I wanted to be able to transmit data from a wireless module to an Arduino. It is possible that a human body could come between the wireless module and the Arduino or someone might cover up the module with their hands. So I was looking for some kind of wireless module around 100 MHz because the human body transmits these signals without interference or absorption. I have found many 433 MHz radio wave modules online but nothing around 100 MHz range.
I was wondering if there is any off the shelf component or is there a simple strategy for creating a wireless module around this frequency range on my own?
