Which of the following regarding cellular system. with small cells are correct? 1. Higher capacity and robustness 2. Needle transmission power and have to deal with local interference only 3. Frequency planning and infrastructure needed 4. That requires both circuit switching and packet switching Select the correct answer using the code given below.  Correct Answer 1, 2 and 3

Smaller cells are used where population density is huge (i.e. metro cities) hence cellular system is decentralized and robust.

  • Since the signal has to cover very little distance, the radiated power is also less.
  • But it requires proper frequency planning but the adjacent channel and co-channel interference are constant because Q/R is constant. So we have to deal with local interference only
