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:
ƒ GSM (Global System for Mobile Communications)
ƒ TD-SCDMA (Time Division-Synchronous Code Division Multiple
Access)
ƒ SCDMA (Synchronous Code Division Multiple Access)
ƒ EV-DO (Evolution Data Optimized)
ƒ HSPA (High Speed Packet Access)
