Evidence Guide

EVIDENCE GUIDE 

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Evidence of the ability to:

  • design viable GPRS (2.5G) and 3G network solutions to meet particular business needs
  • research design features of 4G cellular networks.

Context of and specific resources for assessment 

Assessment must ensure:

  • budget for designs for convergent cellular mobile networks
  • cellular mobile network structures
  • client requirements
  • expected traffic volume
  • information on a range of IT business solutions
  • technical specifications
  • vendors and vendor offerings and pricing.

Method of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • oral or written questioning to assess knowledge of current industry networks and design methodologies
  • review of report prepared by the candidate outlining evaluation process undertaken, including challenges faced and how these were addressed
  • direct observation of the candidate undertaking multiple antenna positioning
  • evaluation of network designed by the candidate in terms of performance and suitability of business needs.

Guidance information for assessment 

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

  • ICTRFN6098A Monitor the capacity of and recommend changes to the mobile cellular network.
  • ICTRFN6171A Produce and evaluate architecture designs for WiMAX networks

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.
