Computer Information on Wireless Internet

Wireless Internet gives computer users access to the Web without plugging in.

When the Internet first gained widespread popularity in the 1990s, users needed to plug in through a modem at home or at work. Early broadband service continued this trend. But today, many users access the Internet wirelessly. This type of connection requires special technology to work and gives users several key advantages.

Types

There are several distinct types of wireless Internet. The most common is Wi-Fi, which stands for wireless fidelity. This service is closest to a conventional wired Internet connection in terms of speed and reliability. 3G and 4G wireless Internet use advanced telephone networks to deliver Internet content to smart phones and other Internet-enabled mobile devices. Satellite Internet provides connections for users who live or work in remote areas where cable lines or cell phone networks may not exist.

Technology

Each type of wireless Internet uses its own form of connection technology. Wi-Fi networks rely on existing wired networks, adding a wireless router that broadcasts a short-range wireless network for users in a home, office or public building. 3G and 4G service uses cell phone towers and airwaves to send Internet content over longer ranges, but at slower speeds. Satellite Internet is based on a constellation of Earth-orbiting satellites that constantly receive data from terrestrial sources and relay it to connected users.

Setup

Setting up wireless Internet service varies based on the service provider and the type of connection. To establish Wi-Fi service, users must first have Internet service through a broadband provider, then install a wireless gateway or router to broadcast the local Wi-Fi network. 3G, 4G and satellite Internet service usually requires its own subscription, and users are more likely to pay based on the amount of data they download and upload. In all cases, wireless-enabled devices are essential. Most modern cell phones, notebooks and desktop computers all have built-in antennas to receive wireless Internet signals.

Advantages

Wireless Internet access has several important advantages. The biggest of these is mobility. Users with a notebook computer can work anywhere in a home or office where a wireless network is active. Users can stay connected when they take their computers to coffee shops, libraries and other public spaces where free wireless networks are common. Finally, wireless Internet removes the need to install physical wired networks, thus reducing clutter and lowering costs for businesses and educational institutions.

Drawbacks

Wireless Internet is not without its drawbacks. One of these is the concern about security. With a great deal of important information passing between computers and networks wirelessly, the opportunity for unauthorized access to that data increases. Without proper encryption, anyone with a wireless connection can potentially access the information that is transmitted wirelessly, compromising the security of users.
