The capabilities of cellular networks have improved greatly since their original development for analog voice phone calls. Most recently, fourth-generation (4G) wireless supports a variety of data-intensive needs. A benefit of 4G networks is that they: 

Use spread-spectrum technology to ensure high transmission rates. 

Provide fast transmission rates equivalent to DSL or broadband-cable. 

Provide fast transmission rates equivalent to high-speed dial-up connections. 

Enable bandwidth throttling, allowing the user access to unrestricted download speeds.
