ICTRFN5148A
Test and measure cellular phone and network equipment performance

This unit describes the performance outcomes, skills and knowledge required to test, measure and document the performance of cellular mobile phone and network equipment. It also involves analysing test results and recommending modifications to the network. The integration of specialised optical devices into existing networks may be required as part of an upgrade required by services and applications of Next Generation Mobile Networks (NGMN). No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.

Application

Field officers and supervisors from telecommunications carriers, service providers, contractors and other public or private organisations apply the skills and knowledge of this unit. They perform measurements during equipment upgrades or during commissioning, acceptance testing and routine maintenance on cellular network equipment.

The skills are mainly related to testing cellular sub-elements and subsystems. Field officers under supervision may be responsible for projects and for the coordination of projects in sites remote from the organisational headquarters. Technical officers also participate in design activities.

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:

plan and coordinate test activities and equipment

test cellular phone and network equipment according to test procedure

analyse test results

report and make recommendations on performance.

Context of and specific resources for assessment

Assessment must ensure:

sites on which cellular network testing may be conducted

use of test equipment currently used in industry

manufacturer's and enterprise technical documentation

relevant regulations and standards.

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 performing tests

review of test documentation and reports completed by the candidate

oral or written questioning to assess knowledge of testing procedures and required knowledge.

Guidance information for assessment

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

ICTRFN5097A Test cellular handset enhancements and international roaming agreements.

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.
