Isode at the HFIA #1: Proposed Extensions to STANAG 5066

The High Frequency Industry Association (HFIA) provides an “industry driven forum for the interactive exchange of technical and information in the area of High Frequency Communications.” Physical meetings of the group usually take place twice a year and in September 2014 Portsmouth was the location for the latest of these meetings. This is the first of two blog posts covering our attendance at this meeting.

As Isode has an interest in applications for constrained bandwidth communications, we often attend and occasionally present at these meetings. This year we had two presentations to share with the attendees.

Isode CEO, Steve Kille, gave a talk focusing on Isode’s proposed extensions to STANAG 5066 to improve performance of applications running over wideband HF links. The first was an update to a talk Isode gave at the February HFIA meeting, this time including hard measurements showing that Isode’s extensions (known as LFSN, Long Frame Sequence Number) result in significant performance gains.

This was followed by a live demonstration of the extensions in action, enabling co-existence of bulk and time critical applications over narrow-band and wide-band HF. The applications used were Multi-User Chat and Real-Time Military Forms (both using the XMPP protocol) and military email messaging.
