Isode at High Frequency Industry Association (HFIA)

Isode CEO, Steve Kille, will be presenting at the next meeting of the HFIA in Munich on 14 September. 

The talk "Performance measurements of STANAG 5066 and Applications Running over STANAG 5066" follows a series of whitepapers published on the Isode website over the last couple of months looking at the performance of messaging protocols and applications over HF Radio:

STANAG 5066 Performance Measurements over HF Radio

This white paper sets out the results of measurements done by Isode of STANAG 5066 over military HF Modems and emulated HF Radio. These test show that good line utilization can be achieved (83-94 %) for speeds ranging from 75 bits/second to 9600 bits/second. To achieve this, care must be taken with how the application uses STANAG 5066.

Performance Measurements of Messaging Protocols over HF Radio

This white paper sets out and analyses the results of a measurements of various messaging protocols over HF Radio. HF Radio has unusual performance and reliability characteristics, which has led to specific application protocols being developed. This paper finds that three of the four protocols analysed perform well. It concludes with a discussion of the best choice of messaging protocol for various types of deployment.

Performance Measurements of Applications using IP over HF Radio

This paper sets out the results of measurements made when running applications and layer protocols to support applications over IP via HF Radio using STANAG 5066. The goal of this work was to get a quantitative measure of the performance impact of using applications running over IP over HF Radio in comparison with applications running directly over specialized HF Radio protocols. This paper concludes that the performance impact of using IP is massive, with small message latency increase from at typical value of 6-20 seconds using applications optimized for HF to a smallest measured value of 89 seconds when using IP.
