You can use MiFi which is a wireless router which can work for devices with certain distance lengths. There are other two methods you can use to get internet connection while on travel. You can be in a range of a public none secured wireless connection like a hotel who offer Wi-Fi services. The other option is to get service from AT&T or Verizon as they have items which can create hotspots with the air card service while on travel. This would require you to make payments so as to get the service and you can get more information at http://en.wikipedia.org/wiki/MiFi.
