FOR YEARS AMERICANS WHO accessed the Internet via cellphone networks looked across the ocean to Europe with envy. The speed of American cellphone networks badly trailed those in Europe.
But not anymore. Gradually, and with relatively little fanfare, Verizon Wireless has deployed a nationwide cellular data network in the United States that blows away the fastest widely deployed networks in Europe, the so-called 3G networks that have been rolled out there to huge publicity. And Sprint is starting its own rollout of a similar speedy network based on the same technology Verizon uses.
That technology is called EV-DO, for Evolution-Data Only, or Evolution-Data Optimized. It is the first wireless technology deployed over a wide area that matches the speed of home broadband — at least the slower reaches of that wired service. Unlike the most common form of wireless broadband, Wi-Fi, the new EV-DO service doesn't rely on hot spots. It's available all over a metro area, wherever there is cellphone service — even in a moving car.
Verizon has been rolling out the new service, city by city, over the past year or so, and it is now available in 61 major metropolitan areas and 65 airports across the country, according to the company. Because it's based on a technology called CDMA, developed by the U.S. company Qualcomm and not widely used in Europe, EV-DO has given the U.S. an edge, even if only for a while.
You can get the service in two ways. First, you can buy a data-enabled smart phone, like the $600 Samsung SCH-i730, which can handle email, instant messaging and Web access over EV-DO. Or you can buy a wireless EV-DO modem card for your laptop, like the $170 Kyocera KPC650, which allows all your Internet-oriented PC software to access the Web via EV-DO.
There are also different rates. Verizon has been charging $80 a month for an unlimited EV-DO data plan. But recently, it cut that price to $50 a month for people who already have a Verizon voice calling plan.
For those with mainstream phones that are mainly designed for voice calling but are EV-DO capable, Verizon offers a $15-a-month plan that mostly covers viewing short video clips on an EV-DO service called V Cast, but also offers unlimited, albeit much clumsier, Internet access.
How fast is EV-DO? Verizon is predicting average speeds of between 400 and 700 kilobits per second. That's up to 10 times its previous fastest data speed, on an older network called 1X. In my tests, Verizon's promise proved realistic, and I often topped 700 kbps.
To put those speeds in perspective, many wired DSL plans in American homes operate at speeds of 700 kbps or less, so EV-DO is in the same ballpark.
There are faster wired broadband connections available, from both DSL and cable modem providers. Many homes with cable modems have service that runs at 3 megabits a second, or four times faster than EV-DO. And some Wi-Fi hot spots may operate at faster speeds as well, though that depends a lot on how they are set up. But EV-DO is clearly a broadband service, at least by the American definition of the word "broadband." (In Asia, they laugh at our definition. They think of broadband as being 20 to 50 megabits per second.)
