Hi,
GSM-test equipment for sale (usable for detection of unknown or hidden
GSM-devices)
I do have 2 pieces of second-hand GSM test-equipment
they can be used for the usual testing and repair
of mobile GSM-equipment (phones and modules)
1) Rohde & Schwarz CTS55 (my price: 2250 Euro's)
http://tinyurl.com/c7l4r
2) Willtek series 4100 (my price: 2000 Euro's)
http://www.willtek.com/english/products/tt/4100
Both units are intended for GSM repair-shops or
for production testing of units that incorperate
GSM-equipment.
Normal uses:
======
Normally the GSM-phones are connected to above test equipment
using a direct connection with a cable or with a special holder
with a built-in antenna.
Both units simulate a real network basestation
the phone under test will then make a connection with the simulated
network...after wich various tests can be made such as
requesting all kinds of data from the phone
(IMEI#,SIM-info,channels,powe...etc)
Both units come with a test Sim-Card wich simulates a network with
a non existing network code ...for example 001...this card must be
inserted in
the phone under test.
but any other real and existing network can also be programmed into the
test-equipment.
As a result above equipment can also be used to simulate your
(real)local GSM-network
without the need to insert the test-card into the phone under test
All you need to do is to insert the correct network-code(s) into the
test-equipment
these codes are wellknown...so no problem there.
The phone under test must be directly connected to the test-equipment
or it must be placed in a so called cradle wich is a special holder
with a built-in antenna...the test-equipment only uses very low-power
and has very low reception-sensitivity...therefore it will not work
when the phone is not directly connected or placed in the special
cradle
Other uses:
=====
Now...with some tricks above test-equipment can also be used for other
purposes such as:
"Off the air" measurements and grabbing of phone data !
By simply increasing the transmit-power and the reception-sensitivity
of the Test-equiupment
You will be able to:
A)
Lock a unknown GSM-phone to your fake basesstation !
B)
Grab phone-data "Off the air" up to a few 100 meters !
C)
Lock a GSM-phone to your fake base-station thus disabling
it to make a real call (the same effect as a jammer)
D)
Catch a dialed number from the target phone (without a real connection)
E)
Find hidden GSM-bugs,Spyphones and GSM-trackers
by simply presenting a valid network to the area under search,
you will then see the unknown phone presented on the screen of
the test-equipment
...etc...etc
It's up to your imagination.
If you you are good at this stuff you could even make a
real "IMSI-catcher" out of it (needs additional outgoing line)
In order to achieve these additional new uses...all you need to
do is increase the power-output and sensitivity of the
GSM-test-equipment
This can be achieved in various ways:
1)
By adding a transmit and reception amplifier
or
2)
By adding a so called lowcost "GSM-repeater" normally
used to increase coverage in "bad-coverage" or "in-building" areas
such a repeater is in fact the same as a transmit and reception
amplifier
only difference is that it is ready built.
Both units can also be programmed with so-called "scripts" wich will
allow them to do various functions in sequence.
Ready made scripts are freely downloadable from above manufacturers
extensive information is available to make your own scripts
and have the equipment do other things.
Script language is simple and exists of a series of commands that you
send
to the equipment.
Both units can be remote controlled from a standard PC
One example of such a script could be the automatic switching
of networks...you could do that by hand but automatic is nicer and
quicker
An example application could be:
Detection of unknown GSM-bugs in a room
===============
You place the equipment in a room...the unit will quickly present
itself
as all local networks (in sequence) and show any unknown GSM-devices
Voila...now you have a GSM-detector that will reveal all GSM-bugs
even when they are not active (sleeping)
Ofcourse you have to know what you are doing
Detection of unknown GSM-devices in a car
================
Even better do-able then detecting GSM-bugs in a room
since you have a very small area to search.
You place the car in a "faraday-cage" then you place the
test-equipment in side that cage....a possible GSM-device
will then lock to your simulated basestation and give itself away
If no Faraday-cage (screened room) is available you could do without
or drive the car to an area with low GSM activity (levels) and do the
test there
As said many new possibilities...i you are interested please read all
information
and user-manuals first....in order to understand the possibilities.
There is an other unit available (wich i don't have...and at a much
higher price)
it's called: "willtek 4208 Off-Air Mobile Tester"
it can do all i have mentioned above
http://www.willtek.com/english/products/tt/4208
You can do the same with the second hand equipment i offer here
just a few mods are needed...(if wanted i can do those for you at extra
cost)
Prices are ex TAX and transport,availability is 10 days
you may contact me private.
Update
===
...the CTS55 is sold..but i could get another one...either new or
second hand
probably it will be more expensive...the Willtek series 4100 is still
available.
