What is Mobile Broadband

A Mobile Broadband network, also known as a Wireless Wide Area

Network (WWAN), provides Internet access to laptop computers, cell

phones and other devices over a large geographic area. Cellular networks

are used for data transmission, and access is usually provided by a mobile

network operator.

The biggest advantage of Mobile Broadband is that it is accessible from

anywhere you can get a signal from your carrier. Laptop computers with

Mobile Broadband access can stay online on the move, and will not be tied

down by a wired Internet connection.

Various standards are in use by mobile operators to provide Mobile

Broadband service. Depending on the model, your Mobile Broadband

module may support one or more of the following standards:

 GSM (Global System for Mobile Communications)

 TD-SCDMA (Time Division-Synchronous Code Division Multiple

Access)

 SCDMA (Synchronous Code Division Multiple Access)

 EV-DO (Evolution Data Optimized)

 HSPA (High Speed Packet Access)
