Pilot Navigator07
Why Navigator?
Pilot Navigator is a simple yet robust analysis tool. All DingLi products utilize the same output format,
making data easy to process. Navigator offers an easy and highly scalable solution for benchmark data
analysis between different operators. It allows data to be reviewed and analyzed on any Windows-based
PC. Its comprehensive display allows for quick and easy decision making. Multiple data files can be viewed
simultaneously, allowing for a complete range of KPI reports.
Pilot FleetAutonomous Network Measurement Platform
Pilot Fleet is the solution for network operators and service providers who have a lot of benchmarking to do but few engineers to spare. It tests up to eight different 2G/3G networks simultaneously, while your key personnel monitor in real time from the office. No competing system offers such robustness or convenience in a single unit. Fleet represents the pinnacle of autonomous network diagnostic technology. It offers the most bang for your buck.
www.dingli.com09
Network operators are being squeezed between
increased competition, higher spectrum charges
and the effects of the credit crunch. Network build
costs must be incurred only when necessary.
The only certain path to operating profitably is
to maximize the performance of your network,
anticipate and correct faults, and remedy capacity
limitations before they affect customers. When
traffic loss and customer churn are minimized,
revenue and profits are maximized. The Fleet
autonomous testing system offers the shortest
route to an improved bottom line.
As a completely autonomous system, Fleet
operates around-the-clock collecting, processing
and analyzing of data from unattended Remote
Control Units (RCUs). A full-sized RCU can feature
up to eight integrated test modules, yielding a
load capacity of as many 2G/3G networks or
four independent internal MOS tests. Competing
solutions, which use flimsy commercial handsets as
test module substitutes, would require complicated
and cumbersome scaling to handle this workload.
Test data is both stored locally in the RCU and
uploaded to a central database for immediate
and subsequent processing. A subset of this data
consisting of vital performance parameters can
be accessed through the web client, enabling
immediate v isual izat ion of system status.
Competing systems, which cease testing during
data transmission, cannot be monitored in real
time.
Post-processing results, such as engineering
information, statistics and KPIs, can be manually
and automatically e-mailed to any desired address.
If results reveal something unexpected, further
measurements are not necessary. The data on-
hand can simply be re-analyzed more thoroughly.
Fleet is meant to measure once and process many
times. Costs from unscheduled drive tests need not
be incurred.
Fleet is a state-of-the-art platform that is
compatible with GSM900/1800/1900, GPRS/EDGE,
CDMA IS95A/B, CDMA IS2000 1X/EVDO, TD-
SCDMA and UMTS/HSDPA technologies. RCUs
are available in Standard (8X) and Mini (3X) form
factors, both of which feature the same real-time
data transmission capabilities. The Standard unit
is DC powered and is intended primarily for drive
testing, while the AC-powered Mini RCU is more
suitable for indoor use. Both can be configured for
any combination of 2G or 3G modules and scaled
for any workload. Regardless of your location,
technology or future plans, Fleet will meet your
needs.
How it works
RCUNumerous RCUs (Remote Control Units), each with
a specified combination of modules, are deployed
in any vehicle (car, bus, truck, boat, etc.) or
mounted in static locations. They are programmed
to collect network data from handsets, cells and
external scanners. All data is stored locally in log
files and transmitted automatically to the central
server. RCU configuration, service tested, data
collected and data upload method are defined by
the user via simple web client setup screens.
Web ClientThis software allows users to perform all system
functions from any terminal, anywhere. Test
plans and tasks that define RCU operation and
post-processing of collected data, followed by
report generation and distribution, can be carried
out through the client. Post-processing can be
performed automatically or manually or both. A
monitoring and maintenance screen shows the
real-time status of all system hardware elements
and allows setup of automatic e-mail distribution in
case of any major system alarm.

