One more mile to go: Lucent boosts novel TeraBeam scheme
A deal this week between Lucent Technologies, based in Murray Hill, N.J., and TeraBeam
Networks, based in Seattle, places attention on the last mile in data's winding
journey. Companies often pay substantial sums for optimal bandwidth; but if high-speed
fiber conduits do not actually make it all the way to their door, those expenditures
can be for naught. TeraBeam uses holographic receptors that can be positioned on window
sills to receive data. With communications powerhouse Lucent's backing, its novel
methods will bear more consideration. Still, some analysts question whether TeraBeam's
throughput claims are fully merited.
This week, Lucent and TeraBeam Networks hammered out a plan to jointly develop and
deploy a TeraBeam wireless service that beams data through the air at speeds as fast as
1 Gbps (gigabits per second), writes Cathleen Moore in an InfoWorld story.
TeraBeam's Fiberless Optical service, which was first announced last month, attempts to
solve the last-mile bottleneck of getting data and services from wide area to local
area networks, she writes.
TeraBeam's service beams data wirelessly from strategically located POPs (points of
presence) in metropolitan areas to transceivers that can be mounted in office windows.
The two companies said that in addition to jointly developing TeraBeam's service,
Lucent and TeraBeam will pool resources to create a new systems company that will
deploy TeraBeam's technology. TeraBeam will own 70 percent of the company -- called
TeraBeam Internet Systems -- and Lucent will hold the remaining 30 percent.
"With TeraBeam and Lucent together, they will provide a wireless metropolitan area
network that runs at gigabit speeds," said Christopher Nicoll, director of optical
infrastructure at Current Analysis, based in Sterling, Va. "It should let enterprises
see multimegabit and gigabit rate service much more quickly."
Dead end for streets of fiber?
"Even if streets are getting dug up for fiber-optic access, that doesn't necessarily
mean that it's bringing service to your building. With TeraBeam, if you want
service, 'you' can get it in a matter of days or weeks," Nicoll told InfoWorld.
TeraBeam said that a prototype of the service has been used on a trial basis for the
past 18 months in Seattle, and the company said it plans to roll out service in three
more cities by the end of the year.
According to Nicoll, Lucent's established optical presence will give TeraBeam's
technology a push into the marketplace. (Read a href="http://www.infoworld.com/articles/en/xml/00/04/12/000412enteraluc.xml">more

New beam in perspective
Still, service providers that buy into TeraBeam's fiberless optical technology with
hopes of living a gigabit dream could wake up to a megabit reality.
Reports on the TeraBeam technology essentially lacked detail, writes Stephen Saunders,
US Editor for LightReading.com. "No price was announced, and neither vendor
would give specifics on throughput, range, or indeed how TeraBeam's laser-based
wireless technology works," wrote Saunders in a piece published on Network
TeraBeam says its product supports "gigabits per second speeds." However, on closer
examination it turns out that the capacity of the network is shared between
subscribers -- a fact confirmed later by TeraBeam. That means that service providers
that deploy services based on TeraBeam technology, and businesses that buy into those
services, are more likely to see megabit speeds than gigabit throughput, Saunders has
concluded. (Read a more
