when i think of WiFi I mostly consider it a wireless ethernet cable attaching to a network. usually the main thing on that network is internet access but at home it also includes a printer. when I think of a wireless chartplotter I think how nice it would be to connect it to a wireless depth transducer, RADAR, knotmeter, wind instruments, all those things a multi function chartplotter gets via NEMA now but without all that wire. It's all coming together.