InsightAutonomous Network Optimization System
Your network gains users by the day, but competition fiercens by the hour. As your architectural complexity grows, the margin for error shrinks. In fact, it is gone altogether. The very network services you offer are the route to your undoing. Complaints become infamy at the speed-of-blog. Issues can no longer just be resolved; they must be avoided. Traditional KPIs, which indicate problems after they occur, are inadequate in this brave new world. Issues must be resolved while they are still latent, before they affect your bottom line. Insight is what we offer.
www.dingli.com17
Pilot Insight is the solution for GSM/UMTS network
design and optimization. It is an autonomous
network optimization system that acquires and
analyzes bulk data through the A, Abis, C, D, E, F,
IuB, Iu-CS, Iu-PS, Gb, Gi, Gn, Um & Uu interfaces
and displays it comprehensively, making it an ideal
aid for Customer Experience Management.
Insight is a measurement tool, but it is primarily
a number cruncher. It analyzes bulk network data
and determines patterns and trends that would
be overlooked by conventional diagnostic tools.
It detects not only flaws but the weaknesses that
precede them, allowing you to nip potential issues
in the bud. Insight gathers all the little details
together to illustrate the big picture and vice versa.
When an issue does emerge, the system collects
signal data in real time and stores it so that
operators can determine the exact metrics and
messages relevant to user complaints. This
enables a real-world picture of such complaints,
more precise than what a simple alarm could
offer, which will allow you to fine tune your network
experience by minimizing nuisances such as
interference, neighbor cell handover and dropped
calls.
Insight operates around-the-clock in your
equ ipment room, runn ing network tes ts,
troubleshooting and digging deeper into problems
and their causes. Insight clearly and concisely
illustrates RF dynamics, enabling engineers to
better plan and optimize your wireless network
services and resources.

interfaces, including Um, Uu, Abis, A, C, D, E, F,
Gb, Iub, Iu-CS & Iu-PS, which enables a true end-
to-end illustration of the call process.
- Precision: Network condition evaluations are
accurate to the carrier level.
- Optimization: Enables operators to move from
passive complaint response to active resolution of
latent vulnerabilities.
- Efficiency: Enables optimal allocation of finite
network resources for various services.

