A university department has a program in video processing and editing. Students in the department use Wi-Fi to interact with the video servers. The editing and processing is done by the students accessing and using the video servers. However, the students must then stream their results, via Wi-Fi to their laptops to verify the results. A network architect has determined that no more than 20 APs will be needed for the Wi-Fi solution. Because of the large amount of bandwidth used during the streaming, the Aruba mobility controller solution will need to support 10 Gbps links.
Which solution would cost-effectively meet this customer's requirements?
