Question: What is WiMAX?
WiMAX (Worldwide Interoperability for Microwave Access) is the wireless technology based on 802.16 standard. It's also called 4G sometimes. It works pretty similar to wireless network, but with much bigger coverage (quite similar to cell phone network coverage), higher speed and greater number of users supported. That's why it's suitable to be used as broadband wireless access service in rural areas that lack of DSL/Cable broadband service.
In order to connect to WiMAX network, the most convenient way is to install a PCI card or USB dongle on the computer to connect to WiMAX transmitting station. Also external WiMAX antenna can be installed to connect to WiMAX network.
