"Fixed/Mobile"
Two-way Satellite.

Dashboarder Ron Bunge's field report from South
Texas!
Click here.
In June, 2002 the FCC licensed Hughes Network
Systems (HNS) to provide two-way mobile internet
connectivity under the DirecWay gateway
and MotoSat's dish/receiver technology.
There are a variety of vendors selling the service
under brand names like Datastorm.
Hughes DirecWay also supplies service
to iNetVu, a Canadian firm (& competitor
of Datastorm)[More
info about iNetVu]
|
$3995, Dish, Mounting
hardware and automatic targeting acquisition software.
Installation Costs: List price is $1000, but some
dealers are installing units for $500
Monthly Internet Service: $99 to $500/month. Marketed
as "unlimited access" but per-month
charges are based upon bandwidth usage each month.
(**See notes below)
|
A January 2004 Field Test reported average
upload speeds of 70 Kbps & 1000 K bps download.
During the test, uploads as low as 8 Kbps and
as high as 1787 Kbps were observed.
Networks: MotoSat will be releasing (in 1Q
-04) an external network connection box that
enables networking of up to 15 computers without
needing a PC/server.
|
First true 2-way data
satellite product for consumers. Software is designed
to raise and aim the dish, target and acquire
the proper communication satellite without manual
programming by user. In most cases, user can be
online within 8-10 minutes of clicking on the
satellite icon on the PC screen.
System is VPN capable, but requires additional
software to lessen the effects of latency (potential
connection failure caused by the extreme distances
between satellites and the earth).
|
The service employs a 39"
by 24" oblong satellite dish that can be
used to access both the Internet and TV programming
that is mounted on an aluminum platform and
controlled by a 11"x9"x1" controller
that is connected to a PC (minimum 500 Mhz).
The Datastorm software completely controls the
entire targeting and signal acquisition process
from inside the vehicle. The vehicle must be
parked when the satellite receiver is being
used. Excessive movement of the vehicle will
result in a stowing of the dish by the software.
In the stowed position, the satellite dish is
only 10.5" tall. The dish can sustain a
40-mph wind and can operate in both rain and
snow storms.
By licensing agreement, there is no "consumer
version" of this service, but any person
can purchase and use the "Basic Business"
service. There are some coverage problems in
Alaska and northern Canada, but generally access
is possible throughout North America. VPN and
multiple user configurations including the use
of wireless LANs in the area surrounding the
vehicle are possible with this service. The
major differences among vendors are the degree
and implementation of customer support. The
market leader is Ground
Control in this regard.
**Monthly Internet Service: The basic level
of service costs $99 per month (many dealers
offer first three months free) and is considered
"unlimited access," but is subject
to a "Fair Access Policy" restriction.
In the event that a user were to download more
than 500 Mb in a four hour period, the access
speed for the service would be downgraded from
400 Kbps to 56 Kpbs for 12 hours and then the
service to the higher speed would be restored.
Most users will not exceed this 500 Mb limit
but there are higher monthly access plans allowing
up to 1000 Mb of download if required. Dashboarder

Adams, who installs DataStorm systems on
the road, suggests this resource: Insider

satellite systems.

about DataStorm: New
Age in Mobile Connectivity.
For more information and photographs of installed
Fixed/Mobile applications check out:MotoSat's
DataStorm, and Ground
Control's "Broadband Internet Anywhere".
TV Service is available through
Dish network (starting at $30/month) or DirecTV
(starting at $32/month). A satellite receiver
is required--an existing receiver works, or
a new one is usually under $100.

