Subscriber and device identification
IMSI and IMEI capture
Identify the mobile subscription and the handset through their cellular identifiers. This configuration does not include access to call audio or SMS content.
Multistandard SDR platform
Two-carrier radio hardware supports GSM, UMTS, LTE and 5G Non-Standalone. 5G Standalone is outside the specified compatibility of this configuration.
Separate expansion modules
The base package includes its laptop control station. RF amplification, direction finding and C-SCAN network analysis are available as separate options.
Full description
IMSI catcher with cellular service blocking
MULTI-CATCHER combines an SDR unit with laptop-based control software. It collects IMSI and IMEI identifiers from compatible mobile devices within its operating area and supports blocking access to regular cellular network services.
The IMSI identifies a mobile subscription associated with a SIM. The IMEI identifies the handset. Neither identifier is the content of a conversation or text message; voice and SMS interception modules are not part of this package.
GSM through 5G NSA
The platform supports GSM, UMTS, LTE and 5G NSA. Non-Standalone 5G relies on LTE infrastructure; it is distinct from 5G Standalone. Supported GSM, UMTS, LTE-FDD and LTE-TDD bands are listed in the specifications.
SDR hardware and control station
The SDR unit connects over LAN and operates from a 10–24 V DC supply. Average RF output is 2 W, with power consumption of 70–90 W. Its aluminum and plastic enclosure measures 200 × 140 × 40 mm and weighs 1.4 kg. These figures apply to the SDR unit, not the complete system.
Configure the system by function
The optional amplifier increases RF output. The separate GSM/UMTS/LTE localization unit provides handset direction finding. C-SCAN surveys the cellular network environment and organizes results on a map and in a cell database.
Each option adds a distinct capability. The base package includes system implementation and training, delivered online or at Endoacustica.
Optional modules

RF Amplifier
A wideband amplifier for the SDR unit, delivering approximately 80 W average output on 2G, 3G and 4G. It increases available RF power and can extend system coverage. Amplifier coverage is not specified as a fixed distance. The option includes the amplifier and cable set.

GSM/UMTS/LTE Direction Finder
The localization unit adds direction finding for GSM, UMTS and LTE handsets, with signal-level feedback. Operating distance is up to 500 m, depending on conditions. The compact 11 × 6 × 3 cm unit uses a 2 Ah rechargeable battery. An antenna is included with this option.

C-SCAN Cellular Network Analyzer
Survey 2G, 3G and 4G networks simultaneously without SIM cards. C-SCAN provides map visualization, a cell database, distance measurements, GPS functions and points of interest. The package includes scanner hardware, antennas, GPS antenna, USB cable, software license and a dedicated laptop.

Applications
Authorized agency investigations
Subscriber and handset identification for authorized government and law enforcement work. The supplied configuration handles identifiers rather than call audio or message content.
Handset location
The optional direction finder adds directional signal detection for compatible GSM, UMTS and LTE handsets.
Cellular network surveys
C-SCAN documents the cellular network environment using map-based results and a cell database, supporting technical surveys in the field.
Frequently asked questions
Does MULTI-CATCHER intercept calls or text messages?
No. This package provides IMSI/IMEI identification and cellular service blocking. Voice and SMS interception modules are not included.
Is handset direction finding included?
No. The GSM/UMTS/LTE localization unit is an optional module supplied with an antenna.
Is the 80 W amplifier part of the base system?
No. The base SDR unit has 2 W average RF output. The optional amplifier provides approximately 80 W on 2G, 3G and 4G.
Does it support 5G Standalone?
This configuration supports 5G NSA, which relies on LTE infrastructure. 5G Standalone is outside its specified compatibility.
Is 500 m the range of the IMSI catcher?
No. The up-to-500 m figure applies to the optional localization unit. It is not a coverage rating for the base catcher or the amplified system.
What does C-SCAN add?
C-SCAN scans 2G, 3G and 4G networks simultaneously without SIM cards. It adds map visualization, a cell database, distance measurements, GPS functions and points of interest.
Is training included?
Yes. The base system includes implementation and training, delivered online or at Endoacustica.
