Next-Generation Modems Speed Performance
Two new standards promise to make dial-up modems faster--but should you buy?
Tom Spring
From the August 2001 issue of PC World magazine
Still surfing the Web with a dial-up modem? You're not alone. Ninety percent of U.S. Web surfers connect at speeds of less than 56 kilobits per second. Fortunately, help is on the way: Two new dial-up modem standards promise faster speeds and new features to improve surfing the old-fashioned way. The first and better known, called V.92, can boost theoretical upload speeds to 48 kbps, up from an average maximum of just 33 kbps with a dial-up modem that works with the current V.90 standard. If you have call waiting on your telephone line, V.92 supposedly will put modem connections on hold to take incoming phone calls. The other newly arrived standard, called V.44, improves compression and promises to make downloading Web pages snappier.A couple of vendors now sell V.92 and V.44 modems. The modems, which cost about $15 more than their V.90 counterparts, are available from both U.S. Robotics and Zoom Telephonics, including the latter's Hayes division. U.S. Robotics modems support only the V.92 standard so far; Zoom sells a modem that supports both new standards. But though the modems are ready, your ISP must support V.92 for advanced features to work--otherwise the modem will operate no better, and possibly worse, than a V.90. Thus far, the big ISPs have been lukewarm toward the new standard. For example, MSN and EarthLink say they are still evaluating V.92. America Online says it's waiting to see if other ISPs support the standard before it commits. Smaller ISPs may be more willing to adopt V.92, notes Nicholas Sten. He is manager of the network solutions group for Option One, which resells Internet access to 130 ISPs in California and elsewhere. "We see it as giving our smaller ISPs an edge over the AOLs of the world," Sten says.
Speed Bumps
A hands-on evaluation of U.S. Robotics and Zoom V.92 modems suggests that the more advanced aspects of the standard aren't completely ready for prime time. When I tested the U.S. Robotics modem, its "modem on hold" feature worked less than half the time. When I tried the same function with Zoom's V.92 modem, an inbound telephone call severed my Net connection without warning. An informal test of the V.44 modem compression standard with Zoom's modem revealed no appreciable speed increases compared with U.S. Robotics V.90 modems. But a "quick connect" feature did cut in half the time that either modem took to log on to a V.92-equipped service provider. Simultaneously, Zoom has begun implementing a feature that maximizes upload speeds to 48 kbps. Both modem makers say that they are still trying to eradicate the bugs in their software and that they will provide upgrades to existing V.92 modem owners as they make improvements. U.S. Robotics also offers free upgrade software for many of its V.90 models. However, most older modems aren't upgradable. Replacing an otherwise satisfactory V.90 modem with a V.92 model is still premature. But if you are shopping for a new modem anyway, buying a V.92 model could turn out to be a wise investment. By fall, network infrastructures will slowly catch up, and your ISP may eventually offer a V.92 line for you to dial in to. If it does, you'll be ready. Quicker Log-ons Can't wait to get online? Give your modem a boost.

Friday,
There's not much we can do to help you increase your connection speed, but we can help you get online faster. Your PC is probably going through an unnecessary rigmarole every time you go online. Here's how to connect faster: Make your modem dial faster. Double-click My Computer, double-click Dial-Up Networking, right-click the icon for the connection you want to speed up, and select Properties. Click the Configure button near the bottom of the dialog box. Click the Connection tab in the next dialog box, then select Advanced. In the Extra Settings box, enter:S11=40 Click three successive OKs to get out of these dialog boxes, and try connecting. If the connection fails, change the 40 to a higher number (say, 45; you might have to choose an even higher number ) and try again. Speed up the log-on process. If you're using your DUN connection solely for collecting e-mail and surfing the Web, and not for connecting to shared devices (those that appear in Network Neighborhood), you can cut the time it takes to connect by following these steps: Double-click My Computer, double-click Dial-Up Networking, right-click the icon for your DUN connection, and select Properties. Click the Server Types tab. Now deselect "Log on to network," IPX/SPX Compatible, and NetBEUI.
