I have a case that I´ve been working with for quite a long without finding a good solution.

I need a system that can transfer video wireless for about 1km a distance from camera to tablet/pc, with download speed of 5-10MB/sec. The system needs to be user friendly, mobile and able to work outside and coupe with down to -5 degrees celsius.

The case is this.

Skiing, Big Air. The skier jumps, the coach standing on the jump filming the jump (with for example a go pro Camera) The skier landing and wants to see the jump on a ipad, tablet, computer or similar directly after the jump. Instead of taking the lift to the top, go down the hill to meet up with the coach to see the previous jump. This is a time consuming and low efficient way of working when the skier has to "sacrifice" one jump just for watching the previous jump.

I´ve been thinking about Eye-fi card. Great because of it´s automatically download feature but the card I´m using (from 2013) is unable to connect to local net. and the net inside the card is to weak when it comes to distance and speed.

I´ve been looking torwards the DJI Lightbridge system which seems like a great system but it´s designed for streaming, I want to use it for automatically download. Anyone knows about lightbridge for downloading video not only streaming?

Is there any other soloution out there? I really appreciate all the help I can get.

Best wishes
Lars
