Ubiquiti Networks

The Ubiquiti Broadband Wireless Admin (UBWA) is a two-day, in-classroom training course that teaches the most important concepts in Outdoor Wireless Networking, with special emphasis on how to design, build, manage and troubleshoot WISP networks. Hands-on labs reinforce knowledge of wireless concepts and advanced wireless features.

Learning is reinforced with course materials and practical lab activities using airOS 8 and airMAX AC hardware.

Those students who complete the course and pass the exam at the end will be fully certified as a Ubiquiti Broadband Wireless Admin and receive their official certificate and t-shirt from Ubiquiti Networks.

Course Requirements

Students are required to bring a laptop with a wired ethernet port (or USB ethernet adapter) and Java installed/updated. Students should also bring their laptop power adapter, a powerboard and 2 x ethernet patch leads (short length – 1m or less is fine). Some knowledge in basic networking principles including IP sub-netting is assumed.

Please note: Students must bring their own kit. The trainer is unable to provide power boards, ethernet adapters, cables or laptops on the day.
