What is cellular system

In a cellular system, replaced the single high power transmitter with any numbers of low power transmitters (Base station) each signal providing coverage to only a fraction of service area (Cell). Each base station is allocated a portion of the total number of channels and the nearby base station (BS) are assigned different group of channels.

The neighboring base station is assigned a different group of channels that the interference between the base station is minimized in the cellular group.

In a Basic cellular system, replaced the single high power transmitter with any number of low power transmitters (Base station) each signal providing coverage to only a fraction of service area (Cell).


Advantages of the cellular system :
  • High capacity
  • Reduced in  process
  • Less transmission power
  • Reduced set up times
  • It reduced the interference which increases the system capacity
  • It improved the S/N ratio
  • Reduced the cluster size
  • More robust against the failure of single components
Disadvantages of the cellular system :
  • Handover is needed 
  • Good infrastructure needed
  • Frequency planning should be good
  • Increases the number of an antenna in each base station
