CIO — Four out of five Cisco enterprise customers have to shore up their wireless networks, says Chris Kozup, director of mobility solutions marketing at Cisco. Many were caught unprepared to handle the sudden swell of mobile devices—iPhones, Androids and now iPads—during the last couple of years, he says.

"We're going from a period of three years where we saw growth of about 1 billion WiFi-enabled devices to, say, five years where you're seeing a growth of about 7 billion," Kozup says. "Apple has led the pack by really delivering a mobile browsing experience that consumes bandwidth at data rates obviously better suited to a WiFi network."

Flash back to a few years ago, and you'd be hard pressed to find employees carrying more than one mobile device. Now they'll have a smartphone, laptop and maybe even a handheld barcode scanner or other wireless device. WiFi devices also have taken on a greater role in the workplace. "They are demanding mission-critical performance," Kozup says.

Kozup figures 80 percent of Cisco's customers have some work to do to get their WiFi networks in shape, while 20 percent of customer networks are pretty solid.

Organizations in higher education and healthcare tend to rely heavily on their WiFi networks and thus are fairly well-prepared for the mobile enterprise invasion. Consider that the average college student carries four or five wireless devices, Kozup says. Students and faculty at Florida State College, for instance, want iPads for e-books and PDF handouts, as well as other uses.

The iPad and other WiFi devices have also found a foothold inside hospitals, which isn't a surprise given the inherent mobility of nurses and doctors. After all, hospitals are the birthplace of the pager. "There's voice over wireless for nurses, patient call systems, infusion pumps, heart monitors that are WiFi connected," Kozup says. Healthcare CIOs have been on the frontlines of modern WiFi networks, he says.

On the flip side, Kozup says, financial services tend to be laggards when it comes to WiFi network upgrades to the latest and greatest technologies. That's because concerns over WiFi security had kept technology adoption at bay. Traditionally slow technology adopters such as energy and utilities also need to make WiFi upgrades, Kozup says.
