Lightweight COFDM Digital Long Range Video Transmitter 16QAM 64QAM Modulation
LinkAV was founded in 2005 to provide wireless microwave products for video audio and data transmission based on COFDM/TDDOFDM/MESH/4G technology.
The COFDM with narrow bandwidth (2M-8MHz adjustable) and strong anti-multipath interference ability,different with analog and conventional modulation techniques, We are special for high-speed and real-time high-quality non-line-of-sight images transmission, particularly suitable for using under complex environments.
H.264 standard video coding,1080P high-definition,clear picture quality, bright colors, smooth image characteristics for high reliable video transmission.
Our wireless video transmission equipment are widely used in government surveillances,law enforcement,UAV &UGV ,broadcasting, security, civil defense, fire, emergency rescue departments,forest fire prevention, transportation, customs, railways, mining, electricity, finance and so on.
The C654 transmitter is a mini COFDM video transmitter from Wireless LinkAV, designed specifically for UAV/ Drones video transmission applications.
With proven LinkAV COFDM technology and H.264 encoder technology at its core, the C654 transmitter enables viewers high definition images ideal for establishing rugged wireless video links in all environments including mobile and urban environments.
The small size and ultra-low power consumption make the C654 transmitter ideal for UAV installations, enabling true long range HD quality transmission from these increasingly popular devices for the first time. Optional lightweight, low power consumption amplifiers are also available for even greater range capability.
