What is wireless Internet access?
Wireless Internet access, sometimes referred to as "hot spot", if the public is available, the local network (LAN) is operated by radio waves rather than wires. It is broadcast from the central hub, which is a firmly connected device that actually brings an Internet connection. Located in the main computer system or server , it broadcasts an Internet connection with clients , which includes virtually anyone in the range of reception, which is equipped with a wireless card and password to the network if secured.
In the home, setting up the desktop system for immediate access to the immediate area is transmitted in the immediate area. Each member of a notebook family or desktop computer in another room can wirelessly connect to the Internet and share the main connection. Neighbors can also have access to this wireless connection, and therefore most wireless ropes are configured with password security. In this case any machine thatErý wishes to connect wirelessly first complete "Handshake" with LAN where the password is required. If the correct password is not delivered, access is available. Security protocols have improved using Wi -protected access options (WPA) and Wi Fi -protected 2 (WPA2) .
While wireless Internet access is very comfortable in the home, it can be even more in the workplace. The cable network can not only be very time consuming installation throughout the building, but is also very expensive. Ethernet cables used to connect client machines may need to be directed by walls, ceilings and floors. In the past, this disadvantage was sometimes overlooked due to the advantages of greater security and faster data transfer through these cables.
However, these advantages were largely alleviated. The wireless Lans can be installed virtually almost anyone, they are extremely cheapV, and may have data transmission speeds that compete with a firmly connected LAN Ethernet. In addition, WPA2 encrypts all ropes on LAN and deals with the problem of eavesdropping.
One of the most popular applications for wireless Internet access is a public hot place. Internet cafes are one example of places where you can sit with a laptop and sip coffee while sailing on the Internet, check e -mail or research. Mobile phones and personal digital assistants (PDA) equipped with web browsers can also use these access points through public hot spots.
Some locations provide wireless internet for residents and visitors. Because wireless ropes use radio waves that distort long distances, the radius of the signal is limited and the further away from the charge, the weaker the signal. Therefore, cities that provide access usually cover a specific area in the city where people can park to get access.
Technology for BEzhdrate ropes are constantly improving. If the new wireless network, the person who sets it, should surely have network cards, a hub and a wireless modem that supports the latest protocols and security measures. In the configuration of the wireless network, instructions should be carefully followed.
