CDPD SYSTEM
 CIRCUIT SWITCHED N/W - MANY DELAYS
 PACKET SWITCHED NETWORK
 UTILIZATION OF EXISTING NETWORK
 SPLITS THE MESSAGE IN TO PACKETS
 CONNECTIONLESS
 SENDS EACH PACKET INTERMITTENTLY

CONCLUSION
 CDPD CAN STAND ALONE BUT WHILE IT
OVERLAID ON CELLULAR SYSTEM
 INCREASES EFFECTIVE CAPACITY OF
CELLULAR SYSTEM
 DELAY -THROUGHPUT CHARACTERISTIC

16.  UTILIZATION OF CDPD IN FUTURE MOBILE
HANDSET WITH VOICE AND DATA TRANSFER
 CS-CDPD SYSTEM AND ADDRESS USER CDPD
APPLICATION BUT UNECONOMICAL
