E-COFDM-TX-MINI
The E-COFDM-TX-MINI and E-COFDM-TX-MAXI are units designed for the secure wireless transmission of
video and audio signals. They are suitable for non-line-of-site or line-of-site wireless applications.
COFDM MULTI-PATH TRANSMISSION
Our COFDM wireless products provide wireless transmission of video signals in areas of operation
previously thought impossible. They also provide continous 25fps video signals without video break-up. These
products are based on COFDM wireless technology which is a multi-path RF discipline where the signal is split
into two thousand wireless carriers. With normal analog wireless transmission one relies on a single carrier
(hence the picture break-up normally associated with analog wireless technology).
The benefit of this multi-path technology is that it means the video and audio can be transmitted from body-
worn links, mobile vehicle platforms and fixed installations which have barriers in between
transmission and reception.
BANDWIDTH
The E-COFDM-TX-MINI provides excellent distance and performance through its range of transmission
bandwidths, and it has increased spectral efficiency in the 2 MHz and 1 MHz narrow bandwidth modes. This is
the narrowest bandwidth available in any comparable product. The use of 4 MHz or 8 MHz
modulation at shorter distances gives broadcast-quality image definition.
CONTROLS & CONFIGURATION
Designed for extremely simple and rugged operation & control, the E-COFDM-TX-MINI has a 16-way rotary
switch for selecting between channels and different bandwidth settings. A Red LED confirms if the unit has
link communication with the receiver unit. We have two models of receivers a one channel and a four channel.
The four channel receiver is available as a 19” rack mount model or a unit suitable for mounting in an outdoor
enclosure.
