Introduction:

This course is targeted at students who are planning a WiMAX network, and who need the skills to design a network, balancing the requirements of service quality (including coverage and performance) with minimum capital and operations cost. The course teaches all Radio-Frequency (RF) design steps that an RF engineer would consider for a WiMAX deployment. Each RF design task is illustrated with practical examples, hands-on exercises and application of a software RF-design tool. This is one of three courses in a series which prepare students to take the WiMAX Network Designer™ certification exam.

Audience:

This course is designed for students who are working on RF Design for WiMAX networks.

Customize it

This 2-day course will be customized to your needs and specifications. Eno.com will assist you in identifying those needs and specifications. A word to the wise, there are many vendors of wireless training. They will typically have a broad and general course, one size fits all, already developed and just put your organization’s name on the title slide. This minimizes their effort and time investment. At Eno.com, every course is made to your exact and exacting specifications. We help you ensure what you are getting is what you really need even if at the beginning you weren’t too sure of what that was. We fit the class to your needs. We never fit you into our “standard”, one size fits all, class.

Course Objectives:

Upon completion of this course, the students should be able to: • List ten design variables that characterize WiMAX networks • Demonstrate the impacts of frequency, and various design objectives (fixed with indoor or outdoor CPE, mobile, etc.) on network design • Employ propagation modeling tools and various databases • Recommend the number of base station locations and spectrum required to serve cities of varying size, subscriber density, clutter and topography • Recommend equipment types based on manufacturer specifications • Select optimum cell sites based on coverage, demographics, local issues, and cost issues • Determine priorities for optimum design: throughput, coverage, operating cost, etc. • Identify possible interference types and sources based on deployment spectrum • Design RF links for subscribers based on throughput and coverage priorities • Anticipate evolution to a mobile

Course Outline

Module 1: The Many Faces of WiMAX At the end of this module you should be able to: • Compare the different architectures of WiMAX networks point-to-point and point-to-multipoint and mobile, as well as the 10-60 GHz vs. 2-10 GHz standards • Describe why the WiMAX standard has so many alternate options for vendors and operators • List ten variables that distinguish one WiMAX operator network from another • Describe the likely future evolution of WiMAX services • Compare and contrast product options for base stations, subscriber stations, and antennas Module 2: Overview of Network Architecture and Modeling At the end of this module you should be able to: • Explain and follow each step of DoceoTech’s WiMAX Planning checklist • Describe the types of modulation used in WiMAX standards, and the characteristics and limitations of each • Compare and contrast the design implications of point-to­point and point-to-multipoint service • Compare and contrast Line of Sight (LOS) Non LOS (NLOS) systems • Diagram the selected frequency-reuse and sectorization plans • Plan for network backhaul requirements Module 3: WiMAX Performance and Coverage Considerations At the end of this lesson you should be able to: • Relate channel options, modulation options, and noise levels to throughput • Describe the impact of regulations on network design • Determine site selection criteria • Determine cell density required for a desired level of service, performance, and coverage. • Consider the impact of noise and interference on performance • Compare and contrast uplink and downlink performance • Choose backhaul options to support throughput requirements • Understand the design impacts of a planned migration to mobile WiMAX service Module 4: Coverage and Performance Planning with modeling tools At the end of this lesson you should be able to: • Employ a modeling tool to prepare an RF plan for your network • Understand the effect of frequency, power, terrain, clutter and CPE location on coverage • Configure a modeling tool for a specific environment • Import terrain and clutter databases • Determine service level for business subscribers • Anticipate throughput for residential subscribers • Identify the type, grade and quality of service expected by the target customers • Use a capacity planning tool to estimate equipment requirements • Optimize the network based on test data • List options for accommodating system and subscriber growth Module 5: Network Design Case Study
