Ladiya-IBS

Ladiya-IBS is intended to protect speech information circulating in the places where the owner of a cell phone stays in case of its unapproved remote activation to intercept via cellular communication channels.

The operating principle of the device is as follows. Cell phone handset is placed inside a pencil holder (short sound signal indicates the device is enabled). In case of unapproved remote activation of phone in interception mode there is only one give-away characteristic which is change in the electromagnetic field (i.e. mobile phone transmitter switches to unauthorized transfer). This change is recorded by the field indicator to give a command to automatically activate mini cell phone jammer.

Ladiya-IBS is silent, the activation of jammer is indicated by short sound signal every 5 seconds. After the session started the mini jammer is activated within the pause of 15 seconds.

"Intelligent" mode is implemented as follows. In case of acoustic ringing signal (handset beep, music, etc.), the  jammer is not activated.

Ladiya-IBS has automatic battery discharge control. The intermittent dual tone signal at a frequency of 2 kHz with a repetition period of 0.6 seconds indicates low battery charge.

 Built-in cellular communication suppressor            900/1800 MHz/3G

 operates in band

 Noise level at the handset microphone               at least 100 dB,

 such high magnitude is caused by the dynamic proximity to Ladiya
