PMR Migration to IP Platform

1

• PMR Migration to IP Platform

2
PMR today

• Different technologies/standards/protocols
• Different users with different requirements
• Different territories of operation
• Different bands, sub-bands and channel spacing

3
PMR today

• Interoperability issue in day-by-day and crisis
  operation
• Growing up needs and requirements
• Technology changes
• Demand to decrees investment and operational
  costs

4
Preferred solution
Single radio standard

• Advantages
• Interoperability solved
• StandardCompetitionLow prices

• But
• Long time of implementation
• All radios must be replaced
• Huge costs of new infrastructure
• Compromise coverage/capacity

All subscribers use the same system
5
Longing for standard

• TETRA, APCO25, TETRAPOL
• Different standards of radio interface
• No standard for system infrastructure
• Limited functionality (data transmission)
• Long implementation process
• Technology become stale

6
Band issue

• VHF Band conventional networks
• UHF Band
• 380-400MHz - Emergency TETRA - ERC (96)01
• 410-430MHz, 450-470MHz
• civil TETRA - ERC (96)04
• Narrowband Digital PMR - ECC (02)03
• New sub-bands for high speed data (4,9GHz)

7
Backbone of PMR system

• Backbone is 30-40 of the wide-area system total
  cost (switches, transmission, management)
• Backbone affects
• How fast system is implemented
• Cost of system operation
• System reliability
• System flexibility for expansion
• Implementation of new services

M/A-COMs Solution
Single radio standard
Single networking standard
All subscribers use the same system
IP based network links different radio interfaces

VIDA

• One IP network that is scalable and upgradeable
• Different radio interfaces which can be mixed and
  matched
• Voice, data and interoperability on a single
  network
• Interoperability with legacy and new systems
• The coverage and capacity you need

11
Why IP-Network?

• Off-the shelf equipment and software
• IP network can be used for different purposes
• Customers already poses or build Intranet
• IP protocol, data compression and signal
  transmission over IP evolving technologies
• IPv6 QoS, fixed addresses, IPsec, mobility
  support
• IP backbone for next generation cellular mobile
  systems

12
Why IP-Network?

• HR support for IP (no problem with IT
  specialists)
• Easy to install and maintain (one Ethernet cable)
• Relatively processing power grows and prices goes
  down
• Natural redundancy
• No problems with latency if correctly sized IP
  network (dedicated routing, priorities,
  compresion 80)

  systems

20
Multi-protocol radios

• Software defined air interface
• Universal equipment
• Easy implementation of wide-area network,
• Backward compatibility with analog,
• Smooth migration
• Air interfaces
• Analog WB/NB
• EDACS NB/WB
• ProVoice FDMA NB/WB
• P25 FDMA NB
• OpenSky TDMA WB
• ...

21
Future considered radio interfaces
