The COFDM modulation associated
to digital video compression is certainly now the best
solution for wireless video transmission. Digital compressed
video allows to maintain a constant picture quality,
this quality is not affected by the carrier to noise
ratio. Also, the Doppler effect
due to the mobility doesnt affect the picture
as it is with analogue transmissions. When there are
echoes like in urban areas, the receiver uses the multi-path
as an advantage, this make the link stronger compare
to analogue transmissions.
This technology offers many new horizons in video transmissions,
but there is nothing magic. And a numbers of rules has
to be considered before any Kind of applications.
Metracom has got expertise in this technology since
many years, and answer to any projects with a technical
and economical approach.
Mobile transmissions :
Digital wireless camera system can be installed on different
kind of vehicles. Rugged solutions are developed to
address the hard conditions of the mobility, outdoor
operations,
.
Portable systems : Directly
docked to the camera the Digital wireless solutions
can offer incredible results. The solution will have
take into account specific requirement of the application,
such as transmission latency, area to
cover with spatial diversity,
