An AirCard® antenna increases a computer’s ability to connect to low-power signals and maintain the connection. It can also increase speed and improve signal stability. The antenna is an external unit that plugs into the AirCard® and does not require any software to operate. There are different types of antennas, and it is important to ensure compatibility with your computer before purchasing.
When a computer, usually a laptop, needs a wireless Internet connection, it can use an AirCard® drive to establish a wireless connection. Under normal conditions, the AirCard® will be able to connect easily to the Internet when there is a hotspot nearby. If your computer is located outside the hotspot, the AirCard® may not be able to connect. This is where an AirCard® antenna comes into play. Like other antennas, an AirCard® antenna increases your computer’s ability to connect to an Internet signal.
An AirCard® antenna is used to increase the computer’s ability to connect to low-power signals and to maintain the connection. While this is the main purpose of using an antenna, it also offers many other benefits even if the signal strength is good without the antenna. It can increase speed, which is also useful in areas with high signal intensity, and improve signal stability.
The AirCard® antenna is an external unit and is never used internally, as it would not fit inside the computer. Most AirCard® units are not equipped with an antenna; rather the antenna is a separate unit that plugs into the AirCard® and is typically purchased separately. This connection is made by twisting a coupling unit or by simply snapping it onto the AirCard®. Antenna installation is usually simple and takes only a few seconds.
When you add new hardware such as a mouse or printer to a computer, the computer usually needs drivers or special software to use the hardware. Unlike these hardware units, an AirCard® antenna does not need any software to operate. It’s made to work as soon as it’s plugged in, so the user doesn’t need to enable the antenna or install any software.
Some AirCard® antenna units come as a small stiff antenna, while others come as a long soft antenna. Small, stiff antennae are typically about 1 inch (about 2.5 centimeters), while soft antennae are much longer. Soft antennas usually come with Velcro® attachments so that the antenna can attach to the back of the computer without hanging off the side of the car and getting in the way.
Most AirCard® antennas cannot be used for every computer or AirCard® unit. There are typically several AirCard® units that a particular antenna can work with. Before purchasing an antenna unit, it is best to determine if the antenna works with the AirCard® on your particular computer.
