Description

The ultimate hands-on bridging experience. Learn to design, configure, and deploy long distance wireless bridge links using the Cisco 1230, 1242, 1310 and 1400 wireless bridges. In this four-day course, you will focus on the basics of WLAN bridging, topologies supported, regulations (FCC, ETSI, and FAA), calculation tools, path considerations, antenna selection and alignment, mounting considerations, NEMA enclosures, lightning protection, and towers. You will learn to perform path analysis and design bridge links using a compass, GPS, and topographic (TOPO) maps. During the CAWBL class you will install several bridge links and align antennas using the GigaWave state-of-the-art 35-foot bridging tower. With this in mind, dress comfortably.

Laptops are provided to participate in the hands-on labs. If you desire to use your own laptop, please bring a laptop computer with an available 32-bit CardBus slot and an Ethernet port as well as an internal wireless NIC, 802.11a/b/g. The laptop’s operating systems must be either MS Windows 2000 (SP4) or XP. The laptop should also have a 9-pin serial port or USB to serial adapter. IN ADDITION, you will need administrator rights to the laptop to install drivers for the wireless client used in class.
