Overview

Today, Wi-Fi is everywhere, and the need to provide good Wi-Fi is an essential part of doing business. But “good Wi-Fi” is not just about coverage or converting your APs to 802.11ac or 802.11ax. Good Wi-Fi means that your user experience is seamless. Most of the wireless networks today are designed to support only data applications and not real-time applications. In recent years, more and more companies are deploying real-time applications, and enterprise-quality is expected.

This Real Time over Wireless LiveLessons is a unique video course that provides the knowledge and details you need to create the best real time wireless experience for your organization. With more than eight hours of video training, Real Time Over Wireless LiveLessons demonstrates the process of designing, deploying, configuring and troubleshooting Wi-Fi networks for real time application support. The videos cover the full range of topics you need to successfully deploy real time applications over Wi-Fi. This video series will help any network engineer successfully design wireless for real time applications and deploy common real time applications (Spark, Jabber, and Skype for Business) over Wi-Fi networks.

Who Should Take This Course

Anyone interested in deploying both Wi-Fi networks and real time applications. These can include network administrators, systems administrators, audio/video specialists, Wi-Fi and VoIP specialists, and operations staff.

A secondary market would be the technical decision makers tasked with evaluating the technical feasibility of deploying Cisco Jabber, MS Skype for Business, Apple FaceTime, or another real time application over their wireless network. Cisco System Engineers, partners, trainers and other networking professionals who need to ramp-up technically on QoS technologies and designs would also benefit from watching this course.

Course Requirements

The expectation is that the audience will have some foundation in wireless networking, QoS, and real time mobile applications; however, the readers will not need expert-level knowledge of these subjects to find the material useful. Each section will have a brief overview of the basic principles, and then delve deeper into the fine details of the protocols, deployment platforms, and best practices.
