SDX1400 Mesh Handheld Radio

Overview

The SDX1400 is a single-soldier handheld self-organizing network (MANET) radio that packs a full mesh communication node into a compact, lightweight form factor — under 1 kg with dimensions of just 220 x 80 x 45 mm. It is designed for personnel who need reliable, on-the-move connectivity in mission-critical environments: police law enforcement, fire rescue, special operations, and emergency response. The radio powers on in seconds and automatically establishes links with other nodes, forming a centerless mesh network without any fixed infrastructure.

Built around COFDM modulation with 2T2R MIMO, the SDX1400 delivers up to 80 Mbps peak data throughput and maintains a minimum of 4 Mbps even after six hops. This makes it one of the most capable handheld radios in its class for high-bandwidth services such as live video backhaul, PTT group voice, GIS positioning, and personnel awareness. The radio can also extend its range via drone-mounted relay links, enabling two-way communication across challenging terrain.

Key Features

• Centerless mesh networking supports chain relay, star, tree, and hybrid topologies with same-frequency operation across 32+ nodes, with wired or wireless interconnection
• High-speed data throughput up to 80 Mbps at 20 MHz carrier bandwidth, supporting simultaneous HD video, voice, and data services during active movement
• Compact rugged design rated IP66 with a 2.0-inch status display, weighs under 1 kg, and uses a quick-swap rotary battery for sustained field operations
• Built-in BD+GPS positioning provides real-time location awareness, inter-node distance measurement, and full GIS integration for command and control
• AES128/256 encryption secures all traffic, with one-key full-network parameter adjustment and mobile-APP or PC-based web management

Technical Highlights

The SDX1400 employs COFDM (Coded Orthogonal Frequency Division Multiplexing) with 2T2R MIMO spatial diversity, operating in the 1400-1470 MHz band. The carrier bandwidth is adjustable from 1 to 40 MHz in 1 MHz steps, allowing the operator to trade off between range and throughput depending on mission requirements. The receiver sensitivity of -100 dBm ensures reliable links even under weak signal conditions. The mesh routing engine updates topology in real time as nodes move, reconstructing paths dynamically without interrupting active transmissions.

Applications

The SDX1400 is deployed across public security, firefighting, traffic police, civil air defense, environmental monitoring, flood control, power and railway emergency response, maritime law enforcement, customs and border patrol, forest fire prevention, and industrial robotics. It excels wherever real-time bidirectional wireless data, voice, and video must be maintained in complex environments — dense urban areas, mountainous terrain, coastal zones, and through foliage or built-up obstacles.

Why Choose This System

The SDX1400 combines the smallest MANET handheld footprint with enterprise-grade throughput and military-tested durability. Its zero-configuration auto-mesh, IP66 protection, and AES encryption mean first responders and tactical teams spend zero time on setup and full time on mission. No base station, no central controller — just power on and communicate.
