The presence of Wi-Fi in various devices now does not surprise anyone. Manufacturers try to meet the needs of potential buyers as much as possible. However, not everyone uses the full technological potential of modern devices. Someone unnecessarily, someone just does not know how. Today we look at what Wi-Fi is, where it came from on our head, why it is needed and how to use Wi-Fi networks. The more we know, the better our life. Recommendations on how to use Wi-Fi can be useful to everyone who takes the first steps in this direction.
Start over. Wi-Fi (pronounced Wi-Fi) is a way to transfer data without using a wired connection. Its second name is the IEEE 802.11 standard. The letters b / g / n indicate the data transfer rate. Originally created for the maintenance of cash systems. Now it is widely distributed and massively used in offices, public places (cafes, train stations, libraries, airports), in private homes for wireless Internet access. This is if very briefly.
Why is it needed. Most modern devices: computers, laptops, tablets, communicators, smartphones - have a Wi-Fi module “on board”. Moreover, Wi-Fi is now actively being used in printers, cameras, video surveillance systems and other devices that need a reliable channel for data transfer without the help of wires. It's comfortable.
You can accept / transmit any information. The range of local networks depends on the power of the transmitter and the presence of interference in the signal path (walls, buildings, trees, terrain). Home access point provides an excellent signal level within any apartment. This makes it possible to get rid of the wires and establish the full-fledged work of several users at once.
How to use Wi-Fi?
This method of data transfer is now mainly used for Internet access. A special device (router / router) creates a local network and “distributes” the Internet via a wireless protocol. Access to the local network can be free for everyone (insecure network), and password protected (secure network). You can connect to this network using the Wi-Fi module on your device. After connecting, you get full access to the Internet. The speed of your access will depend on the speed of the incoming connection and the total number of connected devices.
Wi-Fi networks: how to use the owners of mobile devices
Despite the “many BukAff” in the previous paragraphs, everything looks simple and convenient for the user. Turn on Wi-Fi on your device (laptop, tablet, smartphone) and your gadget will automatically detect all networks that are within the range of access. To connect, select the network from the list. To connect to a secure network, a password is required (ask the owner / administrator of the network), an unsecured network does not require a password.
How to use Wi-Fi in public areas
It is not in vain that an open network for general use is called an insecure network. This means that other users can see the data that you transfer. This moment must be kept in focus if you enter passwords to access your accounts, payment documents or simply do not want to let anyone into your personal life. This does not mean that everything that you wrote, said or looked at will immediately become the property of intruders. But there is such a possibility.
How to use Wi-Fi at home
If you want to use the benefits of progress at home - make sure that lovers of "freebies" do not use these benefits together with you / instead of you. Be sure to password protect your network. Otherwise, anyone can easily connect to your home network, and you will have to pay for all the "uninvited guest" traffic from your pocket. Even if you have unlimited Internet access, you risk losing speed and giving access to your confidential information.
There is a saying: warned - means armed. This, of course, is no reason to become paranoid and everywhere to see spies in the company of pests. One thing is clear: an understanding of potential risks and minimal precautions will save you nerves and money, and also make you feel safe.
