OREANDA-NEWS. November 25, 2010. The Department of Radio and Communications Engineering at the Tallinn University of Technology is developing jammers for the Estonian Defense Forces.

The devices, which have already seen use on foreign missions in Afghanistan, make it possible not only to interfere but also intercept and detect the enemy's radio transmissions.

They also have civilian uses, such as improving wireless reception in shopping centers, reported ETV.

In principle the device scours the airwaves looking for transmitters that were not previously broadcasting.

Made by a small company Rantelon, the "jammer" comes in a portable backpack and onboard-vehicle model.
