Test and repair cellular network equipment


Application

This unit describes the skills and knowledge required to analyse cell performance and perform diagnostic tests and repairs on sub-elements and subsystems within cellular networks.

It applies to individuals working as field officers and technicians who may be responsible under supervision for small projects or parts of larger projects and for the coordination of projects in sites remote from the organisational headquarters.

No licensing, legislative or certification requirements apply to this unit at the time of publication.


Elements and Performance Criteria

Elements

Performance Criteria

Elements describe the essential outcomes

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Prepare to test cellular network equipment

1.1 Produce alarm list from cellular network subsystem that shows faults or disturbances

1.2 Reset sub-element according to manufacturer’s specifications

1.3 Clear or block alarms and adjust alarm thresholds according to manufacturer’s specifications

2. Test cellular network sub-element equipment

2.1 Test parameters influencing cell performance and record performance for a range of field settings

2.2 Test, record and report sub-element performance according to manufacturer’s specifications

2.3 Run diagnostic test on sub-element

2.4 Swap working or executing sub-element with spare or idle unit to allow software upgrades

2.5 Swap working or executing sub-element with spare or idle sub-element to allow replacement of hardware

3. Rectify faults in cellular network equipment subsystems

3.1 Locate faulty sub-element within subsystem and identify fault

3.2 Identify faulty parts or equipment and replace or repair according to service agreement

3.3 Record fault details and rectification summary

3.4 Hand over and sign off with client

Evidence of Performance

Evidence of the ability to:

prepare the cellular network alarm system

produce an alarm list and use this to locate faults

test cellular network parameters and performance

measure output power received around a cell

run diagnostic tests on sub-elements and subsystems

locate and repair faulty sub-elements and subsystems.

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


Evidence of Knowledge

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

explain anti-static protection and its importance and potential effect on cellular network equipment

summarise cellular antenna installation procedures

outline electrical concepts and measurements required for cellular network repairs

explain electromagnetic radiation (EMR) and mitigation

list the common network components and describe their basic functions

provide an overview of:

the progression of generations of cellular networks

features and operating requirements of test equipment

outline procedures for repairs and swap activities

summarise test operation of cellular network equipment

list and describe the tests required for network components

describe the importance of voltage levels and polarity

describe the precautions and actions required to minimise, control or eliminate hazards related to cellular network equipment installations.


Assessment Conditions

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications – radio frequency networks field of work and include access to:

a site for mobile phone network tests and measurements

performance testing software

relevant legislation and documentation to test and repair network equipment.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
