i dont now what is wi-fi. i see some circuit board that make wireless connection between two phone that have distance 50km. i want to build this circuit board for LAN cable.
wi-fi is a wireless networking standard for computers, officially know as 802.11, occasionally known as wifi, airport etc.
with an omni directional aerial it has a range of 150 feet, but with a tight beam directional one there have been ranges of 50km and above reported, but you would need to have a clear line of sight to get that kind of range.
wouldn't it be easier to use the internet to transfer files and stuff?
