The air card is a formerly trademarked term that now refers to any connection device that allows a mobile computing platform to access the Internet through a cellular network. Using a signal and a set of protocols, an air card can turn your tablet or laptop computer into a mobile office that lets you share and create most anything of interest. The best way to connect an air card nowadays is through the USB port.
How Air Cards Work
An air card is simply a device that is able to send and receive the signals from a wireless form of Internet other than wifi. while a wifi signal is generally very localized and not particularly strong across distances, a cellular network can function for tens or even hundreds of miles. Much like how cell phones in the modern world almost never lose service unless you are in a highly rural area, a cellular Internet network will keep you online most anywhere. Air cards work by connecting you to the Internet this way, rather like an antenna connects radios to one another.
Using a very dense signal, wireless Internet networks such as 4G allow you to access all of the content on the Internet as easily as you can hear a phone call or receive a text message on your phone. The data sent and received is cataloged based on an ID the network assigns the device, and in this way the transition into the network is quick and seamless. The data plan requires a connection that may involve unlocking your air card, and there is often a monthly service fee associated with using an air card in the same way that cell phones require you to pay for the service.
USB or universal serial bus ports have been a common component of most computing devices for many years, and they will most likely continue to be a ubiquitous part of the computing world. These ports are used for connecting all sorts of devices into your laptop, but air cards are perhaps the most useful of these devices. Through your air card and its convenient USB connector, you can access everything online as easily as if you were on your home or office wifi connection. In some cases, the connection is an even faster one than you would get at home or in the office.
The Mobile Office
Your laptop or tablet PC can become a sort of mobile office. By linking a USB air card into your device, you can connect to printers in offices far away, send and receive emails from people all around the world, have conversations via chat and even web based video, and research any topic that the Internet has any information about. Your ability to get work done on the road is incredible through the use of these networks.
Connecting To Any Network
A network connection requires a great deal of coordination, and for most users this process is transparent and simple. You need only purchase an unlocked air card, or a locked card that works with the network you wish to use, pay your subscription cost and log in at least one time. However, the process of actually connecting a device into a network that in turn connects to virtually every other device in the world is not simple. There are numerous protocols that need to be fulfilled and a great deal of quantification involved in this process.
