Why have such long range?

Even though the range is in excess of 1 mile Line of Sight, it is necessary to have adequate range and signal penetration to ensure the packets get back and forth.
Some products in the field today state several hundred feet of range but that is Line of Sight and those signals will go a fraction of that range in real life scenarios and will not be able to penetrate a metal fish shanty.
Ensure you are following all local regulations in terms of using this product.
