Can we make a simple wireless device by mutual induction phenomenon
So does this mean that the basic principle behind the both is same?


It is the same basic principle but, it's sufficiently dogged in differences that in the case of mutually coupled coils, the H-field falls with distance cubed whereas with a full EM wave the H-field falls linearly with distance. That means a fundamental difference to the range one can get for a given power input. Here's the Biot-Savart law applied to a coil: -



The formula at the bottom of the picture becomes an inverse cube law when Z>>R but, you could build big coils at about 1m diameter - do you envisage this as a possibility to consider?

The reason why a full EM wave doesn't "fall" as rapidly as cube law is that the E-field produced by "small" coils is nowhere near enough the right magnitude compared to the H-field. A full-fat EM wave has E to H in the ratio 377:1. Regard it is volts per amp or resistance i.e. the resistance of free space is 377 ohms.

To get the coil to be "E" resonant means it has to have dimensions of circa one wavelength. 30 MHz has a wavelength of 10 m and 10 MHz has a wavelength of 30 m so, depending on what frequency you envisage, they may need to be quite large.
