About this class

By the end of 2004, most corporate IT networks will incorporate wireless devices using IEEE 802.11 wireless LAN technologies (Wi-Fi). It is therefore now essential that data network consultants, planners, designers, and support staff to have in-depth skills and experience in 802.11 wireless networks.

This latest-edition Planet3-Certified course from this particular provider - the UKs leading company for training in wireless technologies - provides probably the most comprehensive hands-on practical coverage of IEEE 802.11 WLAN technologies available, in a 5-day fast-track format.

The course incorporates some 40 hours of training, comprising 30 lecture modules, and more than twelve hands-on practical labs, working with enterprise-grade equipment from a range of vendors.

The course provides expert guidance on Wireless LAN site survey, product selection, equipment installation, wireless network configuration, support, wireless LAN security and troubleshooting.

Who will the lesson benefit?

• IT professionals and network engineers responsible for installing or supporting 802.11 Wireless networks.
• IT professionals wanting to progress into the wireless network industry.
• Network planners, designers and support staff.
• IT Security staff, managers and auditors.

What delegates will learn

On completing this course, you will be able to:

• Understand and apply the essential concepts of Radio Frequency (RF) technology, including RF planning, RF-related calculations and spread spectrum technologies.
• Understand the fundamental operation of wireless LANs, for effective WLAN problem analysis and troubleshooting.
• Describe the rules governing wireless LANs, to comply with local radio regulations for setup and maintenance of WLANs.
• Correctly install, configure and support wireless NICs, access points, wireless bridges, workgroup bridges, wireless gateways and WLAN antennas from Cisco Systems, Proxim Inc, Orinoco, Colubris Networks and more.
• Analyse and troubleshoot WLAN problems in-depth, including RF coverage, multipath, hidden nodes and interference problems
• Work with sophisticated WLAN diagnostic tools such as AirMagnet and WildPackets AiroPeek NX.
• Perform a site survey for the installation of WLANs.
• Understand the insecurities in IEEE 802.11 WLANs.
• Identify the attacks that can occur from network hackers.
• Secure the transmission of data over a wireless LAN using WEP and Wi-Fi Protected Access (WPA).
• Secure wireless LANs using Cisco LEAP, TKIP and MIC.
• Secure wireless LANs using generic 802.1x/EAP on access points from a range of manufacturers.
• Secure wireless LANs using VPN tunelling and encryption techniques including PPTP and IPSec.
• Conduct essential security surveys to assess the presence and vulnerabilities of WLANs.

What prerequisites are required

Prior to joining the course, students should have a good understanding of Ethernet LANs and their operation, TCP/IP protocols, IP addressing and practical experience configuring and supporting Microsoft Windows 2000 or Windows XP. We recommend that delegates have a knowledge of networking as exhibited in the Net+, CCNA, CNA, or MCP qualifications.