Diary of a Free DSL User: Loved Speed,
Ignored Ads From issue of PC
World magazine Suddenly, in the upper right corner of my monitor, a blue jean╜covered butt appeared. No, I wasn't downloading risque photos from the Web. In return for free high-speed Internet access through a DSL phone line, I had agreed to let a company called Winfire run ads on my desktop--and I was getting an eyeful. The New York Times offered to show me its world on the Web. Another advertiser urged me to "make money in minutes!" Others promised links to the friendliest of doctors or the sharkiest of lawyers. A new ad appeared every 15 to 30 seconds. Broadband Internet access is hot. And since Winfire began offering it for free earlier this year, more than a million people have signed up. Many of them will have a long wait. The company started connecting customers in Atlanta and Dallas in April, Los Angeles in May, and New Orleans and Miami in June. Winfire plans to expand its FreeDSL service into 16 other cities, but as of early July only a thousand people actually had the service. Co-CEO Ryan Steelberg's most optimistic prediction calls for no more than 500,000 hookups by the end of the year. A Winfire spokesperson said 95,000 customers have accepted ad-free 56-kbps dial-up service as an alternative while they wait. Not every observer is convinced that Winfire will be able to stay in business, however. Even with ads paying the way, "the cost at this point is too high," says Fritz McCormick of The Yankee Group. Even if you're lucky enough to get to the head of the queue, you'll find a few hidden costs. Users must buy a DSL modem and filters for the phone lines to make them usable for voice service. Winfire will sell you both in a kit that costs $199 up front or about $10 a month for 23 months. Customers must also agree to provide the company with demographic information (used to send targeted ads), and must install software that keeps Winfire's toolbar, with its streaming ads, active on their desktops at all times. Your FreeDSL e-mail goes out with a short text ad at the bottom. Winfire promises not to sell your personal information to others. And in line with most standard DSL contracts, if you want to drop out before 13 months have expired, you incur a $200 cancellation fee. After several tech support calls, I had the inch-high Winfire toolbar (which works with any major browser) docked across the top of my screen. It occasionally obscured a key portion of a game or document, but moving it was easy, if a bit inconvenient. Users say they get used to the flashing ads, which resemble the banners on many Web sites (the toolbar has icons you can use to launch the Web sites of Winfire's business partners). "I'm used to the whole advertising idea. It's not a big deal to me," said Jonathan Poon, 22, a research technician at the Centers for Disease Control. Georgia Tech student Greg Popowitz said the service was slower than the campus network, but it speed up submitting homework from his off-campus apartment. My teenage sons barely noticed the ads--but they did report a marked improvement in download speeds over what our previous 28.8-kbps dial-up connection delivered. In my tests, the bandwidth proved slightly faster than the promised 144 kbps. Want more speed--or fewer ads? Winfire charges just $10 a month for ad-free basic service; $20 a month for 384 kbps; and $35 a month for 1.54 mbps--still slightly less than the $40 most DSL providers charge. If you don't mind a long wait or a constant barrage of ads, consider FreeDSL. Business users, however, may prefer the ad-free service, if only to avoid sudden distractions from the bottom line. Help for the Unwired: Broadband Beamed to You If you're eager for a taste of high-speed Internet access, but don't live within reach of DSL or cable service, help may be on the way. Sprint recently introduced a wireless system that delivers broadband access at up to 256 kbps upstream and between 1 and 5 mbps downstream by bouncing signals between diamond-shaped antennas perched on users' rooftops and a larger antenna on a nearby mountain. Called Sprint Broadband Direct, the service was in trials in the greater Phoenix area for more than a year before launching formally this spring. Home customers pay $40 a month and get a single IP address; business users pay $90 for five IP addresses and faster callbacks when they need tech support. Installation costs $299, with special price breaks to customers who sign long-term contracts. By year's end, Sprint plans to expand the service to 12 to 15 new markets, including San Francisco and Houston. The service uses 13.5-inch-square rooftop antennas that connect to a coaxial cable the installers run through a wall (in a setup similar to cable TV installations) and then connect to a modem attached to the user's PC. Radio signals broadcast from the rooftop antenna can travel up to 35 miles, Sprint says. Receiving and broadcast antennas must stand in line of sight, so in areas with hills and tall buildings Sprint uses multiple transmitting towers. The system should appeal to anyone who can't get cable or DSL service, just as satellite TV dish antennas found early buyers in areas without cable. Early customers in Phoenix are enthusiastic. J. R. Robertson, chief executive of Air Photo USA, says Sprint's service speeds up his company's Web sales of digitized aerial photographs. Shari Leyva, whose home-based business sells promotional products, appreciates how the system lets her place orders online without tying up her phone. "You're always online," she says. "There's no dial-in and no waiting. All you do is hit a button, and you're on the Web." |
