LXDT-430 - Compact passive cell phone signal detector in 2G/3G/4G networks

Availability: In stock.



The presented compact LXDT-430 passive detector is a very sensitive specialized equipment that allows the detection and location of all devices communicating in 2G, 3G and 4G cellular networks. The product is ideally suited to the detection of mobile phones and GPS trackers both in buildings and vehicles. Thanks to the streamlined design, light weight and small dimensions, the device can be carried in a shirt or trouser pocket or in a holster attached to a belt. The detector is very easy to use, it has only two function buttons.

The passive LXDT-430 detector allows very precise adjustment of sensitivity (detection range) and thus it can be adapted to all working conditions. The detected signals and their strength are shown on the LED display and signaled by a sound, and in the silent mode by vibration or discreetly through the connected handset. The intensity of notifications depends on the distance from the signal source and its power. Our device literally takes 10-15 minutes to locate the GPS / GLONASS / GALILEO tracker hidden in the vehicle without our consent.

The LXDT-430 cell phone detector uses the passive receiver technology with the use of band-pass filter, which automatically detects all types of communication above the noise level on all cell bands simultaneously. Thanks to the built-in SAW filters, the detector is completely insensitive to signals from base stations, DECT cordless phones, DMR radios, walkie-talkies or other devices that do not operate in cell bands, and therefore does not cause false alarms. Thanks to the above technologies, our detector with detection efficiency exceeds competing solutions (mobifinder 4, mobifinder 5, iprotect, raksa) using an inaccurate frequency scanning method that does not always capture all signals.



The LXDT-430 tactical smartphone detector allows passive detection of all types of communication and technologies above the background noise level on all cell bands simultaneously, UPLINK frequencies ( Europe ):


Detected signal types:

- line signals on 2G network ( standby / sleep mode )
- voice connections on 2G / 3G / 3.5G networks
- video connections on 3G networks
- short text messages on 2G / 3G / 4G networks
- MMS multimedia messages on 2G / 3G / 4G networks
- packet data transfer - GPRS / EDGE / UMTS / WCDMA / HSPA + / LTE technologies - all 2G / 3G / 4G networks
- fast data packets in 3G / 4G networks, so-called burst transmission

Detected and localized devices:

- GSM / 3G mobile phones, GSM / 3G / 4G / LTE smartphones
- GSM / 3G / 4G wiretaps
- 3G / 4G cameras
- GPS / GLONASS / GALILEO locators with 2G / GSM / GPRS / EDGE / 3G / UMTS / HSPA + / 4G / LTE modules
- 3G / 4G modems / routers
- spyphone spy software activity



The device is also designed to detect communication in cellular networks in places and rooms where there is a categorical ban on the use of cell phones, smartphones, tablets and other devices communicating through the cellular network. The equipment is ideal to use in:

- schools
- an examination center
- a prison
- a detention center
- a correctional facility
- a government institution
- an embassy

Due to the high sensitivity and long range detection, the LXDT-603 detector can also be used in various types of rescue operations to search for people under debris or lost in a given area who have a mobile phone or GPS locator with them.


This product can be configured for frequencies used in any region around the world.
