Description
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).
Notes
Elements and Performance Criteria
1. Specify requirements for voice over wireless architecture
- 1.1 Analyse voice requirements for use over a wireless network
- 1.2 Specify wireless requirements for voice applications for design considerations
- 1.3 Verify network for voice readiness and suitability
2. Design the implementation of secure VoWLAN
- 2.1 Configure wireless client devices
- 2.2 Design and configure the WLAN for VoWLAN with security configurations
- 2.3 Design and configure infrastructure devices
- 2.4 Devise structured troubleshooting methodology for VoWLAN implementation
3. Design, implement and QoS for wireless applications
- 3.1 Plan general design considerations for wired QoS
- 3.2 Design wireless QoS deployment schemes
- 3.3 Configure WLAN equipment for QoS
4. Design, implement and test multicast over wireless environment
- 4.1 Evaluate general multicast concepts
- 4.2 Analyse the implications for multicast in 802.11
- 4.3 Configure multicast requirements for a wireless network
- 4.4 Devise structured troubleshooting methodology for multicast in a WLAN environment
5. Plan and scope the wireless network for video and high-bandwidth applications
- 5.1 Design and implement QoS for latency-sensitive applications
- 5.2 Analyse the requirement for video applications over 802.11n WLAN
- 5.3 Calculate and predict bandwidth requirements for video applications over the wireless network
- 5.4 Analyse the impact of the WLAN interconnectivity for devices on QoS for devices or the wired side
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).

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.
