RM10 Wideband SDM & ALE – 24 kHz | Radio Modem | HF and UHF Modem

RM10 Wideband SDM & ALE – 24 kHz

The RM10 is suitable for installation on naval and maritime platforms (surface, sub-surface and air) as well as NATO shore stations requiring a split-site operation, e.g., BRASS/BRE1TA and BRIPES.

The RM10 comes standard with the WBHF data modems that 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 RM10’s software suite also includes all the narrowband HF modems available in the RM8 product.  The importance of the 3 to 24 kHz wideband HF radio communications cannot be stressed enough as the availability of wideband radio channels will remain an issue.  There are many more 6 to 12 kHz radio channels available than the ones with higher bandwidths.

Wideband Automatic Link Establishment (WALE) or fourth generation (4G) ALE compliant with MIL-STD-188-141D Appendix G and H is offered in the RM10 as a software option.  The WALE/4G ALE controller provides both fast and deep WBHF link setup by dynamically adapting the bandwidth and frequency offset of wideband channels to avoid interference and optimise throughput. When the WALE/4G ALE software option is active, the RM10’s software suite also includes the 2G ALE and 3G ALE/FLSU functions. 3G ALE/RLSU functions will be supported in future.

In addition, the RapidM proprietary wideband HF packet data modems known as WB-RDL is offered in the RM10 as a software option.  The WB-RDL waveforms and protocols are integrated with the WALE/4G ALE controller for link setup and dynamic forward/reverse traffic channel bandwidth negotiation. The combination of WALE/4G ALE with the WB-RDL provide data communication in challenged channel (e.g., SNR < 0 dB, high-latitude, high interference) conditions.  Operations in littoral waters of countries permitting powerline modems experience extreme levels of man-made noise, necessitating the use of packet modes as the only means of communication.  HF packet data modems enable communication in high-latitude and Polar regions where communication with military and other platforms, via satellite, is difficult or unavailable.

The RM10 also offers as a software option, the standards-based UHF data modems as specified in the NATO STANAG 4691 Annex B, providing user data rates between 12k8 bps and 96 kbps in a 25 kHz audio bandwidth. These waveforms have been extended to also support a 20 kHz audio bandwidth as required by legacy V/UHF radios.

In addition, RapidM proprietary VHF waveforms, known as VHF-5 (3, 6, 9, 12, 18 and 24 kHz) are available offering user data rates up to 128 kbps in a 24 kHz bandwidth.

The RM10 is a member of the RapidM “Family 10” 19-inch rack-mount hardware products, including the RC10, RI10, RB10 and RS10 products, all sharing a common hardware platform enabling a long (20 year) product and spares availability period.
