How do you provide a decent speed internet connection to multiple devices on a USA road trip? (either on interstates, in campgrounds or hotels)
Four people have at least 2 devices the following (total 11 devices), but up to 5 active at any given time.
Use Mifi
Mifi is a device that able to host a Wifi connection using 3G card.
Small enough to fit in your pocket, but powerful enough to bring the Internet to your whole family wherever your wireless phone goes - no cables required. Just power it on and instantly connect up to five Wi-Fi-enabled devices.
Search for "wifi tethering". There are some apps that turn your phone into a wifi hotspot in android app market, but i have also seen dedicated devices who are essentially wifi+3g modem+battery in one box.
