This is an analyst angle articlewhich explains the important reasons or factors for the best Wi-Fi experienceand use of the factors like where & why we need them? Mainly the articleconcentrates on the increase in the data usage through the Wi-Fi than the LTEby user. From the CISCO reports we can see how badly the users are dependent onthe Wi-Fi than the LTE, nearly 11 Exabyte per month (1EB = 1billion gigabytes)which is hell of a lot of data. In order to maintain such high data stream we needtop end speed performance which turns our heads to the 802.11ac which providesa high throughput WLAN’s such as 1 GB/s on multi station link and at least 500MB/s on single link. In order to achieve such high throughput we need to have ahigher network manageability, efficiency and capacity which is provided by the802.
11 k, v and r standards. The above standards are about how a client canchange from one AP to another AP while in motion and how the change occurs. The802.11k deals with choosing the best AP when surrounded by a lot of AP’s. Itfollows a certain steps to choose the best one, first it is connected to APwhich has the best signal strength by using probe signals – asks the connectedAP about other nearby AP’s – it gives a neighbor list – based on the list itswitches to the next best AP nearby. The 802.11v deals with the clients inmotion/roaming.
When the client is in motion the connected AP will have a lowsignal strength, it then warns the user about it and also gives information aboutother AP’s nearby which has a strong signal strength. This removes the notionof the user connected to a default AP with a low signal strength. The 802.11renables fast roaming when the users are connected to different AP’s on the samenetwork, it provides a sort of authentication shortcut where the device neednot have to disconnect and connect back from changing from one AP to another,which reduces the reconnection duration and enhances the user experience. Allthe above factors enhances the network efficiency, maintenance and capacitywhich in turn enhances user experience.