local coverage geography. Holes, weak zones and
overlaps stand out clearly.
Network Evaluation- Insight calculates and displays key performance
indicators that customers actually perceive, such
as coverage rate, call establishment rate, call drop
rate and voice quality, allowing network operators
to improve their QoS accordingly.
Neighbor Cell Optimization- MR analysis helps facilitate optimization through
hidden neighbor identification.
Insight Functions
Insight19
Insight Functions (cont.)
Overlapping Coverage Analysis- Insight employs an algorithm that determines
overlapping coverage zones, based on MR data,
which allows operators to better utilize their BTS
RNC resources.
RF Interference Analysis- Insight evaluates radio frequency interference and
identifies the most and least optimal channels.
Compatibility w/Drive-test Data- Insight combines drive-test data with interface
data from other areas of the BSS/UTRANnetwork,
enabling true end-to-end analysis.
Data Mining- Insight retrieves bulk data from virtually all network
interfaces, for in-depth & integrated analysis. Its
high-volume capacity enables the detection and
resolution of issues in areas of network stress,
such as train stations, outdoor events and office
buildings.
Alarm Triggers- Custom alarm triggers are available for customer
query and analysis; they can be exported for an
overall perspective of network performance, events
and user habits/characteristics.
Data Service Analysis- Insight analyzes data services using OMC and
Gb interface signaling information. It monitors the
Gb frame-relay link so that all signal and service
data packets sent between the UE and SGSN are
obtained for analysis.
Configurations
The Insight system can be scaled & implemented
in virtually any configuration. Individual units can be
portable or stationary.
Mobile Unit- Functional modules for the acquisition, synthesis,
storage & analysis of data are enclosed in a single
compact unit, which can be easily moved to any
site.
Full Network Solution- The Full Network Solution is intended for long-
term monitoring of networks with a large user base
and extensive infrastructure. Bulk data is processed
and analyzed so that the nature and cause of a
network problem can be accurately traced and
efficiently resolved.
ExploreNetwork Planning & Optimization Platform
Network optimization is an onerous, ad hoc ordeal. Inputs are diverse, disorganized and poorly integrated, leading to vast amounts of incompatible data that is difficult to backup and inefficient to process. This lack of standardization makes the process slow, both to do and to learn. Hours are spent each day collecting data, preparing reports and repeating calculations, tasks that are better suited a machine. That's where Explore comes in.
www.dingli.com21
Explore is an RF network optimization platform that automates key elements of the optimization process,
delivering greater speed and accuracy than ever before. Explore's key function is frequency allocation,
simulated and actual, on the scale of a cell, station, region or network.
Explore significantly reduces the grunt work involved in optimization, which gives engineers time to inject a
little creativity into the process. Explore automatically chooses an optimal frequency allocation scheme based
on the available data, while its simulation functions allow engineers to check out their hunches and hone their
skills .
Explore Benefits
Reduced HR CostsExplore reduces your HR costs by streamlining
the troubleshooting and optimization processes.
Up to 80% of your optimization team's man hours
may be spent on data collection, post-processing
and report generation; Explore automates all three
tasks, reducing the time involved from hours to
minutes, while its MTR analysis functions enable
timely resolution of uplink signal problems,
reducing the need for drive testing.
Timely Problem LocationExplore integrates previously disparate elements
of the optimization process, greatly reducing the
repetition and legwork involved. Its frequency
allocation functions integrate tasks such as BTS
frequency selection, carrier expansion/reduction,
frequency point replacement and BSIC planning; its
call analysis functions include voice call searching
& diagramming, handover performance analysis,
peak value highlighting, resource uti l ization
evaluation, and monitoring & template configuration
for most of these elements. A breakpoint
calculation feature, which saves computational
progress automatically upon interruption, allowing
later resumption from the same point, minimizes
repetition and wasted time.
Improved Network QualityExplore's superior operational and computational
accuracy leads to a better running network. A
reliable model for network frequency allocation
is enabled through Explore's processing of
measurement report (MR) data retrieved from your
network's operational support system. Compatible
OSS systems provide combined neighbor cell BCCH
& BSIC measurements. When active, an MS reports
the strength of the relevant serving cell signal along
with those for its six strongest neighbors, for which
the BSIC is decoded. Measurement reports are sent
over the SACCH every 480ms and can be stored
and post-processed so that potential interference
between any cell-pair in a network is determined.
By manipulating active BA lists and storing
measurement reports sent by active handsets to
the BSC, cell relationships (defined or undefined)
can be obtained. These Inter-Cell Interference
Matrix (ICIM) elements function as input for Explore.
Measurement-based data obtained in this manner
is more accurate than what traditional radio wave
propagation models would offer.
Frequency allocation modeling accuracy is also
enhanced through Explore's incorporation of the
Genetic Algorithm, a search heuristic designed to
mimic natural evolution that has proven useful for
real-world system optimization in fields as diverse
as bioinformatics, chemistry, computational
science, economics, engineering, manufacturing
and physics.
Enhanced User ExperienceExplore delivers clear, significant improve-ments
in the KPIs that matter such as interference,
handover, uplink & downlink quality, random
access success, establishment & drop rates, BER
distribution and complaint tallies.
System Applications
Data Acquisition and SharingNetwork optimization analysis typically involves
massive amounts of data, including traff ic
statistics, network parameters and measurement
data (such as BAR, MRR, RIR, etc.). If manual
collection is needed, it will require at least three
hours of an engineer's time, while processed
data cannot be shared by multiple users; Explore
remedies that situation.
Traffic AnalysisYour Network Optimization Division probably spends
an hour editing statistical reports each day. Explore
can produce these reports in one minute. Explore
defines all parameters involved in traffic analysis
reporting, and can do so on the scale of a network,
region, city, cell, etc.
Carrier Expansion/ReductionCarrier expansion and reduction are essential
to network optimization. The working schedule
involved is often complicated by an excess of data,
including:
- Daily maximum statistical values for a certain
cell;
- Basic configuration data, such as base station
type, CDU type and transmitted information for a
certain cell;
- Tallies for cells that require expansion/reduction;
- Cell expansion/reduction solutions and related
frequency data;
To simplify the carr ier expansion/reduction
schedule, Explore intelligently facilitates:
- Auto-generation of carrier expansion/reduction
data, including tal l ies for carriers requir ing
expansion/reduction, traff ic volume, GPRS
application conditions & related hardware info;
- Auto-generation of frequency data for carrier
expansion/reduction based on collected data &
frequency evaluation.
Frequency PlanningFrequencies, local or network-wide, usually require
frequent adjustment. Explore simplifies & improves
the effectiveness of these processes without
disruption. During implementation for a certain
city-wide region, frequency adjustment, frequency
comparison analysis, consistency checks, carrier
repair and other efforts were all carried out without
a single customer complaint, while speech & MRR
quality, network traffic, call drop and handover KPIs
were all significantly improved.
Uplink Interference HandlingUplink interference can lead to poor speech quality,
dropped calls and call failure. Explore locates
this interference through its RIR analysis function.
It determines interference category by analyzing
the RIR wave, while locating it and determining its
range through GIS analysis.
Subscriber Complaint HandlingAfter repeated subscriber complaints of call failure,
an engineer will typically carry out a drive test
around the call origin; this is costly & inefficient and
also useless if the problem lies in the uplink signal.
Explore can locate these problem quickly, with
fewer drive tests, through MTR analysis.
Coverage Overlap AnalysisWhenever a network's capacity is increased,
coverage overlap becomes an issue. Explore finds
these areas through NCS, MRR and other analytical
methods, enabling optimization engineers to
modify antenna position and inclination in a timely
manner.

