From the editorCommentary by Pen Computing Magazine's editor-in-chiefBy Conrad H. Blickenstorfer November 2000, issue 36
Believe it or not, but it looks like this is the year where wireless
communication is finally starting to take off. You've heard this before, of
course, and more than once. In fact, pretty much each of the past several years
was supposed to be the year of wireless communication.
In 1994, for example, Motorola introduced the Envoy, a nifty handheld
device with an ARDIS packet-switched radio, and called it a "PIC" which stood for
Personal Intelligent Communicator. It used the friendly Magic Cap operating
system, and General Magic talked about little kids walking around with Envoys
getting "post cards" from their pals. The Envoy was remarkable device,
butÑalasÑit was several years ahead of its time. Its failure was a combination of
factors: high price, spotty service, and a public not quite ready yet for a
handheld without a keyboard.
Before the Envoy there was the EO, a device built around the brilliantly
conceived PenPoint operating system. Some EOs came with integrated cellphones,
and that was quite remarkable for 1993. The EO was thus a wireless communication
device. Unfortunately, it was also positively huge by today's standards, and its
full-size telephone handset alone probably weighed more than two Palm VIIs. AT&T
became the subject of much ridicule for its EO "Fax on the Beach" commercials.
Back then it was far-fetched to imagine someone taking a portable computer to the
beach to do work, much less one equipped with wireless communications
capabilities. Turns out that AT&T was right after all. You can fax on the beach
today, and it's no big deal.
A few years later we saw several handhelds equipped with CDPD radio
modems. None were a commercial success. The only thing wireless that really
worked were industry-specific business solutions from the likes of Symbol,
Telxon, Norand, and some of the other vertical market leaders.
So what makes me think that wireless is making its move after so much hype
and so many false starts? It's not as if we all of a sudden had some magic new
wireless technology at our disposal. We're basically still dealing with the same
old networks, the same old fragmentation, and the same multitude of incompatible
standards and protocols that have left the United States well behind Europe and
Japan, and a good number other industrialized (and even some not so
industrialized) nations.
While it's true that CDPD service has been built up faster than some
experts expected, many wireless devices still use the same old ARDIS and RAM
packet-switched networks that were here well before the Envoy and the EO. They
now have different names and owners (ARDIS first became American Mobile, then
Motient, and RAM Mobile Data is now known as the BellSouth Intelligent Wireless
Network), but the services are basically the same. CDPD, likewise, hasn't
changed. We're talking low bandwidth and low speed communication here. Nothing
even close to a 56k wired modem. The same goes for the circuit-switched GSM and
CDMA data systems. We've also seen some spectacular failures, like the much
ballyhooed worldwide Iridium satellite network that was shut down earlier this
year. The networks and their technologies are really not the reason for all this
new attention.
The real reason is that we're starting to see intelligent use of wireless
service. Vendors have finally realized that web browsing on a notebook computer
with a 19.2kbps wireless modem is not a pleasant experience. As a result, we're
now seeing solutions that were built with the strengths and limitations of
wireless in mind. The Palm VII demonstrated that you can not only have wireless
email in a very small device but also get meaningful data from the web through
Palm's clipping technology. RIM's interactive pagers quietly built a significant
following pretty much through word of mouth. How can you argue with an email
device that is always ready to send and receive messages, yet can still go for as
long as a full month on a single charge? Wireless web access, once an exercise
in frustration, is made possible in a number of ways. Many large site offer
special text-based and condensed versions of their content. A growing number of
back end services condense standard web pages on the fly and reformat them for
display on small handhelds. Yet others have arrangements with a number of
websites and offer their content, reformatted, through their web portals. A great
example of such a service is OmniSky.
Accessing these services does not require a desktop browser like Internet
Explorer or Netscape. A new generation of largely text-based micro-browsers make
web access possible even on the tiny screens of a new generation of Internet
phones. "WAP" (Wireless Application Protocol) has become quite a buzz word. WAP
devices require content to be coded in special languages such as HDML (Handheld
Device Markup Language) or WML (Wireless Markup Language). As the bandwidth of
wireless networks grows, we will undoubtedly see larger screens, graphics, and
even animation.
The point, though, is that wireless is taking off because the service
providers have learned to live within its constraints. Consumers are now getting
real value from services that are actually useful. And this goes well beyond the
stock quotes or weather reports paging systems have been able to send to their
subscribers for years. We're talking real two-way interaction with web-based
services through handhelds and WAP phones.
I recently attended DEMOmobile 2000 in Pasadena. The show, produced by IDG
Executive Services (www.idg.com), is a terrific place to learn about the hottest
developments and trends in the mobile and wireless space. It confirmed what I had
already seen at last June's PC Expo in New York: PCs and notebooks are boring. So
they have a faster processor and a bigger disk than last year. Who cares? Today
it's all about mobile devices, wireless communication, new services, enterprise
integration, and, of course, the web. There are hundreds of startups with great
new ideas of how we can increase our productivity and make better use of our time
by building a worldwide wireless community where you're always connected. The
demos I saw at DEMOmobile showed that many of those services and ideas are
totally feasible and can work with today's Palms, Pocket PCs, RIMs, and WAP
phones. I saw digital cameras that snap onto cellphones to transmit pictures to a
special imaging portal where you can enhance the pictures and send them to your
friends and relatives. Palms can be used to buy and pay for tickets online, and
the ticket is then transferred to the Palm for redemption at special "Internet
Fastlanes." Read about it on my report on DEMOmobile on page 38.
I should also mention that the handheld device of choice for most of these
new services is the Palm. That's partially due to the sheer number of Palms out
there, and partially because despite its brilliant simplicity, the Palm OS has
proven to be remarkably versatile. There is also growing support for the RIM
platform That's likely because all RIM devices are wireless already, so
developers don't need to worry about different wireless services or modems. Just
about everybody seems to support WAP these days, to the extent where Psion's
upgrade of its Revo handheld now contains a WAP browser in addition to a more
elaborate "real" browser. Amazingly, wireless is one area where Microsoft lags
behind. Pocket PC and Windows CE support usually comes after Palm, RIM, and WAP.
Despite all of these developments, we're not quite there yet. While those
who carry a Palm VII, a RIM device, or an Internet enabled phone enjoy better and
almost instant access to a growing number of services and resources wherever they
are (as long as there's coverage, of course), the rest still need some sort of
wireless connection for their handheld. That can be done via many cellphones, but
I've never been fond of dial-up data services, especially when they go over voice
networks that are designed to carry the maximum number of subscribers at the
lowest transmission quality possible. Novatel Wireless, who makes the terrific
Palm V cradle used by OmniSky, has been showing similar attachments for some of
the Microsoft powered handhelds. Over the next twelve months we'll be seeing some
interesting new wireless hardware solutions.
The emergence of wireless access is a good thing as good old-fashioned
modem connections are becoming more and more of a pain. It's become almost
impossible to get a reliable connection on the first try. In addition, it puzzles
me that current Pocket PCs do not have internal modems. Older CE devices and
palm-size PCs had internal modems and RJ-11 jacks. Where did they go? I really
resent having to use a cradle, a bulky CF Card modem, or be plain out of luck as
I am with my (otherwise wonderful) Compaq iPAQ because I cannot find an expansion
sleeve anywhere.
