Training Course Outline
Course Duration:
2 Days
Training Course Description:
The ability to walk around a site and still maintain access to a
network for voice and data services is critical to modern competitive
business. Wireless mobile communications using Wi-Fi products provide
an opportunity for users to gain flexibility and for service providers
such as hotels to gain revenue by providing these high value services.
IT professionals must have the knowledge to use the right technology
solutions and to be able to recognise the capability and limitations
of solutions already installed by others. To successfully install such
systems some simple knowledge of radio principles is required. It is
important to appreciate the principles of the key modern technology
standards and understand the buzz words that surround the technology.
To be successful knowledge of Wireless Access Points, Routers, Bridges
Repeaters and Hot-Spots is important as well as knowing which to use
where and how to make them work effectively in the field.
Experience has shown in practice that although other vendors claim
that their products are "plug-and-play", without the right knowledge
the products may plug but often do not play. Modern products must work
even in environments where other wireless devices exist. This course
will provide an understanding of technology and provide attendees with
an opportunity to connect, configure and troubleshoot wireless
services hands-on. Attendees will learn the effective limits on
performance and be able to undertake site surveys to discover
effective performance ahead of installation.
Course Objectives
When you have completed this course you will be able to:
- Plan local mobile services using
Wireless technology
- Describe the difference between
the competing standards in use today
- Configure wireless devices to
provide secure services using authentication and encryption
- Survey a site for delivery of
quality mobile services
Prerequisites:
This course assumes attendees already have basic knowledge
