WLAN Secure Implementation - 1 Day

Course Purpose:
This course is designed for technical personnel who need a hands on training on effectively and securely setting up and operating a Wireless LAN. Some hardware and software configuration will be a part of the course. It is not a programming or hardware building intensive course.
Case Study: This course will spend at least 50 % building and constructing a WLAN network.
Key Challenges this course will address: Establishing a WLAN infrastructure can be an efficient and productive step for many firms. In most instances a wireless infrastructure is cost effective costing less than a wired infrastructure. Nevertheless a Wireless system poses its own unique problems, namely; reliable throughput, hardware choices, a certain variety of software application development and security. The system layout and design, the products, the type of software and the type of information transfer and volume are critical and must be done properly up front
