The Agilent Technologies E6474A Network Optimization Platform is a scalable, integrated,air interface measurement system. This system is used to support integration and maintenance of networks, obtain comprehensive callperformance and quantify the end-users experience for both voice and data.

Depending on the selected hardware options, the E6474A system can make UMTSreceiver and phone based measurements in the 1.9 GHz and 2.1 GHz bands of UMTS3GPP networks. Measurements from a number of engineering UMTS mobiles aresupported, including the Qualcomm TM6200, Motorola A835, Nokia 6650 and Nokia7600 models.

A laptop PC interfaces with the measurement phones and receivers for simultaneous dataand trace measurements. System software controls the devices to make and record user-selected UMTS measurements and protocol messaging. A GPS receiver, which can beintegrated within the Agilent measurement receiver, may be used to obtain positioninginformation that is stored with the measurement results. The system can also beconfigured for use with a pen-tablet computer for indoor measurements without a GPS.Logged data can be exported to mapping or post processing software for analysis.

Receiver measurements The receiver measurement functions of the Agilent E6474A Network OptimizationPlatform are provided by E6474A-310 and E6474A-320. These options, combined withthe E6455C or E6456C digital receiver option, are composed of four primary elements:

W-CDMA (UMTS) scrambling code analysis Spectrum analysis CW power with external trigger Channel power

Each element has an associated control and display view. The software can control up tofour Agilent digital receivers for simultaneous monitoring of up to four 5 Mhz bands. Thecontrols listed below are available for the receiver measurements:

Measurement interval- Time- Distance

Averaging (spectrum, CW, and channel power only)- Running- Group- Max hold- At least (CW and channel power only)

The measurement interval defines the duration between measurements. This can bespecified in terms of time (execute a measurement every 200 milliseconds), or distance(execute a measurement every 10 meters). There are two ways to define the interval bydistance. One is with the use of the GPS and the other is by using the external triggercapability.

22

Receiver measurements applicable to each of the four views are detailed in the followingsub-sections.

W-CDMA (UMTS) The Agilent E6474A receiver-based system measures 3GPP W-CDMA (UMTS) physical scrambling code analysis layer. The system makes absolute and relative power measurements of the primary sync

channel, secondary sync channel and the scrambling codes (CPICH). These measurementsare independent of network parameter settings. The system executes three different typesof W-CDMA (UMTS) scrambling code measurements (listed below). Any or all of themcan be executed simultaneously and in conjunction with other types of measurements,such as spectral analysis.

Measurement types Primary SCH scan:The system measures the power in either Ec and Ec/Io and Eb/Io of each Primary SCH.The results are displayed as a trace that shows the power for each primarysynchronization channel detected in one timeslot of 2560 chips. Exported data has Ec,Ec/Io, and Eb/Io available.

Top NThe system measures all of the scrambling codes in a timeslot of 2560 chips and returnsthe N strongest scrambling codes received, where N is a user definable integer from 1 to 20. The sensitivity can be varied by averaging over several time slots. The results aredisplayed in a bar graph format. (The primary sync and secondary sync are also measuredas part of the Top N measurement and can be displayed on top of each bar in the bargraph).

User listThe user manually inputs a list of up to 40 scrambling codes to be measured. It should be noted that this measurement only correlates the codes chosen by the user and does not process any sync channel information.

Measurement controls Carrier frequency

- Frequency- Channel

Measurement types- All sync channels- Top N- User list

Sync channel decode

The properties dialog box for the UMTS scrambling code analyzer gives an additionalcontrol that allows the user to set the rate at which a full synchronization of the SCHtakes place. A setting of 1 to 50 allows a trade off to be made between speed andintegrity. A setting of 1 (default) carries out a full sync (primary and secondary pilot syncand Scrambling Code (SC) processing) every measurement update. A maximum setting of50 carries out a full synch every 50 measurements with the remaining 49 measurementsprocessing for SC on the detected pilots.

Measurement methodologies In Top N measurements scrambling code, peak power (Ec,Ec/Io and Eb/Io) is and definitions computed as follows:

The receiver averages over a user defined number of timeslots and selects the strongestsignal of the visible range. The value of the associated secondary sync is then correlatedfor power and the secondary sync sequence is achieved to determine the scramblingcode group. The scrambling code (or codes) variables are then determined from withinthis group. This is repeated for all values of primary syncs above the pre-determinedthreshold and in accordance with the user selected Full SCH update rate control.

Io is the total received power integrated across the entire 3.84 MHz signal bandwidth.

Scrambling code aggregate power (Ec,Ec/Io,Eb,and Eb/Io) is computed for agiven scrambling code by integrating the power received over the time dispersion of thatscrambling code.

