I was watching the tour de france the last week ,in which i encountered an interesting point. In a tunnel near paris the transmission of the tv signaL was stoped from the biker.but just, the transmission was at the start of the tunnel and at the end of the tunnel. there was no coverage inside the tunnel. as the transmission was only a line of sight transmission (through the satelite). hence it could not be transmitted.how can this limitation be solved .should we use a infrared signal for the transmission of the video signal inside the tunnel. if any of you had more information on this topic please do respond.
