A tiny cellular radio no bigger than a music cassette will allow Europe’s police, customs and excise and other government agencies to talk to each other secure in the knowledge that no one can intercept their calls.
Developed by Racal Defence Electronics for the new Trans European Trunked Radio standard, or Tetra, the lightweight, waterproof radio has no knobs or switches and is ideal for covert surveillance operations. It can be hidden in a pocket and controlled by a small external keypad in the hand. It offers encryption of conversations all the way from one handset through repeater base stations to the receiving handset. If the radio is tampered with, it wipes out the encryption codes.
