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. Critically analyse suitability of radio systems | 1.1 Critically analyse spectral efficiency of functional elements of mobile radio systems for determining optimal frequency utilisation 1.2 Critically analyse features of radio systems to evaluate effectiveness of a particular application 1.3 Compare features and specifications of antennas used in radio systems to assist with radio link budget 1.4 Report on suitability of radio systems, including recommendations to improve network performance |
2. Calculate a radio link budget | 2.1 Calculate path loss using variables in appropriate propagation models for a power link budget 2.2 Evaluate power link budget against allowable power margin specifications 2.3 Evaluate modulation types and spectral efficiency 2.4 Confirm radio power link budget achieves specified reliability |
3. Complete evaluation and planning documentations | 3.1 Complete an evaluation report on performance of radio systems with recommendations on system improvements 3.2 Document processes used to determine optimal power link budget for a radio system |
Evidence of the ability to:
analyse signal degradation characteristics of radio paths and calculate power budgets for various distances and antenna heights versus transmitted power
research constraints imposed by mobile phone frequency allocations and simulate carrier to interference radiation patterns around a cell site
create evaluation report on radio system performance
document processes used to determine power link budget.
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 high frequency (HF), very high frequency ( VHF), ultra high frequency (UHF) and microwave receiving techniques
summarise modulation methods:
AM
FM
digital
outline multiplexing systems
summarise operation of transmitters and receivers
explain organisational policies and procedures
summarise personal safety issues
explain propagation methods
summarise radio communications systems
weigh factors affecting radio frequency (RF) path loss
summarise RF technologies.
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 industry and include access to:
a telecommunications operations site
mobile telephony devices and equipment
networked computers and relevant software.
Assessors must satisfy NVR/AQTF assessor requirements.
