Antenna functions like Ear

    There are measurements for all. There is "litter" to measure the volume of water. There is "temperature" for the measurement of heat. There is "decibel" that measures the loundness of sounds.
How about the measurement of WIRELESS FREQUENCIES?

     Have you seen an antenna before? its a metal that we use to receive frequencies from any device that transmit signals. This antennas can actually function like your ear.
    Why? because the intensity of frequency(antenna) or sound(ear) that it can receive will vary depending on the factors that may affect the measurement.
   
      If decibel is the measurement of sound that you can hear, then we have this R.S.S.I. (Received signal strength indication) for the measurement of transmitted frequency. Both functions THE SAME, their strength or loudness depends on how far the sound or the transmitter came from before it can be receive by the receiver. The farther the transmitter the weaker the receiver can receive the strenght of frequency.

    But they also have an OPPOSITE side!. They are opposing each other when converting their strength into number.
