Wi-Fi on Wheels Is Steady, but Has a Speed Bump

Walter S. Mossberg — Thu, 13 Nov 2008 02:04:05 +0000

Wi-Fi wireless Internet connectivity has become nearly ubiquitous. Whether you’re at home, in a coffee shop, or even on some commercial airliners, you can get online with a Wi-Fi-equipped laptop, smart phone or portable game machine.

Now, Wi-Fi is making its way into your car. A small California company, Autonet Mobile, has teamed up with Chrysler and others to sell a service that floods any brand or model of car or truck with Wi-Fi Internet connectivity that can be used by multiple passengers and devices simultaneously. It’s a dealer-installed option on Chrysler vehicles, but Chrysler dealers, and some independent auto electronic shops, will install it on any brand of car for a fee.

The system works via a special wireless router, mounted in the trunk or rear cargo area, that draws Internet connectivity from cellphone towers and then converts it into an in-car Wi-Fi signal with a range of 100 feet. This router looks like a military device, because it is ruggedized to survive jolts and vibrations, and is shielded to avoid interference with the car’s electronics or with cellphone calls.

As long as they have built-in Wi-Fi, the laptops and smart phones used in the car don’t need any add-on hardware or software to use Autonet. To them, it looks like any other Wi-Fi signal. And no special car antenna is needed; the router uses its own large antennas.

I’ve been testing Autonet Mobile in a rented Saturn Vue SUV in Washington, D.C., and its suburbs, and found it worked well for most basic Internet tasks like email and Web surfing. The router turns on when the car does, and the Wi-Fi signal shows up about 30 seconds later. However, Autonet is relatively pokey. It’s too slow to be reliable for streaming video longer than brief YouTube clips, or for smooth video chatting.

Perhaps the biggest downside of in-car Wi-Fi is that it provides one more potential distraction for drivers. The company says the service is only for passengers, not drivers, but there’s no technical barrier to a driver using it.

Of course, drivers already can court danger this way by using cellphone wireless connectivity on a laptop, iPhone, BlackBerry or other connected device. And that raises another question: Since you can already connect to the Internet from a car with a smart phone or a cellular data card for a laptop, why would you want Autonet?

There are three reasons. First, cellular Internet access is typically tied to a single device at a time. But Autonet’s Wi-Fi service works just like Wi-Fi in your house: Multiple people with multiple devices can use it at the same time. In fact, the company envisions that the service’s primary use will be to allow children in the back seat to use laptops for social networking, online games or homework; and multiple adult passengers to conduct online business or research routes and destinations.

Second, the monthly fees can be lower, at least for laptops. A typical cellular data card for a single laptop costs $60 a month. But Autonet’s service starts at $29 a month for the entire car, regardless of how many devices are being used. A premium plan costs $59. The plans differ by how much data you are allowed to consume monthly. And Autonet requires no special laptop cards or software.

Lastly, the company claims that it has invented a technology that keeps the connection steadier while moving than the typical direct cellular connection. Although some videos froze on me, I never lost Autonet’s Internet connection, whether moving slowly through downtown D.C. or moving faster on suburban highways and streets.

In my tests, with a laptop and an iPhone, Autonet’s speeds ranged from around 100 kilobits per second to around 500 kbps — far slower than a typical cable Internet service in a home. My average speed was between 400 kbps and 450 kbps.

There are some other drawbacks. First, the router costs $499, though that will soon drop to $399 in a holiday price promotion. Second, you have to sign at least a one-year contract, even if you pay monthly. Third, your Internet usage is limited. The $29 plan gets you just 1 gigabyte of data a month, while the $59 plan gets you 5 gigabytes. That should be plenty for most typical users, but not for those with large appetites for data.

These service fees are all-inclusive. You don’t have to pay anything to any cellphone carrier. But there is also a $35 “activation fee,” whose justification is murky, and installation costs are estimated at $50 to $75.

For security, you can set Autonet up with a password, but it doesn’t yet use the most advanced version of Wi-Fi security. The company says that, while it can track and manage your Internet connection, it cannot determine the content of what you are doing online.

Finally, because the router is hard-mounted, you can’t remove it for use in, say, a hotel room or second car.

