Means for Radio Monitoring Indoor


This section covers technical means intended for search, localization and technical analysis of indoor unauthorized radio emission sources. Main users of such systems are law enforcement, overseeing, security agencies.


ARC-D13R and ARC-D15R systems function inside engineering structures, buildings or in zones of the monitored object and ensure revealing of unauthorized radio emission sources, including their identification and localization. They use remote modules – devices installed inside protected premises, to which wide-band antennae are connected. In turn, portable modules are connected to control units.


In ARC-D13R system, remote modules contain analogue radio receiving tracts, signals are transmitted to the control units on a low intermediate frequency, which significantly decreases the negative influence of long cable lines on the operation quality of the system.


In ARC-D15R system, the problem of the effect, produced by long cable lines has been solved drastically. The remote modules includes not only analogue paths, but also digital signal processing units. In fact, the remote module is a full-fledged digital radio receiver sending signals in the digital form. This enables using the standard network infrastructure for control and transmission of signals in ARC-D15R system. Without additional routers, the portable module is controlled within a distance of 100 m via the twisted pair, and within much greater distances via the optic cable.


Due to the use of portable modules that contain a digital processing unit, ARC-D15R system has a number of substantial advantages compared to ARC-D13R system, such as increased speed of operation, flexible scalability, advanced identification and localization of digital communication system radio signal and data transmission sources.
