Link Planning with Ethernet Radios for Next Generation Networks

Duration: 5 Days

Our newest and the only course available on Planning links with Ethernet Radios for HSPA, 3GPP and 4G networks:

Transmission is an important element in any mobile network, affecting the services and service quality offered as well as the cost of the mobile operator. Today, microwave access, based on point-to-point TDM microwave radios, is the dominant technology in base station access networks. However, emerging HSPA, 3GPP’s, LTE and mobile WiMax access technologies will place an unprecedented capacity and spectrum burden on microwave backhaul networks. Unfortunately, these new demands can not be addressed by current legacy TDM microwave transmissions networks and technologies making migration to next-generation packet transport a viable alternative for cellular backhaul.

ConnectionWise engineers have two years of experience in the field working on the deployment of Ethernet over microwave radios. We have developed this course to provide legacy link planners a thorough understanding of transmissions of packets over the microwave radios. This course also details the planning of links with the adaptive modulation feature and provides an understanding as to the role of OSI layers in HSDPA/LTE mobile communications backhaul networks.

Workshop Overview

The 4th generation (4G) of wireless technologies promises a much higher air interface data rate (over 100 Mbps) to users. Delivering such high data rates require a very fast and efficient backhaul network. The current T1/E1 backhaul using legacy TDM digital microwave radios cannot support such high data rates at a reasonable cost. Therefore the 4G broadband networks require all-IP and Ethernet based broadband backhaul solutions.

The course focuses on demonstrating methods for estimating the access backhaul requirements based on the type of population served, use of adaptive modulation, delay and jitter requirements. The course discusses in greater details the role of IP in cellular networks. The material also covers ATM/TDM benefits, operations and QoS support and IP/MPLS benefits.

Real world case studies are used to develop access and aggregation link plans using packet radios on third party link engineering software "Path Loss IV".

Key Benefits

The course participants will obtain a thorough understanding of the detailed knowledge of transmissions of packets over the microwave radios. This includes link planning with adaptive modulation feature, the role of OSI layers in HSDPA/LTE mobile communications backhaul networks, the step by step procedure to design end to end transmissions network using capacity requirements form set by RF and marketing groups. The participant will clearly understand how to plan links to meet 3G HSDPA end to end jitter and delay requirements.

Pre-requisite

Good knowledge of Microwave and Link Planning using legacy TDM radios and use of “Path Loss” or any link planning software tool.