If you’re willing to invest in the router and can tolerate the slow speeds, Autonet might be what you want — as long as you can resist using it while driving.

Dell Remote Access Keeps Your Files at Your Disposal

Walter S. Mossberg — Thu, 09 Oct 2008 01:06:02 +0000

Say you’re on the road and you need to look at a file that’s on your main computer back at your office or house. Or say you’re using a device with limited storage, like a smart phone or one of the tiny new “netbook” portable PCs, and you want access to a file that isn’t on the device at hand.

You might be able to get at the desired file if you have previously uploaded it to an online storage or photo-sharing service, or emailed it to yourself. But, in many cases, you could be stuck.

[ See post to watch video ]

Now Dell (DELL), the big computer maker, is aiming to solve that problem with a new service called Dell Remote Access. Despite the name, the service can be installed on any brand of Windows PC running Windows XP or Windows Vista to make its files remotely accessible, as long as it has a broadband connection. You can transfer, or stream, or share these files with others. You can even remotely use the host computer’s Web camera.

And some of the service’s functions also work even if your remote device is one of Apple’s (AAPL) Macintosh computers or iPhones, or a computer powered by the Linux operating system, like Dell’s own Mini netbook.

For basic functionality — making the files on one Windows PC remotely accessible from other devices — Dell Remote Access is free. If you want to use its advanced functions, like the ability to remotely control the host PC or to access other devices on your home network, it costs $9.95 a month, or $99 a year. This paid version of the service also includes the ability to share with others access to files or to devices on your network, such as stand-alone Web cameras.

You only need to install special software on the host PC whose files are to be remotely accessed. For basic file access, the remote devices require just a Web browser and a password to tap into the host computer. You can download the software, and get started with the service, at dellremoteaccess.com.

I’ve been testing Dell Remote Access for a few days, at home and on the road, and found that it works well, despite a few glitches and limitations. It’s not revolutionary — many other services and software programs do part or all of what it does, with varying degrees of technical difficulty and at varying fees — but Dell Remote Access combines a wide variety of functions into a fairly simple package. It will be available as a preinstalled option on Dell’s PCs later this year.

Dell also is hoping it will give a boost to sales of its Mini line of very small machines with limited internal storage for files.

For my tests, I installed Dell Remote Access on my home Dell desktop, an XPS One model running Windows Vista. The installation was easy and quick, except for one oddity: To use the new service, you have to uninstall a network diagnostic utility Dell installs on its machines, called Dell Network Assistant. Since I had little or no use for the utility, this was no big loss, but if you rely on it, this conflict could pose a problem.

Next, I used the Remote Access software to select folders I wanted to make remotely accessible. By default, the program assumes you want to share your documents, music and pictures folders, but I added some others. The software tests your network connection to let you know how well it’s likely to work.

I used a variety of remote devices to access this home Dell. These included a Sony (SNE) Vaio laptop running Vista, a Mac laptop and an Apple iPhone. I even tried accessing the Dell machine from a virtual Windows XP installation running on the Mac.

Some of these tests were conducted from within my home network and others were conducted from across the country.

In general, the tests went well. With the Sony laptop, and within Windows XP running on the Mac, I was able to view photos and slide shows, and stream music and videos, from the Dell in all locations. I opened Microsoft Office (MSFT) files and PDF files remotely and transferred files to the remote machines. I was even able to remotely control the Dell at decent speeds and use the Dell’s built-in camera.

The only annoyance was that every time you want to remotely control the host machine, you must download and install a small utility. You also have to leave on your home computer.

Dell’s system provides more limited functionality if your remote machine is a Mac using Apple’s operating system, or a Linux machine or a mobile phone. With these setups, you can only view, stream or transfer files only from the main host computer. You can’t do remote control or view cameras.

But these limited functions did work pretty well on the Mac and the iPhone, although in some cases I had to first download a song to the Mac before it would play, rather than simply streaming it directly from the Dell.

But Microsoft Word documents stored on the Dell opened right up on the Mac. It was particularly impressive to be able to view a document or photo stored on the Dell from an iPhone thousands of miles away.

Dell Remote Access is a worthy service that’s worth a try.
