Empowering train operators
in mobile network measurement
Tools, expertise, solutions

Holistic solutions
for train operators
Decent mobile connectivity on board
public transport is the foundation fortechnological developments and an
important element for people when
deciding how they travel. Done right,
it can lead to cost improvements, newpassengers and new revenue streams.
Subpar solutions, however, waste timeand resources and can even weaken
customer satisfaction if their real experience falls short of their expectations.
Focus Infocom provides you with thetools, resources and services you needto get a complete picture of mobile coverage and the user experience on board
trains or public transport in general. We
help create the expertise and data youneed to make solid investment decisions and deal with operators or suppliers of in-train systems such as repeaters
or Wi-Fi routers.

Whether you are taking your first steps
in this sector or you want to improveand expand on what you have alreadyachieved, we are here to support you
with our solutions.
Our service portfolio supports yourteam in the best possible way:
■ Delivery of tools and systems■ Task-specific campaigns■ Complete operation and ongoing
operational monitoring, processingof data
The resulting information is valuable
not only for your investment decisions
or the optimal use of your systems. It
also enables you to clearly communicate your requirements to suppliers andevaluate their offers.

Creating a solid
data baseSolid information is the basis for every
investment decision. We offer the tools
and expertise to reliably generate thisfoundation.

To this end, they perform the sameactivities as real users: making phone
calls, surfing the internet, watching
videos and using various apps.

The common basis of all solutions are
systems that provide insight into thequality of service from the passenger’s
point of view.

Depending on the type of information
you need, you can choose from a set ofbuilding blocks that together provide a
360° view of the connectivity on board.

Measurement types
QoS measurement

Fields of application

Permanent monitoring
The ACT family of autonomous measurement
systems is the ideal choice for permanent monitoring. The members of this family include special
systems certified for in-train usage and intended
for permanent installation in trains.

Permanent monitoring isbeneficial on highly frequented routes of great economic
importance with low tolerance to failures or degradationof performance.

Non-permanent or ad hoc measurements
Systems for these use cases can be flexibly
deployed. Recommended system types for thesefields of applications are:Non-permanent measurements are useful for initial
explorations, targeted campaigns, and occasional statusmonitoring.

■ Autonomous systems of the ACT family thatare not permanently installed.
■ XGMA SP interactive measurement tools invarious form factors, mostly in the form ofmulti-channel backpacks.
■ SPO smartphone-only autonomous systems
that can be used ad-hoc by anyone without
expert knowledge, for example train attendants: switch on and start measuring.

While the above types measure the quality of service
perceived by the user, load
measurements aim to create
information about the capacity of a network.

Load measurement
A load test uses multiple end-user
devices to investigate the effectsof concurrent use of networks andsystems (e.g. Wi-Fi routers) undercontrolled conditions.
■ Test the maximum capacity and examine the impact of high loads on
Wi-Fi routers.

External antennas

■ Investigate the concurrency behavior of connectivity through in-train
routers and mobile networks useddirectly by end user devices.
■ Evaluate how the individual user’s
service QoE changes with increasing
total load.

Getting the mostout of your data
Post processing makes your collected
data accessible and powerful, andvarious types of reports present thisdata in an easy to understand andversatile way.
Reports are mainly based on direct
measurement data, but can also include
diagnostic and status data from secondary sources such as on-board repeaters,
Wi-Fi routers and other systems.

You can also export data at the source
file, text table or database level forfurther processing and integration into
your processes.
We fully disclose our database formats
and structures to give you the freedomof choice for your specific use cases
without locking you in.

Internationally standardized KPIs
provide information about the key
characteristics of the system or network
under test.
In addition to “static” report documents
and presentations, we offer dynamic
reports based on Tableau™ that allow
users to interactively filter data, visualize
it geographically, zoom into maps withthe required resolution, and navigate
the information as needed.

Data reports generated with FIMAS (Focus
Infocom’s post processing suite), Tableau™ or otherreport generators provide in-depth insight into anetwork.

Extended andcustom metrics
Focus Infocom developed novel QoS
metrics that leverage the uniqueproperties of rail travel. These metrics
provide a holistic view of the enduser’s experience (QoE) for all types oftelephony, including VoLTE and OTT
services, and allow solid predictions fora variety of use case parameters basedon measurement data. By extending
the range of conventional QoS KPI, theydescribe the customer experience andtherefore the business value of goodconnectivity more accurately, andprovide improved guidance for networkoptimization.
These metrics were contributed tothe international standardization
community in ITU-T Study Group 12.
The standard, ITU-T Recommendation
G.1034, was approved by the ITU-T andis in force since January 13, 2020.

ACT Family
Focus Infocom‘s ACT family ofautonomous systems covers a wide
range of use cases and is available indifferent form factors. Custom designs
for individual requirements are possible.

Features■ Remote distribution of measurement jobs
■ Latest generation of smartphones■ Use of internal or external antennas,depending on use case
■ Certified for railway use (ACT Train)■ Multi-SIM switcher■ Mobile network and Wi-Fi measurement■ Numerous telephony and data testservices■ App-based tests (YouTube™, Skype™,Facebook™ etc.)■ Individual designs for installation indifferent train types■ Speech quality (POLQA, ITU-T P.863)

ACT SPO is a smartphoneonly autonomous measurement tool ideal for quick andeady ad hoc use even by nonexperts. It uses the internalantennas and delivers datafrom a user perspective.

ACT Train

Fleet Manager

ACT Train is a certified autonomous
measurement system for permanent
installation in trains. The probes can beinstalled in the passenger compartment
for measuring the user experience using
internal antennas for a true QoS view.
To measure the coverage along therailway network, the systems can beequipped with external antennas.

With its elongated shape, ACT Train is certified
for permanent installation in German trains.
For other countries, other form factors with
their own certification are possible.

The FleetManager is the heart andsoul of every ACT fleet. It gives you
full insight into the position and status of each system at any given time.
With the FleetManager you define anddistribute measurement jobs, update
systems, schedule jobs, set alarms andmore.
This allows you to plan measurementtasks for each box in advance. With its
visual interface, managing complex
tasks is done in a breeze. You can run
the FleetManager by yourself, but wealso have clients and projects where
we take care of hosting and operation.

XGMA SPXGMA SP is a powerful benchmark
system based on up-to-date Android
smartphones. With different shapes
and sizes XGMA SP adapts to multiple
use cases.
