Most of us have cell phones that can send and receive email.  Now let's take that a step farther, and allow the whole boat to send and receive data!

Cellular data routers (like the Cradlepoint shown at the right) move data only.  They allow you to choose an Express card or USB adapter from your favorite cellular provider.  You can expect speeds around 400kbps from the current 3G networks.  4G networks should exceed 1Mbps!

Cellular terminals (like the Ericsson W25) can do both data or voice.  Of course, voice always wins, so if you are moving data, and a call comes in, the data will pause.  Cellular terminals are GSM only, and cannot use a USB or Express card.

A cell terminal normally has one RJ11 for voice to the PABX, and 1-4 LAN jacks for data traffic.

It goes without saying that you must have a 'tethered data plan' from your cell provider.  These are normally $60 a month.  Also note that most cell providers have a 5GB per month cap, so watch your amount of traffic you move.
