Elements and Performance Criteria

Monitor the capacity of the cellular mobile network
Make recommendations relating to capacity changes
Assess capacity changes
- Organise tests and studies to ensure that increased capacity adequately caters for traffic flow
- Make recommendations for further change to network should the increase capacity not meet need

Required Skills

Required skills

analytic skills to interpret capacity requirements

switching architecture and in particular space and time switching

types of adjustments that need to be made to procedures to meet the requirements of particular sites and environmental conditions

typical issues and challenges that occur in telecommunications cellular capacity design and how these may be addressed

workplace and industry environment

Evidence Required

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

source and analyse relevant data to prepare a plan indicating growth potential and recommendations for meeting growth within timeframes

use tools and software packages for forecasting and measurement

identify site or channel capacity relevant network growth and forecasting growth

Context of and specific resources for assessment

Assessment must ensure

access to sites with cellular mobile network

capacity monitoring data and equipment

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

direct observation of the candidate undertaking a practical monitoring exercise

evaluation of report prepared by the candidate outlining recommendations relating to capacity changes

oral or written questioning to assess required knowledge

Guidance information for assessment

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

ICTRFNA Test and measure cellular phone and network equipment performance

ICTRFN5148A Test and measure cellular phone and network equipment performance

ICTTENA Produce and evaluate architecture designs for convergent cellular mobile networks

ICTTEN6169A Produce and evaluate architecture designs for convergent cellular mobile networks

ICTPMGB Evaluate and use telecommunications management networks

ICTPMG8149B Evaluate and use telecommunications management networks.

Aboriginal people and other people from a nonEnglish 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