User List Ec,Ec/Io,Eb/Io is calculated by correlating the energy attributed to the userdefined scrambling code. This is calculated directly and does not use the sync channel.

Delay spread is the duration of time over which this power is dispersed. Both aggregatepower and delay spread are determined with respect to an Ec/Io threshold of -17 dB. Thesystem also reports the difference between the aggregate and peak power (aggregate peak). This difference along with the delay spread provides a characterization of themultipath effect on that scrambling code. Aggregate power and delay spread are onlymeasured for the Top N and user list measurement types.

Relative time is defined as the difference in time between when a scrambling codesignal is received relative to the start of the 2560 chip timeslot as arbitrarily defined in thereceiver. For example, the receiver will arbitrarily record a 2560 chip sequence where thebeginning of this sequence is defined as zero time. Each scrambling code will have somedelay from this start and thus will have a relative time to the start of the time defined inthe receiver.

Carrier frequency error is defined as the difference between the measured carrierfrequency and the user-specified carrier frequency. Carrier frequency error can be due toboth base station carrier error and doppler shift (if moving).

Scrambling code measurements Typical performance measures:

General parameter thresholds for the Top N measurement with no other viewsopen.

1. Primary sync with Ec/Io greater than the noise threshold which equals -21.0 dB forgreater than 12 timeslots, will be processed. The rate at which measurements describedin 1 and 2 are applied is determined by the user selected Full SCH update rate control.

2. Each and every associated secondary sync, with Ec/Io greater than the noise whichequals -21.0 dB for greater than 12 timeslots, will be processed. There can be multiplesecondary syncs per each primary sync.

3. For every secondary sync that is processed, any and all scrambling codes within thatgroup, of amplitude greater than -20.0 dB, will be reported.

4. If no scrambling code can be detected under a processed secondary sync, then the groupalone will be reported, if the secondary syncs Ec/Io value is greater than -17 dB.

CW power and channel power The Agilent E6474A can measure the peak power (CW power) at user-definedfrequencies within a user-defined resolution bandwidth. The systems can also measurethe total power (channel power) within a user-defined bandwidth at a user-defined set offrequencies. Channel power differs from the CW power measurement in that the totalpower is integrated across the specified channel width. The user can define thefrequencies measured in two different ways, indicated below.

Frequency entry methods List: Enter an arbitrary list of frequencies. Trace: Enter a start frequency, step size, and count.

The system measures at the start frequency, at the(start + step) frequency, (start + (count -1)*step)frequency. For example, if the start frequency is set to1900 MHz, the step size is set to 1 MHz, and the countis set to 4; then measurements are made at 1900 MHz,1901 MHz, 1902 MHz and 1903MHz.

Frequencies can be specified in terms of frequency units or channel number.

External pulse triggering is used for precise distance measurements by using pulses sentfrom the vehicle speed sensor to detect how far the vehicle has travelled. A maximumpulse rate of 3,333 pulses/second with a minimum pulse width of 100 ns can bemeasured. (At 1 pulse per centimeter, this would correspond to a speed of approximately120 km/hour). The maximum TTL voltage is 15 volts and triggering is on the negativeedge of the pulse.

Note: Specifications describe warranted performance over the temperature range of 0 to 55 Celsius and include a 30 minutewarm-up from ambient conditions. Typical and characteristic information provides useful but non-warranted performanceparameters. Typical refers to test data at the fiftieth percentile for a 25 Celsius room temperature.

Features common There are a number of features that are common to the E6474A platform software andto the E6474A platform that are available in all technologies. These features include the ability to record and

playback data sets, export the data to post-processing software packages, displayparameters on time charts and route maps and define flexible alerts and alarms, based onuser requirements. These features are detailed in this section:

View management Cell naming Report generator Call Statistics view GPS Data recording and playback Data export Link editor Measurement Parameters view Custom view Alarms view Time charts Route map view

View Management A view management tool is available to enable a reduced number of views to be presentedto the drive-test technician. Specific views can be selected or deselected for display.

Cell naming The phone-based measurements and receiver-based broadcast channel analyzer provide cellnaming features. The cell naming features are dependent on the user providing a text filedatabase with position and cell configuration information. Where the cell ID is known, forexample in the phone serving cell measurement, this is used to correlate with the cell name inthe database. Where no cell ID is known, for example in neighbor cell measurements orreceiver based measurements, a "best guess" algorithm is implemented. This algorithm makesuse of the geographic location, ARFCN and BSIC to attempt to determine which cell from thedatabase is the best match. The format of the cell database is text file with the following fields:

Cell name Longitude Serving ARFCN TCH ARFCN Latitude Cell ID Azimuth

A number of Cellsite database formats can be imported, including:- TXT, Agilent StationInfofiles, ICS, AXF, BXF, CDB, MDB, HP.

