Abstract :
This paper begins with a brief overview of HF data transport requirements leading to waveform design and interoperability considerations for the expanded bandwidths provided with MIL-STD-188-110C Appendix D Wideband HF (WBHF). Over-the-air (OTA) performance test results of the WBHF suite of data waveforms, focusing upon shorter data bursts used in Automatic Repeat-Request (ARQ) and networking applications. Test results described in this paper are restricted to WBHF data links using the shorter interleaver options, short and ultra-short. The paper reviews HF Internet Protocol (HFIP) and Subnet Relay performance over links between different geographical locations and varying power amplifier (PA) average output power levels. Finally, the paper outlines the challenges of multi-node networking over HF sky-wave links and recommendations for optimizing multi-node sky-wave network performance when all nodes cannot utilize a single HF frequency due to geographically diverse locations.
