There is an android app that claims to have device-device transfer speeds which are much faster than the underlying protocols allow for:

Amazing transferring speed

200 times Bluetooth speed! (Speed will be affected by the equipment & the surrounding). Thoroughly defeat BlueTooth/NFC/AirDrop. Better than all you know

I searched but can't find any discussion about this. How can this be possible?

  • Zapya is name of an app, where did you get the idea it relates to a technique? – MariusMatutiae Sep 15 '15 at 7:31
  • This question is not on topic for Super User, but you might get some answers over at android.stackexchange.com. I have removed the link to the app's Store page in case of accusations of promotion- there is a quote of the relevant claim if folks want to find it. I think the claims amount to snake oil, but I'll let someone with greater knowledge weigh in. – bertieb Sep 15 '15 at 7:56
  • Clever marketing? BT 2.0 is 3.0 Mbs max and Wireless 802.lln is 600 Mbs max. 3*200=600. – DavidPostill Sep 15 '15 at 8:02
  • @DavidPostill hah, I guess. What's the spec for BT 1.0? I have another multiplier for their marketing team... – bertieb Sep 15 '15 at 8:28
  • Not sure. BT 1.2 max is 0.7 Mbs – DavidPostill Sep 15 '15 at 8:38

Zapya uses WiFi-direct for connecting two devices. If you run to create group in Zapya it turns your WiFi off(disconnecting from internet) and turns your WiFi-Direct instead on and this coase your phone device to act as a WiFi hot spot for others. On second device when you search and join to group, it turns WiFi on and search WiFi hot spot witch matches particular naming in Zapya formula. So two devices enter in private LAN with high speed connection.

enter image description here

Some other apps, for example SHAREit ,do this like Zapya. and on most new devices you can share a file throw WiFi Direct without any application.

But if your question is about how to increase data transfer through WiFi-Direct , I think it is a secret technical algorithm and they wont publish it somewhere in web.
