Casting a wide Net

Sprint Nextel unveils today its WiMAX wireless network, hoping to saturate Baltimore, and later the nation, in broadband access

Other major wireless companies, such as Verizon and AT&T, are busy developing their own next-generation high-speed broadband wireless networks under a different technology, known as Long Term Evolution, or LTE, which promises to offer even faster mobile Internet connection speeds. But industry analysts say they are at least two years away from offering them to customers.

Sprint's network in Baltimore, on the other hand, is more than half complete and available now to the public, with coverage in large sections of the city and some parts of Baltimore County. The network is also being developed in other cities, including Washington; Boston; Chicago; Providence R.I.; Philadelphia; and Dallas-Fort Worth, Texas. The company has plans to cover 200 million people across the country over the next two years, officials said.

Sprint chose to launch the network first in the Baltimore area for a couple of reasons, said Barry West, Sprint's chief technology officer and president of the XOHM division: It's not too big of a metropolitan area to cover, and the varied geography - from the tall buildings downtown to the thick-walled brick rowhouses throughout most of the city - posed the right challenges for its engineers to overcome. Sprint officials also said the Baltimore area, with about 1.3 million people, was the ideal size for fine-tuning their marketing and customer service efforts before they launch in other bigger cities.

Sprint has lined up a wide array of technology partners - from computer-chip manufacturers to makers of mobile devices - to support XOHM's launch in the United States. Worldwide, more than 500 companies are involved in developing or supporting the technology.

"The whole world is looking at what's going on here, because it is a new business model," West said during an interview and demonstration of the network recently in Baltimore.

"What we want is for people to have WiMAX in everything, including your washing machine, so your washing machine can communicate to its service center whenever it goes wrong," West said. "It could communicate with your [Microsoft] Outlook calendar to schedule service that suits me. That may sound a little far-fetched, but it's not."

Within the next few months, a number of computer manufacturers will be selling laptops that come embedded with specially designed WiMAX chips. Until then, consumers who want to connect to the network will need to buy devices, which start at $59.99, that plug into their laptops or desktop computers. The devices are expected to be sold in stores in the near future.
