Ford cars are about to become true mobile hot spots.

The carmaker announced Monday the next generation of its Sync system designed to let Ford owners plug a USB modem directly into a car's built-in Wi-Fi, creating broadband Internet access to all passengers. Those in the car can jump online through any Wi-Fi-enabled device, from smartphone to laptop.

Ford said that this factory-installed capability will be available next year on certain Sync-equipped cars and that no extra hardware or subscriptions will be needed outside of an existing broadband modem, which the customer supplies. Ford's Wi-Fi system will include WPA2 security, ensuring that only people in the car will be able to hop onto the network.

"The speeds with which technology is evolving, particularly on the wireless front, makes obsolescence a real problem," Doug VanDagens, director of Ford's Connected Services Solutions Organization, said in a statement. "We've solved that problem by making Sync work with just about any technology you plug into it. By leveraging a user's existing hardware, which can be upgraded independent of Sync, we've helped ensure 'forward compatibility' with whatever connectivity technology comes next."

Design by Ford and Microsoft, Ford's Sync lets drivers make calls, play music, get directions, grab news and weather, and search for businesses and other information, all using voice and text-to-speech technology. Ford's new Sync edition won't be the first Wi-Fi technology to give people on-the-road Internet. Similar devices have popped up over the past year, some dealer-installed and some independent.

Autonet Mobile designs similar hardware for cars, as does a company called Waav. Autonet does require a subscription fee for its service--$29 a month for 1GB of data or $59 a month for 5GB. But it's an independent device designed to work with different makes and models (though currently available as dealer-installed for Cadillac), while Ford's Sync only comes with certain Ford vehicles.

A new version of Bluetooth has been revealed by the industry group behind the wireless technology, which is targeting low-energy applications in the health care, fitness, and security markets.

The Bluetooth Special Interest Group announced the adoption of Bluetooth Core Specification version 4.0 on Thursday. The new iteration follows the speed-centric version 3.0 of the Bluetooth specification by just 10 months, but the two versions are intended for different use cases.

"With today's announcement, the race is on for product designers to be the first to market," Bluetooth SIG chief Michael Foley said in a statement. "Bluetooth low-energy modules for all sorts of new products may now be qualified--this is an important step towards our goal of enabling new markets with Bluetooth wireless technology."

As we move toward 2010, there is little question that mobile devices and smartphones will continue to have a huge impact on the market. Research firm Nielsen predicts that smartphones will dominate market share by the end of 2011, with the iPhone and Android-based phones taking the lead spots by a wide margin over traditional cell phones.

As devices mature, Wi-Fi connections become more ubiquitous, and 3G networks become more reliable, consumers will start looking for new ways to use their smartphones as replacements for other larger devices, such as PCs and TVs. One area that has been called out for growth is mobile video and TV, as well as streaming movies directly to a mobile device.

mSpot CEO and co-founder Daren Tsui made the case to me recently that full-length streaming movies will be important to consumers in 2010 because people want entertainment on the go and on demand. Research suggests that the adoption curve will be lead by young males 18- to 24-years-old and parents with young children looking to keep kids distracted.

Not surprisingly, mobile carriers are very supportive of mobile movies. According to Tsui, mSpot has been powering mobile movies on the Sprint wireless network for three years and is currently working with other carriers to bring the service to their user base. Realistically, carriers will always be happy about services they can offer and charge for, but the real question is if they could handle an influx of users sucking down huge amounts of bandwidth.

The obvious obstacle to be overcome is the strength of the data network. Streaming full-length movies to a phone is data-intensive, and therefore relies heavily on a strong, consistently reliable network. Assuming WiFi is available, this is a non-issue, but, as an example, AT&T's 3G network has struggled with the data usage of iPhone users and you can just imagine what will happen when millions of people start streaming movies.

Anecdotally, I can tell you that my wife and I bring an iPod Touch out with us to entertain my 2.5-year-old with various games and movies. Pocket-size mobile devices, iPod or otherwise, can be great learning tools as well as distractions when things are going sideways or when you just want to go to a restaurant and not chase a kid around. That said, my iPhone/AT&T network experience has been so spotty that I would likely opt to keep the content local, though in an ideal world new content could be downloaded in the background.

Assuming bandwidth is not an issue there are many possibilities for mobile content to take the place of traditional PCs or print media but in the near term mobile content will be only as good as its data connection.

Google said Tuesday it will subsidize free wireless network access in 47 airports from now until January 15--and indefinitely in the airports of Burbank, Calif., and Seattle.

The promotion, in cooperation with Boingo Wireless, Advanced Wireless Group, and Airport Marketing Income, is the latest effort to use free Wi-Fi to boost a brand. Among others: Yahoo is sponsoring Wi-Fi in Times Square in New York, and Google is sponsoring Internet access on Virgin America flights during the holidays.

Among the larger participating airports are those in Houston, Boston, Miami, Las Vegas, Nashville, San Diego, Baltimore, and St. Louis. A full list of the airports is at Google's free holiday Wi-Fi site.

