M-Link & XMPP Performance Measurements over HF Radio using STANAG 5066 and IP

This paper describes and analyses measurements made operating XMPP over HF Radio, using HF modems and a simulated radio link. We look at measurements operating directly over STANAG 5066, and operating over IP.

The measurements show that good performance is achieved over HF using STANAG 5066 for a wide range of parameters. Operation over IP over HF gives good results in some situations, but is not generally recommended.
