Have you ever asked yourself the question: How does wireless Internet work? In this article, you could find out more about four ways to establish a wireless connection to the Internet – Mobile wireless internet, WiFi internet service, Internet access using WiMAX solution, and Satellite Internet wireless access. To explain how does wireless Internet works let’s find out what is wireless internet. Wireless access is a connection to the Internet without any cables. Between your computer and the internet provider, it is a wireless radio signal. There are four main examples to use this kind of connection:
1) Mobile wireless internet
Mobile network operators are offering you voice calls, but at the same time, you could use their mobile wireless internet service. All-new mobile phones have the option to connect to the Internet. They also have the ability to use WiFi access. When you are between your home wireless router or WiFi hotspot, the best is to use WiFi technology. In the other cases, you could connect to the Internet with a mobile wireless internet connection. There are also Cellular wireless cards, usually with USB or PCMCIA connectors which you connect to the appropriate port on your PC. Thanks to them, you could surf the web and check your emails. GSM and CDMA connect you to the speed of 9.6 kbps, GPRS has a transfer rate of 114 kbps, EDGE up to 384 kbps. UMTS allows you the speed of maximum 2Mbps, and HSDPA’s maximum bandwidth is 42Mbps. To answer how wireless Internet works, we need to explain other ways to use the internet without cable.
2) WiFi internet service
For WiFi internet, you need to use the Wi-Fi providers. The biggest problem with the WiFi is it does not have a big range as mobile operators do. WiFi or wireless fidelity refers to the wireless networks that use IEEE 802.11 WLAN standards – 802.11a, 802.11b, 802.11g, and 802.11n. These standards define a wireless signal connecting between the wireless access point or wireless router and WiFi cards. WiFi technology is also called a WLAN or wireless local area network – Wireless LAN. This technology is the first that usually comes to my mind when somebody asks me how wireless Internet works. Its quality, speed, and features bring WiFi to the top of all ways to achieve internet without the cables.
3) Internet access using WiMAX solution
WiMAX forum has formed IEEE 802.16 standard called Wireless MAN. WiMAX technology or Wireless MAN has a bandwidth of 70 Mbps with a maximum range of 112 kilometers or 70 miles. Wireless MAN (Metropolitan Area Network) covers a bigger range than WLAN (WiFi). WiMAX solution has two types of subscriber units: Indoor units and Outdoor units. Indoor units have a lower range than outdoor units. Outdoor units need a professional installation, and they are much more expansive, but they offer a wider range. WiMAX technology is much more expansive than WiFi, so WiFi is much more widespread than WiMAX.
4) Satellite internet wireless access
By now, you get the feeling of all these various technologies, and you know how wireless Internetworksk. With this technology, we will cover the most popular internet connections without wires. Satellite is the perfect solution for remote and rural areas, and it is the only way to achieve broadband internet. Besides the big expense, the big delay caused by the huge range that this kind of signal needs to travel is the biggest disadvantage of this solution.
