"Fixed/Mobile"
Two-way Satellite.
1/25/04 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. 4/18/04 Read Bill Adams' article
about DataStorm: New
Age in Mobile Connectivity. 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. Resources: Photos & information from dashboarders who are in the field & using Datastorm right now! 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 Motorola (update 11/12/01) #9520 (permanently installed in vehicles) #9570 (portable docking station for voice/data phones) #9505 (lightweight handset) |
|
Voice; 2.0K-10.0K for data |
Global service; works in areas not served by other wireless service Predominant application is e-mail or possible return routing for future two-way systems. |
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. | |||
Starband (update 8/29/03) Model #360 Satellite Modem |
$808 |
Upload speed of 70 Kbps to 150 Kbps; Downstream at 150 Kbps to 700 Kbps | Uses GEO stationary satellites. Not licensed by FCC for mobile use. Fixed residential installations only. |
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. |

Flash-OFDM by Flarion |
1-3 Mbps | The technology is based on a new IP-centric architecture 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 data transmission | |

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. | |||
