Lately, I’ve found attempting to do web development on a local environment without Internet access while travelling just doesn’t cut it anymore. This is especially true for long roadtrips. Rather than dealing with tethering or a mobile hotspot, I decided to spring for a Netgear AirCard 340u. For GSM networks in the US, it happens to be the best USB wireless broadband modem currently available. It supports everything from GPRS through LTE on what appears to be most of the bands AT&T and T-Mobile currently use (a true rarity, though I can not confirm support of LTE on band 2 (1900MHz PCS), I do get T-Mobile LTE in the Twin Cities).
