What is the best modem or transmitter for mobile broadband?
This depends on your situation. Probably the most convenient is a fully integrated chip in a notebook computer, which is concealed inside the computer’s casing. However, this might require buying an entire computer. PC card solutions have excellent performance and are the next best thing, fitting snugly into the computer’s PC card slot. Finally, USB modems have equally good performance but the way they dangle off the body of the computer can be irritating. On the upside, they can be easily connected to desktop computers as well as notebooks.
