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.
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Document current network configuration | 1.1 Obtain details of current network layout and parameters 1.2 Hold consultations with key stakeholders 1.3 Document the current network configuration, network topology and links to carrier |
2. Research client needs | 2.1 Identify the client's current needs 2.2 Determine future needs 2.3 Document current and future needs according to organisational requirements |
3. Implement site survey | 3.1 Select the appropriate diagnostic tools and measurement processes 3.2 Select test equipment and ensure calibration 3.3 Undertake site survey with minimum disruption to client and ensure safe working environment for users and survey personnel 3.4 Record physical infrastructure, building use, aesthetics and other issues that will impact on future network performance and acceptance by the client 3.5 Record radio frequency interference issues, sources and possible resolution 3.6 Document results of site survey |
4. Develop specifications for upgrade of wireless network | 4.1 Document the current network performance equipment and capacity for the expanded network 4.2 Assess interference issues relating to existing radio frequency, topographic barriers, climate, obstacles, transmission distances and construction materials 4.3 Assess optimum location and position of access points, repeaters, routers and other equipment 4.4 Develop cabling plans and repeater links, including power requirements 4.5 Determine frequency to be used based on client and user requirements |
5. Model network | 5.1 Determine appropriate test and modelling routines 5.2 Determine estimated network traffic and planned growth 5.3 Test planned network using modelling tools and techniques 5.4 Document outcome of tests and revise design where required |
6. Determine components for network | 6.1 Select and test vendor products and equipment where appropriate 6.2 Consult others, including emerging industry bodies, for sustainable compatibility, economic running costs and user connectivity access 6.3 Finalise components list for suitability and vendor claims 6.4 Prepare implementation plans |
7. Present design to client | 7.1 Present the design in a clear and logical fashion 7.2 Provide advice to client on reasons for design choice 7.3 Inform the client of design limitations, performance expectations and possible unanticipated outcomes, including security threats 7.4 Obtain feedback from client 7.5 Undertake modifications to design if required 7.6 Complete final design documentation and seek client endorsement |
Evidence of the ability to:
assess wireless network performance requirements for the client
measure and diagnose wireless working environment
produce wireless models and network specifications appropriate to client requirements
produce wireless network designs and component lists
document the design and obtain client approval.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