The move, though not cheap, is probably smart. Plenty of business travelers have a laptop and time to kill, and today's consumers are increasingly likely to be equipped with laptops, iPod Touches, or other devices that can use wireless Internet access. Google is spending some money for an opportunity to give a lot of people the warm fuzzies when they encounter the Google brand.

And in the big picture, Google gets to show people what the world might be like if there were more high-speed wireless Internet access--something the company has been aggressively lobbying for in Washington, D.C. Many people are used to wireless networking in their homes, but it's a different matter on the road.

There are downsides, though, too. Having been to dozens of conferences where the wireless Net access collapses as soon as the keynote speech begins, I'm acutely aware that providing large-scale wireless Internet access is technically demanding--and people get unhappy when a promised benefit evaporates. And public, anonymous places such as airports and urban population centers are great spots for hackers to launch main-in-the-middle attacks by offering "Free Wi-Fi," so exercise caution when logging on to these networks.

As Apple and Research In Motion have won a greater share in the Wi-Fi handset market over the past year, Nokia has lost share.

Though Nokia is still the leading vendor for dual-mode smartphones (Wi-Fi and cellular), its market share dropped to 35 percent in the second quarter, compared with 50 percent in the same period a year ago, according to a report released Monday from In-Stat.

The report "Wi-Fi in Mobile Phones: Dual Mode Becomes the In Thing" tracked the major Wi-Fi phone vendors, including Nokia, Apple, Research In Motion, HTC, and Samsung. Among those, Apple has enjoyed the greatest growth in market share, from 3 percent in the second quarter of 2008 to 20 percent in this year's second quarter.

Market share for both RIM and Samsung has also weakened the past few quarters, though less so than Nokia's. RIM's 15.7 percent chunk of the market for the second quarter of the year was down from its first-quarter high of 17.6 percent. Samsung's share has been relatively flat but usually dips a bit from the first to the second quarter, notes In-Stat.

In sheer unit volume, Nokia has done well the past few quarters, with 9.3 million Wi-Fi handsets shipped in the second quarter of the year compared with Apple's 5.2 million shipments. However, Nokia's shipments have dropped since the first quarter of 2008 when it saw 12 million units fly out the door. Over the same period, Apple, RIM, and HTC have seen their shipments grow.

As the No. 2 Wi-Fi handset vendor, Apple has also outsold third-place RIM in dual-mode phone shipments, says In-Stat. Though RIM still has a larger market presence, not all of its Blackberry devices include Wi-Fi. HTC and Samsung rounded out In-Stat's list as the fourth and fifth top Wi-Fi handset vendors, respectively.

The report also detailed the growth of the Wi-Fi smartphone market overall. The industry shipped 37 million handsets in 2007, and 103 million units in 2008. That rise is because of several factors, notes In-Stat, including greater functionality, lower prices, and carrier promotions. Initially targeted to the business market, smartphones are also now an entrenched hit with consumers, which In-Stat attributes to the success of the iPhone.

Wi-Fi handset shipments are expected to rise just 25 percent to 128.4 million units for 2009. That compares with a nearly 180 percent jump in 2008.

But In-Stat sees gains ahead. By 2010, the growth rate is likely to climb to 43 percent. Though that rate may not be sustainable, it should remain strong in the coming years. Wi-Fi will also become more prevalent in mobile phones. This year, 11.5 percent of handsets include Wi-Fi; by 2012, that figure will grow to 25 percent, predicts In-Stat.

To compile the report, In-Stat relied on its own data as well as interviews with Wi-Fi equipment vendors.

Travelers flying on Virgin America over the holidays will get free in-flight Wi-Fi thanks to Google, the companies said Monday.

Google and Virgin America are teaming up to offer free Wi-Fi Internet service for all Virgin America passengers traveling between November 10, 2009, and January 15, 2010.

The Gogo Wi-Fi service, which was rolled out to Virgin America's entire fleet of planes in May, is normally available for $12.95 for flights of over three hours. It's $9.95 for flights between one and a half hours and three hours. Flights of less than an hour and a half are $5.95. There's a special deal for people using smartphones and other Wi-Fi enabled handhelds that costs $7.95 for flights over one and a half hours.

Virgin America estimates that between 12 percent and 15 percent of its customers are using the Gogo Wi-Fi service. On some of its cross-country flights, between 20 percent and 25 percent of its passengers are using the service.

"Since the launch of Wi-Fi on all of our planes, we've seen an overwhelmingly positive response from travelers," Porter Gale, vice president of marketing at Virgin America, said in a statement.

Virgin America hopes that offering the Wi-Fi service will help it win more customers. In a recent survey the airline conducted it found that more than half the respondents said that Wi-Fi would influence their choice of airline. Google and Virgin America are calling the free Wi-Fi promotion a gift to their customers. But for Virgin America it is also a way to give customers a taste of the inflight Wi-Fi service, which will hopefully whet their appetite for Internet service on future Virgin America flights.

A new Wi-Fi specification will let wireless devices discover and connect to one another without a router.

The spec, called Wi-Fi Direct, was announced Wednesday by the Wi-Fi Alliance, the industry group that promotes the technology. By making it much easier for devices to connect directly to each other using Wi-Fi, the new spec could pose a challenge to wireless technologies such Bluetooth.

