Key requirements in identifying the right technology for public safety metro scale networks
Key Requirements In Identifying The Right Technology for Public Safety Metro-scale Networks

  • Mobility

    • Do NOT assume that mobility is enabled

    • Will voice calls & VPN seamlessly hand-off between WiFi APs

  • Broadband

    • Do NOT settle for “wireless dial-up”

    • Deliver true broadband today and plan to scale

  • Multi-service

    • It’s NOT just about WiFi!

    • What about 4.9GHz Public Safety? What about WiMAX?

  • Mesh

    • Proven mesh backhaul – capacity on demand

    • Reliable, low latency, support for high quality video/voice

All Meshes Are Not Created Equal - Shared Mesh Public Safety Metro-scale Networks

Wireless Access & Backhaul

“Shared Mesh”

Multipoint-to-Multipoint Links

All radio nodes and all devices communicate on the same frequency and same channel in a hub-like broadcast fashion.

  • What Does a Shared Mesh Deliver:

  • Limited capacity – shared bandwidth

  • High, unpredictable latency, jitter

  • Very limited scaleability

  • Highly unpredictable performance

  • No ability to support Video or VoIP

Wire Ethernet Access
