An AirCard® modem allows wireless Internet access via a cell phone network. It is small and portable, but tied to specific carriers and requires a service plan. Charges can be high when using it internationally or in roaming areas.
An AirCard® modem allows people to connect to the Internet via a broadband wireless network typically used for cell phone service. AirCard® is actually a brand name for several devices that a person can plug into their computer’s USB port or PCMCIA slot to access the web in this way. All AirCard® devices are distributed by Sierra Wireless. Other brands of mobile broadband devices are available.
The advantages of an AirCard® modem are many. The most important is that the user can access the Internet from anywhere where there is cell phone service. This gives it much more freedom, since you don’t need to connect your machine to a landline or find a Wi-Fi hotspot. It’s important to note that, right now, most AirCard® modems are tied to specific cell phone carriers, so someone with an AT&T AirCard® wouldn’t be able to access the Web in an area where only Verizon has a network, e.g. example. The user must also purchase a monthly service plan in order to use AirCard®.
Another advantage of an AirCard® modem is that it is small and portable. Most are roughly the same size as USB drives or network cards, with a length and width of less than 6cm. They can easily fit into a pocket or laptop case. You can also purchase an AirCard® case and attach it to a key ring.
To set up an AirCard® modem, simply install the software that came with the modem and use it to access its wireless service. The modem will only work with specific software, so there is not much choice in this matter. With the software configured, a person can access the Web as long as the AirCard® is securely plugged into the appropriate port or slot on the computer. Many USB-type AirCard® modems actually turn on when properly connected. This can help greatly with troubleshooting.
One thing to remember before using an AirCard® is that because these modems connect via cellular networks, charges can be higher when connecting internationally or even in roaming areas. Be sure to ask your wireless carrier about calling plans before using the modem. Otherwise, you may be stuck with a huge account.
