Wireless Network Cellular Backhaul

Summary

With rising demand for mobile broadband services, network operators are seeing sharp increases in bandwidth requirements. The cellular network infrastructure must evolve to support newer technologies that require more and more bandwidth. Mobile service providers need to gain real-time, insight into their network performance in order to manage existing architectures and ensure a higher quality of service regardless of the underlying technology.

Cellular networks may face challenges that include:

• Quality of Services(QoS)
• Testing multiple technologies - Ethernet, SONET
• SLA's
• Tracking and validation
• Network monitoring
• Cost of Network Expansion

Course Type

Brief Course Synopsis

1. Lecture Topics Include:
   • History of mobile services and the need for mobile backhaul

   • Review of the primary Transport services (DsN Ethernet)
   • Overview of the Time Division Multiplexing (TDM), DsN and Sonet
   • Sonet and DsN Frame structure, testing requirements (Bert, RTD, Service Disruption, network monitoring, etc)
   • Ehternet 802.3 basics (Frame structure, flow control, ARP VLANS, etc)
   • Testing Standards RFC2544 and ITU-T Y.1564. (Packet jitter, sequence testing, latency, throughput, frame loss, etc)
   • Testing for SLA's
   • Fiber optic Basics
