if you are lookin for internet on the move why don't you ask your local broadband or internet service providers for wi fi connection or a wi max connection depending on where u live becoz it depends where they have their annttenas they give u a simple card which u put into ur pcmci slot or if ur computer is wi fi enabled u hardly need any device to connect it to the net but its more expensive than normal broadband connections so u better compare the costs before investing....
for more details on wifi click on this linkhttp://en.wikipedia.org/wiki/Wi_fi
and for wi max the link ishttp://en.wikipedia.org/wiki/Wi-max
wi max is faster than wi fi but also costlier also wikipedia is a very helpful an informative site check it up for any doubts u have in any field!!
hope this helps u!!
