Improving HF Communications Now and in the Future Whitepaper.

July 25, 2017

NATO plans to move BRASS (Broadcast and Ship to Shore) HF services to the new BRE1TA (BRASS Enhancement One Technical Architecture) which was initially set out in 2008. There have been important technical developments since the BRE1TA vision was set out, in particular the work on Wideband HF (WBHF). There is also increased technical understanding and experience with some of the technologies associated with BRE1TA. This has led to a number of detailed technical discussions, such as those set out in the Isode White Paper [Architecture for IP Application Services over HF Radio: Point to Point, Multicast and Broadcast], which was written to support NATO BRE1TA planning.

A new whitepaper on the Isode website [From BRASS to BRE1TA: Improving HF Communications Now and in the Future] gives a higher level summary of what is going on, with the aim of providing an explanation to those interested in BLOS (Beyond Line of Sight) communication, but who do not have detailed understanding of HF technologies. The paper looks at BRASS capabilities and sets out what can be achieved beyond core BRASS with technologies that can be purchased today. This includes four of the five BRE1TA goals and a few capabilities beyond BRE1TA. Finally the paper considers capabilities that are anticipated, but are not yet ready to deploy. This includes the fifth BRE1TA goal of providing generic IP services over HF.
