You really do not provide enough information.
An IP station will require a wireless router with a connection to the Internet. No computer should be needed.
If you go with a USB or serial station you will need a computer 24/7 and a connection to the Internet.
And, probably some one half way knowledgeable to restart the computer should there be a power failure or some other reason for a reboot.
IP is probably the easiest way if there is no one to monitor /control the station.
And, the real question is how much money are you willing to spend?
