About Sdison
From specialized research in wireless communication to a global supplier of mission-critical COFDM and MANET transmission systems.
Shenzhen Sdison Technology Co., Ltd.
Founded in 2014, Sdison Technology is a high-tech enterprise specializing in the R&D, manufacturing, and sales of wireless video and data transmission equipment. Headquartered in Shenzhen, China, we serve mission-critical applications in public safety, military defense, emergency response, unmanned systems, industrial automation, and broadcast media.
Our core competency lies in COFDM (Coded Orthogonal Frequency Division Multiplexing) and MANET (Mobile Ad-hoc Network) technologies — delivering reliable non-line-of-sight (NLOS) communication in the most demanding RF environments. From compact OEM modules to full-scale mesh network systems, every product is engineered for field reliability, low latency, and resistance to interference and interception.
With a dedicated R&D team, in-house manufacturing, and a global distribution network, Sdison provides end-to-end solutions that meet the stringent requirements of government, defense, and industrial clients worldwide.
The Technologies Behind Every Link
Our systems are built on a foundation of proven, battle-tested wireless technologies that ensure connectivity where conventional radio fails.
COFDM
Coded Orthogonal Frequency Division Multiplexing — the foundation of reliable NLOS video transmission through buildings, foliage, and terrain obstructions.
MANET Mesh
Mobile Ad-hoc Network topology — self-forming, self-healing mesh nodes that route around failures for unbreakable battlefield and emergency links.
AES-256
Military-grade 256-bit encryption safeguarding every transmission against interception, tampering, and unauthorized access.
FHSS
Frequency Hopping Spread Spectrum — 130 MHz hopping bandwidth that defeats jamming and interference in contested RF environments.
TDD-COFDM
Time-Division Duplex COFDM enabling bidirectional data and video over a single RF channel with 10–30 ms ultra-low latency.
NLOS
Non-Line-of-Sight operation — robust multipath tolerance delivering reliable links where conventional radio loses signal entirely.
How We Build
Three principles guide every decision — from schematic to support channel.
Mission-First Engineering
Every product is designed from the operator's perspective — field-rugged, simple to deploy, and reliable when it matters most. We test beyond spec to ensure performance in the harshest environments.
Open Integration
We provide SDKs, API documentation, and OEM/ODM support so integrators can embed our radios into existing C2 systems, drone platforms, and robotics architectures without proprietary lock-in.
Global Partnership
From Shenzhen to the world — we serve system integrators, government agencies, and defense contractors across 30+ countries with localized technical support and rapid logistics.
