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.
Elements | Performance Criteria |
Elements describe the essential outcomes | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Monitor capacity of cellular mobile network | 1.1 Monitor traffic levels from network management system 1.2 Use approved enterprise plans to identify planned network growth 1.3 Obtain client forecast data from marketing 1.4 Apply identified data against capacity trigger criteria 1.5 Determine coverage and cell parameters |
2. Make recommendations relating to capacity changes | 2.1 Identify requirements for additional capacity 2.2 Recommend changes or additions to frequency parameters and submit to planning personnel 2.3 Assess capacity of transmission path, switch resources and recommend improvements, noting transmission medium 2.4 Manipulate traffic through switch parameter settings as a means of relieving traffic congestion 2.5 Determine cost of proposed changes and undertake studies of appropriate return on investment (RoI) |
3. Assess capacity changes | 3.1 Organise tests and studies to ensure that increased capacity adequately caters for traffic flow 3.2 Make recommendations for further change to network should increased capacity not meet need |
Evidence of the ability to:
source and analyse relevant data to prepare a plan indicating growth potential and recommendations for meeting growth within timeframes
use tools and software packages for forecasting and measurement
identify site or channel capacity, relevant network growth and forecasting growth.
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 blocking, non-blocking and grade of service
explain Erlang B measurements
summarise features and operating requirements of test equipment
outline field measurements for cell traffic capacity
explain the information required to:
analyse and interpret statistical data as applied to teletraffic measurement
prepare and conduct a capacity measurement
summarise legislation, codes of practice and other formal agreements that directly impact on radio communications site transmission
outline the following including:
transmission lines
transmitter and receiver architecture and their impact on radio communications traffic
outline switching architecture with specific reference to space and time switching
outline the types of adjustments that need to be made to procedures to meet the requirements of particular sites and environmental conditions
explain typical issues and challenges that occur in telecommunications cellular capacity design and how these may be addressed.
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 – radio frequency networks field of work and include access to:
sites with cellular mobile network
capacity monitoring data and equipment.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
