I'm trying to find out the wireless technology that I can use for peer to peer communication. The main requirement is to have good data transfer speed (at least 500kps or more), pairing process should be without user intervention and the devices will be in close proximity during the communication, probably <15cm.
I have evaluated UWB but it seems packet loss could be an issue there. IR is out as well due to speed and longevity. Do you think active NFC will fit into my need?
I understand that BLE and WiFi Direct could be another option but those will demand another technology for without user intervention pairing. Any thoughts are highly appreciated?
