There are a few ways to get mobile broadband access on a portable computer. You can pick up a laptop, tablet, or other device with an integrated 3G modem. You can purchase a 3G or 4G USB stick that you can plug into your computer to connect to a network. Or you can get a portable WiFi hotspot like a MiFi that lets you connect multiple devices to a mobile broadband network.
Now it looks like there’s a new option… sort of. Connect One has unveiled a device called the Wi-Reach Classic. Basically it’s a portable WiFi hotspot that’s designed to work with any 3G USB modem. Just insert your modem in the USB port and the $99 Wi-Reach classic will let you share your connection over WiFi. Up to 10 computers at a time can connect to the hot spot (although I suspect you’ll take a serious speed hit if you try to hook up more than 2 or 3 computers).
You can also download software that adds support for 4G WiMax and LTE networks. Connect One says the mobile hotspot should get about 5 hours of battery life.
