IP Network Migration for PMR Systems

1. PMR Migration to IP Platform M/A-COM Poland

2. PMR today • Different technologies/standards/protocols • Different users with different requirements • Different territories of operation • Different bands, sub-bands and channel spacing June 2004 - M/A-COM Poland

3. PMR today • Interoperability issue in day-by-day and crisis operation • Growingup needs and requirements • Technology changes • Demand to decrees investment and operational costs June 2004 - M/A-COM Poland

4. Preferred solution Single radio standard Advantages: • Interoperability solved • Standard=Competition=Low 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 June 2004 - M/A-COM Poland

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 June 2004 - M/A-COM Poland

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) June 2004 - M/A-COM Poland

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 June 2004 - M/A-COM Poland

8. M/A-COM’s Solution Single radio standard Single networking standard All subscribers use the same system IP based network links different radio interfaces June 2004 - M/A-COM Poland

9. M/A-COM’s Solution June 2004 - M/A-COM Poland

10. 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 June 2004 - M/A-COM Poland

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 • IPbackbone for next generation cellular mobile systems June 2004 - M/A-COM Poland

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 IPnetwork (dedicated routing, priorities, compresion 80%) June 2004 - M/A-COM Poland

16. NetworkFirst • Audio retransmission between networks independent of protocols, bands, signalizations, etc. • Fast implementation of interoperability • Smooth migration to future advanced solutions • No need to replace mobiles and portables June 2004 - M/A-COM Poland

17. NF Demo in Germany June 2004 - M/A-COM Poland

18. 1 2 OpenSky • End to End IPand Voice over IP • Client/Server architecture • 2& 4 slot TDMA • Embedded Control Channel • Voice/Data/Encryption DES/AES • Cell Sites (micro-sites) • VTAC – mobil repeater/gateway June 2004 - M/A-COM Poland

19. P25IP Trunking • Digital Narrow Band (12,5kHz) Trunking • APCO25 Common Air Interface • IP Backbone • CE Certified - Narrowband Digital PMR - ECC (02)03 • Advanced trunking features • Encryption DES/AES • Migration patch for customers with analog 12,5kHz systems June 2004 - M/A-COM Poland

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 • ... June 2004 - M/A-COM Poland

21. Future considered radio interfaces • Tetra stage 2 • PMR over CDMA (384-500kb/s) • MESA >2Mb/s Mobile Broadband for Emergency and Safety Applications • PMR over 3G June 2004 - M/A-COM Poland
