German contractor Rohde & Schwarz (R & S) has announced that it has been awarded Terrestrial Trunked Radio (TETRA) system contracts by Russian crude oil supplier SIBNEF and the government of Austria.
Taking these in the order given, SIBNEF is to be supplied with a turnkey R & S Bick Mobilfunk Accessnet®-T TETRA mobile radio network to support the security of its trans-Siberian oil pipeline.
Commissioned at Nojabr'sk, Siberia during August 2002, the system incorporates TETRA exchanges and base stations that are interconnected by E1 lines and Ethernet connections that use routers supplied by Cisco/ComStore.
At the time of going to press, the network was understood to consist of two DMX-521 TETRA exchanges and seven TETRA base stations with over 30 radio-frequency carriers.
In the Austrian context, R & S subsidiary Bick Mobilfunk has been commissioned to supply Austria's new Austrian Digital Operating Network for Integrated Services (ADONIS) which is billed as Europe's largest ever trunked radio system. Valued at
190 million, ADONIS will incorporate in excess of 1200 TETRA transmitters and is compliant with security authority protocols concerning standardised and compatible trunked radio systems that are established as part of the European Union's Schengen open borders agreement.
