The
TETRA AirAnalyzer developed by fjord-e-design can be used to record,
display and analyze the complex course of the communication between
a TETRA mobile unit and a TETRA base station. Since TETRA is a fairly
"new" standard the TETRA mobile and base stations of different manufacturers
are not always working smoothly together. An analyzing tool can be
very useful (actually it is necessary) to insure the operation of
TETRA systems.
With the TETRA AirAnalyzer it is possible to wirelessly monitor (via
antenna directly to the air interface) two frequencies simultaneously
with respect to the uplink and downlink (i.e. eight physical channels).
The result of the complex structure of the standard TETRA is a large
amount of data, which seems to be of unmanageable size.
The solutions to this problem are sophisticated protocol filters and
analyzing procedures, which are integrated in the TETRA AirAnalyzer.
They find problems regarding the signaling between MS and BS. The
TETRA AirAnalyzer is supplied with a high sensitivity of the antenna
( -115 dBm) and it is possible to fit a DC input into the device to
use it for mobile operation.
There is the new possibility to run the software independent
of the hardware with a computer to analyze i.e. the data stream out
of a TETRA base station. fjord-e-design offers an open interface format.
The work style with the software has not changed, the data input simply
works via another channel and got more flexible by the way.
Scope of use:
- Development
- Load tests
- Tracking
down lost signaling messages, calls, etc.
- Monitoring
and analyzing the signaling