The way Wi-Fi Direct works is that it allows Wi-Fi-enabled devices such as phones, cameras, printers, computers, keyboards, and headphones to connect to other Wi-Fi devices individually or to multiple devices at once. The spec will support standard Wi-Fi data rates, and devices will be able to connect to one another within about 100 meters of each other. This would allow just about any device that has Wi-Fi built into it to use wireless broadband instead of Bluetooth. It could even eliminate the need for Wi-Fi routers in some places.

The new spec will turn gadgets into mini Wi-Fi access points, which means that it could reduce the need for home Wi-Fi routers. It could also hurt Bluetooth, which is widely used to provide similar peer-to-peer connections between devices. For example, Bluetooth technology connects headsets to music players and cell phones. And it's used to provide other high-speed wireless connections over short distances between other devices. The new Wi-Fi Direct specification would offer the same function.

Ad hoc wireless connections are already supported via the current Wi-Fi standard. But the Wi-Fi Direct specification would make it easier for devices to discover each other and connect. The Wi-Fi Alliance plans to publish the new peer-to-peer Wi-Fi specification soon and says it will begin certifying devices for Wi-Fi Direct in 2010.

Following the finalization of the Wireless-N (802.11n) standard, the Wi-Fi Alliance, a nonprofit group that tests and certifies wireless products to ensure they interoperate, launched on Tuesday its new test program that supports the final specs of the standard.

This certification is still necessary because, according to Kelly Davis-Felner, marketing director of the Wi-Fi Alliance, the final specs include a lot of options and items that vendors could interpret differently, which could lead to products that don't work with each other. "Our certification program ensures that the product conforms with the final standard and interoperates with others." Felner added.

The new certification program is basically the same as the one used for the Draft N 2.0, with the addition of a few tests for new optional features, including:

• Test support for simultaneous transmission of up to three spatial streams
• Packet aggregation (A-MPDU), to make data transfers more efficient
• Space-time block coding (STBC), a multiple-antenna encoding technique to improve reliability in some environments
• Channel coexistence measures for "good neighbor" behavior when using 40 MHz operation in the 2.4 GHz band

Davis-Felner also confirmed that all existing Wi-Fi Certified Draft N products will interoperate with the new Wi-Fi Certified N products. The reason for this is because the final standard only adds more options on top of the specs supported by the Draft N 2.0 without any major changes.

This also means most of the existing Draft N products can be upgraded to receive the final specs via firmware. However, once upgraded, they will need to be tested again to be certified with the final N specs.

Currently, there's not yet any Wi-Fi Certified N products on the market but there are a few vendors that have submitted their hardware to be to be used in the interoperability test bed, and their devices will be the first to become Wi-Fi Certified N products with the new testing program. These devices include:

• Atheros XSPAN Dual-band 2.4/5GHz PCIe MiniCard for Computing Designs, Full MIMO Configuration
• Atheros XSPAN Dual-band, Dual-concurrent 2.4/5GHz, Gigabit Reference
Platform for AP/Routers, Full MIMO configuration
• Broadcom Intensifi Dual-Band 802.11n Client Reference Design
• Broadcom Intensifi XLR Dual-Band 802.11n Router Reference Design
• Intel Ultimate N WiFi Link 5300
• Marvell Smart Wi-Fi 802.11n 3x3 450 Mbps Dual-Band Access Point
• Ralink 3x3 AP

It's unclear when any of these will be available but you can expect to buy some by the end of the year.

Finally, the Draft will now be taken off this logo.

As predicted last month, the IEEE has finally approved the 802.11n high-throughput wireless LAN standard.

Finalization of the new wireless networking standard--which is capable of delivering throughput speeds up to 300 megabits per second (and even higher)--took exactly seven years from the day it was conceived, or six years from the first draft version. The standard has been through a dozen or so draft versions.

News of the ratification broke via a blog post displaying an e-mail sent by Bruce Kraemer, longtime chairman of the 802.11n Task Group, to task group members. There has been no public announcement yet. Update 5:49 p.m. PDT: A press release has been issued.

(The 802.11n Task Group is part of the 802.11 Working Group, which oversees WLAN (wireless local-area network) standards. Task group members include the majority of Wi-Fi chipmakers, software developers, and equipment OEM vendors. Meru Networks, one of the members, posted the blog that broke the news.)

It's likely, however, that final approval of the standard will be publicly announced by September 15, the date when Meru Networks puts on a public Webcast to provide answers about the ratification.

According to the Wi-Fi Alliance, the group that tests and certifies wireless products to ensure their interoperability, all existing Wi-Fi Certified Draft N wireless products will still work with the final standard.

802.11n offers much higher speeds than the previous, already-ratified 802.11g, which caps at only 54Mbps. Due to the compelling higher speed, most wireless vendors haven been offering 802.11n-based (also known as Wireless-N) products during the past six years and calling them Draft N products. Now the Draft is no more.

According to the Wi-Fi Alliance, most, if not all, of the existing equipment can be upgraded to the final specification via a firmware update. Finally, all future wireless networking products will be compatible with today's products that have been Wi-Fi-certified.
