Description
Employability Skills
Learning Outcomes and Application This unit describes the skills and knowledge required for a new installation project, an upgrade of capacity or technology in an existing network or as a result of convergence to next generation networks (NGN). It applies to individuals working as supervisors and engineers, who plan, design and implement satellite communications systems.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

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:

a site on which satellite analysis may be conducted

data, calculators and appropriate software tools.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
