Maintain a Healthy RF Communication Network

What becomes simpler• Base station is all modular designed with standard/or semi-standard interface.• BTS installation is close to “plug and play”, no complex demodulationmeasurement needed during installation/maintenance.• Software defined Radio (Baseband card) makes multi technology, multi-band support in a platform possible.• Almost all settings can be done remotely: total power, individualchannel power, channel, band, modulation scheme, coding scheme etc..

Changes and Challenges for RF Field Test

Copyright © 2011 Agilent Technologies5

What becomes more challenging• More networks operate at higher frequency, it requires a lot more basestation to cover the same area, in average, technician needs to cover more sites now.

• More active components exposed to outdoor environment: TMA, Remote Radio Head, Remote Electric Tilt, Smart antenna etc..

• More components in feeder: Diplexer, Duplexer, TMA etc..

• More antennae in a sector, isolation between antennae need to be measured and maintained carefully.

• Frequency assignment is a lot tighter. And higher frequency band is adjacent to commercial cellular band, it could create interference betweennetworks.

Cable and Antenna Tests

Measurements– Return loss – Cable loss (1-port)– Distance to fault – Insertion loss– Amplifier gain– Isolation

Challenges– Need fast sweep speed– Measurement reliability– Ease of field use


QuickCal: Provide Stable and Worry-Free Measurement in the Field (1 port and 2 port)

Issues in field testing:

- It is difficult to keep consistent calibration in the field- may not have readily available calibration kit- may not have readily available adapter kit

Agilent Patented CalReady and QuickCal:

-Each test port is calibrated when it is turned, ready to make measurement without any calibration procedures.

-Built-in calibration module with advanced port extensionalgorithm to move reference plane to end of adapter orcable without using an external cal standards


Long and High-Loss Cable Measurement


Cable Loss Measurement (1-port cable loss measurement)

- Accurate cable-loss measurement iscritical to decide if system has enough coverage or generate excessive interference. 1 dB additional loss is equivalent to 10% reduction of coverage area.

- It is not practical to measure an installed,long cable using 2 port measurement.

- When cable loss value is getting close tosystem return loss value, simple return loss / 2 is no longer applicable, algorithmneeds to be implemented to separate cable loss from return loss.


Filter Tuning in the Field

- Filter in the transmitter band is to make sure transmitter signal is withindefined channel specification, minimize spurious signal interfering adjacent channel.

- Filter in the receiver band is to make sure that not-wanted signal is keptout, improve receiver sensitivity.

- not all the filters shipped to the siteare properly tuned, frequency couldbe changed on the fly.


Verify TMA, LNA in Receiver Chain of BTS Over the Air

Verify TMA over 2 antennae

Verify LNAs in BTS over two antennae


Interference Analysis

Measurements• Interference signal detection• Signal monitoring• Signal identification

Challenges• Need fast sweep speed• Higher dynamic range and

superior sensitivity• Ease of field use


Case Study: Using Spectrogram to Find Intermittent Paging Signal Which Blocks UMTS 850 Uplink

Paging signal

UMTS uplink


Coverage Verification with Independent Source and Spectrum Analyzer

- Verify coverage before a new install.

- Antenna direction alignment.

- Indoor system testing, send a CW tune through the system, find out the coverage, penetration and system loss.


In Summary

Hardware maintenance• Cable and antenna system• Filter, TMA, diplexer, duplexer• Transmitter

Over the air signal management (interference management)• Internal interference• External interference• Inter-modulation interference

Carry Precision with You!


Challenges in today’s Microwave I&M business: Precision is not an option

- System testing under extreme temperature- Perform all microwave tests in shortest possible time

-Making measurements in dusty environment- No room for instruments with fans and vents!

- Maintaining equipment under wet and salty circumstances.- Many critical decisions are made based on measured data.
