2.3.2.1 Data processing method – Peak vs Aggregate

If the multipath components are significantly lower than the peak, their contribution will be negligible

and the aggregate will be the same as the peak. However, if one or more multipath components are

close to the peak component in power, its power combined with the peak component’s power will be

larger than either of them alone. In the case where a multipath component is the same strength as

the peak the aggregate will be twice the power, or 3dB higher than the peak. Thus, the aggregate will

always be the same as or larger than the peak.

As a practical matter, many multipath components are typically present in an urban environment,

where there are many surfaces (e.g., buildings) which can reflect the radio signal. By contrast, there

may be few or no multipath components in a rural environment.

The difference between Aggregate and Peak is variable. Probably the difference will lie in the range of

0 to 4 dB. If the multipath components are small, they will have no contribution and aggregate will be

equal to peak (0 dB difference). In the case above where one multipath is equal to the peak, the

doubling of power gives +3dB to the aggregate. There might be cases where two components are the

same strength as the peak and this would result in an aggregate +4.7dB relative to the

peak. Naturally, if another component becomes higher than the “peak”, it becomes the new peak.

Aggregation does not happen over time, but over multipath components that are all simultaneously

present.

waveform has been divided into three segments (Segment 0, 1 and 2). The allocation of frequency

sub-carrier into these three segments is done in such a way that e.g. a downlink signal on segment 0

will not interfere with the downlink signal on segment 1. In a Reuse Factor 1 measurement,

contributions from all the three segments are considered in the measured parameters, so that the

CINRs are calculated from all the three segments. When Reuse Factor 3 is selected, only thecontribution of the desired segment is considered, and the CINRs are calculated only from the same

segment. As a broad guideline, measurements performed with Reuse Factor 1 will provide the signal

quality of the all the detected preambles relative to each other, whereas the Reuse Factor 3 category

of measurements will provide the signal quality of preambles within the same segment.

3.4.2.1

Data processing method – Peak vs Aggregate

If the multipath components are significantly lower than the peak, their contribution will be negligible

and the aggregate will be the same as the peak. However, if one or more multipath components are

close to the peak component in power, its power combined with the peak component’s power will be

larger than either of them alone. In the case where a multipath component is the same strength as

the peak the aggregate will be twice the power, or 3dB higher than the peak. Thus, the aggregate will

always be the same as or larger than the peak.

As a practical matter, many multipath components are typically present in an urban environment,

where there are many surfaces (e.g., buildings) which can reflect the radio signal. By contrast, there

may be few or no multipath components in a rural environment.

The difference between Aggregate and Peak is variable. Probably the difference will lie in the range of

0 to 4 dB. If the multipath components are small, they will have no contribution and aggregate will be

equal to peak (0 dB difference). In the case above where one multipath is equal to the peak, the

doubling of power gives +3dB to the aggregate. There might be cases where two components are the

same strength as the peak and this would result in an aggregate +4.7dB relative to the

peak. Naturally, if another component becomes higher than the “peak”, it becomes the new peak.

Aggregation does not happen over time, but over multipath components that are all simultaneously

present.

The PcTel MX can be configured in up to five different ways with MISO only, MIMO only, or a

combination of both. Multiple-band antenna ports are used for MISO only and are arranged in rows of

two ports. Single-band ports may be used for either MIMO or MISO and are arranged in rows of four

ports. In all cases, each band is assigned to a particular antenna port. The antenna connectors on the

SeeGull MX are male SMB A (screw-on) type. For MISO radio systems, antenna ports RF1 and RF3 are

high band ports supporting up to four bands each in frequency ranges from 1500 MHz to 2600 MHz.

Antenna ports RF2 and RF4 are low band ports supporting up to four bands each in frequency ranges

from 700 MHz to 1000 MHz.

The label on the SeeGull MX lists the frequencies of the radio modules connected to each specific port,

labeled RF1 to RF8. The antenna ports that require antenna connections are identified by their

“frequency” on the label. Since each SeeGull MX is configured to minimize the number of ports

necessary for use, some ports may be inactive for a particular configuration and are indicated by a

blank box.

Example 14.6.1

The SeeGull MX as shown in the figure below is configured for the following bands: 2100 AWS, 1900,

850, and 700 MHz bands on a standard MISO radio system. Either an OP216 (1700 to 2600 MHz)

antenna or an OP078H (698 to 2300 MHz) antenna can be connected the RF1 port. The OP078H is

recommended in this case to keep all the antenna types. Another OP078H antenna must be connected

to port RF4 (700 to 1000 MHz) to service the 700 and 850 MHz bands. Antenna ports RF2 and RF3 are

not used in this example and do not require antenna connections.

