# Wireless Sensor Network Fundamental?

I am currently investing the topic: Wireless Sensor Network. Specifically, I need to show the calculation of how much power received against distance between the transmitter and receiver in WSN. However, I don't have any background to it. I am only asking help to get me started on this topic.

So, what is the basic formula of power transfer between transceivers?

This might be what you are looking for.

You can solve for Pr for the receive power or Pt for the transmit power and R is the distance.

This equation has antenna gain and frequency factored in so I'm not sure if there is a more simplified version with just power and distance.

Hope this helps you get started at least!

Link Loss (dB) = 32.45 + 20$log_{10}$(F) + 20$log_{10}$(d)
Power required in dBm is -154dBm + 10$log_{10}$(data rate) dBm
