The Road Wirer
Anything
New Up There?

In
the last few days, I have received numerous queries about
"new" satellite services, (DirecPC and Gilat-to-Home)
which are supposed to start delivering two-way Internet access
within a few weeks. Since identifying a communication
system that can deliver the means for Dashboarders to connect
to the Internet at a reasonable cost and speed from anywhere
is the primary focus of the Road Wirer columns, here is my
take on this "news."
Many wireless communications offerings already exist for business
enterprises that maintain fixed business locations and are
endeavoring to use wireless devices and services to connect
their employees in the field. But a growing number of
entrepreneurs are looking for methods and services that will
allow them to cut the cord with the land-based infrastructures.
Journalists, writers, editors, photographers, medical transcriptionists,
software designers, consultants, analysts and sales persons
represent just a few occupations held by people who pose questions
about wireless options to us on a weekly basis. The
focus of the Road Wirer commentary is therefore directed toward
finding solutions for individual users and not towards those
companies that can afford to create and implement their own
proprietary wireless systems.
First of all, as of this date there are only a couple of two-way
satellite options available for individual mortals.
Both of these, Tachyon and
the various Immarsat options, utilize geosynchronous
satellites, and neither of them pass the Road Wirer criteria
because they either exceed the standard for reasonable cost
or they can not be used in mobile settings. Neither
the Hughes Network "DirecPC"
or the Dish Network's Gilat to Home are operational and therefore
remain in vapor-ware status for the time being.
There are a couple of Web sites that provide excellent
information about satellite issues and systems. The
first is the glossary
of satellite terms that Satellite News On-Line has produced.
Lloyd Wood is an English researcher who has created a remarkable
database of information and links about current wireless options.
On my last visit to his
Web site, I found interesting tidbits like the fact that
the Bill Gates' Teledesic "Internet in the Sky"
project public launch has rolled into the future to at least
2004. Plus there is an excellent discussion about latency
(time-delay) issues and GEO (Geostationary Earth Orbit) systems.
In the "far-out" category, I would suggest looking
at the latest from the Sky Station "Balloon", the
under-sea network FLAG (FiberOptic Link Around the World),
and the high-altitude aircraft options as alternative methods
to conduct wireless access to the web.
Getting back to Dashboarder reality-- there is only one two-way
satellite system that I know from personal experience actually
works. It is not the definitive Dashboarder solution
because the data transfer speed is slower than we prefer,
but the Road Wirer field trials conducted a few weeks ago
proved that the Global
Star system provided us access to the Web in remote
(non-cellular) areas of Death Valley National Park.
Next week: results of our GlobalStar field trials and discussion
with the founder of Tachyon.net.
