BTS Simple Plan






Analysis 
  • Both base stations in a state analogous to the parallel (in fact the earth's surface is not flat) 
  • The process of transmitting signals to the BTS is elliptical, which will occur in the region mark the middle (Fresnel zone) and will be pursed at the end point 
  • The process is influenced by the high transceiver base stations, the distance between base stations, the distance to the obstacle, and noise 
  • Although perambatannya in the air, but there is loss - loss of free space (FSLdB) loss - this loss is affecting the quality of the signal 
  • In order to measure the accuracy of the position of base stations needed to track and note the pattern of barriers that exist between the BTS, there are several formulas for estimating the height of the tower base stations in accordance with the constraints 
  • BTS Antenna has a working frequency of 2.4 GHz and is now growing again 
  • Great value will affect the frequency of the physical size of a transmitter 
  • The quality of transmitting also influenced by the frequency in accordance with the following equation 
           Q = fo / B
Q    = Quality
Fo   = frequency
B    =  Bandwith

Making simple tribble and bass

If the capacitors are arranged in series with the speakers, the capacitor will act as HPF (High Pass Filter) means to pass the high frequencies, which issued a voice vote with a higher tone.
