Part 1Why Trunking?
The basic advantage of trunking system
• Large Coverage Area• Large User capacity• Easy Operation for User• Dynamic channel allocation• User Queuing • Priority (Pre-empted Emergency Call)• High security level

Advanced Base Station Design
Prediction Parameter Base Station Antenna: 9dBiLink Direction: Up-link ( Terminal Tx)Receiving Signal Range : 90dBm
Portable Radio Parameter Antenna gain : 0 dBiAntenna height : 1.5 meterTX power : 4 W
Coverage plotted : Green
Mobile Radio Parameter Antenna gain : 3 dBiAntenna height : 2 meterTX power : 45 W
Coverage plotted : Yellow
BS RF Power:50W, 100W
Portable RF Power:50W
Portable RF Power:5W Network Size:No limit for the number of sites
Large Coverage• Coverage Prediction for an example
BDA (Bi-directional Amplifier)
for Blind Areas .
For example Tunnels, Indoor coverage.
Large Coverage• BDA covering the signal blind area
System Flexible Networking• Completely IP Based :“Why IP Technology?
IP Technology is basis for converging networks
IP Technology potentially allows for an easy and full-fledged integration in the existing IP infrastructure of the customer
IP Technology holds potential cost advantages for network operators and promotes the use of standard HW (COTS)
a. One IP/MPLS backbone network for several communication & data servicesb. Evolution from customer-specific or proprietary HW in IT environments
IP Technology has become mature in offering high quality media services by MPLS, QoS Tagging and Traffic Shaping
