WIDEBAND HF HOUSE

The “HF House” concept has originally been presented in the STANAG 4538 specification (included as part of MIL-STD-188-141D Appendix C) as a set of standards for HF communication. It attempts to align the NATO standards with the US MIL-STDs to promote interoperability. The HF House covers the lowest levels of the standard OSI Network model. It provides as a minimum baseline for achieving HF communication interoperability. Interoperability can only be achieved via standardization, followed-up by interoperability exercises between vendors.

An update to the HF House is required as HF Standards are continuously being developed. The addition of Wideband HF Modem, Wideband ALE and Wideband ARQ standards to the HF House concept is depicted below. The updated HF House is named the “Wideband HF House”.

Figure 1: Wideband HF House

The Wideband HF House shows the second (2G), third (3G) and fourth generation (4G) standards. The updated house also highlights the possible interactions between the Modem, ALE, ARQ and 2G, 3G & 4G standards.

The extensions include the following:

  • MIL-STD-188-141D (4G ALE)
  • MIL-STD-188-110C & D (Wideband HF Modems, Contiguous)
  • STANAG 5066 (WB ARQ)

The S/W architecture of a 4G implementation caters for concurrent LSU decoding and for the management of 2G, 3G and 4G linking, sessions and traffic. This means that:

  • 4G ALE systems can set up links for legacy narrowband or wideband traffic.
  • 4G ALE systems are backwards compatible with 2G/3G ALE. To this end 4G ALE/WALE supports a scan rate compatible with 3G systems.
  • STANAG 5066 WB (Edition 4*) is the appropriate ARQ for MIL-STD-188-110C, D.
