Now that we all have laptops and AccessPoints equipped with 802.11b gear mecca has become a mobile source for internet access. Until recently there have been very few sources for this, now a few are starting to emerge. -- AdamShand

Here are some resources for a SatelliteTruck:

Cellular 3G service seem far more practical for mobile access. It has one big drawback - cost. If 1XEV-DO (Data-Only) were available in Portland for $50 "wireless DSL" as it is in Seattle, that would seem to be the clear choice for mobile, high-speed backbone connections from a van.

-- Satellite Carriers include:

[http://www.hns.com/direcway/for_small_business/business_edition/intro.htm Hughes DirectWay] and [http://www.hughes.com/home/transition/states.xml Spaceways] with 384K-6M/up/down in Ka by 2002

Satellite carriers like [http://www.cyberstar.com/ Loral's CyberStar] skip most of the congestion of the terrestial internet for Enterprise users and ISPs. [http://www.cyberstar.com/products/products.cfm?pageID=clearstreamlive Loral's ClearStream WebCast] is available in packages of 100, 500, 1000 and 2000 simultaneous live users at a variety of data rates including 56 Kbps, 100 Kbps and 300 Kbps.

Other satellite carriers include: [http://www.tachyon.net Tachyon] [http://www.cidera.com Cidera] [http://www.hughes.com/home/transition/states.xml DirecWay] [http://www.ibeam.com i-Beam] [http://www.microspace.com/index2.html MicroSpace] [http://www.panamsat.com/media/pressview.asp?article=1160 NET36][http://www.ico.com/system/index.htm New ICO][http://www.pgtv.com/default.asp?flash=true Pegasus]

[http://industryclick.com/magazinearticle.asp?magazineid=5&releaseid=6901&magazinearticleid=115349&siteid=3 Here's a story on Wild Blue]

..."Wild Blue says it will be about 3 Mbps/400 kbps in speed. How does that compare with the other players in consumer land? Hughes' DirectPC is 400 kbps/56 kbps using a dial-up phone line to communicate requests, while Star Band is not much better at anywhere from 150 kbps (heavy load/many users) to 500 kbps download, 40-60 kbps upload. The [http://www.motosat.com/twoway_001.htm two-way Motosat dish] (below) automatically finds the DirectWay consumer satellite service ($70-$90/mo) on the road.

A Wild Blue setup consisting of a small modem and a 26-inch dish will be able to connect up to eight devices in the home PCs, TVs and other Internet-enabled devices. Your price for admission has yet to be determined, but according to the Web site, Pricing is expected to be competitive with DSL and cable modem service. It will be flat-fee, so you won't have to worry about bits set or time spent online..."

It is anticipated that [http://www.hns.com/products/advanced_platforms/spaceway/overview.htm SpaceWay] and [http://www.wildblue.com/ WildBlue] will offer 30Mbps, Ka band satellite services via spot beams in 2003 for $1000 - $2,000/month and consumer-level service with 400K up and 3 Mbps down for $50-$100/month.

A wireless link from the Van to OHSU or the KGON tower could provide a high-speed MAN in lieu of remote, high-speed satellite or 3G access. A short leased line from OHSU to the Pittock Building might be utilized. The unlicensed 2.4 or 5 GHz band could supply a 22-54 Mbps backbone. A van with a 2-way dish could also be semi-permanently assigned as a hilltop "Teleport" for PersonalTelco or provide emergency back-up.

Satellite backbones have latency issues but sharing 5 Mbps downstream link that would cost $200/month might be shared by 100 people. That lowers the cost to $2/month. "Unplugged expeditions" might be infrequent. The capacity would normally be shared. It would also be used for emergency backup. Cost sharing with other groups (like hams) might also be feasible.

Spot beam satellite platforms like [http://www.wildblue.com Wild Blue], and [http://spaceflightnow.com/news/n0111/18bssspaceway/ SpaceWay] will lower cost. [http://www.house.gov/smbiz/hearings/107th/2001/010524/cook.html SpaceWay] expects to serve 1 million businesses with satellite broadband. If 500 people share a $1000/month satellite connection with [http://www.hughes-escorts.com/mediaroom/HNSEarnsAward.htm 3 Mbps up and 30 Mbps down] cost per user would be $2/month.

Spaceway also provides [http://www.convergedigest.com/satellite/archive/010918boeing.htm full-mesh connectivity], allowing users to communicate on a single-hop, peer-to-peer basis for collaborative interaction.

A shared 2-way dish located at OHSU (about 1000 feet above sea level) could also be accessed via [http://www.wmux.com/company/news/2001/091001Multipoint.html 5.8 GHz unlicensed bridge] that would be mounted on the van. [http://www.wmux.com/company/news/2002/011602Proxim.html Western Wireless], which merged with [http://www.proxim.com/ Proxim], offers a wireless solution. Their [http://www.wmux.com/company/news/2001/091001Multipoint.html Tsunami Multipoint] can support 6,000 subscribers per cell site using the 5.8 GHz frequency band at 60 Mbits/second. It complies with the emerging IEEE 802.16 standard for broadband wireless access. This wireless backbone solution delivers connectivity for nodes on roof-tops, utility poles or a van. A 60 Mbps base station (at OHSU for example), costs $10,000 while the 60 Mbps receiver unit (in the Van for example), costs about $2,000.

The community might also be served from this 60Mbps wireless backbone.
