I am not really sure if this is the right place to ask this question.
I have an assignment in which it gives the following scenario.
There're 2 buildings A and B. The distance between building A and B is 800 meters.
The tricky part of this question is that between building A and B where they're separated, there's a natural obstacle such as river/lake.
I have did some research and I found out the following.
- Use antenna and radio receiver (w/wo signal booster)
- Use sky cabling.
Is there any other ways or devices that need to be used or applied?
