How a WI-FI works.

Most computer users understand little about how Wi-Fi operates. Wi-Fi is a popular technology that offers interconnectivity between devices. Way to connect to the world wide web, since for many people it is the network that they use at home or in the office,” says Wi-Fi Alliance CEO Edgar Figueroa. “But, Wi-Fi has evolved and today it is a replacement for many distinct cables like video cables, audio cables, USB cables.”
Wi-Fi carries radio waves, and it’s a bit more complicated than your automobile stereo. Wi-fi is different than the FM in someone’s car; it is basically two radios communicating back and forth that uses a much lower frequency with shorter distance. Both radios allow web users to get data from the web in addition to upload info — even simply submitting addresses through your browser counts in this two-way communicating.

Another way Wi-Fi is much more sophisticated than terrestrial Radio is the fact that it uses the Internet Protocol to convey. This language of the web makes Wi-Fi very resilient and very organized. “It requires a whole lot of investment and orchestration.” Imagine rather than sending data; you are shipping a package throughout the world with request for shipping confirmation says, Figueroa. That is exactly what the Internet Protocol is similar to; only it applies to each and every byte transmitted.
According to physics, the lower the frequency, the further a transmission can proceed. With Wi-Fi, 2.4 gigahertz is the reduced frequency so that it can reach computers located further away than compared to 5 gigahertz band can. But five gigahertz deliver the capability to carry more transmissions. “Imagine if you had a highway which went really far but it was just a one-lane street,” says Figueroa describing 2.4 gigahertz Wi-Fi. By comparison, five gigahertz Wi-Fi is a highway which does not go as far, but it provides six lanes, so it could make traffic move faster.
“Five gigahertz Wi-Fi provides enough coverage concerning area it may cover the whole house,” he says. “So, for many people, space isn’t really as much of a problem as the rate.”
But ever since the era of cordless telephones, people have had the issue continues now with neighbours and their Wi-Fi networks. One way to avoid this is by placing your frequency to broadcast on a specific channel. While this sounds technical, it is not. And five gigahertz networks have a lot more stations than networks broadcast on the 2.4 gigahertz frequencies, another reason to use the new standard if you’re able to.

Network is a much better idea than just installing a network extender. “Network extenders are gaining popularity,” says Figueroa. “They are repeaters, so that they take what could be a faint signal coming from upstairs to the downstairs surroundings and then, basically, they are repeating that sign.” However, the problem with those extenders is they propel an already weak signal. Thus, in case your Wi-fi is transmitting at half-speed that it should, the extender will duplicate that sign, pushing out an even weaker signal. An individual standing right next to the extender will have full network as he/she might have a powerful signal but the internet speed is still slow and poor.

Wi-Fi also has a variety of security features. To access the network, users need a password for WPA2, also called Wi-Fi Protected Access (the two represents the fact that this attribute is in its second generation). There is another safety feature called Advanced Encryption Standard (better called AES) that was designed from the U.S. government to keep data secure as it transports from one device to another.

It is backwards compatible. This is how all your older computers can Connect to your brand new, super-fast routers. Nowadays, it works for this device you might have purchased back in 2000,” says Figueroa. “There are not too many technologies which you could say that about.”
