per design

3、 Check alarms and do the trouble shooting if applicable

4、 Dismantle existing Antenna and ODU then return to warehouse

Step(Nighttime)

1. Identify the antenna to be upgraded, as per the azimuth;

2. Switch off ODU for one site， check RSSI DC voltage on the ODU to confirm the antenna is the right one to be performed;

3. Mark the Azimuth on ground. Dismantle the antenna.(Check existing antenna’s polarization and ensure new one’s polarization is the same);

4. Install new antenna & ODU. Pointing the antenna to far site as per marked azimuth;

5. Turn on ODU, and perform the antenna fine panning;

6. Cutover IDU cables, i.e, IF cable, clock cable, traffic cable, NMS cascade cable, and do the configuration as per engineering design;

7. Check service and alarm;

8. Do the same work for/on the other site.

Scenario 7： No Space For Install New Antenna on Tower(Frequency no change)

Upgrade step and materials – Hot Swap

Must mark the azimuth on ground before dismantle existing antenna

2. Switch off one site ODU， check ODU voltage to confirm the antenna is the correct one;3. Remark Azimuth. Dismantle the antenna.(Check the polarization and make sure new antenna polarization same);

site by site to Swap

For Change Frequency scenario, swap both

sites together.
