Release 

Comments 

Release 1

This version first released with ICT Information and Communications Technology Training Package Version 1.0.

Performance Evidence

Evidence of the ability to:

  • assess wireless network performance requirements for the client
  • measure and diagnose wireless working environment
  • produce wireless models and network specifications appropriate to client requirements
  • produce wireless network designs and component lists
  • document the design and obtain client approval.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

Knowledge Evidence

To complete the unit requirements safely and effectively, the individual must:

  • identify and describe wireless network survey techniques, including:
  • audit and intrusion detection systems
  • auditing and penetration testing techniques
  • bandwidth and quality of service
  • factors affecting signal quality
  • outline the key technical considerations for designing a wireless network, including:
  • features of antenna design
  • layer 2 and layer 3 design issues
  • impact of radio frequency
  • problems associated with topography and obstacles in radio transmission path
  • wireless topologies
  • wireless local area networks (WLAN) and wireless metropolitan access network (WMAN) solutions
  • outline the key client organisation considerations when designing a wireless network, including:
  • small office home office (SOHO) and enterprise local area networks (LANs)
  • transmission control protocols or internet protocols (TCP/IP) and applications
  • wireless security strategies
  • security threats
  • outline the software consideration when designing a wireless network, including:
  • network protocols and operating systems
  • security protocols, standards and data encryption.

Assessment Conditions
