Explain The Frequency Allocation Concept?

Answer»

In FDMA or TDMA, RADIO resource is allocated not to interfere among neighbor cells:−

  • Neighbor cells cannot use the same (identical) frequency band (or timeslot).
  • The LEFT figure shows the simple cell allocation with seven bands of frequency.
  • In actual situation, because of complicated radio propagation and irregular cell allocation, it is not easy to allocate frequency (or timeslot) appropriately.

CDMA system is against this, since all USERS share the same frequency, the ARRANGEMENT of the frequency is not an issue. This is in designing the system, which will be a very big advantage.
