Vending future? Heat raises soda price
Wireless technology spurs innovations

SAN DIEGO (AP) -- How strange. The price of sodas in that amusement park
vending machine rises with the temperature. In the blazing midday sun,
they cost double what the machine demands on a cool cloudy evening.

While such radio-controlled price manipulation may just be hypothetical,
the technology isn't.

As wireless data networks spread the Internet, previously dumb machines
are being connected and endowed with intelligence while portable
communications devices are getting smarter.

Proponents haven't yet agreed on an adjective for the dawning new era in
computing: Pervasive. Ubiquitous. Continuous. Persistent.

It's a piece down the road, this unwired world. Three to five years is the
consensus among industry analysts. The telecom meltdown still acts as a
ball-and-chain on new investment.

But there's no shortage of good ideas percolating -- the soda machine
scenario was one, posited by an IBM executive.

Industry insiders and invited journalists sampled some of the ideas at
IDG's fourth DEMOmobile show in San Diego, getting a gander at prototypes
and finished products.

'Badge' operates on voice commands
Notable among them was the Vocera Communications System, which bundles the
functionality of a walkie-talkie, phone and pager into a 1.6-ounce "badge"
that users wear around their necks and operate hands free with voice
commands.

It's designed for hospitals, retail stores, assembly lines _ anywhere
mobile workers need steady contact.

Vocera's clever software uses voice recognition and transmits
conversations in data packets using WiFi, the increasingly popular
short-range wireless standard.

Vocera officials believe the product, hitting the market in October, will
give harried nurses and internists a better way to keep in contact,
especially during crises.

"What they have essentially today is overhead paging and running down the
hall yelling," said Brent Lang, vice president of marketing at the
44-person Cupertino, Calif., startup.

Excellent WiFi alternatives
Far less spectacular but pregnant with significance was Microsoft Corp.'s
introduction of WiFi hardware.

Excellent alternatives from companies including Linksys and Netgear have
been on the market for some two years. But Microsoft is apt to make
inroads with software and a setup routine that look to be idiot-proof.

Sales of such WiFi equipment -- which extends the Internet and other
networks some 300 feet per hub -- are on pace to grow 73 percent this
year, according to the analyst firm Dataquest.

Compare that to the 10 percent growth that analyst Mark Lowenstein of
Mobile Ecosystem sees in the cellular market, and it's easy to understand
the excitement around WiFi.

Lowenstein believes "an aligning of the constellations" that includes the
mating of various types of communications standards is next in the
wireless industry's evolution.

One company working to spur that vision is Idetic Inc. of Berkeley, Calif.

Idetic's technologies aim to provide seamless roaming between cellular,
WiFi and other networks. A new product that Idetic announced lets you
watch television on the latest cell phones.

With the maturing U.S. wireless market awash in some 100 million cell
phones, startups have found clever ways to help corporations reduce
telephony costs.

Among them is traq-wireless Inc. of Austin, Texas.

Its technology cut wireless phone costs up to 35 percent for General
Motors, Continental Airlines and Bristol-Myers by matching workers'
cellular usage with the cheapest plans, company officials say.

One traq-wireless service sends text messages to cell phone users
detailing the name, number and e-mail address of a caller who left a
voicemail message.

Text messaging gets attention
Another company hoping Americans will finally awaken to the utility of
text-messaging with Short Message Service, or SMS, technology is
PocketThis.

Already available in Britain, PocketThis lets cell phone owners send
information they find on the Web -- driving directions, train schedules
and the like -- to their handsets.

Such revenue-producing services are precisely what wireless operators
crave given the huge debts they've amassed.

"The operators are absolutely desperate to drive a bargain," said chief
executive Jerry Roest of Shazam Entertainment Inc. of London.

Shazam's market is people who get frustrated when they hear a song they
like on the radio but don't catch its name or performer. To find out, they
can call a four-digit number and record 15 seconds of the song, which
Shazam's audio pattern recognition technology compares to a database of
1.5 million popular songs.

Callers get a text message with the requested data and Shazam splits the
75-cent fee with the wireless carrier.

All United Kingdom carriers offer Shazam, and Roest is looking for
partners in the United States.

That may take time. U.S. wireless carriers are still developing the tools
that will allow them to bill for such services.

And so far, many analysts say, the carriers have not been very good at
reselling other people's products.

"It's not the technology that's the barrier," said Toby Maners, director
of retail voice in IBM's Pervasive Computing Division. "It's getting the
(wireless) companies to give up their contact with the customer."
