The five biggest worries about mobile data

Concerns about EV-DO, 3G that keep network executives up at night

When companies consider rolling out mobile-data applications, several issues always come up that strike fear in the hearts of CIOs, who don't want to make major investments in an emerging technology that later proves to be unreliable, insecure or proprietary.

Here's a list of enterprises' five biggest concerns in the US about Evolution Data Optimized (EV-DO) and other 3G technologies and what the US telecommunications industry is doing to alleviate them.

Worry number 1: Performance

What's the point of buying high-speed wireless data services for your employees if the network doesn't reach your branch offices or customers? That's why one of the first questions that network executives ask is about coverage and speed.

"If you have great speed but you're in four markets, then enterprises don't want that," says Tim Donahue, vice president of business marketing for Sprint Nextel. "They want ubiquity. At 80 percent of the U.S. population, you are definitely there. Then you can add on the remaining locations. Enterprises want to know that wherever they are, you are there."

Wireless access has to be not only available and fast but also reliable -- not necessarily the 99.999 percent reliability that companies have come to expect from traditional wired networks, but reliable enough for their applications.

"We've seen more emphasis on reliability for business users in the last six to 12 months," says Mike O'Malley, director of external marketing at Tellabs, which sells wireless data equipment to carriers. "This really raises the stakes for the carriers. They have to make sure they have coverage -- not just in any building but in the canyons of LaSalle Street. They need to make sure that the call is not going to be dropped because it's being used for very important, time-sensitive information and financial transactions."

Carriers say the best way for companies to determine whether a wireless data service performs well enough for their applications is to test it. "We tell CIOs to trial EV-DO for 30 to 60 days and then make a determination," Donahue says.

Wireless network performance is becoming more important to enterprise customers as they move beyond e-mail to more critical business applications such as real-time ordering and inventory management.

CIOs care about "the level of service that the mobile operator can provide in resolving potential issues that will arise in terms of application performance delivery," says Jim Vale, product manager at Network Genera, which sells sniffers and other network management devices to wireless carriers to help them isolate problems on their networks. "As data is pushed out to the mobile service offering, the enterprise really has very little or no visibility into that last mile. And it's a very long mile."

Worry number 2: Security

Given the publicity surrounding compromised customer data caused by lost or stolen laptops, CIOs are rightfully worried about managing a fleet of mobile devices.

That's why there's growing interest in managed security services from wireless carriers that include dealing with lost or stolen devices, as well as repair and replacement of broken devices.

"There's amazing growth in the use of laptops in corporations," says Jim Szafranski, vice president of product management and marketing at Fiberlink Communications, which sells remote access software. "Corporations do want to provide easy connectivity for their users . . . but the concern is that the laptop is harder to secure. IDC has a statistic that 60 percent of all corporate data is on laptops today. So that's a worry."

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
