Question
State the concept of mobile telephony and explain its working.
✓

Answer

Concept of mobile telephony is to divide the service area into a suitable number of cells centred on an office MTSO (Mobile Telephone Switching Office)/Mobile telephony means that you can talk to any person from anywhere.
Explanation: 
  1. Entire service area is divided into smaller parts called cells.
  2. Each cell has a base station to receive and send signals to mobiles.
  3. Each base station is linked to MTSO. MTSO co-ordinates between base station and TCO (Telephone Control Office).
