Passive GSM interceptor GM-1
No longer produced

The system was designed in the the early 2000 
for the air 
interception
 for 
cellular 
communication
 in 
GSM
 networks 

The 
passive GSM
 interception
 system, designed
 
for mass interception of GSM targets only without using active components (BTS).
The receiver unit is designed on Motorola phone modules.
The system includes external decipher A5.1 and internal decipher A5.2 

The
 system can intercept 
A5.1 and A5.2 
encrypted
 communication. 

The
 system 
includes 
3 
main 
building
 blocks:

1. Receiving
 Units (each unit is only 8 channel) 
2. Notebook 

with 
interception 
software 
and, 
if 
needed,
 A5/2
 real time
 decipher.

3. A5.1
 Real 
Time 
Decipher.

The
 system
 is 
housed
 in
 a
ruggedized
 small
 unit 
(25X25X12
Cm) 
connected
 to 
the A5/1
 real
 time
 decipher
 either
 by 
a 
USB 
cable 
or 
wirelessly. 
The 
basic 
configuration supports
 interception
 of 
8 
full 
duplex 
sessions
 (intercepted
 by
 16
 receivers) 
from different
 base
 stations 
and 
different 
providers 
(configured
 by 
the
 operator). System
 is 
a 
quad‐band
 and 
can 
be 
tuned
 to 
any 
GSM 
frequency
 used 
in
 the 
specific area.

All
 intercepted
 sessions
 and
 related 
data
 are
 stored
 in
 the 
system
 data base
 for off
line
 analysis
 and
 playback.

System
 can 
operate 
with
 variety
 of 
power
 sources
 such
 as
 AC
 supply, 
generator, batteries, 
car
supply 
etc 
and
 by 
that, 
it 
can
 be
 installed
 and
 operated
 in 
many 
types of
 configurations
 and 
environments 
(fixed 
installation,
 remote
 control
 configuration, transportable, 
vehicular, 
man
pack
 etc). The
 architecture 
is 
modular
 and
 system
 capacity 
can 
be 
increased 
for 
interception
 of 16, 
24, 
32 
full 
duplex
 sessions, 
all
 supported
 by
 a 
single
 real 
time
 decipher.

At the beginning of interception, all existing receivers dedicated to forward channels must to be tuned to the nearest-to-target-phone base stations. Depending on its environment, a mobile phone can communicate with a GSM network via one of several preferred base stations located nearby.
In a rural environment or in a small town, there may be 1–2 preferred base stations. In such a case, a GSM Interceptor with 2 forward receiver channels may be enough. But in a big city, where base stations are close to one another, a mobile phone makes its choice among 2–3 or sometimes even more base stations. Then an Interceptor with at least 3 forward receiver channels will be necessary
.

In the picture above the mobile phone may choose among 4 base stations, so the Interceptor needs at least 4 forward receiver channels. If an Interceptor with 2 forward receiver channels is used in this situation, the chances of missing the call will be around 50%.
