Application
This unit describes the skills and knowledge required to use network tools, equipment, software and protocols to design and integrate voice over wireless local area network (VoWLAN) services into the wireless local area network (WLAN), and to implement into the wireless network quality of service (QoS), multi-protocol label switching (MPLS), and high bandwidth applications.
It applies to individuals with excellent information communications and technology (ICT) skills who are working as wireless help desk technicians, wireless network support specialists and wireless network engineers.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

Evidence of Performance
Evidence of the ability to:
analyse and specify voice over wireless architecture requirements
design and implement voice applications over wireless local area network (WLAN)
implement a quality of service (QoS) for wireless applications
use network tools to configure and test wireless infrastructure and applications
plan and scope the wireless network bandwidth.
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 the configuration, verification and troubleshoot procedures required to undertake:
router operation and routing
virtual local area network (VLAN) switching and inter-switching communications
summarise iDevice operating system (iOS) and internet protocol (IP) networking models
outline video and high-bandwidth applications and requirements
explain voice applications and protocols
clarify voice over wireless local area network (VoWLAN) technologies
describe the following aspects of wireless networks:
current regulations, standards and certifications
deployment schemes
network security technology
network topologies and elements
networking protocols
summarise WLAN devices and their specification and use.
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 must be typical of those experienced in the networking industry, and include access to:
a site where network installation may be conducted
hardware and software
organisational guidelines
computers
stand-alone and lightweight WLAN controllers and AP
hardware and software LAN/WLAN voice technologies.
Assessors must satisfy NVR/AQTF assessor requirements.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
Skill | Performance Criteria | Description |
Reading | 1.1 | Recognises and interprets complex technical documentation to determine and confirm job requirements |
Writing | 1.2, 2.2-2.4, 3.2, 4.4, 5.1 | Develops a range of material, including design and technical specifications, for a specific audience, using clear and detailed language to convey explicit information, requirements and recommendations |
Numeracy | 5.3 | Interprets numerical data and undertakes measurements to evaluate performance and interoperability of the network |
Get the work done | 1.1-1.3, 2.1- 2.4, 3.1-3.3, 4.1-4.4, 5.1, 5.2, 5.4 | Demonstrates a sophisticated understanding of principles, concepts, language and practices associated with the digital world and uses these to troubleshoot and understand the uses and potential of new technology Uses a broad range of strategies to store, access and organise virtual information, recognising that design choices will influence what information is retrieved and how it may be interpreted and used Is acutely aware of the importance of understanding, monitoring and controlling access to digitally stored and transmitted information May operate from a broad conceptual plan, coordinating the process with others to identify functional, performance and management features associated with the operation of complex VoWLAN services Uses nuanced understanding of context to troubleshoot and debug WLAN issues, adapt configuration procedures to network requirements and reconfigure depending on differing operational contingencies, risk situations and environments |
