A Milestone International Deployment
In July 2011, Sdison Technology's high-definition soldier wireless image transmission system was successfully deployed at a television station in Iran. This early international deployment demonstrated the viability of COFDM-based portable video links for professional broadcast production in demanding field conditions.
Soldier-Worn Video Transmission for Broadcast
The soldier wireless image transmission system — a compact, backpack-carried COFDM transmitter — enables untethered HD video capture from a camera operator in motion. For broadcast applications, this means roving reporters and camera crews can transmit 1080i/p video back to the production truck or studio without a wired connection, even from moving vehicles or difficult terrain.
Operating in the UHF band with adjustable power output, the system achieves reliable NLOS transmission through building structures and across campus-style environments typical of large broadcast facilities. The COFDM modulation ensures that multipath reflections — common in urban and indoor settings — reinforce rather than cancel the signal.
Legacy and Continued Relevance
While this 2011 deployment predates Sdison's current SDX series MANET mesh products, the core COFDM technology remains the backbone of the company's portable and manpack solutions today. Modern equivalents, such as the HBFDD-A manpack, offer higher data rates, integrated mesh networking, and AES encryption while maintaining the same form-factor portability that made the original soldier system effective for broadcast and tactical use alike.
International deployments like this one underscore the global demand for rugged, portable wireless video links in both media production and defense applications, where the ability to transmit live HD footage from any location is a mission-critical requirement.
