    • HF-kommunikasjon i Arktis - analyse basert på målinger 

      Jodalen, Vivianne; Mjelde, Terje (2016-05-09)
      For Norges store havområder i nord, der ingen teknisk infrastruktur for kommunikasjon er tilgjengelig og geostasjonær satellittkommunikasjon gir dårlig dekning, forventes langtrekkende HF-radiokommunikasjon å bli en ...

    • Initial lab testing of IP messaging over the AN PRC-117F 

      Jodalen, Vivianne; Grønnerud, Ove; Solberg, Bjørn (2005)
      This report documents the preliminary testing of the STANAG 4406 (Formal Military Messaging) using IP over the Harris AN/PRC-117F radio. Functional testing and limited performance testing have been conducted in a short ...

    • NATO Narrowband Waveform (NBWF) - overview of link layer design 

      Jodalen, Vivianne; Solberg, Bjørn; Haavik, Svein (2011-03-28)
      This report is an updated and final version of a draft report distributed to the NC3B SC/6 AHWG/2 in September 2009. We have kept the same report number in order to avoid confusion. In coalition operations NATO has a ...

    • Nato standards for HF communications : an overview and technical description 

      Jodalen, Vivianne; Otnes, Roald; Solberg, Bjørn (2004)
      During the 1990's many STANAG's (Standard Agreements) on HF communications were developed and agreed upon within NATO. The standards cover the lowest layers of the OSI model containing radio functionality, modem waveforms, ...

    • Performance testing of STANAG 4406 (Military messaging) using IP over HF 

      Jodalen, Vivianne; Solberg, Bjørn; Grønnerud, Ove; Leere, Anton B. (2005)
      This report is the final summary of a test activity of Project 822 SIGVAT HF. The STANAG 4406 (Military Messaging) and its tactical protocol profile has been tested over an HF link supporting IP. The automated HF technologies ...

    • Romvær informasjon fra internet til nytte for operative HF brukere 

      Jodalen, Vivianne; Farsund, Bodil Hvesser; Jacobsen, Bjørn (2003)
      High Frequency (HF) communications at high latitudes can be extremely difficult due to ionospheric disturbances causing large variations of channel conditions. In order to establish communications during such conditions, ...
