Course Details
In a bid to improve both network capacity and data throughput, service providers are increasingly turning to Wi-Fi as a viable addition to their network infrastructure. This course explains how Wi-Fi offload is supported in terms of providing a seamless transition between the two radio technologies, tracking the architecture required, the mobility options available and the fundamental concepts of operation.
