This 3 day program covers in detail the planning processes required to plan and dimension radio microwave links for mobile broadband networks such as HSPA and LTE. After an introduction to the planning process, physical and layer 2 options, a review of base station performances is covered, detailing the expected data rates from 3G/4G base station nodes. Link planning considerations such as determining path profiles, the use of repeaters, requirements for radio surveys and the use of available radio spectrum is discussed, along with issues surrounding reliability, redundancy, planning considerations for reliable links and the causes for link unreliability.  In addition, the course covers propagation characteristics of the radio link, including power budgets and determining link margins due to atmospheric and other radio link anomalies such as Rain Fade.

Throughout the course the theory is supported with in-class exercises, and calculations; and where relevant, practical scenarios are used to reinforce the major topics.  Delegates will also be required to complete a comprehensive case study covering all aspects of the backhaul planning process discussed during the course. The exercise is assessed – with successful completion leading to certification.

Why you should attend this course?

At the end of this programme you will be able to:

• Understand the basic requirements of link planning for modern mobile broadband systems
• Draw typical architectures for backhaul systems
• Discuss the advantages and disadvantages of various layer 2 solutions
• List the performance expectations of HSPA and LTE base stations
• List where problems may occur on radio links and discuss the methods for providing reliability and redundancy
• Discuss the various options and performance figures for equipment used in broadband wireless backhaul networks
• Perform radio link budgets including link margins using appropriate propagation models
• Discuss antenna selection and show how antennas can affect the performance of radio links
• Make appropriate channel selections based on dimensioning requirements
• Explain how higher order modulation affects system performance and calculate link performance based on modulation scheme and radio channel bandwidth
