Wi-Fi Hotspot

Wi-Fi is a venue or place that provides Wi-Fi access. These locations can be School campus, Restaurant, Library, Railay station, etc where the public can use a laptop, Mobile phone, or another suitable device to access Wi-Fi.

WiMax

WiMax is a wireless digital communication system. WiMax can provide broadband wireless access up to 30 miles (50 KM) for fixed stations. WiMax requires a  tower called base station similar to a cell phone tower. WiMax is more secure, can cover more area, and can provide more internet speed than a Wi-Fi.