Neighbor Cell OptimizationEver-increasing network traffic makes neighbor
ce l lopt imiza t ion a ted ious but v i ta l task;
mistaken removal of a cell will probably lead
to call dropsand complaints. Explore's auto-
neighbor cell optimization function is practical,
efficient andefficacious. It involves analysis of
NCS, handover data, traffic data, parameter
configurations, site location, and other data
that leads to provision of reasonable, intelligent
solutions.
Parameter Management- Hardware details related to the site, containing
data transmission info, CDU type, number of
carriers, and site type, are listed in Explore's
statistical reports;
- Error Log and Faulty Log data can be utilized for
site hardware fault analysis;
- Explore's network parameter queries and
comparison functions enable timely parameter
alteration;
- Consistent verification and abnormal data
checking facilitate an orderly review of network
parameters, identical or adjacent frequencies and
identical BCCH/BSIC.
Explore is an efficient, effective and convenient network optimization platform that collects data in bulk.

more challenging activities;
- Explore has been designed from the ground up. The practical experiences & feedback from large numbers
of optimization engineers have been utilized in every element of its design;
- Explore has a small footprint; it can be implemented at no detriment to the user experience;
- Explore brings more variety and creativity into the optimization process;
- Explore's integrates a variety of other functions, making it an invaluable optimization aid.
Why Explore?
Pilot ScoutAutonomous Network Measurement Terminal
Autonomous solutions are the divas of the RF network testing world. They are highly sought after and capable of great feats, but they are also costly and cannot be bothered with less glamorous tasks. A multi-terminal RCU is overkill for individual network benchmarking and unsuitable for pedestrian testing. A handset solution is suitable for both but far from ideal; there are costs involved with the use of name-brand hardware. A simple, dedicated autonomous testing tool is what is needed; Scout fits the bill.

Optimal Scenarios
Pilot Scout is a first-of-its-kind autonomous
testing solution, compatible with all major 2G/3G
wireless network technologies. It is a pocket-sized
device that weighs less than five ounces and is
powered by most sources encountered in the field
(wall socket, car battery, USB). Scout is a single-
terminal device and delivers the best cost-per-
network tested among hardware solutions. It is the
single most affordable network testing device on
the market.
Scout is an extension of our Fleet autonomous
network testing platform; it downloads test plans
remotely (via Web Client) and uploads data (via
Wi-Fi) to a central server in real time, all without
test interruption. Users can directly monitor data
streams online or receive KPI updates by e-mail
or SMS (See p. 9-12 for more information on the
Fleet platform).
Drive-test BenchmarkingScout's agile form factor and DC compatibility make it suitable for vehicular benchmarking. Its dimensions
make it suitable for dashboard rigging or cabin recess storage, while its durable, lightweight chassis ensures
that it need not be attended.
Long-term Indoor DeploymentScout is inconspicuous, scalable and AC-ready, making it suitable for small-scale parallel and large-scale
serial indoor testing. Its smooth, near featureless casing is resistant to manipulation, while its black finish
keeps it from attracting the eye. It disappears very nicely amidst the other devices on a desk. Unplugging
is also not ruinous, as utilization of its battery immediately triggers an automatic warning through the Fleet
server.
Short-term Pedestrian BenchmarkingScout is smaller than some handsets and features a 4-hour battery life. Engineers can carry it on foot for
an entire morning or afternoon of benchmarking familiar ground, at less cost than a licensed engineering
handset would entail.

Why Scout?
Scout is the first of its kind; there is no competing autonomous solution that offers such simplicity, value and
ease of use. Scout is the latest extension of our Fleet platform, a proven system that has been continuously
refined since it pioneered the market nearly ten years ago. Scout is easy to implement; it is compatible
with most available power sources while SIM card changing is a snap. It is also a versatile solution; its size,
durability and capability make it suitable for virtually any modest benchmarking scenario. But most important
is its value; Scout is the most cost-effective network testing solution on the market.
