Elements and Performance Criteria

  1. Prepare to test cellular network equipment
  2. Test cellular network sub-element equipment
  3. Rectify faults in cellular network equipment subsystems

Required Skills

Required skills

communication skills to liaise with internal and external personnel on technical requirements

literacy skills to read interpret and prepare technical documentation

numeracy skills to read and interpret measurements and report to supervisors

planning and organisational skills to plan the test in coordination with supervisors

safety awareness skills to

apply precautions and required action to minimise control or eliminate hazards that may exist during work activities

work systematically with required attention to detail without injury to self or others or damage to goods or equipment

technical skills to

install network equipment

perform fault clearance

select and use appropriate test equipment and practices to suit different network applications

recognising and interpreting alarms

Required knowledge

anti static protection

cellular antenna installation

electrical concepts and measurements

electromagnetic radiation EMR and mitigation

network components and their basic functions

occupational health and safety OHS relevant to work activity

overview knowledge of

st nd and rd generations of cellular networks

features and operating requirements of test equipment

procedures for repairs and swap activities

test operation of cellular network equipment

testing network components

voltage levels and polarity

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

measure cell performance

measure output power received at around a cell

produce an alarm list and use this to locate faults

run diagnostic tests on subelements and subsystems

locate and repair faulty subelements and subsystems

Context of and specific resources for assessment

Assessment must ensure

site for mobile phone network tests and measurements

performance testing software

relevant legislation and documentation to test and repair network 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 performing measurements and repairing faults

review of fault details rectification summary and recommendations prepared by the candidate

oral or written questioning to assess required knowledge

Guidance information for assessment

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

ICTTENA Install telecommunications network equipment

ICTTEN3056A Install telecommunications network equipment

ICTTENA Repair and replace telecommunications network hardware

ICTTEN3089A Repair and replace telecommunications network hardware.

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