FIELD REPORT 5/22/03: Ground
Control owner Mark Wright phoned RoadTrip America
via VOIP (voice over Internet) from "the
middle of nowhere," (actually somewhere
east of Ely, Nevada) and described his field
test results using the Hughes DW4020 gateway.
He dowloaded files at speeds approaching 1.8
Mb! The cost of the new gateway is about $700
more than the standard DirecWay modem.

| Iridium
uses LEO satellites which require smaller transceivers.
Iridium (post-bankruptcy) re-launched voice service
on 03/28/01. Cost information for the handset and
service plans remains very difficult to substantiate.
Basic handset operation allows for a dial-up data
connection at ~ 2.0 Kbps. Iridium is also supporting
a "Direct Internet Data" service which
uses a compression program and an emulator protocol
in an "always on" mode, so that PCs (connected
to an Iridium handset) can send and receive data
through a dedicated (for data use) gateway on the
Iridium system. Service is consistent with through-put
found in analog (1G), but it will work in areas
not served by 1G phones. To reduce transmission
costs , this service employs "spoofing,"
which is supposed to be able to disconnect and re-connect
automatically when data is being sent. Pricing will
be updated when information is available. |

speed of 70 Kbps to 150 Kbps; Downstream at 150
Kbps to 700 Kbps |
Uses

After a brief and unsuccessful alliance with nationwide
retailer RadioShack in early 2001, Starband is now
only available through third party installation
companies. Must have unobstructed view of southern
sky. Must have Pentium PC processor in excess of
200 MHz. Pricing includes 12-month service agreement,
required hardware and software, a 24" x 36"
transceiver antenna, and required installation by
FCC-certified installer. (For
more information click here.)
8/29/03: Field Test from Dashboarder Ron
Gillentine at a fixed location near Lake Isabella,
California. Reports that thunderstorms in the area
frequently break connections, although reconnections
are made quickly and automatically. Ron also reported
that electrical storms near the system uplink near
Atlanta, Georgia, can cause temporary loss of signal.
At RTA's request, he ran throughput bandwidth tests
using the C|Net and 2Wire testing protocols. Both
testing programs showed consistent service in the
528K to 630K range on August 29, 2003. |

**Service plans require 12-month
service contract. TracNet 2.0 employs the Canadian
Bell ExpressVu DirecPC system for
providing Internet access. Since this product
employs an 18" receiver, it requires low-speed
data connectivity. It features an on-board wireless
server and capability of connecting laptops and
other PCs to the satellite feeds by 802.11(b)
networks. TracNet 2.0 is currently the only high-speed
(download) in-motion Internet connectivity system
available to consumers. At the CES show in January
2003, KVH unveiled a phased-array TV antenna that
is only 4 1/2 iches tall. Software to enable TracNet
2.0 for use with this antenna is currently under
development.
*Compatible with DirecTV and ExpressVu,
TracVision S3 appears to be a direct competitor
with Hughes' "Fixed Mobile" and DirecWay
service.

rather than the circuit-switched networks used by
CDMA/TDMA/GSM. As a result, the latency issue is
very low and allows for peak high-speed bursts of

| Orthogonal
Frequency Division Multiplexing (OFDM) was originally
developed in the famous Bell Labs, divides a range
of available bandwidth spectrum into a series of
frequencies known as tones. Flarion's system can
be tuned using frequencies below 3 GHz and divides
each channel into 400 discrete tones (each at slightly
different frequency). Orthogonal tones do not interfere
with each other when the peak of one tone corresponds
with the null. All frequencies fade, but the rapid
switching, frequency-hopping technique is supposed
to allow more robust data service. In Q4-2002, Flarion
is planning to deploy radio base stations on existing
cell towers to serve the 800 and 1900 MHz cellular
frequencies. The technology enables communication
with no interference with existing CDMA or TDMA
signals. |

| Blue Tooth
is the name given to a specification for a wireless
communication chip used for the transmission of
voice and data. It is expected to be low cost (at
less than $6 per chip), short-range, (30 feet) radio
link that has been envisioned as cable-replacement
system. Operates in the un-licensed 2.4 GHz range.
Blue Tooth uses fast frequency-hopping technology
to avoid interference from other radio signals when
it transmits packets of data. Can be used as the
interface to download e-mail from high speed wireline
network to PC using PC card (click
here for article with more info). Cost of the
chips now $50, too expensive for most applications. |
