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. Research wireless mesh networks and formulate the system architecture | 1.1 Confirm, with regulatory spectrum management authority, the specific regulations regarding radio characteristics 1.2 Contact customer to determine wireless mesh network design specifications 1.3 Evaluate the use of frequency bands for operation of the wireless mesh networks (WMN) 1.4 Evaluate and select wireless technology, internet protocol (IP) version and mesh routing protocol to satisfy design criteria 1.5 Specify and source hardware and software requirements |
2. Prepare a detailed plan for the mesh network | 2.1 Evaluate the maximum line of sight distances achievable between backbone nodes and between mesh nodes 2.2 Plan sites where mesh nodes will be located and plot to scale on a map 2.3 Estimate quantity and length of the links required between mesh nodes to ensure design is within specifications 2.4 Design backbone links in mesh topology for scalability of future deployments 2.5 Select location of the internet gateway for the network 2.6 Allocate operating frequencies at mesh nodes, backbone nodes and wireless access points for optimum network performance with minimal interference from adjacent network routers |
3. Plan IP addresses and subnet mask | 3.1 Produce an addressing scheme and allocate IP addresses and subnet mask to mesh nodes, backbone nodes and access points 3.2 Produce a configuration scheme to secure network |
4. Document the mesh network | 4.1 Document plans and drawings for the mesh network 4.2 Produce an installation plan for building the mesh network 4.3 Following installation, configuration and testing of the mesh network, incorporate 'as built' amendments, if appropriate |
Evidence of ability to:
evaluate and select wireless technology and mesh routing protocol
plan a wireless mesh network from a project brief
produce an internet protocol (IP) addressing scheme
prepare an installation plan.
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:
evaluate antenna gain and polarisation
outline cable loss
conduct calculations for effective isotropic radiated power (EIRP)
calculate line of site radio range
explain decibels and related units
summarise IP addressing and subnet masks
explain network security and firewalls
outline a range of network topologies
summarise radio frequency (RF) bands
explain routing protocols
clarify transmission control protocol (TCP)-IP protocols
explain wireless networking hardware, access points, wireless routers and gateway
explain wireless protocols.
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications networks engineering field of work and include access to:
sites where planning a wireless mesh network may be conducted
design criteria and other site-related documentation
equipment specifications and technical documentation.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
