Access wireless (or WiFi) Internet, sometimes referred to as Hot spot, is a network of local area (network LAN) in charge of by radio instead of wires. Wireless Internet access spreads from a central point, which is a device of wired logic that is really that brings the connection to the Internet. In households, a system configuration of desktop for wireless access to the Internet shall deliver connectivity to the entire residential area immediately. Any member of the family with a laptop or desktop in another room can connect wirelessly to the Internet to share the main connection. Neighbors can also have access to this wireless connection, so the majority of wireless LAN networks are configured with security passwords.

In this case, any computer that you want to obtain wireless Internet access must establish the LAN connection, and then request the password. If the correct password is not supplied, it It will deny access to the internet. Security for wireless access to the Internet protocols have improved thanks to the options: Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access 2 (WPA2). While Wifi access to the Internet is very convenient in the home, it may be even more in the workplace. A network cable not only will take a long time to install over a building but is also very expensive.

Ethernet cables used to connect the equipment of the customers to the Internet must be routed through walls, ceilings and floors for people with advanced knowledge in types of network and computer networks in general. These advantages have been mitigated to a large extent through time. Follow others, such as Nicolas Keller, and add to your knowledge base. Wireless LANs can be installed in a few minutes and practically by any person with knowledge minimums in systems, they are very cheap, and they can have information transfer rates that rival wired Ethernet LAN. On the other hand, WPA2 encrypts all traffic on the LAN, tackling the problem of computer espionage. One of the applications most popular for wireless access to the Internet is the Hot spot public. Internet cafes are an example of the places where one can sit with a coffee and enjoy a portable computer while you browse the Internet, check email, or doing a school research. Cell phones and personal digital assistants (PDAs) are equipped with Web browsers which can also be used in these hot spots public Internet access points. Some places offer free Internet access Wi-fi for residents and visitors. Given that wireless LAN networks use radio waves to long distance-distorting, but the radio signal is limited. The farther you are from the Center main, weaker it will be signal. Cities that provide this access should therefore cover a specific area within the city where people can park or Park to gain access. Wireless LAN technology is constantly improving. When designing a new wireless network, the person responsible for the creation of the network must be safe have network cards, a strategic point, and a wireless modem that supports the latest protocols and all security measures. Instructions should be carefully followed the hour to set up wireless Internet access.
