[swinog] OT: network connection 500 - 1000m

Dear networkers,

I have an off-topic network problem, but some ppl here might help me. I need to build an IP network line from the middle of a construction site to an internet connection place for a one-time event. The distance is around 500 - 1000m. No line of sight and therefore directed WLAN will not work without several relays.

At the moment I'm thinking of using a copper line and some old fashioned 1MBit lease line modems. Do you have other ideas of getting this to work or may have any parts which you can lend?

The event will happen at the end of July on a single week day. Thank you for your help.

Cheerz, - Dan
