How Does Wireless Internet Work?

Wireless Internet works in the same way as wired Internet. Internet is a worldwide network of wireless networks, which enable the exchange and communication of information and communication on the web. The main difference between wireless and wired Internet is the presence of wireless networks in some places and pockets of the world such as in vehicles and airplanes and on some topographical features such as mountain or building peaks. Wireless internet and Wi-Fi the same thing?

Wires are the physical layer that conveys data signals between hardware devices and software applications on physical or logical layers. There are four layers in the physical layer of an Ethernet cable. The first layer is the Ethernet cable itself, which encodes the information that is to be conveyed; the next layer is the data channel, which is composed of several transmitters and receivers that receive and relay the data from the first layer.

The last layer is the security layer, which disables or enables the software and hardware components of the network to access the internet without first obtaining a security code, which is unique for each device.

WiFi is an acronym for Wireless Fidelity, a set of radio signals that enables your laptop to connect to wireless internet using a PC. These signals carry much more power than regular radio signals and can travel longer distances. Wireless internet is enabled with a wifi connection card, which translates radio signals into wifi signals, and vice versa.

How does wireless Internet work?

The basic technology used for this is Wi-Fi, also known as Wireless Fidelity. A laptop connects to the internet using a computer with a wifi card. The laptop searches for an SSID (stand for System Server Identity) on a pre-existing network that uses an SSID.

There are three types of wifi routers. One is the AP (wireless access point), a second is the WEP (wireless Equivalent Privacy), and a third is the Wi-Fi Protected Access. With the latter, an SSID is required but with the former, a wireless router is sufficient. After configuration, you can establish a wifi connection from your computer to the internet service provider’s router, or directly to the actual wireless router.

How does a WEP work? Wireless Equivalent Privacy (WEP) routers encrypt their signal so that only authorized users can read the transmitted data. To send a message, the user connects to the WEP-enabled client and passes a secret key. Only when the user believes he/she is talking to a real person, will the message get sent. As soon as the message is received, it gets encrypted and converted into a ‘secret code’ that only those with the key can read.

In the absence of a WEP key, the wireless signal deciphered by a sniffer is the only way to connect to the internet using the given SSID. The advantage of this method is that you can monitor your kids, whether at home or in the office, while you are not present. You can log into your system from any location, using any password, and access all your files. These devices are also used by hackers to track your online activities.

In a nutshell, to make sure that your kids do not gain unauthorized access to your computer systems, you need to configure your computer settings such that it cannot be tracked or captured. This can be done using an online security provider such as encryption. Once your child has his/her own laptop, he/she can log on to any wireless hotspot and access the web wirelessly. Do not forget that wireless internet work is cheaper than a wired connection and it gives unlimited accessibility.
