Making wireless pervasive
However companies, municipalities and industries that are actively working to implement Wi-Fi on a broad scale are also helping to make pervasive wireless a reality. For example, the Hong Kong railway system came to IBM looking for a way to implement wireless Internet access on its commuter trains, Keegan said. Metro Stores, a German supermarket chain, is using RFID technology to track goods as they leave the store shelves. Each one of these early applications helps prove the practicality of Wi-Fi technology and will help make pervasive wireless a reality, Keegan said.Chief among them in the United States is that the federal government has endorsed broadband wireless to promote economic, educational and social development. President Bush in particular has "pegged wireless broadband as one of the key technologies" that will help drive future economic groups.

Sensors that record a wide range of data are going to be communicating via wireless networks in the years ahead, he said. While there may be millions of PC users and billions of cell phones in use worldwide, there is a potential for literally trillions of sensors to being put to work to track the performance of a wide range of machines or electronic devices. These sensors will be smart enough to detect problems and record the status of the systems they monitor. They will also act to fix the problem and "will only tell the back-end systems what they achieved rather than what they did" to resolve the problem, he said. Wireless will become pervasive because an ever increasing number of people will constantly be looking for ways to wirelessly log onto the Internet wherever they are. They want to log on in virtually any public space, whether they are traveling, on a business or school campus, or are effectively "held captive" in what Couper called a "wall garden"a convention center, train, plane or automobile where they have no choice but to stay in one place for perhaps hours at a time.

There are several market forces at work driving the demand for wireless broadband services, said Chris Couper, IBMs chief technology officer for wireless solutions.
