Implement voice applications over secure wireless networks

Assessment tool

Version 1.0
Issue Date: April 2024


This unit applies to integrating voice over wireless local area network (VoWLAN) services into the WLAN and implementing quality of service (QoS), multi-protocol label switching (MPLS), and high bandwidth applications into the wireless network. Relevant job roles include advanced wireless help-desk technician, wireless network support specialist and wireless network engineer.

This unit describes the performance outcomes, skills and knowledge required to use network tools, equipment, software and protocols to design and use voice applications over a wireless local area network (WLAN).

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

Prerequisites

Not applicable.

Employability Skills

This unit contains employability skills.



Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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:

produce voice over wireless architecture requirements

evaluate, design and implement voice applications over WLAN

use network tools to configure and test wireless infrastructure and applications.

Context of and specific resources for assessment

Assessment must ensure access to:

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

appropriate learning and assessment support when required

modified equipment for people with special needs.

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 installing, configuring and testing a new or updated network

evaluation of documentation prepared by the candidate outlining testing procedures, test results, recommendation to network changes and completion records

verbal or written questioning of required knowledge.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate.

Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.

Indigenous people and other people from a non-English speaking background may need additional support.

In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.

Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

communication skills to liaise with internal or external personnel on technical, operational and business-related matters

literacy skills to:

interpret technical documentation

write reports as required

numeracy skills to take test measurements, interpret results and evaluate performance and interoperability of network

planning and organisational skills to:

coordinate the process in liaison with others

plan, prioritise and monitor own work

problem-solving and contingency-management skills to:

troubleshoot and debug WLAN issues

adapt configuration procedures to requirements of network

reconfigure depending on differing operational contingencies, risk situations and environments

research skills to investigate appropriate hardware to meet requirements

technical skills to:

select and configure networking devices and assess and implement security requirements

use networking tools.

Required knowledge

configuration, verification and troubleshoot procedures to undertake:

router operation and routing

VLAN switching and inter-switching communications

IOS and IP networking models

video and high bandwidth applications and requirements

voice applications and protocols

VoWLAN technologies

wireless:

current regulations, standards and certifications

deployment schemes

network security technology

network topologies and elements

networking protocols

WLAN devices and their specification and use.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Voice requirements may include:

codecs

data flow

hardware

skinny call control protocol (SCCP)

session initiation protocol (SIP)

software

standards.

Wireless requirements for voice may include:

cell overlap

cell separations

delay

jitter

latency

QoS

traffic separation.

Security may include:

802.11r

Cisco centralised key management or proactive key caching (CCKM/PKC)

extensible authentication protocol-flexible authentication via secure tunnelling (EAP-FAST)

lightweight extensible authentication protocol (LEAP)

protected extensible authentication protocol (PEAP)

wi-fi protected access with extensible authentication protocol-transport layer security (WPA or WPA2 with EAP-TLS).

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
