Smart wifi basics
This page describes Smart WiFi basics. It covers operation of Smart WiFi network.
The term wifi refers to the wireless internet service provided by WLAN network. In WLAN network there are two main components viz. AP and STA. AP is known as Access Point or router which has connectivity with backbone internet. STA is known as STATION or client which utilizes services of WLAN router or AP to browse the internet. Initial WLAN network was developed based on IEEE 802.11a/b/g. Later on devices based on IEEE 802.11n were introduced.
Now-a-days WLAN devices based on IEEE 802.11ac and 802.11ad are available. The network made of these standard based wifi devices is known as Smart WiFi network and devices are referred as smart wifi devices.
Smart WiFi Network
The figure-1 depicts typical Smart wifi network. The smart wifi has connectivity with both cellular as well as wifi network devices. This concept will help offload cellular traffic on wifi network. WiFi hotspots will help in this regard.
Following the features of smart wifi network:
• Support more number of wifi devices.
• Support voice calls over wifi links.
• Support high version of IEEE WLAN standards viz. 802.11ac,11ad etc.
• Provide connectivity with cellular networks such as LTE, LTE-advanced etc.
• Incorporate multiple antenna concept such as AAS (Adaptive Antenna Scheme).
• Introduce high quality of service as defined in IEEE 802.11e.
• Creates high speed mesh network using latest RF routing concepts.
• Introduces advanced security features.
• Utilizes new techniques for channel selection.
Refer 802.11ac and 802.11ad tutorials for more information on IEEE 802.11ac and 802.11ad standard features.
