Application
This unit describes the skills and knowledge required to specify the design of Worldwide Interoperability for Microwave Access (WiMAX) network architecture.
It applies to individuals working as information and communication technologies (ICT) technicians, designing and operating WiMAX networks in wireless core and access networks. Wireless convergence technology in telecommunications particularly applies to the deployment of fast wireless broadband access.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

Evidence of Performance
Evidence of the ability to:
review and assess the Worldwide Interoperability for Microwave Access (WiMAX) communication architecture, hardware, protocols and networking systems for a new design
integrate other wireless technologies
analyse and evaluate competing wireless technologies
design viable WiMAX network solutions
assess network performance.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
outline the client business domain
explain current industry accepted network hardware and software products and their general features and capabilities
explain the design implications of the following:
current industry accepted WiMAX network protocols
remote user issues
management systems
WiMAX network design
WiMAX network traffic evaluation
explain current industry security products, devices and procedures and their general features and capabilities
outline theoretical concepts of current industry network development and design methodologies.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications – radio frequency networks field of work and include access to:
IEEE 802.16 standards for WiMAX
client requirements
technical specifications
expected traffic volume
vendors and vendor offerings and pricing
information on a range of IT business solutions
future organisational business processes
a budget for architecture designs for WiMAX networks.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
