Aspects of wireless communication of sensors

Over the past 10 years there have been rapid advances in wireless technologies and an importance of a radio frequency (RF) communication system is expanding day by day due to its advantages. In the meantime, a huge number of researchers are investigating from the various aspects of a such field. Electromagnetic wave propagation in an indoor environment and penetration trough environment medium is still under consideration. In this paper, we reveal a measured result from the different indoor environments for different transmitted power levels and frequencies. The experience can use to application of wireless communication between sensors.
