REPOTER Mobile wireless COFDM system
The Reporter Mobile wireless COFDM system is intended for digital video/audio transmission
in a frequency range of 2GHz from a TV van to central TV studio.The system provides reliable
transmission for up to 25km line-of-sight. Also it can transmit to at least several kilometers
non-line-of-sight (the distance depends of an environment) and provides reporting on the move.
The system is best suited for news, music festivals, sports broadcasting and can be mounted
in ground or airborne vehicles. In conjunction with the VIDEOLINK wireless system it provides
real-time reporting without wasting time on equipment deployment (mounting antennas, unrolling
cables and so on).
