Implement voice applications over secure wireless networks

Assessment tool

Version 1.0
Issue Date: March 2024


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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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.

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.

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.