Example 24.6.2

The SeeGull MX as shown in the figure below is configured for the following bands: 2600, 2100, 1800,

and 900 MHz bands on a standard MISO radio system. An OP216 (1700 to 2600 MHz) antenna must

be connected to the RF1 port to handle the 2600 band. Either an OP216 (1700 to 2600 MHz) antenna

or an OP078H (698 to 2300 MHz) antenna can be connected to the RF3 port. The OP216 is

recommended for out of USA applications to keep all the antenna types the same since higher bands

are more prevalent in Europe and Asia. The OP078H antenna must be connected to port RF4 (700 to

1000 MHz) to service the 900 MHz band. Antenna port RF2 is not used in this example and does not

require an antenna connection.

Figure 5. MISO radio system configured for the European bands.

Example 34.6.3

The SeeGull MX as shown in the figure below is configured for the following bands: 2100 AWS, 1900,

850 MIMO, and 700 MHz bands on MIMO and MISO radio systems. Similar to Example 1, either an

OP216 (1700 to 2600 MHz) antenna or an OP078H (698 to 2300 MHz) antenna can be connected to

the RF1 port. The OP078H is recommended for bands used in USA for the purpose of having the same

antenna type. Since antenna ports RF3–RF6 are MIMO antenna ports, each port requires its own

antenna. Since the bands on RF3-RF6 are 850 and 700 MHz, the antenna type required is the OP078H

for each port. Note that MISO bands (700 A/B/C in this case) are allowed on the MIMO radio system

provided an antenna is supplied for each RF port. Antenna port RF2 is not used in this example and

does not require an antenna connection.

TOP-N Pilot scanning - UMTS4.10.6

Unknown Pilot scanning can be used for scanning unknown pilots or the strongest pilots. The Unknown

Pilot Scan will from now on be referred to as TOP-N Pilot Mode.

After the scanner is connected and activated in Nemo Outdoor, open the Measurement1.Properties dialog by selecting Measurement | | General Properties.

Go to the Pilot scanning page.2.

♦ Please note that the contents of this dialog depend on the scanner model used.

CP I C H Ec / N o t h r e s h o l d defines the minimum level for the CPICH Ec/No. If the values are below the

threshold, the pilots are not reported.

method, the sum of all peak pilot Ec/Io values above the PN threshold is calculated. If there are no

peaks above the PN threshold, value -30 dB is returned for WCDMA.

With GSM and WCDMA Layer 3 BCCH decoding, user can define the D w e l li n g t im e to decode the

messages. As defined in 3GPP standard SI, SIB, and MIB messages are broadcasted with different

periodicity. If the selected dwelling time is less than the periodicity of the SI, SIB, or MIB message

type requested, it will not be decoded. Dwelling time is supported with PCTEL EX, MX and EXflex

scanners for GSM and WCDMA. With CX, for WCDMA only.

P i l o t m e a su r e m e n t m o d e defines the measurement mode for pilot scanning.

• In High speed mode scanning speed is higher but sensitivity is lower. In high speed mode,

weak pilots may be undetected.

• In High dynamic mode scanning speed is lower but sensitivity is higher.

The available S am p l i n g r a t i o options are 1:1, 1:2, 1:4 and 1:8. With ratio 1:1 all samples (Pilotscan

events) are logged, with ratio 1:2 every second sample is logged, with ratio 1:4 every 4 th sample is

logged, and with ratio 1:8 every 8th sample is logged. By decreasing the sampling ratio you can

decrease the output file size, but the scanning accuracy will be diminished.

With S ca n n e r a v e r a g i n g you can configure the scanner to calculate average values for the samples

before sending them to Nemo Outdoor. With ratio 1:1 no averaging is performed, with ratio 1:2 the

average of two samples is calculated, with ratio 1:4 the average of four samples is calculated, etc. By

decreasing the scanner averaging value you can decrease the output file size, but the scanning

accuracy will be diminished.

T o p - N option enables/disables Top-N scrambling code scanning. If enabled, scanner will report results

from N best scrambling codes. N um b e r o f p i lo t s field defines how many pilots are reported by

scanner in Top-N mode.

T im e o f a r r i v a l defines if the selected scanner will measure the time of arrival for each scrambling

code. The time of arrival value is relative to GPS time and is measured in chips.

D e l a y s p r e a d defines if the selected scanner will also measure the delay spread value (in chips) for

each scanned scrambling code. Delay spread is determined as the difference between the last and first

component to break the threshold set in PN Threshold.
