Android device connecting technologies available for development [closed]

manpreet Best Answer 3 years ago

I have searched a lot over internet about device to device connecting technologies in other words device to device connection implementation in the concern of hardware and software.

Someone please tell me a whole list of technologies available for the connection between two specific android device, no matter what hardware specification they have in them.

I want a overview over those technology which are used to make data transfer between two devices using wireless connection, Like : Wifi, Bluetooth, etc.

This question i am asking because of client asking me about a "Acoustic sound technology". I don't know about it and neither i found something related to it.

Help will be appreciated.

EDIT Now i know that it is Ultrasonic data transfer which uses device's mic to generate a sort of sound frequency and get the data on the behalf of that frequency, i don't know exactly about that's why i asked it here.

Sorry if it difficult to understand, I am a little bad at English.
