Buried inside many of the latest smartphones is a capability that few people take advantage of. A feature called tethering lets a phone go beyond talk, email and Web surfing to act as a mobile hotspot that can supply Web access to nearby computers, tablets and other devices. "It lets [smartphone users] always have the Web with them without taking any extra equipment along," says Allen Nogee, research director for wireless technology at market intelligence firm In-Stat.
Like dedicated mobile hotspot devices, these phones connect to a mobile data network and then act as a Wi-Fi router, distributing the bandwidth to nearby clients. There is a price to pay for the convenience that hotspot phones provide: Three of the four national networks charge an additional fee to use tethering. On the other hand, you don't have to worry about finding a public Wi-Fi hotspot or having another device to buy, lug around, keep charged and accidentally leave behind.
Want to know more? After speaking to analysts, network engineers and other mobile experts, I've rounded up and answered the 12 most common questions about smartphone tethering, including options and carrier policies. Additionally, I used a couple of smartphones as hotspots in various parts of the U.S. and Europe to discover what the experience is like in real life.
Finally, I've gathered a listing of all the hotspot-capable smartphones currently available from the Big Four U.S. carriers, including how much they cost, which network(s) they work on and how much tethering services cost.
