The Singapore Armed Forces (SAF) has operationalised its improved Army Battlefield Internet (ABI) system, which has been enhanced by the introduction of its new vehicle-mounted software defined radios (SDR), at a ceremony in Stagmont Camp on 4 March.
While the Ministry of Defence (MINDEF) and SAF officials would only comment that the SDR was developed from a commercial off-the-shelf product that the army and the Defence Science and Technology Agency (DSTA) - the country's principal defence procurement organisation - customised to meet the SAF's operational requirements, IHS Jane's understands that the radio is based on the FlexNet family of tactical SDR systems jointly developed by Rockwell Collins and Thales.
One of the key features of the FlexNet system is its proprietary high data-rate ad hoc networking FlexNet waveform, which is capable of achieving a maximum claimed throughput of 6 Mbps as well as the ability to support simultaneous voice, data, and video communications within a full internet protocol (IP)-based architecture for more than 150 mobile participants.
Thales also states that FlexNet is capable of supporting legacy PR4G and PR4G-F@stnet waveforms, which are still in use by 42 countries, internationally standardised waveforms such as MIL-STD, STANAG, as well as country-specific waveforms such as Panther and SEM 93. This feature ensures waveform portability and full interoperability with existing IP-based networks and applications.
The service appears to have acquired the single-channel FlexNet-One model, which has the same form factor as the PR4G VHF radio and measures 137 mm tall, 284 mm wide, and 337 mm long. The 50W VHF/UHF system operates in the frequency range of 30 to 512 MHz with a data rate of up to 64 kbps in VHF mode and up to 6 Mbps in UHF mode. However, official MINDEF specifications state an in-service data rate performance of 21.6 kbps in VHF mode.
