There’s no limit to Observing the Frequency
Environment – with LS OBSERVER
In line with the ever increasing use of wireless devices the radio spectrum is becoming congested and
its value increases. Efficiency in spectrum management is key, if you want to maximise the use of frequencies.
Spectrum regulators and operators alike need to permanently “monitor” the real use of the
entire spectrum to identify and locate both unused, underused frequencies and interference in order to
effectively manage spectrum.
One of the problems of conventional monitoring
systems is the question of where to locate them.
In addition, traditional monitoring stations often
produce too little data or have the wrong location
with respect to the area or frequency monitored.
Regulators set up measurement campaigns for
different frequencies over a certain period of time
in the hope that what they measure is needed for
future policy making. But who can look into the future?
Has it ever happened that the spectrum data
How does it work?
Store huge amount of data over a long period of time
You can “observe” the complete frequency range
and carry out detailed analysis on raw spectrum
observation data that is stored for 30 days. The
system then automatically compresses and stores
the entire observed spectrum throughout the tuning
range of the attached RF front, while noise and
zero occupancy are removed. You can store the
compressed data for about two years. Save on
a costly and complex backhaul solution with the
data being stored within the remote monitoring
unit.
ITU compatible
you collected during a campaign did not fully cover
the band you now need, requiring you to undertake
a completely new monitoring exercise?
This is where LS OBSERVER comes in.
LS OBSERVER monitors the entire frequency spectrum
and captures everything all the time.
You can monitor everything the whole year through.
Whatever monitoring data you need, you have it in
your system and you can retrieve it easily for instant
intelligent decision making later.
Intelligent software will sort out the necessary
information. Only the data required for analysis
is transferred to the central server. You can retrieve
exactly the data you need with the help of
search filters. This is why only little infrastructure
is needed to connect to the RF front end device.
In addition, the transferred data is stored on the
central server and, if needed once more, does not
have to be retrieved again from the monitoring unit.
LS OBSERVER next generation monitoring hardware and software solution is, of course, compatible
with all the monitoring guidelines and recommendations in the ITU spectrum monitoring handbook.

Cost Effective Investment &
No Barriers to Entry
Cost Saving through Flexible Design
You do not need a full network of identically specified stations. You can scale your RF front end exactly
according to the capability you need and the budget you have available by choosing from a variety of
receivers, sensors and spectrum analysers. The modular design with COTS products allows for easy
field maintenance. You can also save on initial investment by integrating your existing system into the
LS OBSERVER. Start with a stand alone system and finish with a national network by gradually building
up remote monitoring units. We can change or update your RF front end to ensure a future proof network
and to adapt to your changing requirements. We also build in redundancy and fail over according to your
needs.
Small & Smart instead of Big & Beautiful
As opposed to traditional very heavy monitoring equipment, LS OBSERVER RF front end devices have
a very small footprint and allow for “single pole” mounting. Permission to install these small and smart
devices is easily obtained.
They can literally be installed anywhere which means that many more site locations can be considered
for their installation. You can use, for example, 3G or 4G sites, too. Only two people are needed to set up
the LS OBSERVER device where five people are necessary to install a conventional monitoring station.
Flexible Connectivity of Remote Sites
The backhaul connectivity needed can be scaled to use whatever is available from low bandwidth PSTN
or VSAT connection through to high bandwidth point-to-point links. No longer do you need to base your
decisions on where to place a station on the connectivity available locally. As there are no special mast
or other site requirements, sites can be relocated easily and cheaply. You can quickly place mobile and
temporary stations, due to the low power and network connectivity required.
Flexible System Configuration according to Your Needs
LS OBSERVER can be used as a standalone system with simple single user access for direct user interrogation
of monitoring units or in a fully redundant virtualised server environment. The central management
unit manages all attached remote monitoring units’ health, configuration, security and network
availability. The server-client architecture allows for integration of both desktop and remote users on
either fixed or wireless connections.
Top-Class Solution: Integration with
Spectrum Management Systems
Integrate LS OBSERVER with a spectrum management system, such as SPECTRA, for easy automated
analysis of spectrum usage, automated licence and channel validation, report generation and quick
identification of illegal use or interferers.

Spectrum Policy Making
As a regulator you ensure that spectrum is managed and used efficiently. You have to justify to the
public that people get the best from their communications services.
Evidence-based Regulation
Whether you need to reform your frequency plan,
re-allocate frequencies or organise spectrum auctions;
you need real world data to establish your
business case.
LS OBSERVER provides you with long-term historical
measurement data for spectrum policy analysis.
You are in desperate need for spectrum to
attribute to a new service? Retrieve the relevant information
on usage from LS OBSERVER and check
whether a licensed frequency band is really used
to its full extent. You may consider it worthwhile
to pay to exit a user of an under-used frequency
and attribute it to someone else making better use
of it. Optimise frequency management and use
through evidence-based regulation.
Don’t miss a thing
LS OBSERVER “notices” even the shortest of taxi
conversations. Much faster than traditional
systems that often revisit a channel only every
few minutes and miss lots of transmissions. The
meticulous information on real frequency use that
the system provides you with, helps you clear up
even the tiniest misuse of frequencies, manage
frequency white space more efficiently and
increase revenue from licensing.
Geo-Location
Correct Your Licence Data
Do you agree that for efficient spectrum management
and use, you need to know what’s really going
on in the spectrum environment? That it‘s not
enough to have a well-managed and well-functioning
licence database?
It is essential that your license data is accurate.
Often, licence and frequency data in the database
are not more than 70% accurate compared with
measured spectrum occupancy. In order to increase
revenue from licensing you need exact, longterm
monitoring data to make sure your licence
data and licensing framework is optimised.
With LS OBSERVER you can measure real spectrum
occupancy the whole year through. Connected
to a spectrum management system, you can
compare measurement data with licence data in
your database and optimise your licensing.
Locate illegal transmitters in cities
It is in cities, where you are most in need of eliminating illegal frequency use. This is where spectrum is
congested, where you have to ensure its optimal attribution and where illegal use causes greatest
interference. Therefore a great advantage of geo-location over direction finding is that it enables you to
locate illegal transmitters in cities and to take enforcement actions. As high buildings distract the signal
from its original path, transmitters cannot be located through direction finding which is based on triangulation.
