All about WiFi
What is WiFi?
Wi-fi is nothing but a standard for building wireless networks. The big advantage of the wifi network is undoubtedly the lack of cables that are required in traditional LANs. Many of the restaurants or cafes provides free hotspots so that we can take advantage of free internet access. Many people and companies are also in their home Wi-Fi network, which is usually protected by a password. Therefore, with such a secure network we can not call unless we use a special program which is available on this website. Laptop on the couch, Internet radio in the kitchen near a TV network player and smartphone in the bedroom – all these devices can connect to the Internet using a wireless Wi-Fi network. Unfortunately, not always the connection speed will be satisfactory for us – it all depends on the standard Wi-Fi networks. Currently, the fastest and the most popular is the standa
Standard A (802.11a) – very rarely used standard for wireless transmission at a frequency of 5 GHz. This allows the theory to achieve the speed of 54 Mbit / s
Standard B (802.11b) – this outdated standard can transfer data at a theoretical maximum speed of 11 Mbit / s at 2.4 GHz. Currently, the principle is not used.
Standard G (802.11g) – a standard typical for older laptops and cheaper routers, and many do not require high-speed data network equipment. Operates at 2.4 GHz and can achieve a maximum theoretical data transfer rates of 54 Mbit / s
Standard N (802.11n) – currently the most popular version of the Wi-Fi network – depending on the solution (used antennas) allows you to transfer files with lightning speed (theoretical) – from 150 to 600 Mb / s The notebooks and more expensive routers is usually a variant 300 Mb / s Latest, most business laptops, are already prepared to handle a faster version of the standard N – typically 450 Mb / s Standard N can operate on both the 2.4 GHz frequency, and 5 GHz. However, the vast majority of devices can transmit and receive data only in the 2.4 GHz band, the higher the frequency of the most expensive routers support and well-equipped notebook PCs and other devices connected to the network. Importantly, even older devices that support only standard B or G can be used with the router acting as a standard N, but in this case, the router switches to a slower pace of standard B or G.
Free program WirelessNetView search for wireless networks in range of your computer and displays them on a very detailed information. The tool, in the form of a table, it shows the SSID, the percentage range of connection, information about security and authentication type.
In addition, the program displays information about your recent calls and average statistics on the time and intensity of the WiFi signal. WirelessNetView appreciate the fans of the console. The support of the latest version can also use commands to the command line.
Retina WiFi Scanner 1.0
Retiny scanner is one of the most recognized products in the company, which manufactures the application of the general network security. Thus, the tool can be expected a little more than just the ability to detect wireless networks.
Retina WiFi Scanner after finding available wireless networks generates very clear reports with information about the SSID, time, recent calls, and more. It can be used in the other direction – that is, to see if someone is not trying to, during holiday travels, plug in without permission to your network.
Easy WiFi Radar 1.05
Easy WiFi Radar presents a new approach to detect wireless networks than the two above mentioned tools. The program’s interface resembles just plain … radar. Operation is very simple, because it comes down only to run the application. After a while you will see the results on the animated radar window. Then you can try to connect – by pressing one button.
After a successful connection, below the radar window, displays detailed information about the network. Easy WiFi Radar can definitely recommend the users who just want to find access points, and are not interested in advanced statistics or information on WiFi security.
