RM10 Wideband HF Modem and ALE

The Software Defined Modem (SDM) platform for the RM10 Wideband HF Modem and ALE was developed in response to the emerging Wideband HF Data Modem and ALE standards for strategic and maritime BLOS radio communications – specifically MIL-STD-188-110C and 141D.

The WBHF data modems are specified in MIL-STD-188-110C Appendix D, providing waveforms occupying bandwidths from 3 kHz to 24 kHz in increments of 3 KHz, and user data rates between 75 bps and 120 kbps.

The Wideband Automatic Link Establishment (WALE) or Fourth Generation (4G ALE) controller compliant with MIL-STD-188-141D Appendix G is used in setting up and managing WBHF links. The WALE controller provides fast and robust link setups by dynamically adapting the bandwidth and frequency offset of wideband channels to avoid interference and optimize throughput.

The UHF data modem is specified in STANAG 4691 Annex B providing user data rates from 12k8 to 96 kbps in a 25 kHz bandwidth. A RapidM proprietary VHF waveform offers user data rates up to 128 kbps in a 24 kHz bandwidth.

The RM10 is suitable for NATO Shore Station split-site operation, e.g. BRASS/BRE1TA
