P4700 - NATO Band IV Tactical Radios

Overview

Band IV Tactical Radios

P4700 are airborne-qualified IP data links operating in the NATO Band IV (4400-5000 MHz) that provide a compact, robust, and affordable solution for tactical communications in electronic warfare (EW) environments.

Combined with COFDM or Direct Sequence Spread Spectrum (DSSS) waveforms, the Transmission Security (TRANSEC) option enables Frequency Hopping Spread Spectrum (FHSS), adding low probability of interception (LPI) and detection (LPD) capabilities.

P4700 radios implement unique frequency offset compensation algorithms that keep communication performance at hypersonic speeds.

TDMA multiplexing allow point-to-point, point-to-multipoint, and mesh networks (MANET) with configurable time slots and dynamic routing. Any network topology can be deployed without the need for external infrastructure.

Multiple devices can be connected simultaneously to the Ethernet and serial interfaces, centralising data links for C2, telemetry, audio, and video in a single device.
