WiFi:
WiFi stands for Wireless Fidelity. WiFi uses Radio waves to provide wireless high-speed internet and network connections. A WiFi connection is established using a wireless adapter to create hotspots. WiFi antennas size small enough to ne placed on a very small router. WiFi can be used to connect with printer, computers, gaming consoles and many more.
WiMax:
WiMax stands for Wireless Inter-operability for Microwave Access. WiMax uses licensed or unlicensed spectrum to deliver connection to network. WiMax handle a larger inter-operable network. WiMax can be used to provide internet services such as mobile data and WiFi spots.
Difference between WiFi and WiMax:
| WiFi | WiMax |
|---|---|
| Wifi is defined under IEEE 802.11x standards where x stands for various WiFi versions. | WiMax is defined under IEEE 802.16y standards where y stands for various WiMax versions. |
| WiFi is for LAN (Local Area Network) applications. | WiMax is for MAN (Metropolitan Area Network) applications. |
| WiFi does not guarantee any Quality of Service (Qos). | WiMax guarantee Quality of Service (Qos). |
| WiFi network range is around 100 meters. | WiMax network can reach about 50-90 km. |
| WiFi MAC layer uses CSMA/CA protocol which is not connection oriented. | WiMax is connection oriented in nature. |
| WiFi is short range technology. | WiMax is long range technology. |
| WiFi connection can transmit upto 54 mbps. | WiMax connection can transmit upto 70 mbps. |
