COFDM technology used for wireless video transmission advantages
1、
For urban areas, suburban areas, buildings, and other non-depending on the environment and stop the application, has demonstrated the "diffraction" "penetration" capacity
Traditional microwave equipment, depending on the conditions in (both transceivers to be no barrier between the two) link can be established, the use of the environmental constraints, environmental inspection ahead of the need to develop measured transceiver points.
Even if they succeed, "Points", directional antenna, cable layout work is quite tedious, not only restricted access to audio source, transmission and system reliability, efficiency has been damaged.
COFDM wireless video transmission equipment, the situation has completely changed. Because of their multi-carrier technology features, COFDM equipment for a "non-line-of-sight", "diffraction" transmission advantages in urban areas, mountains, buildings and not outside-and stop depending on the environment,
The equipment will be able to achieve a high probability of stable transmission of images from environmental impact or environmental impact small.
Its two ends of the general transceiver to the antenna whole, not advance "touch", "targeted", as laid complicated audio input and output cables, depending on the audio source acquisition side, the receiver can command at the scene and / activities director for freedom.
System is simple, reliable and flexible application.
2、
Suitable for high-speed mobile transmission can be used in vehicles, ships, helicopter / UAV platforms and so on.
For most industries, the general application of wireless image model is: audio acquisition front - access points (cars, boats, aircraft) - Video and Audio Processing Center (generally through cable or satellite communication link).
Therefore, vehicles, ships, helicopter / UAV system and platform is a very important component of its core functions is one of the front-end access to real-time images.
