DELAY ANALYSIS
CDPD SYSTEM
DELAY MECHANISM

11. BE COMPUTER SEMINAR
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

DELAY MECHANISM
 VOICE TRAFFIC HAS PRIORITY OVER DATA
TRAFFIC
 TRAFFIC BURST
 VOICE TRAFFIC POISON RATE
 VOICE TRAFFIC ACCESS ALL CHANNELS

13. BE COMPUTER SEMINAR
 AFTER TRAFFIC BURST PACKET
RETRANSMITTED
 PRIORITY TO ARRIVAL CALL
 PRIORITY TO NEW CALLS

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
