Question

You are designing a WLAN for a classroom in a high school. Teacher and students will take advantage of the WLAN for various educational activities, including multimedia interactive learning. The maximum data rate for multimedia traffic is around 5 Mbps. Faculties and students will use it for browsing information, email, VolP, instant messaging, and cloud-based word processing (e.g. Office 365). The RF signal from an AP can cover the whole rom. The class has 30 student users, one or two faculty users. What type of AC do you select in your design, how many AC do you think you need? How to you provide QoS for faculties vs students? How to you guarantee realtime

Answer 1

It is suggested to use 802.11ac which has capability of controlling traffic around 35 people and more advanced.

Probably 3 AC are required, as the throughput of AC is 33%, in order to get maximum throughput to all devices 3 AC are suggested.

802.11ac wave 2 protocol takes the advantage of multiple input / multiple output. It means the wireless access point can send multiple frames to multiple clients using the same frequencies. To make this possible it uses multiple antenna arrays built in to an 802.11ac.

The real time application is served better by the use of 802.11ac. Because it offers 3*speed of 802.11n, well handling of traffic, 802.11ac Wave 1 or 2 radios take advantage of the speed boost. It will be waste of money if you use older, legacy WiFi end devices. Also supports reliable long range transmissions. Works in the areas of multiple obstructions.
