How Does Wireless Internet Work
How does wireless internet work? Wireless networking is all around us, it is WiFi or also called 802.11 networking. One day wireless networks will be every where. No longer will the need be to use ethernet, cable connections. WiFi is what makes wireless internet possible. It is just like radio waves, but with two way communication lines. Its radio waves are similar to the wireless cell phones, radios and television.
- Wireless adapter. The wireless adapter is either built into the computer or you have a wireless adapter installed. The wireless adapter receives the data and translates it into radio signal and transmits it through the wireless antenna. The plus of having a wireless adapter is you don't have to plug into a hub, router or telephone line. Just go to any room in the building and connect to the internet. Anyone else that would like to connect their computer to the internet doesn't need to plug in to anything. They just search for network and connect to it and they are ready to use the internet too. If the wireless internet system has a security password they will need it in order to be able to connect to the wireless network.
- Wireless Router. A wireless router receives the message and then decodes it. It then sends the information to the physical part of the ethernet wired modem, hub or router. It goes through the same process when sending information over the internet, but works in reverse from the receiving process. This translates it in to radio waves and transfers it to the wireless adapter. It transmits at different speeds, some transfer at a frequency of 2.4 GHz and 5 GHz, which is much higher frequency then that of a cell phone, radio and television. The networking standard is 802.11, which has several variants. To name a few: 802.11, 802.11a, 802.11b and 802.11g. The order is from slowest to fastest.
