Learning Outcomes

Details of Learning Activities

In this unit you will learn industry recognized skills in designing, implementing and managing Wireless Local Area Network (WLAN). The learning unit will emphasis on WLAN, WMAN & WWAN.

Classroom activities:
Lectures: to introduce the important concepts.
• Attending lectures will make it much easier for you to understand the central concepts of the course
• You will feel more comfortable and you will learn more if you read the relevant material before you attend the lectures

Tutorials: to enable you to ask questions and to clarify unresolved issues
• Review the material and prepare your questions before you come to class.
• There will be an overview of course content with a focus on the material students find difficult
• If something is unclear or if you find yourself falling behind please ask for help immediately
• You may be given worksheets to complete during the tutorial

Practical exercises: to give you the hands on experience of implementing and troubleshooting networks
• In general there will be one practical exercise per week
• You will perform the exercise and write it up in a lab journal.
The lab journal will be a bound exercise book
o Loose leaf binders will not be accepted
The write up will be a record of your actions as they are performed and your corresponding observations
The write up must be performed in the lab as you perform the practical exercise, not at a later date
o Write ups not in the lab journal will not be marked
o Write ups which are not done concurrently with the performance of the practical exercise will not be marked
In general the detail of the write up must be sufficient for you to be able to comfortably perform the practical exercise a year or more later directly from the lab journal
Any difficult or tricky points should be especially noted in the lab journal for future reference
Responses to worksheets for practical exercises must be written up in the lab journal
The neatness, completeness and the presentation of the lab journal must be of a quality such that you would be prepared to show it to a future employer as an example of your work.

Work simulated activities: you will progressively implement a networking scenario as you would be expected to do in industry.
• You will be expected to work on a networking scenario progressively as you learn the material required for you to be able to do so.
• Leaving the work to a late stage and then rushing to complete it is bad industrial practice. It will be strongly discouraged and marked down heavily. You will be expected to meet progressive milestones in the completion of this activity.

Occupational Health and Safety:
• Conduct in lecture theatres, classrooms and laboratories will be of a standard required by OH&S legislation as applied to industry.
• You must behave in such a way as not to place the health and safety of yourself or anyone else at risk
• Covered shoes must be worn in all labs
• Thongs and sandals must not be worn in any lab

Preparation for the Work place:
All skills and knowledge in this course are oriented towards current industry practices and technologies. An essential industry expectation is that you are responsible for your behaviour and actions. When you are in employment you will be expected to attend work on time on a regular basis, perform you work on time to an accepted standard and be responsible for what you do. Industry will expect you to comprehend and follow both verbal and written instructions. All industry expectations will be applied to you in this course.
You will be expected to:
• Observe all Occupational Health and Safety requirements
• You must behave in such a way as not to place the health and safety of yourself or anyone else at risk
• Prepare for classes
• Attend all classes regularly and on time
• Use your class time in a productive and responsible way
• Finish your work on time to an accepted standard
• Pay attention to, comprehend and follow both verbal and written instructions.
• It is your personal responsibility to be aware of course requirements and timelines
• Please ask if something is not clear

The Preparation for the Workplace component will be an essential part of the assessment for this course. It will be included in the assessment of the practical and work simulated activities.

Activities Outside of Class:
It is expected that students allocate at least 60% of course hours for reading, independent study, project research, design, implementation, testing and problem solving activities.
