Maybe one can just use on-board wireless device and use something like super-beam or some like program. Guess speeds have factors as modem/router, on-board wifi card capabilities and storage write speeds.
I have a couple wireless USB devices but never thought about connecting them. Can use them as servers and leave em running on cheap bleeping wall-chargers indefinately; storage depends on size of micro SD cards.
I currently use superbeam (not advertising) and I get 10+ Mbps send/receive. Comes in handy when transferring data from mobile devices and other PCs and like devices (without tethering > "killing" ports that are designed to fail with over-use ..hahahaha.. However I am using a old bleep router and and we only use our mobile ports far charging. >>> Have some wireless chargers (QI?) but I hated the heat and discarded the idea > more "kililling" >.
Other methods of transferring data but one would consider the wireless protocol or p2p (WiFi direct or other), expectations and user-friendly?... not always the case but getting better daily.
If I can do it; Anyone can.
