WiFi is just great – when you can get it. While roaming the streets of New York or some other metropolitan area you might need to get online but do not have wireless internet access via WiFi and most likely not dial up (when’s the last time you saw a spare phone line available for use?).
One option is wireless access via a cellular provider.
The NY Times writes …you can use wireless data networks offered by cellular providers, but they have been slow – only two to three times as fast as dial-up modems. Now broadband service (about five to nine times as fast as dial-up, with high-speed downloads available in bursts) is available from Verizon Wireless for $79.99 a month.
Operating on different standards from Wi-Fi, the broadband services require special modems that plug into a laptop computer’s PC card slots.
