Since beginning our full-time RV lifestyle, we have
dreamed of having a mobile connection to the Internet.
Wouldn't it be great to be able to travel and camp
almost anywhere and work online at high, broadband
speeds? We've made that dream come true. The photo
above was taken just outside Arches National Park near
Moab, Utah.
-
- Up until recently, the best option we
had was a DirecPC
satellite - - a one-way satellite
service requiring a phone connection to
handle outgoing signal transmission to a
service provider (EarthLink)
and giving us Internet-down via our
receive-only dish. Download speeds were
relatively fast, but the landline phone
yielded slower outgoing speeds. Moreover,
the phone had to be connected for the
entire Internet browse time. This system
gave us Internet access anywhere that we
could find an 'instant
phone' connection to our campsite. We
made do with this system for 2 1/2 years,
but we kept looking for something
better.
-
- We found the solution at a Salt Lake
City company called MotoSat. Before we
explore the most effective solution, let's
explore all the things we've tried.

- Ineffective Internet Solutions
- What we needed was high-speed wireless Internet
access. In that vein, we had earlier explored three
categories of technology: (1) cellular phone, (2)
mobile email devices, and (3) satellite-based systems.
In the first category, cellular phones, we found the
range and speeds to be limited. We tried the Nokia
cellular modem using a data-capable cell phone that
was plugged into a cellular-capable modem, in this
instance a PCMCIA type (credit-card size that fits
into most laptops or internal PMCIA drive installed
into desktop). Some phones can be purchased with a
built-in modem and data cables that connect directly
into a computer. We also tried a wireless modem from
Sierra
Wireless. Also quickly ruled out was satellite
phone technology such as that provided by Globalstar.
Here the equipment resembles a cell phone - - only
larger. The problem here, was that after the initial
equipment costs and monthly fees were met, the
per-minute based surcharges were too exorbitant for
our extended use.
-
- In the second category we found the mobile email
devices. Although mobile, these also did not support
the type of rigorous Internet use that our occupations
require. The most common application, PDAs (Personal
Digital Assistants), are small handheld devices that
can be used for mobile Internet access - - for example
the Palm
Mobile Internet. Some have an optional wireless
modem that work on the existing cellular network. All
face limitations and speed issues comparable to
accessing the Net over a cell phone. This confines
their usefulness largely to email. The viewing screens
are too small and speeds too slow for surfing the
Net.
-
- Our technology search found that equipment costs,
monthly service fees, and surcharges varied; but for
us, the determining factors were that connection
speeds to the Internet were too slow especially in the
regions away from major metropolitan areas. Browsing
web pages was largely out of the question. Part of the
problem was in the linking of the Internet service
provider to the wireless technology provider, whether
it be cellular, satellite, etc. We did not find a
feasible solution for our moderate to extended levels
of use. We are often stay online, eight to ten, twelve
or more hours a day. That left satellite technology
with the most promising potential for high-speed
connections plus portability.

- The Two-Way Satellite System Solution
- Early in 2001, two companies, DirecPC
(DirecWay) and
Starband, began
to market long-anticipated two-way satellite systems.
In order for any satellite dish to both send and
receive signals, the alignment between the dish and a
satellite must be absolutely precise. Scott Whitney
(Mobile Internet Access, November 2001)
compared this process to "trying to aim a flashlight
at an object the size of a Honda located 22,000 miles
in the air" (p48). Because of this required precision,
neither Starband or DirecPC have supported a mobile
application of their dishes. Both insist that
certified installers must bolt the purchased dish to a
fixed structure. Before giving up on that avenue, we
made contact with DirecPC and their two training
centers for installers - - seeking to find if there
was a feasible way that we could use this two-way
technology in our lifestyle. Even if we could have
been allowed to complete the one-day training and
receive the FCC certification, the process is
supported by a phone connection at the time of hookup.
However since then, we have heard reports of at least
two 'wildcatters' out there who are aiming and
aligning these systems, one reported as using Starband
and the other a DirecPC unit. No doubt there are a few
others doing the same thing, but the extended setup
times required and the risks of pointing and sending a
signal to the wrong satellite are obvious.
-
- The cost of these dishes range from $300-$650
dependent on choice of features and promotions. Their
installation usually runs about $200. Users also are
required to pay a monthly fee, around $50 for
Internet. Inclusion of television programming into the
system increases the monthly fee upwards to $90 or
more. The service area covers the lower 48 states and
beyond, including much of Canada and Mexico. As with
any satellite system, rain, snow or even heavy cloud
cover can affect satellite performance.

- The MotoSat Solution
- What we were really looking for was a
'moveable' two-way satellite system. In
other words, we weren't looking for a
system that allowed wireless Internet
connection as we moved down the highways.
We wanted a system we could move anywhere
our motorhome could go without a phone
hookup.
-
- This is the point where we learned
about the development of the DataStorm
2-way satellite system from MotoSat
of Salt Lake City, Utah. In August 2001,
we discovered the MotoSat website. They
were developing a dish for mobile
applications. Since then they have built
and are beta-testing a dish called
DataStorm that currently uses the DirecPC
system and will eventually be developed to
also work with the Starband satellite.
This moveable two-way satellite contains a
motorized version of the DirecPC dish
along with specialized positioning
software.
|
- In August, we jumped at the chance to apply to
'beta-test' the first version of the DataStorm system.
By mid-October, we learned that we had been selected
to join the Beta Test Group. In November, we were able
to make the trip with our motorhome to Salt Lake City
in order to have the system installed. And for about
six months, we have been using the system to work
online - - to browse and research via the Web, to
frequently ftp files (upload) to our website, and send
and receive our email communications. We use the
system with our networked computers in the motorhome;
the server is a Dell PC and we connect to a Macintosh
workstation and Apple laptops. Speeds vary, determined
by our service provider, but even at the slowest
connection, they are faster than anything we ever had
before. Our connection speeds measured at 'Bandwidth
Tests / Speed Tests' from Bandwidth Place
have ranged from as low as 253 Kbps to a blazing 1413
Kbps (faster than a T-1). We usually are in the four
hundred to six hundred level.

- Our DataSorm unit includes a
roof-mounted dish, upper and lower control
units that include a global positioning
system and an electronic compass . . .
enabling the system to automatically seek
and find the satellite and configure the
system for continuous operation. The
system is also configured to receive
DirecTV satellite television programming
at the same time we are online.

In our visit to Salt Lake City, we found MotoSat to
be a dynamic, entrepreneurial company. We met and
talked with everyone at the plant, from President to
Software Engineers to Installers. Each shared their
viewpoint and answered our many questions. Their team
is working together to bring this dish to market in a
few weeks.
-
- The system is expensive but once the
hardware and installation costs are
absorbed, our monthly service fee is the
internet access and DirectTV charges. For
now, this is lowest-cost two-way satellite
service authorized and supported for use
in a mobile environment. Note that
Tachyon
does provide a very high-end, high-speed
system that is currently used by Wells
Fargo Bank. The equipment is expensive
and also carries a high monthly service
charge making it an unlikely option for
most mobile applications. The future will
likely bring other competitors like
WildBlue
(Due in 2003) or Teledesic.

Oh yeah, now we can park the motorhome and
do our online work almost anywhere - - that
is if we don't park underneath trees! Of
course, that wasn't a problem when sitting
near the Little Book Cliffs Wild Horse Area
outside Grand Junction, Colorado. We managed
to find a nice spot next to the Colorado
River surrounded by beautiful mesas.
