Today, many smartphones including iPhone and Android devices can legally be used as mobile hotspots. Look at your phone's manual to see if it has the capability to provide WiFi access to your laptop and other devices. For smartphones that don't come with the wireless hotspot feature, apps like MyWi try to fill in the gaps. Be careful with these; they generally require that you jailbreak your phone, and data charges can be costly.
Another great way to stay connected when you are away from a standard wireless network is to use WiMAX devices. Companies like Clear, Sprint, Comcast and others now offer hardware that will enable you to take your broadband Internet service with you wherever you go. These devices usually take the form of small hubs for wirelessly powering multiple devices or USB modems, designed to power a single device to which they are connected.
Mobile hotspots and WiMAX devices definitely provide Internet on the go, but coverage areas vary. If you plan to camp in a remote location, you may need to find a way to boost your WiFi signal.
