When Adele Rothman bought her 16-year-old son a car in 2003, she made sure to pick one that had OnStar, the onboard communications and safety system.

What the Scarsdale, New York, resident didn't know was that the OnStar system in the car was already doomed to die. The federal government decided in 2002 to let cellular carriers shut down analog cell phone networks, used by Rothman's Saab and about 500,000 other OnStar-equipped cars, after February 18, 2008.

It's the end of the nationwide network that launched the U.S. wireless industry 24 years ago, and it leaves a surprising number of users like Adele Rothman in the lurch.

OnStar told Rothman in March its service would stop at the end of this year, in anticipation of the network shutdown in February. "I was really upset," she said, "because that was my tieline" to her son.

Perhaps a million cell phones will lose service, but those are cheap and easy to replace. The effects will be felt the most by people who have things that aren't phones but have built-in wireless capabilities, like OnStar cars and home alarm systems.

The shutdown date has been known years in advance, but some industries appear to have a had a problem updating their technologies and informing their customers in advance, which raises the question of whether the effects will be even more widespread the next time a network is turned off, given the proliferation of wireless technology.

General Motors Corp., which owns OnStar, started modifying its cars after the 2002 decision by the Federal Communications Commission to let the network die, but some cars made as late as 2005 can't use digital networks for OnStar, nor can they be upgraded. For some cars made in the intervening years, GM provides digital upgrades for $15.

In 2006, OnStar said it had let customers know of the shutdown with a posting on its Web site. This year, it said it had notified all affected customers. Spokeswoman Cristi Chojnacki said she was unable to comment beyond those statements. General Motors and other car manufacturers with similar systems, including Daimler AG's Mercedes-Benz, are facing a potential class-action lawsuit over the analog shutdown.

When Rothman complained, GM sent a $500 coupon toward the purchase of a new car. To compensate for the lack of OnStar, she outfitted her son's car with a handsfree system and a Global Positioning System.

A week before the end-of-year shutdown, the analog coverage map is still the first one presented on OnStar's Web site. The digital coverage map, showing large areas of "limited" service in out-of-the-way places, is available on another page.

On the home alarm side, about 400,000 systems still use analog service, according to Lou Fiore, chairman of the Alarm Industry Communications Committee. In most of those systems, the wireless link to the alarm center is a backup to the landline. But some homes lack a landline, so the wireless link is the only connection to the outside world.

Verizon Wireless, AT&T Inc. and Alltel Corp. are the largest carriers that still have analog networks. Alltel will take more time than Verizon and AT&T to close its network, shutting down in three stages ending in September. Each carrier will keep its portion of the newly available spectrum, and will use it to boost their digital services.

A few rural cellular providers may keep their networks up. Plateau Wireless, which provides service in eastern New Mexico and western Texas, will maintain its analog network alongside a digital one "for the foreseeable future," according to Chief Executive Tom Phelps.

Many of the company's 75,000 customers are farmers and ranchers, and the network's superior range helps them because it fills gaps in the digital network. The larger carriers say their digital buildout will cover any gaps left by the demise of analog service.

I read the same article in today's paper and, first off, it came as quite a surprise! I've certainly heard about the migration of television broadcasts to being fully digital, but I can't say I've heard anything about this before!!!

Also, I find the whole OnStar issue rather ridiculous. Especially for such late-model cars and the possible lack of upgrade options.

Not to mention the limited coverage in out-of-the-way places that also applies to all cell phone carriers. I know when I go up to remote areas of Michigan, such as up North or out in the deep woods, I sometimes fall back to only analog service and am now concerned what will happen after February.

I heard about that sometime within the last year or so. Hopefully they will be able to boost the digital service, as they claim. If that's true, then good riddance to analog.

What's the deal with this OnStar, anyways? I haven't really used it myself. It seems to me that if you have a cell phone and a GPS unit, then you're good to go.

I've never used Onstar either but from what I understand the newer system can detect air bag deployement as well as rollover and other issues involved in an accident plus they can direct Emergency Response Units directly to your location. About the only plus I see outside of a GPS and cell phone.

I too have run into problems while driving out in the country or up to Michigan were the only signal I get is analog (currently with Sprint). Hopefully they're will be more digital coverage in the areas currently only served with analog.

Didn't know Alltel was analog, have to let my Stepdad know as both he and my mom use their system.

Alltel has both digital and analog, just like the others. Their only difference is that they're going to be a little slower at closing their analog system. The only people who will have problems are the ones with really old cell phones that don't support digital.