Report generator The E6474A system provides fast and easy report generation. The Report generatorcommand is available at any time during logging, Live Update mode, or when replaying adata file. All of the active views are captured, and an HTML document is created thatcontains a screen capture of each active view. Each report includes a header section anda dialog box prompts the user to enter the header information listed below. Smart defaultsand persistent information are used (marked *), so minimal text entry is required. There isno limit to the number of reports that can be generated.

Header elements: Report title* User name Company Time* Date* Location* defaults to current GPS fix Comments user entered notes

30

Call Statistics view Call Statistics are displayed in the Call Stats view. The Call Stats view shows the calltermination classifications and counts, and call progress messages. For a system withmultiple phones, each device is represented by its own column.

Parameter link editor This feature allows phone and receiver parameters to be linked to allow commonmeasurement criteria to be tracked on the display.Examples:

Link a phones carrier channel to its adjacent channels, provided by the scanner/receiver.The carrier and adjacent channel signal are displayed graphically in the AdjacentChannels view. Note: You can link up to 10 phones with their adjacent channels.

Link scanner/receiver channel measurements to phone channels/bands. Link CDMA scanner/receiver PN measurements to the phones PN increment. Link PN scanner measurements to GPS lock conditions. Link phone neighbor lists to scanner/receiver inputs.

32

Measurement Parameters view The Measurement Parameters view is an Explorer-style view of the system devices andtheir measurement parameters. When a data stream is required for entry into a dialogbox, the Measurement Parameters view opens, enabling the user to select a parameterand automatically generate the data stream required.

The Measurement Parameters view is initiated by the Alarms view, Time Chart view andRoute Map view, as described in the following three sections.

Figure 10. Measurement Parameters view

Custom View Custom view gives the user flexibility to create customized views by selecting parametersrequired and displaying them in a tabular format. Up to 40 parameters can be applied perview and multiple views can be created and saved for reuse.

Alarms view The Alarms view is used to configure alarms that are triggered by parameters receivedduring a test that meet user-defined criteria. Parameters collected as integer values ormessages, from connected phones, receivers or GPS navigation hardware, can be used toinitiate alarms; these parameters are selected using the Measurement Parameters view.The user can choose any one or all of the following actions to occur on an alarm:

A .WAV audio file can play A marker can be written to the database file, and displayed in the Route Map and Time

Chart views A pop-up message box can be displayed Measurements can be paused or stopped

Each alarm event is also tabulated on the Alarms view as it occurs. Fifty pictorial surveymarkers are available to depict alarm events within the Chart and Route Map views.Alarms require set-up prior to a database collection in order to enable survey markersduring playback.

The Alarms view enables the user to create simple or complex conditions to trigger analarm. The following are examples of how an alarm can be generated:

Monitor a single parameter for a single set of criteria. When the criteria are met, an alarm isgenerated.

33

Monitor a single parameter and logically "AND" up to five sets of criteria. When all sets ofcriteria are met, an alarm is generated.

Monitor several parameters, each with a single set of criteria. Each parameter can generateits own sound when the criteria are met.

Monitor several parameters, each with multiple logically "ANDed" sets of criteria. Eachparameter can generate its own sound when the criteria are met.

Monitor a parameter that is collected as a text message and generate an alarm when themessage changes.

Configure multiple instances of the Alarms view. Use one for each device.

Alarm configurations can be shared using export and import commands from the Alarmsview. These alarm configurations are stored as .MSF files. The E6474A software issupplied with over one hundred predefined .MSF files. By default these are stored atC:\Program Files\Agilent Technologies\Shared\Alarms. UMTS default alarms include hardand soft handoff alarms, low Rx power, high Io, potential missing neighbors, and SCpollution.

Chart view The Chart view is used to display measurements using a graphical display. Onceconfigured the user can see measurement information displayed relative to time, in bothlive and playback modes of operation. Up to 24 user-selected measurements can bedisplayed simultaneously, as four groups of six parameters. Multiple chart views can bedisplayed.

Figure 11. Chart view

The user-configurable options are initiated in the Chart view Properties dialog box.General Chart Properties enable selection of:Measurement averaging period, measurement update rate, x-axis (time) span,display/hide markers, display/hide legends and background, border and grid colors.

Specific Chart Properties enable selection of:Device and measurement series, y-axis max and min per measurement, chart displayon/off, y-axis scale display on/off, Draw method, Fill In Method and plot line colors.
