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

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
