AT A GLANCE Rohde & Schwarz has developed a state-of-the-art generation of communications systems designed to take HF radio to the next level. HF wideband functionality (in line with MIL-STD-188-110D and STANAG 5069) speeds up HF data transmission to achieve data rates comparable to those attained with SATCOM. Shortwave communications are a resource that can be set up easily, offers extreme reliability and is highly valued by security authorities and organizations as well as military users all over the world. The R&S®M3SR Series4100 HF radios are innovative, versatile software d efined...

IP FOR EASY INTEGRATION IP is becoming generally accepted in all areas. The R&S®M3SR Series4100 offers IP support at both the air interface and the radio for receiving payload, control and audio data. R&S®IPoA IP-over-air HF wideband radio transmission The R&S®IPoA embedded radio protocol provides transparent IP functionality over the air in contiguous HF channels up to 48 kHz bandwidth. It can be used to set up communications systems that require transparent connection of IP networks over radio links. IP-based applications – such as situational awareness or message handling systems – are...

Voice over IP, SIP and phone patch Phone patch The R&S®M3SR Series4100 radio family has an IP interface as standard, which can be used for remote control, configuration and also transmission of digital voice from and to the radio. Thanks to this interface the radio can be easily integrated into systems using one cable. Although other interfaces such as audio line interface or serial RS‑232 are no longer required, they are still available. The phone patch is used to integrate the R&S®M3SR Series4100 radio into an SIP phone system. With ALE-3G or ALE-4G, participants in the radio network can...

INTEROPERABLE WAVEFORMS FOR MULTINATIONAL COOPERATION Interoperable waveforms are required to enable cooperation among different nations. The most important waveforms for multinational cooperation are covered by the NATO HF House. The R&S®M3SR Series4100 family supports these waveforms. NATO has defined several standards to ensure interoperability between modern HF transceivers. The HF House is a structured overview of different HF standards ratified by the NATO countries. The R&S®M3SR Series4100 family supports most of the waveforms mentioned in the HF House. These waveforms can easily be...

The ALE-3G xDL protocols permit ARQ-secured, channeladaptive data transmission that has been optimized for the special characteristics associated with shortwave channels. Mechanisms such as code combining and packet aggregation optimize the data throughput. Due to its robustness, the LDL protocol can even transmit reliably in channels with a negative signal-to-noise (S/N) ratio. ALE-4G (in line with MIL-STD-188-141D App. G and H) ALE-4G (fourth generation automatic link establishment) enables link establishment for HF wideband channels with a bandwidth of up to 48 kHz. The link is set up in...

SECURE AND RELIABLE COMMUNICATIONS Due to the potentially worldwide propagation of an HF signal, it would be possible to eavesdrop on communications all over the world. In order to protect confidential transmissions effectively, the information must be encrypted. Secure digital voice/data (SDV) Last ditch voice SDV provides easy-to-use, versatile embedded encryption for fixed frequency connections as well as for connections established with ALE-3G and ALE-4G. In order to ensure reliable connections in heavily disturbed channels, the radio must employ extremely robust transmission methods: A...

Management of black keys for additional security R&S®SECOM-H is a Rohde & Schwarz proprietary HF frequency hopping radiocommunications waveform similar to STANAG 4444. It is designed to operate in environments where a certain percentage of the hop set frequencies are blocked due to either intentional (i.e. jamming) or unintentional disturbances, as well as in environments with severe Doppler spread and/or multipath delay. In addition, it is based on modem waveforms that can be adapted to the specific characteristics of the HF channel and its propagation. The COMSEC/TRANSEC crypto algorithm...

UNRIVALED RADIO PARAMETERS A high frequency (HF) radio channel is a transmission medium that is characterized by time variance, low signal-to-noise (S/N) ratios, Doppler effects and multipath propagation. However, HF allows worldwide communications due to its unique propagation characteristics. To obtain usable signals, the operating frequencies and antennas as well as the radio parameters such as sensitivity, selectivity and noise suppression are essential. Collocation capability due to excellent receiver specifications Simultaneous operation of multiple radio lines on board ships is...
