Wireless to the Rescue
Technology Provides Agencies With Innovative By John Makulowich |
Two years before, DARPA had started the so-called Global Mobile Information Systems program. Its goal was to "develop the technologies that will enable military forces to carry out communication and computing tasks free of tethers - that is, cables to power sources or telecommunications networks. The concept of 'untethered' communications unites mobile and wireless operations."
Among the conclusions Goodman and his group reached was that, for a long time, the military had been a main driver of the envelope of technology. One example is radar, originally developed by the military and now used everywhere.
"The major change is that the commercial sector is now driving the show. We refer to this as spin-on rather than spinoff, as in spinning off technology from military uses," notes Goodman.
With the Internet's popularity and penetration across all sectors, he sees the commercial market driving the notion of a wireless Internet.
"Many of us would like to have access to information on the Internet while we are moving around," says Goodman. "There are times when we can't go running to a bookshelf, so there is a need for that.
"However, I do think that the anytime, anywhere model has been exaggerated a little bit," Goodman says. "After all, neither e-mail nor fax is instantaneous."
One model Goodman promotes is what he calls an info-station, which is based on the concept of how a gas station works. You would have enough of these stations so users would not have to go out of their way to use them, but such stations would not be ubiquitous, not absolutely everywhere.
"We need to think the same way about information, going to a station to plug in and retrieve the information we need when we need it. Right now, if you look at the wireless Internet, there are two kinds of people: those who have too much information, are drowning in it or being flooded by it, and those who can't get enough," laughs Goodman.
His WINLAB at Rutgers is working on tools to handle the deluge. One tool, called Alter Ego, is a collaboration with psychology, computer science and engineering.
"The model here is a personal assistant with artificial intelligence, one who learns our habits and the circumstances in which we are computing," says Goodman. "For example, if I'm using my laptop in a hotel room, I would not expect the personal assistant to send me a color photo for my presentation."
Another effort to encourage innovation in wireless along with other types of telecommunications approaches is the Commerce Department's Telecommunications and Information Infrastructure Assistance Program (TIIAP).
The program recently received 757 applications for fiscal year 1998 from all 50 states, the District of Columbia, Puerto Rico and the U.S. Virgin Islands. Applicants requested $323 million in federal funds to be matched by $502 million in nonfederal funds.
Since its start in 1994, TIIAP has awarded 332 grants - over $100 million in federal funds matched by $150 million in nonfederal funds.

Among the projects funded are:
Communitywide networking to the Council of Athabascan Tribal Governments in Fort Yukon, Alaska. Through a partnership, the 2,500 residents of 11 remote Alaskan villages that rely on traditional hunting, fishing and trapping will have Internet access for the first time via satellite connections.
The project offers technical support, training and awareness about the benefits that access can bring to isolated communities.
According to NTIA materials, the primary end users will be tribal members, village council members, village government, community health aid providers, degree program and continuing education students, pre-kindergarten through high school students, school faculty and staff.
Appalachian College Association in Berea, Ky., will guide eight colleges in setting up Rural Information Service Centers in five states: Tennessee, West Virginia, North Carolina, Virginia and Kentucky.
The program promotes economic development in rural Appalachian communities and technical literacy of residents. Each college will develop a specific project.
For example, West Virginia Wesleyan in Upshur, W.Va., will have a van equipped with computers and a wireless link to the Internet, allowing community groups to conduct training programs in many locations.
Valley Emergency Communications Center in Murray, Utah, will allow several cities in the Salt Lake Valley region of central Utah to link their public safety agencies through a high-speed, secure communications system.
The center will set up an integrated data network to link mobile laptop computers in police, fire and ambulance vehicles and manage multi-agency communications using Cellular Digital Packet Data technology (CDPD), a high-speed, wireless communications technology for instant, secure communications among all vehicles through a single dispatch center.
According to Stephen Downs, the director of the TIIAP program, while there has been an interesting variety of wireless projects submitted, his office has not received many of them.
"The potential for innovation is out there with a wide range of wireless technology available, especially CDPD," says Downs. "However, a lot of wireless is not ubiquitous nationwide. You see CDPD in New York City, but it is not seen everywhere around the country. Generally, it is new for the markets it is in."
When looking toward the future, Downs feels the technology trends will favor not transmission technology, but applications. He has also seen the shift in project submissions.
"In 1994, the reviewers were pleased to see proposals for the Internet. By 1995, though, they were saying, 'Oh my, not another proposal for the Internet,' " jokes Downs. "We would not be surprised to see Java [programming language] and CORBA [Common Object Request Broker Architecture] as part of proposals in the near future."
On the cusp of the future is a company like Orion Network Systems Inc. in Rockville, Md., a global satellite communications firm that offers high-speed Internet connectivity and multimedia services to multinational businesses via small receiving antennas. It also transmits video communications for television and other program distribution services.
John Gruehl, federal sales manager, confirms Goodman's view about the military interest in commercial technology, that the government has gone from buying and operating its own satellite resources to leasing existing commercial capabilities.
"It was near the end of the Cold War that the Defense Department started looking at commercial satellites as a viable alternative. That interest increased with Desert Shield and Desert Storm and then the Bosnia issue," says Gruehl.
Part of the interest was stoked by the increase in data requirements, including intelligence and imaging, as well as by command and control requirements.

Set for full deployment by the middle of 1999, three Orion satellites will be able to see the farthest east and west from the United States.
And this is what they feel will be their competitive advantage for the government, that Orion will offer world access through one vendor.
Further, each satellite is designed for advanced data communications, not just traditional voice and voice applications.
Orion's existing Orion 1 satellite, which covers the eastern United States and Europe, has about 10 percent of its revenues from government customers.
According to a company spokesperson, "This number will grow on Orion 1. Once we launch our two new satellites, one for Asia and one for Latin American and Europe as far east as the former Soviet Union, we would expect that our government business could increase to as much as 25 percent of the business on each satellite." n
