Content is updated to align to the new CCNA Wireless exam Based on the blueprint of the updated Implementing Cisco Unified Wireless Networking Essentials (IUWNE) exam, state-of-the-art Wi-Fi technologies such as IEEE 802.1ac, spatial streams, and multi-user MIMO will be added to the exam. Cloud-based and converged wireless and network architectures will also be covered, including branch deployments.  In terms of layer 3 connectivity, both IPv4 and IPv6 wireless implementations will be included.  For centralized management, Prime Infrastructure takes on greater importance.  The exam will have a new emphasis on troubleshooting client connectivity, including specific issues with BYOD, by validating network configurations and leveraging third party troubleshooting tools. There will also be a new focus on RF design and the site survey process.
