Currently I've an aircard with 3G network. I use the aircard whenever I'm on the move or out of my office. I'm intending to buy a router so I can connect my aircard to the back of the router's USB port and then have 2-3 laptops connecting to the router.
1) Does that mean I can setup a network anywhere I go even if I were to go to my friend's house who does not even have any internet subscription or modem at all?
2) Can any router on the market do the job as long as they have a USB port behind to plug in my aircard OR do I need a special router to do the job?
3) Is this kind of router called Mobile Broadband Wireless Router or have a special name for it?
Any help will be greatly appreciated. Thank you.
