I have a question regarding the radio signals, is it possible to send data over a particular frequency band from android ? Without using any external module or Arduino/raspberry pi. For example sending the data over 60MHz frequency, from android and receiving the data on another android phone on same frequency band.

I am expecting a good solution to this.

  • Radios only work for the specific frequencies that the radio is designed for. Consumer Android devices only work for Bluetooth/WiFi and Cellular frequencies as the functionality provided by those frequencies is what sells/allowed by governmental frequency allocations. Anything else will need custom software and custom hardware for support. – Morrison Chang Dec 29 '22 at 06:25
  • Ohh, so that basically means that even if I try to develop a software, the phone will not have the function to send transmit the data ? It will need the external hardware ? – Meet Miyani Dec 29 '22 at 09:52
