What is the Space of PMR/PMAR in the era of NGN?

This workshop explores the space of Private Mobile Radio (PMR) and Public Mobile Access Radio (PMAR) in the Next Generation Network (NGN) era. It discusses the need for a dedicated network to support critical incidents and interoperability among public safety responders. The workshop also highlights the TETRA standard as a reliable and secure solution for critical communications.

  1. What is the Space of PMR/PMAR in the era of NGN? ICT Workshop Brasília Nov.10, 2006

  2. NGN, FMC, IMS, 3G … • Assume all are implemented • Is there room for another kind of network? • What customer need could drive it?

  3. More and more Critical Incidents • Critical incidents impact everyone • Public pressure necessitates a move from independent operations of respondents to interdependent collaboration “No man, woman or child should lose his or her life because public safety officials cannot talk to one another.” The Public Safety Wireless Network

  4. Who are the Public Safety Responders • Police • Fire • Emergency Medical Services • Rescue • Civil Defense • Public Utilities – Electricity, Gas, Water • Essential Transport

  5. Communication Requirements of Emergency Responders • Group Calls • Operations / Dispatch Centers • “instantaneous connection”`< 0,5 s • Pre-Emptive (Emergency ) Call • Priority Levels • Encryption • Interoperability wiht Autonomy • Multiple Resilience Levels • Redundancy • Site Operation • Direct Mode

  6. Commercial Network Suitability National Task Force on Interoperability says.. “Public safety officials cannot depend on commercial systems that can be overloaded and unavailable”

  7. True Interoperability Enables instant communications among multiple responders and different agencies

  8. True Interoperability Consequences • More coordination regardless of network type or agency affiliation • Seamless access to voice and data intelligence • Coordinated response can happen in seconds, not hours or minutes “True Interoperability allows public safety personnel in different agencies to communicate with each other on demand in real time” --Public Safety Wireless Network

  9. Coverage • Designed to user needs; not profit based • Extensive planning • Additional capability beyond traditional network coverage “…I think the most salient point [of having your own system] is the ability to maintain a service level without a profit motive” Steve Jennings, CIO Harris County, TX

  10. A Critical Network Provides the availability, information security and reliability that responders require

  11. Critical Networks • Reliable • Always available • Redundant • Priority access at all times Critical Networks are the Lifeline whenever lives or outcomes depend on communications

  12. The TETRA Standard • ETSI developed standard • Digital benchmark for wireless communication networks • Currently operating in 77 countries • Supported by Schengen Group of Public Safety • Supplied by many providers (multiple subscriber and infrastructure vendors)

  13. ENCRYPTION Packet Data Data Transmission fast and reliable TELEPHONY Full Duplex TWO-WAY RADIO Group and Individual Calls, emergency calls, priority levels, DMO The TETRA Standard • Strong multi vendor support • High capacity - ideal for shared networks • Efficient use of spectrum • Longevity of investment • 20 years + • Ongoing enhancements • New applications on installed infrastructure • Data Applications • Multiple & High Levels of Security • Multiple levels of Resilience

  14. Four user channels multiplexed into one 25 kHz carrier TETRA TDMA principle • TDMA (Time Division Multiple Access) • 4 channels per 25 kHz carrier • 4 calls per 25 kHz carrier (data or voice) • Voice and Data can be transmitted simultaneously 36 kbits/s gross bit rate 2 1 4 channels 3 4 Carrier SPECTRUM EFFICIENCY

  16. Voice Services Fast call set-up Individual (one-to-one) calls Express calls (push and talk) Group communication group calls scanning of groups dynamic regrouping group area broadcast groups Emergency calls Direct mode Voice Dispatch Services Group monitoring & communication Joining groups Preemptive speech item Group member list Dynamic regrouping Broadcast group. Data Services Status service Short Data Service, SDS IP packet data Circuit mode data Services

  17. The TETRA Association • Formed in 1994 • Promote the ETSI TETRA standard world-wide • Achieve Harmonised Spectrum in Europe • 380-400MHz • 410-430MHz • 870-920MHz • Encourage an open and competitive market

  18. TETRA Association – Some Members

  19. Open and competitive markets • Fully compatible equipment • Interoperability process created • Independent test house • Certification process • Fully supported by industry

  20. The future of TETRA • Special Working Group formed • To consider future user needs • To ensure TETRA remains relevant in the coming decade • New Codecs • Air Interface enhancements • Range extension • High speed data
