RM12 — Wideband SDM & ALE (48 kHz)

RM12 Product Overview

Navies and coast guards need relatively high speed beyond line-of-sight (BLOS) data communication, spanning long distances over water, without being reliant on satellite networks. High frequency (HF) backbone networks and other terrestrial HF radio networks provide strategic communications to government, disaster relief agencies and industries, without relying on vulnerable fixed-line network infrastructure.

Wideband HF Streaming Modem

Offering data rates of up to 240 kbps on a 48 kHz wide channel, the RM12 opens the door for HF to provide the same levels of data transmission speeds, quality and security of a narrowband SATCOM system. The RM12 offers standards-based HF data modem waveforms, in particular, the 48 kHz wideband HF modem as defined in MIL-STD-188-110D and STANAG 5069. Included with the wideband data mode, the suite of SSB and 2-ISB waveform, defined in HF MIL-STD-188-110A/B, STANAG 4539, 4415, 4481, 4285, 4529 and 5065 (LF) allows interoperability with legacy systems.

Wideband ALE

The RM12 also provides wideband automatic link establishment (4G ALE/WALE), based on MIL-STD-188-141D, up to 48 kHz bandwidth. The 4G ALE/WALE option includes 2G ALE and 3G ALE as per MIL-STD-188-141A/B and STANAG 4538 (FLSU only). Please refer to the RM12 “ALE 4G, 3G & 2G (48 kHz)” datasheet.

Deployment

The RM12 has a flexible and compact ½ of 1U 19-inch rack-mountable form factor and provides standard interfaces to radios (audio and control), data terminal and cryptographic equipment and management systems. The RM12 Wideband HF Data Modem and ALE connects to wideband HF radios via analogue or digital audio interfaces. The latter is based on the use of the VITA 49.2 standard.\

Companion Product

The companion product of the RM12 is the RC12 Wideband ARQ and IP Controller which provides automatic repeat request (ARQ) services based on STANAG 5066 Edition 4. In addition, the RI12 IP-to-Sync Controller product can also be considered for split-site installations.
