A wireless air card, or Internet card, is a card designed to help a computer connect to a cellular telephone system for communication with a network, most likely the internet. It is advantageous to the user in that it can be used to connect to the internet when there is no other way to do so. This card can be a convenient tool for those who are dependent upon multiple computing and need that connectivity.
While notebook computing has always been a convenience, there have always been some limitations, especially when it comes to internet access. Wireless internet access can include many ways of getting online. WiFi is, perhaps, the best well known of all the internet connections. However, WiFi has some very severe limitations. While it is ideal for those who can count on being in one location for a significant period of time, it is nearly useless for those who find they will be doing a lot of moving around.
However, a wireless air card, which uses cellular phone frequencies, has a much broader range. In fact, nearly anywhere where a cellular signal can be obtained, a this card may be used. However, it can only work if the cellular network supports not only voice transmission, but data transmission as well. There are other things to consider about Internet cards as well.
The main consideration is that different air card types work with different types of technologies. The technology that is compatible with some types of systems may not be compatible with other types. Therefore, check with your cellular provider to see what types of cards may work in your area. The cellular provider should also be able to provide you with a map of coverage throughout your country, and perhaps the region.
The wireless air card will only work for those who are subscribed to the network. Therefore, such a card will often require a monthly subscription fee. However, there may be other payment arrangements which are acceptable as well. Though the first ones may have started out only allowing a certain number of hours per month, the standard now is for unlimited access.
For those who are looking for a wireless air card, the best bet is to check with your own cellular provider. That company will often be the best choice and may even offer a discount on a package deal. Those who choose a wireless air card may opt to cancel a traditional internet service, as the connection is often comparable.
